Buying Guide- Best Air Purifiers

Want to buy air purifier for your home but not able to decide how to buy Air purifier? You should go through our air purifier buying guide to understand different types of purifiers and things to keep in mind before buying an air purifier.

Air purifiers can be classified either based on purifying technology they are using or based on portability.

Types of Air Purifiers – As per Technology

There are essentially five types of purifying technologies. Please keep in mind that air purifiers will often employ more than one purifying technology because no technology is complete in itself.

Air Purifying TechnologyTarget PollutantMethod of Working
HEPA FilterParticlesCapture pollutants of almost all sizes
IonizerParticulateAttract particles by charging the particles and then attracting them with opposite charge
Ozone generatorGasesOxidize gases in the air
Plasma wave generatorGasesNeutralize gases by breaking chemical bonds between them
UV lampsMicrobesUV light neutralizes airborne germs by denaturing their DNA
Activated carbon( & other absorbents like activated alumina)Gases and OdorsAbsorb gas and organic pollutants

1. Basic and HEPA filters:

These are most common filters available in India today. HEPA air purifier remove cancer causing particles such as dust mites, pollens, cigarette smoke, animal skin etc. IT can remove particles of size of as small as 0.3 microns.

This works with help of filters. Therefore you will have to replace the filters every few months depending on your usage.

2. Ozone Generators:

Ozone air purifiers work by producing actual Ozone air by charging the oxygen in the air and charging it and converting it into Ozone. Exposure of Ozone can be harmful for asthama patients since Ozone is not good for health.

3. Activate Carbon Technology:

This filter works on principle that porous activated carbon with very high surface area can be used to remove particulate matter. The pores trap different types of compounds. It is usually used in addition to existing purifying technology. Also, it is very useful in case your existing purifier is not able to remove the smell in the air. Even these filters have a life span and have to replaced when its life ends.

4. UV technology:

It is a powerful way to destroy microorganisms. This technology is also used in water purifiers for the same purpose. Since it is helpful in removing microorganisms such as bacteria and viruses, it used in addition to existing filter technology to combat particulate matter int e air.

Also, this technology works by producing Ozone and destroying germs, purifier should be able to absorb / handle the produced Ozone because Ozone gas itself can be harmful of not regulated.

Therefore it is recommended to change Ozone lamp as per manufacturer’s recommended time frame. Typically, after a air is filtered by HEPA and other technologies like activated carbon, UV is applied in final stages of filtration.

5. Ionizer:

Ionizers produce charged particles or ions. The ions charge particulate matter and trap them. They are particularly effective in removing very small particles that HEPA or other filters are not able to filter. Therefore they are used in conjunction to filter technology

Types of Air Purifiers – As per Portability

1. Pedestal air purifiers:

These air purifier can be placed on floor surface and are heavier in weight.

Advantages of a Pedestal air purifier:

  • It is the most efficient type of purifier
  • It has higher CADR and ACH

Disadvantages of Pedestal air purifier:

  • It is typically heavier in weight.
  • It produces more noise
  • It takes more space in the room

Table-Top air purifier:

Also call portable air purifiers, these filters are the light-weight air purifiers and are pocket friendly

What to look for while buying air purifier?

1. CADR:

CADR stands for clean air delivery rate. It is a measure of speed of delivery of purified air by the purifier at its highest speed setting.

As a general rule, large room size requires higher CADR rating

The Environmental Protection Agency (EPA) has given these guidelines for minimum CADR ratings by room size:

Area (square feet)100200300400500600
Minimum CADR (cubic feet per minute)60130195260325390

2. Noise:

Air purifiers produce noise. There you have to be careful of the noise levels of the air purifier before purchasing.

You can typically choose air purifier with higher noise for living room, while bedroom should have purifier with lower levels     

Anything less than 20 db is excellent. 60 dB noise levels are very similar to noise made by AC.

3. Air Change Rate:

Also called ACH or Air change per hour, Air change rate is the number of times the entire air in the room is fully purified in an hour.

For example, ACH of 2 means that air is being purified every 30 minutes.

4. Anti- bacterial coating:

Presence of anti-bacterial coating in HEPA filters is an added benefit

5. Maintenance and electricity cost:

Apart from purchasing cost, Air purifiers use good amount of power. Higher power usually means more efficient purification, and more noise. Therefore you have to maintain a banlance between cost, effectiveness and usability.

Also, filters have to be replaced from time to time. Typical life of HEPA filters is 2000 hours. It means if you are using it for 10 hours per day, then filters will last for 200 days ( 6 to 7 months)
