Best Large Room Air Purifier Buying Guide

Doctors suggest that indoor air is 20 to 30 times more polluted than the air outdoors. The suspended particles are more concentrated in the air indoors. These are majorly caused by cooking fumes, smoke, pet furs, chemicals from paint, nail paints, deodorants, mites, etc.

Children and old people are more likely to get affected by these particles. Clean air quality in rooms provided by air purifiers prevents chronic diseases like Asthma, Lung Cancer, and Bronchitis. Keep these attributes in mind when buying the best large room air purifier.

Room Size

The type of air purifiers you bring home would largely depend on your room size. Air purifiers exchange air every 4-5 times in an hour; however, using a small purifier in a sufficiently big space may reduce its efficiency and gives compromised air quality.

Carefully consider which place to put your purifier in and what is the output desired, accordingly purchase one that closely matches your needs. We are providing standard room sizes for you to select air purifiers with different cleaning capacities. Small room size is 155 square feet, medium rooms are 300 square feet while large room is more than 500 square feet.

CADR

CADR is Clean Air Delivery Rate, this measures how effectively an air purifier cleans the air. A higher CADR number indicates better performance of the air purifier. For larger operating space, one should be looking for higher CADR scores of a purifier. The CADR is stated separately for dust, pollen, and smoke.

Filter Types

Air purifiers use different kinds of filters depending on their working mechanism, often multiple filters are packaged in one unit/cartridge to offer various levels of filtering in one product. Most common filter types are:

HEPA: HEPA is short for High-Efficiency Particulate Air. These filters trap 99.7% of air pollutants up to 0.3 microns in size. Almost all air purifiers use different grades of HEPA filters. HEPA filters are technologically advanced, approved by air pollution regulating bodies. HEPA are mechanical filters. These push air through a very fine mesh to collect dust, mites, pet dander, etc.

Activated Carbon Filters: Activated carbon or charcoal filters trap gases, smoke, odor, etc. These are processed charcoal that forms very fine pores to capture minute particles of smoke and chemicals. Activated carbon traps pollutants at its outer surface, thus preventing it from penetrating within. Charcoal filters are usually washable and can be cleaned at home.

UV-C Filters: These filters use short wave UV light at high intensity to deactivate the pathogens or germs that cause diseases. Thus UV-C filter also acts as a sanitizing layer. It is mostly added after activated carbon and HEPA filters.

Ionizers: Many air filters also ionize the air, this is the last or most intense purification process. Ionizers release anions or negatively charged ions that bind with positively charged chemicals in the air, thus neutralizing the air and making it 99% pollutant free.

Replacement Cost of Filters

Some innovative and next-generation air purifiers have filters that can be cleaned and reused, all popular air purifiers still need filter replacement every 6 months or yearly. Consider the replacement cost of filters before you select an air purifier. Compromising with filter replacement may reduce the efficiency of the purifier and resultantly the air quality that you breathe in.
