How to Choose the Air Purifier for Home?

In this section of this article, we have mentioned some important factors that will help you to select the right one. You should consider the following qualities before buying Air Purifier for indoors:

Room Size

It is one of the most important factors that you should know when you focus on buying the new air purifier for you.

You should choose the air purifiers according to your room-size. The coverage area of air purifiers should be equal to or greater than the area of the room.

Philips 2000 series is ideal for 410 Sq ft.

You can install it in large bedrooms, living rooms, dining rooms, hotel rooms.

Choose the Right Filter Technology

High-Efficiency Particulate Arrestant filters are the most commonly used filters in the air purifiers. There are other kinds of filters, such as ion and ozone generators, anti-bacterial filter, activated carbon filter, etc.

The four most usually used methods are:

  • HEPA Filtration System
  • Ionic Filtration System
  • Photocatalytic Filtration System
  • Carbon Filtration

Depending upon the size of the particles, there are different ways of trapping the impurities such as diffusion, interception, impaction, or sieving.

You should check the type of filter. Pre-filters eliminate larger particles such as animal hair, dust, and other impurities.

HEPA filters are easy to clean. This HEPA filter removes toxic particles like dust, pollen, soil and cigarette smoke, other suspended particles, etc. For trap smallest particles in the air, 3 components are used by the HEPA filters. Therefore, HEPA filters are great option in the market. The top grade HEPA filters, HiSiv filter let enjoy the greatest levels of pure air.

The Activated carbon filters help to reduce the pet dander, airborne fungi, dust, and harmful chemicals. The carbon filter is capable of absorbing a large number of contaminants in best ways.

Ionic Air Purifiers work on an ionic filter. Ionizer emits a cloud of charged-ions that react with the dust particles. These air purifiers with ionizer can catch 0.01 microns sized particles.

Photocatalytic-Filters or photocatalyst filter use TiO2 (titanium dioxide) as a catalyst. It works on PCO (photocatalytic oxidation technology). When Ultraviolet light strikes it, the electrons (negatively charged ions) are released in the air. These negative ions react with water molecules present in the air and break them into hydroxyl radicals. These radicals attack more significant organic compounds.

The biggest drawback of these types of filters in air purifiers is that they produce a small amount of Ozone that itself is an air pollutant.

Ozone generators that are available as an air cleaner should be avoided. Their drawback is that inhalation of ozone is not suitable for health.


It is an electric device. It charges the ions for dumping smoke ashes and dust in best ways.

Auto Modes

It is necessary to save human efforts. Air purifiers come with inbuilt advanced air purification features like sleep mode, night mode, Bacteria and virus mode, HEPA Filter Change alarm, Allergen mode, etc. Some air purifiers can be linked with the Home app to enable IoT capabilities such as remote operation and monitoring.

Noise Level

The noise levels of the air purifiers depend upon the fan speed. Higher the rate of the fan speed, louder the device is.

Many of the air purifiers that come with a fan also have speed adjustment option. So, check whether they have that setting or not so that you can controlled the fans speed to reduce the level of noise.

ACH Ratings (Air change per hour)

It is another crucial factor to consider while purchasing an air purifier for your home. ACH stands for Air Change per Hour. ACH rating tells us how often can an air purifier exchange the air in the room. It is expressed in the multiples of ‘x,’ for example; 3x, 6x, etc.

Higher the number, more efficient the air purifiers is in purifying the air inside the room. Buy an air purifier with maximum air-exchange rates that will clean the air faster.

Power Consumption

It is another essential thing to consider while choosing an air purifier. Depending upon usage and brand. The high wattage purifier uses a lot of power.

Philips 1000-series uses just 50-watt. MI air purifier utilises 4.8 to 3.1 Watts.

Atlanta Gama Pure works on 43 watts.

If you are planning to use an air purifier for a longer-time, make sure to clean it regularly. It will cut down your electricity bill in the long-run.
