Air Purifier Buying Guide India

1.What is an Air Purifier?

An air purifier is a stand-alone device that has either 1 or 2 fans and multiple filters. Since most pollutants are a form of suspended particulates, these purifiers by making proper use of the advanced filtration technique, separate the pollutants by forcing the air through those filters, thus providing you a clean and breathable air inside the house or office.

2.How Much Power Does an Air Purifier Consume?

Most of the current gen air purifiers consume very less electricity, normally ranging from 15 to 60 watts, depending on the capacity used by filtration and advanced features.

3.Do You Really Need to Buy an Air Purifier? Why?

Air pollution is one of the biggest nightmares of our present generation as it causes various respiratory related diseases like Asthma, COPD (Chronic Obstructive Pulmonary Disorder) and Lung Cancer.

Since we’re living in the polluted cities, there are more chances of us getting prone to these diseases. Not just air filtration, these air purifiers also remove common allergens like pollen, dust, pet hair, bad odor etc

Here is a list of the most polluted cities in India according to a study held by WHO (World Health Organization) in 2016.

Delhi is the number 1 most polluted city in India. It is also the 2nd most polluted city in the world.

CityPM2.5 (µg/m3)PM10 (µg/m3)
Patna (Bihar)149164
Gwalior (M.P)144329
Raipur (Chattisgarh)134305
Ahmedabad (Gujrat)10067
Firozabad (U.P)96218.5
Amritsar (Punjab)92210
Kanpur (U.P)88201.5
Agra (U.P)88200
Ludhiana (Punjab)86195.5

So, if you’re living any of these cities, you’re already breathing all the bacteria and viruses through the air and you definitely need to consider buying an air purifier. If you’re from the other cities, you can prevent these diseases in the future by getting one for your home/office.

How Air Purifiers Work?

4.How to Choose an Air Purifier?

Generally, all the air purifiers are rated with a coverage area in square feet. So, it is very simple to pick one. Just, measure your room or office or entire house for which you’re planning to install the purifier and select the one that is rated 100 sq.ft or higher.

For example, if your room is 300 sq.ft, then you should choose the air purifier that covers up to 400 sq.ft, for best results.

Besides the coverage area, the other things you should consider are the features and brand, which we’ve covered later in this guide.

5.How Many Air Purifiers Do You Need?

The count depends on the place where you need some clean and breathable air. Most people pick their bedroom because that is where they sleep and spend most of their time in the house (nearly 8 hours).

For an ideal bedroom, 1 air purifier is more than enough to completely clean the air inside it. If you’ve multiple bedrooms/rooms in your house, then you can either move it to the 2nd room after the air in the 1st room is purified and so on…

However, if you’ve some budget, then you can install separate purifiers for each room.

How to Find Out ‘Area Coverage’ for an Air Purifier?

Selecting an Air Purifier without knowing the size of your room is definitely not a wise decision. Why because, an air purifier with coverage of up to 250 sq.ft might not give you the desired results if you keep it in a room with a size of 500 sq.ft.

We’ll now see the steps that will help us figure out the square footage of a desired area.

Use this square footage calculator, if you’ve any confusions.

A.Single Room

Let us assume, you wanted to place the purifier in your bedroom. The steps to find the square footage for a single room is pretty easy.

Just take a measuring tape and measure the two perpendicular walls.

Our Choice for a Small Room: Eureka Forbes Aeroguard Mist 56-watt

B.Multiple Connected Rooms

In such cases, you’ll have to measure the length and width of each room separately and then club the results.

For example, if you’ve two connecting rooms A & B, and A measures 150 sq.ft, while B is measured at 50 sq.ft, then the total square footage would be 150 + 50 = 200 sq.ft.

Our Choice for Multiple Rooms: Philips 2000 Series AeraSense AC2887

C.Entire House or Office

If you’re planning to get an air purifier for your office or entire house, then you can easily know its size by looking at the paperwork that you got while purchasing the space.

In case if you don’t have the paperwork handy, then simple step outside of your home/office and measure the length & width of your walls from the outside.

And, simply multiply the resulting number with the number of levels your house has.

Say for example, the outer square footage of your house/office is measured at 1200 sq.ft and you’ve two levels, then the total square footage would be 1200 x 2 = 2400 sq.ft.

Our Choice: Blueair 650E Digital Hepasilent Air Purifier

That’s all friends! Now, since you know the area/size of your room/house/office, you should find the right air purifier with the desired space coverage.

6.What Filters to Choose from?

Air Filters Purification Process

The first thing you should look in an air purifier is if it has the HEPA filter aka high-efficiency particulate air filter.

Different Types of Air Filters in Air Purifiers

There are 6 common types of air filter technologies available in the market.

  1. HEPA
  2. Activated Carbon
  3. Ultraviolet Light
  4. Ionic Filter
  5. Pre-Filter
  6. Ozone

#1.HEPA Technology

HEPA stands for High-Efficiency Particulate Arrestor technology, which has the capacity to trap up to 99.97% of all airborne particles as small as 0.3 microns and up to 95% of minute particles as small as 0.1 microns.

It removes PM 2.5 particles and even cigarette smell in order to provide pure breathable air inside your home, office or car.

Benefits of HEPA Air Filter

  • Removes dust, pollen and other allergens
  • Removes most bacteria with 99.97% efficiency
  • The solid particles are not released into the air again

#2.Activated Carbon Technology

The Activated Carbon filter comes with small spongy pores which filters the pollutants as they pass through it. It is very effective in removing smoke, chemicals, false smell and even gases, thus making the air more purer.

Activate Carbon filters are mostly used in conjunction with HEPA filter or Ion Filter and not alone.

Benefits of Activated Carbon Filter

  • Captures gases, chemical fumes, odor
  • Pollutants easily bonds with the carbon and get trapped

#3.Ultraviolet Light or UV Light Technology

Ultraviolet light destroys bacteria and other pathogens by making use of the electromagnetic radiation. The UV light filters, instead of filtration, simply kills the particles by breaking the molecular bonds in their DNA.

It is highly advised to get an air purifier with UV light filter, HEPA and activated carbon filter to remove a wider range of air contaminants.

Benefits of UV Light Filter

  • Prevents illness and air contaminant diseases
  • Instead of filtering, they just destroy the micro-organisms from the root

#4.Ionic Filter Technology

Ionizer or Ion filter is made of a -ve ion generator that sends -ve ions to attract +ve dust and allergens that are present in the air.

So, the particles in the air fall down due to heavy load, thus making the air clear of smoke and foul smell.

Note: An Ion Filter doesn’t help if you’ve dust and pollen. So, you might have to consider an air purifier with HEPA, Activated Carbon and Ionizer.

Benefits of Ion Air Filter

  • Works silently because it has no motor or fan
  • Eradicates ultra-fine particles as small as 0.01 microns
  • Cleans the smoke, viruses and bacteria off the air


The purpose of the pre-filter is to capture the largest particles such as hair fur, dust and some pollen before they enter the main filters such as HEPA filter.

This is also the first line of defense and it helps in prolonging the lifespan of the main filter.

Most of the pre-filters last a lifetime and are even washable & reusable.

In some air purifiers, the pre-filter comes combined with a carbon filter.

Benefits of Pre-filter

  • Catches large particles like hair fur, dust and some pollen
  • Decreases the load on main filter & improves its lifespan

#6.Ozone Purification Technology

Air purifiers with Ozone filter produces O3 or Ozone gas, which as stated by the health professionals, may increase asthma symptoms.

Moreover, it does not removes dust and pollen.

So, it is advised not to use Ozone air purifiers and even we don’t recommend them.

7.Which is the Best Placement for Air Purifier?

For maximum efficacy, you should place the purifier at the corner of the room without any table or almora or wall blocking it from circulating the air. When you give it enough room with doors and windows closed, you’ll experience the best quality air.

8.What is the Cost of Filters? How Frequently Should I Change Them?

The filters should be replaced periodically and the cost of the filters depend on the type of air purifier you’re using.

For example, a HEPA filter lasts for about 1 year, while the activated carbob filter lasts 6 months and the pre-filter lasts for only 3 months.

It is hence advised to inquire about the expected life of the filters and their cost before making a purchase. Normally, you can find this information in the product specifications.

9.What Kind of Features You’ll Need?

Most of the air purifiers in the market comes with variety of useful features to enhance air cleaning and help the user save more on energy consumption. Here is a list of most common added features:

  • Remote Control: You can easily control the air purifier from a comfortable distance wirelessly.
  • Electronic/Touch Controls: Let you select the settings more accurately.
  • Multiple Fan Speeds
  • Programmable Timer: Automatic timer to turn on/off at certain times.
  • Filter Replacement Alerts: These indicator lights alert you when it is time to replace your filters.
  • Ionizer: Helps in capturing small and large particles and is said to boost your mood. But, it is not good when it comes to health. Stay away from this feature.
  • Air quality monitor: Automatically senses the pollution levels in your room and adjusts itself to optimal mode to remove the pollutants.
  • Germicidal Protection: Fight bacteria and viruses present in the air.
  • Carrying Handle: Finally, a handle can help in easy transferring of the air purifier from one room to another.

10.What are the Noise Levels of an Air Purifier?

Generally, most air purifiers come with decibel (dB) rating for different fan speeds. You can check them on the product specifications. Below is a comparison table that helps you get an idea of how much sound an air purifier makes based on its decibel rating (provided in the specs sheet).

Decibel (dB) RatingSounds by Indoor Appliances
0 dBMinimum threshold for hearing
10 dBNormal breathing sounds
20 dBRustling/Falling leaves
30 dBAverage whisper
40 dBLight rainfall
50 dBHeavy rainfall
60 dBBox fan
70 dBVacuum cleaner

11.The Pros and Cons

All the products come with both pros & cons and it is the same with the air purifiers. However, you’ll need to consider the ones that suit your requirement and fall under your budget.


  • They’re portable in size and weighs around 10 to 20 pounds.
  • Most lightweight air purifiers come with a handle to move it around the room, while the heavier models have wheels.
  • Most come with HEPA filter for capturing ultrafine particles
  • Consume less power
  • Converts polluted air into breathable clean air.


  • Portable models that use either ionizer technology or electrostatic-precipitator are said to produce a lung irritant known as ozone, which is a serious health concern and you should avoid air purifiers with ionizer for that reason. The others without ionizers are very helpful though.
  • Filters need to be replaced periodically.
  • Filters usually are very expensive and you should know the costs before making the purchase.
