After a tiring research of over 40 hours, we’re more than confident that the Mi Air Purifier 2S is the best budget air purifier for most people in India. If you are looking for greater protection against allergies or want your air purifier to cover a larger area then Philips 3000 Series AC3256/20 Air Purifier is your best pick.
Buying an air purifier to keep yourself and your family safe from the high levels of air pollution? This air purifier buying guide aims to help you in buying the best air purifier for your home.
The WHO global air pollution study conducted from 2008 to 2016 reveals that India has 14 out of the 20 most polluted cities in the world in terms of PM10 and PM2.5 concentrations. This is not only a matter of shame for us but it is dangerously alarming.
This increasing level of air pollution is posing a very big threat to the health and well being of most Indians. Hospitals are flooded with patients suffering from minor to major complications like breathlessness, coughing, throat infections, chest pain, irritation in eyes, allergy, and asthma.
The situation becomes even more severe during winters because of the thick layer of smog. And the situation is getting from bad to worse every year. Whatever steps the Central and the respective State Governments have taken, they have shown very little impact in improving the quality of air.
Thus it becomes very important that we ourselves employ measures, to fight the severe level of pollution, and to keep ourselves and our loved ones as safe as possible.
There are 2 things that you can immediately implement to counter this horrifying situation. Wear PM2.5 masks whenever you are outside and use air purifiers when at home or office.
But why do you need an air purifier when there is no pollution in your home?
If you too are wondering the same then you are not alone as most of us tend to think that the air inside our homes is clean.
When we think of air pollution, the first things that come to mind are industrial, construction, vehicular, crop burning and other kinds of outdoor pollution.
But, have you ever wondered how polluted is the indoor air that you breathe in your house?
Most of us spend up to 90 percent of our time indoors (whether in the office or at home) and most of the air we breathe is “indoor air.”
Several studies have revealed that the indoor air can be as much or even worse than the air outdoors. There are actually various sources of pollution that have a negative effect on air quality, many of which are found in our homes and offices. From cooking residue to paints, cigarette smoke, pet dander, pollen, toilet cleaners, dust, varnishes, and insect repellents, the air we breathe indoors is often more polluted than that outside.
Therefore it becomes necessary to employ some measures to keep the air inside our homes and offices clean. Air purifiers are the easiest and most effective ways to achieve clean air inside your home or office.
But before we talk about all the technical stuff and features that you should compare before finalizing a good air purifier for your home or office, you should consider the below things before even deciding to buy an air purifier.
Before you plan to buy an air purifier, try some simple steps to reduce indoor air pollutants, including:
- Vacuum often and thoroughly with a vacuum cleaner
- Never smoke indoors (we would advise quitting smoking completely)
- Maintain your air conditioners and clean ac filters regularly
- Minimize the use of candles, air fresheners, and incense sticks
- Use indoor air purifying plants
- Use kitchen chimneys while cooking. Use exhaust fans in kitchen, bath, and laundry areas
- Don’t store chemicals, solvents, glues, or pesticides near your living spaces
- Frequently clean your AC filter
- Keep doors and windows closed when the level of air pollution is very severe outside
Why Do You Need an Air Purifier?
If you are living in a city or area with high levels of air pollution than you should definitely consider buying an Air purifier. Below we have listed some major advantages of using an air purifier.
Air Purifiers –
- Ensure clean air to breathe and keep your lungs healthy
- Remove harmful gases and odour
- Remove airborne seasonal allergens and allergens released by pets
- Remove smoke and dust particles
- Remove up to 99 percent of airborne bacteria and viruses
- Stop sickness and germs from spreading
- Reduce the complications and problems faced by people with respiratory diseases like Asthma
Convinced You Need One? Read This First
Always keep the following things in mind before you decide to buy an air purifier for your home:
- Air purifiers are meant for air purification of one room, don’t be under the impression that any air purifier will work for entire home
- Always measure the size of the room (preferably in square feet) in which you wish to use an air purifier
- Avoid air purifiers that release ozone. Air purifiers with ionizers and UV light typically release ozone which has adverse health effects
- All air purifiers need replacement of filters at regular intervals
- Apart from the initial cost, the cost of replacing filters and electricity consumption should be kept in mind
- For optimum results, air purifiers should be kept running as long as the room is occupied
- Air purifiers with 3 stage filtration i.e. Pre-filter, HEPA filter, and activated carbon filter are ideal
- Air Purifiers are a must buy for people suffering from breathing problems or asthma or people who have a pet
How Do Indoor Air Purifiers Work?
Air purifiers may look and sound like a complex innovation but the working principle of air purifiers is quite simple. Air purifiers use a fan (something similar to an exhaust fan) that sucks the air in your room. This air is then passed through a series of filters that remove harmful airborne particles like dust, animal dander, pollen, and bacteria. The purified air is then circulated back into the room. This process keeps repeating itself to give you clean and fresh air.
Air Purifier Buying Guide – How to Compare Air Purifiers to Find the Best?
Buying an air purifier is complicated. Unlike most electrical appliances, there are no industry standards in place in India for rating air purifiers. Several brands like Philips, Honeywell, Blue Star, Livpure, Dyson, Mi, LG, Kent, Samsung, Panasonic and more, are offering their range of air purifiers in India. The continuously rising demand for air purifiers has resulted in aggressive marketing and launch of hundreds of models of air purifiers.
Air purifiers in India start from anywhere between Rs 5,000 and can go up to Rs 1 lakh. Apart from the budget there are several other factors that you should consider before buying an air purifier. This buying guide will help you choose the best air purifier in India.
Type of Filter
The effectiveness of an air purifier largely depends on the quality and type of filter. No single filter can remove air particles, gases and bacteria. Therefore scientists have designed specific filters to remove different contaminants of air. The most commonly used filter type is HEPA (High-Efficiency Particulate Air). It can remove 99.9% ultra-fine particles as small as up to 0.3 microns (approximately 100 times smaller than PM2.5). HEPA filters are the most effective and are therefore widely used in all popular air purifiers.
HEPA filters cannot remove the odour and gases like formaldehyde, cooking odour etc. You will have to use an air purifier with an activated carbon filter along with the regular HEPA filter to remove smoke, gas and chemical odours.
Most air purifiers also use a washable pre-filter that captures dust and large particles like animal hair. Pre-filter increases the life of HEPA and Activated Carbon filters.
Pre-filter, HEPA filter and Activated Carbon filters can’t kill microorganisms like bacteria and viruses, but some air purifiers have filters that come with antibacterial coating. UV light is also effective in killing microorganisms but they are believed to produce ozone which is not good for health.
Bottom Line: Air purifiers with multi-stage filtration are the best. Look for air purifiers with pre-filter, HEPA filter and Activated Carbon filter.
Clean Air Delivery Rate (CADR)
CADR (Clean Air Delivery Rate) tells you about how large area an air purifier can clean effectively. Ideally, higher the better but there are no regulations or standards to govern the air purifier market in India and therefore some manufacturers overstate maximum coverage area that may not be 100% accurate.
Typically measured in cubic meter per hour (m3/hr) or cubic feet per minute (cfm), CADR tells you how much air can be filtered for different contaminants like dust, smoke, and pollen.
If you are buying an air purifier for a large room then you should look for higher CADR ratings to make sure the air purifier is effective.
|Air Purifier Sizing for Particle Removal|
|Room area (square feet)||100||200||300||400||500||600|
|Minimum CADR (m3/hr) – 9 feet ceiling||102||205||309||410||515||620|
|Minimum CADR (m3/hr) – 10 feet ceiling||112||224||336||448||560||672|
|The CADRs are calculated based on a 9 and 10 feet ceiling. If you have higher ceilings, you may want to select a portable air purifier with a higher CADR.|
Bottom Line: Make sure that the Clean Air Delivery Rate of the air purifier is equal to or greater than the area of your room.
Air Change Per Hour (ACH)
While most air purifier brands boast about the CADR and coverage in square feet, they tend to hide ACH rating. ACH is the most perfect measure of the effectiveness of any air purifier and you should always find this out before buying an air purifier.
The ACH (Air Change per Hour) tells you exactly how often the air purifier filters the air of its claimed coverage area in one hour. If an air purifier that has 4 ACH, it means that the air in the room will be filtered 4 times in an hour or every fifteen minutes.
ACH rating is important because the air keeps getting polluted regularly and the air purifier needs to continuously clean the air. Keeping in mind the pollution levels in most Indian cities, look for an air purifier that offers ACH rating of at least 4.
As revealed above, most brands tend to hide the ACH rating while showcasing an inflated CADR and coverage area. But it does not make any sense at all, because if they are mentioning high coverage area but if the ACH is just 1 or 2, then it will be ineffective.
But how do you find the ACH rating if the same is not mentioned in the product specification? Worry not, because it is very easy to find using a simple formula. Read how to find ACH rating of an air purifier.
Bottom Line: Look for an air purifier that offers ACH rating of at least 4 for your room size.
The size of the room where you plan to use the air purifier should always be kept in mind before choosing an air purifier. Small rooms will need smaller air purifiers with smaller CADR and vice versa. For best performance, the best way is to go for an air purifier that is designed to cover an area that is 20-30% more than your room size.
Bottom Line: Look for an air purifier that covers 20-30% more area than your room size at an ACH rating of 4 or more.
Apart from the initial cost, the cost of replacement filters and their life should always be checked. Filters can cost anywhere between Rs 1,500 to Rs 5,000 with a lifespan of three months to a year. Apart from the cost of filters you should also check about the availability of filters because the biggest complaint that we came across online was the problems faced by users in finding the replacement filters.
Bottom Line: Replacement filters should be easily available, best if available online, and should not be too costly.
Considering electricity costs, try to hunt for an air purifier with energy star ratings. Most good air purifiers in India consume around 50-60 W power. Mi Air Purifier 2S has the lowest power consumption of 29 W only.
Bottom Line: If you are confused between two models that have same features and price but the power consumption of one is higher than the other then you should ideally choose the one with lower power consumption.
Noise level is important, especially if you are planning to use the air purifier in your bedroom or office. All air purifiers will make more noise when the fan is running at maximum speed.
You can do two things to avoid getting irritated by the noise, one is obviously to go for an air purifier that makes little noise even at top speed and the other is to pick a larger air purifier and run it on lower speed. The later solution will ensure both effectiveness and quietness.
Most air purifiers nowadays come with sleep mode that lowers the fan speed and noise.
Bottom Line: Ideally, noise level should be around 50 decibels when the fan is running at the top speed. Stay away from air purifiers with noise level above 75 decibels.
Filter Change/Clean Indicator
If the filters are congested then the air purifier will become inefficient. Some air purifiers feature filter change or filter clean indicators to inform when the filters need to be cleaned or replaced.
Most home air purifiers are designed to be easily portable so they can be easily moved from one room to the other. Carrying handle makes it easy to hold and carry the air purifier. Make sure the air purifier has carrying handle or in-built grip for easy portability.
Variable and Auto Speed
Never buy air purifiers that run on single speed. All good air purifiers provide you an option to change the speed as per your requirement. You can lower the speed during night for quieter operation and increase when you are playing with your pet.
Air purifiers with auto speed use dirt and/or light sensors to automatically adjust the speed.
Bottom Line: Always look for variable speed and auto mode air purifiers.
Air Quality Display
Air purifiers that come with a digital air quality display give you the level of particulate matter in air inside your room. The display also gives you a clear idea of effectiveness of the air purifier and keeps track of how clean your air is. Apart from the air quality, some models also display the temperature and humidity levels. Though the display does not have any effect on the effectiveness of the purifier but it definitely keeps you better informed and enhances the look and feel of the machine.
Bottom Line: Air quality display keeps you in control and better informed about the air in your room.
Remote or App Control
Though air purifiers are meant to run unattended without you having to make any frequent changes in settings, remote control provides you with a little extra convenience to change the settings lying on the couch or bed.
Smart air purifiers or Wi-Fi enabled air purifiers, like Mi Air Purifier 2S, let you monitor the operation and control the settings from an app.
Bottom Line: Features like remote control or mobile app are good additional features but do not fall in the trap of marketing gimmicks because a good air purifier is meant to quickly and effectively clean the air. Never compromise on the efficiency for these fancy features.
Pre-filter in air purifiers are just like the filters used in your Air Conditioners. Air purifiers that come with a washable and reusable pre-filter are quite good as they increase the life of HEPA and Activated carbon filters by collecting large particles. This reduces the overall costs. Air purifiers with washable pre-filter are great for people with pets or people living near under construction building.
Bottom Line: Air purifiers with washable pre-filter are good because they increase the life of HEPA filter and carbon filter,which reduces the cost of maintenance.
With all the above information in mind you are now ready to find the best air purifier for your home.

Mi Air Purifier 2S – Review
Mi has now become a household brand, all thanks to it’s range of highly popular and very affordable range of smartphones and LED TVs.
Mi is known to disrupt the market and set new standards in every product segment that it offers. And that is so true for the topic of this discussion, the air purifiers.
If you are looking for a new air purifier then chances are you must have already heard of Mi Air Purifier 2S because of it’s popularity and positive ratings.
Here we will tell you why buying Mi Air Purifier 2S makes sense.
Mi Air Purifier 2S features an ultra-modern and compact tower-structure design. Over 900 intake holes in front and sides maximize the air intake and improve the filtration capacity. Poor quality air in your room is sucked through the tiny intake holes by a high quality fan mounted on the top. This air then passes through a triple layer filter which removes all the air pollutants. Pollutant free air is re-circulated in your room from the top.
The striking OLED display at front displays the real time air quality inside your room. Apart from the PM 2.5 levels, the display also shows the temperature and humidity levels. The display not only lends a sophisticated look but is also provides you with very useful data about the quality of air and effectiveness of your air purifier.
The technology behind this live air quality data is a laser particle sensor on the top that senses the particles as small as 0.3 μm and displays the level on the OLED screen.
The highly compact design and light weight of just 4.5 kgs makes Mi Air Purifier 2S highly portable and you can shift it from one room to another quite effortlessly. It does not feature any handle or grip for, though not much required but a handle or grip would reduce the chances of accidental slip during shifting. Detachable power cable makes storing the unit easy, when not in use.
The filter compartment is given at the bottom and you can easily open the filter cover given at the back. Removing or replacing the filter is very easy. The inside of the cover features complete instructions on how to remove the filter and clean the dust sensor.
Mi Air Purifier 2S comes with a 3 layer filter, the outer layer removes large airborne particles such as dust and hair. The middle layer removes micron-sized particles and harmful bacteria. The inner layer, made of high quality activated carbon, effectively removes bad odour, formaldehyde and other harmful substances.
Talking about the technical specifications, this air purifier offers a CADR of 310m³/hr and claims to be effective for a coverage area of up to 400 sq. ft.
The company claims it can purify the air inside a room in 10 minutes.
Let’s see if that’s true or just a marketing gimmick.
This claim is based on the results according to Guangzhou (China) Industrial Microbiology Testing Centre’s CADR test report. The test was conducted in approximately 226 sq. ft. room, with a ceiling of 7.87 feet.
Ceiling size of 7.87 feet? They must be kidding.
So how do you find the actual effectiveness of Mi Air Purifier 2S? As detailed in our air purifier buying guide, the correct way to find the effectiveness of an air purifier is to look at it’s ACH rating.
Let’s find out the filtration capacity of Mi Air Purifier 2S. But before we do that we would like to reiterate that you should always look for an air purifier with minimum ACH rating of 4, this is even more important for people living in cities like Delhi (that have high level of air pollution).
Below table lists the ACH rating for different room sizes.
|Mi Air Purifier 2S Filtration Capacity|
|Room area in square feet (ceiling height is assumed as 9 feet)||100||200||300||400|
As you can see in the above table, this air purifier offers ACH rating of 4 up to a room size of 300 sq. ft. If you have a high ceiling of let’s say 10 feet than the effective coverage area would be 270 sq. ft.
So the claim that this air purifier can cover up to 400 sq. ft. area is more of a marketing gimmick.
Taking the lead from it’s range of smart phones and smart LED TVs, Mi has built a lot of smartness in the air purifier as well.
Mi Air Purifier 2S is IOT (Internet of Things) enabled and can be monitored and controlled remotely with the Mi Home App. The air purifier connects to your home Wi-Fi and sends all the data in real time to the app. You can check the air quality, temperature and humidity, adjust the fan speed and set a timer to power on the purifier. The App also automatically let’s you know when it’s time to replace the filter.
It also works with voice assistants like Google Home and Amazon Alexa. That means you can control this air purifier with your voice.
Another smart feature of Mi Air Purifier 2S is it’s ability to automatically adjust the brightness of OLED display according to the light in your room. The OLED display would be very bright during day time and would automatically reduce it’s brightness when you switch off the lights. You can also switch the display off by tapping on the display button given on the back.
Noise & Energy Efficiency
In sleep mode, the sound produced is hardly noticeable, but the noise at highest fan speed can go up to 70 dB (slightly more than the noise of your AC). The purifier consumes maximum power of only 29W and only 4.8W power in normal mode, which is very efficient.
The filter lasts for 3-6 months depending on the quality of air. The Mi Home App will automatically alert you when the filters needs to be replaced.
The filter is very easy to remove and replace and is easily available online at Rs. 2,199.
The best thing about the filters of this air purifier is you won’t find any inferior quality duplicate filters as each filter comes with a unique RFID tag. The purifier will only work if the filter is genuine.
This air purifier offers three different modes like Auto Mode, Sleep Mode and Favourite Mode. In auto mode, the air purifier automatically adjusts the speed of the fan according to the air quality. In sleep mode the fan runs at the lowest speed to avoid any noise and brightness of the display is reduced.
|Displays real time air quality, temperature and humidity||Not that effective for rooms over 300 sq. ft.|
|Ideal for rooms up to 300 sq. ft.||The air quality reading can be incorrect sometimes|
|Can be monitored and controlled remotely with the Mi Home App||No washable pre-filter|
|3 Layer filter with RFID tag|

Philips 3000 Series AC3256/20 Air Purifier – Review
If you are looking for a high performance air purifier that provides effective coverage for large rooms or if you or any of your family members suffer from respiratory diseases then Philips 3000 Series AC3256/20 is a good choice.
This air purifier from Philips not only covers a large area but also comes with advanced features and 2 years warranty.
Philips 3000 Series AC3256/20 features the popular tower design with a hollow ring in the top middle part. The powerful fan sucks the polluted air into the three large size air intakes provided on the sides and bottom.
This polluted air passes through a high performance multi-layer NanoProtect filter which removes all the ultra fine particles as small as 0.02 microns, bacteria, viruses, odours and harmful gases.
The purifier weighs around 10 kgs, the extra weight can be attributed to high performance fan that offers larger area coverage. Keeping the little higher weight in mind, Philips has provided a big handle at the top for easily moving the air purifier from one room to the other. However, we feel wheels at the bottom would have made it much more portable.
The top part features the sensor touch UI with big numerical display that shows the real-time indoor air quality in form of a numerical PM 2.5 value. Apart from the numerical value, 4-step color ring feedback also provides the feedback on indoor air quality. The blue color ring means good air quality, blue violet means fair, red purple is unhealthy and red is very unhealthy.
The sensor touch UI features controls for power on/off, child lock, light on/off, fan speed/auto mode/allergen mode, 24 hour timer and reset.
The front panel houses the 3 filters and can be easily removed when you need to clean or replace the filters.
Philips 3000 Series AC3256/20 comes with extra thick NanoProtect HEPA filter, activated carbon filter and a pre-filter that provides superior purification and lifetime against airborne particles.
Pre Filter removes all the large particles like dust, pollen, dust mites, and hair etc. Pre-filter is washable.
Activated Carbon Filter removes bad odours, harmful gases and TVOCs (Total Volatile Organic Compounds).
HEPA filter removes ultra fine particles up to 0.02 micron (100 times smaller than PM 2.5) like H1N1, PM 2.5, dust mites, pet dander & other bacteria, viruses. It removes 99.97% common airborne allergens and 99.9% bacteria.
The filters have a long lifetime and would need replacement every year or so.
This Philips air purifier offers high Clean Air Delivery (CADR) rate of 393 m3/hr, which makes it effective in large rooms.
The company claims that this air purifier is effective in coverage area ranging up to 1027 sq. ft.
Let’s find out the effectiveness of their claims.
|Philips 3000 Series AC3256/20 Air Purifier Filtration Capacity|
|Room area in square feet (ceiling height is assumed as 9 feet)||200||300||400||1000|
As you can see in the above table, this air purifier offers ACH rating of 4 up to a room size of 400 sq. ft. If you have a high ceiling of let’s say 10 feet than the effective coverage area would be 350 sq. ft. If you are living in high air pollution area and are suffering from respiratory diseases then it will be most effective up to 400 sq. ft.
However, you can use this air purifier for larger coverage areas provided you are living in an area that does not have severe air pollution.
With this high performance air purifier from Philips you will always feel in complete control with it’s advanced particle sensor that always gives you very close to actual level of PM 2.5 in your room. The display shows the numerical value for the PM2.5 level and the 4-step color ring also provides instant feedback on the indoor air quality.
Unlike the other air purifiers available in market, this air purifier uses a professional-grade sensor. Termed as Philips AeraSense technology, this air purifier is highly effective in sensing even the smallest change in indoor air quality. When in auto mode, the air purifier automatically adjusts the fan speed when it detects any change in the air quality.
Allergen Mode is a specially designed feature that effectively removes all the common airborne allergens. This mode is very useful for people suffering from respiratory diseases like Asthma, Chronic Cough etc.
Apart from the Auto Mode and the Allergen Mode, this air purifier offers five different levels of fan speed settings which is quite good. You can also set the timer from 1 hour to 24 hours for automatic shut off.
Noise & Energy Efficiency
Given the powerful performance and wider coverage one would think that this air purifier would be quite noisy. This is where the Philips technology and research comes into play.
We are quite surprised by the ultra silent performance of this purifier. Under sleep mode the noise (33 dB) is hardly noticeable and even at highest speed the maximum noise level is around 64 dB.
The air purifier consumes less than 0.5 W when in stand-by mode and during operation the power consumption varies between 11 W to 60 W, depending upon the operation mode and fan speed.
The filters are very easy to remove, clean and replace. The activated carbon filter costs around Rs. 2,000 and HEPA filter costs around Rs. 3,300 and are easily available on Amazon.in. The use of pre-filter increases the life of HEPA and Activated Carbon filter and the two would easily last for a year or more.
The air purifier automatically alerts you when it is the time to replace the filter or clean the pre-filter. The air purifier would stop functioning if the filter is not replaced in due time. This makes sure your air purifier is always working effectively and efficiently.
This air purifier is tested and certified by leading organizations like AHAM, ECARF (for allergy-friendly) and Airmid (for removal of H1N1 virus).
|Very easy to operate, auto mode requires almost no changes||Wheels at the bottom for easy movement would have been a plus|
|Beautiful and sturdy looks||Remote control or App control is missing|
|5 different fan speed levels|
|Auto mode & Special Allergen Mode|
|Child lock & 24 hour digital timer|
|Option to turn on/off the LED ring light and display light|
|Good performance and low noise level|
|Protection from H1N1 virus|
|2 Years Warranty|
|Washable Pre-filter increase the life of HEPA filter|
|Alert for pre-filter wash and filter change|
Bottom Line: This high performance air purifier gives you purified air that is 99.97% bacteria and airborne particles free making the air inside your home safer and healthier. 2 Years warranty keeps you covered against any possible malfunctions and breakdowns. The price is a little high but if you are looking to keep your family safe from allergies and dust then this is the best air purifier for you. Philips AC3256/20 is also a great buy for people who are prone to allergies or suffering from respiratory diseases like Asthma.
And now we come to the end of this long and detailed post on finding the best air purifier for your home in India.
Apart from air purifiers you can also use special indoor plants that are very effective in purifying the indoor air. These air purifying plants absorb gases through their pores on the surface of their leaves and roots. Some of these plants include Peace Lily, Weeping Fig, Snake Plant, Boston Fern, Aloe Vera, Spider Plant etc.
But each one of us must understand that using air purifiers is not the permanent solution or your safeguard against this worsening level of air pollution. The fact that India has as many as 14 out of the top 20 polluting cities in the World is a cause for serious concern and a matter of shame for all of us.
Should we simply put the blame on the Government? Along with the Governments, rapid industrialization and urbanization, we ourselves are to be equally blamed for all this mess.
And nothing will change, until we all take a pledge to stop contributing to this menace of ever growing air pollution.
The time is running out and we must act now to give better air to our future generations. We all should:
- Stop using diesel vehicles
- Start Car pooling or use public transport
- Plant and nurture as many trees as possible
- Do not burn waste or crop residue
- Use clean fuels like CNG, PNG etc.
- Stop using Diesel Generators
Air purifiers are only effective indoors but you can not always stay inside. If you are living in a city that has a high level of air pollution then you should also wear the protective N95 masks whenever you step out.
