What to Look for When Buying an Air Purifier

With so many models on the market, there's definiltey an air purifier that is right for your individual needs. The challenge is often not finding options, but narrowing down to a single product from a few that are suitable.

Earlier in the buying process? We've included some considerations to include as you find an air purifier.

HEPA Filtration

Most air purifiers use paper filters with a rating which indicates how effective they are at removing airborne particles. Just about all air purifiers today use a filter which is HEPA or H13 rated. Some manufacturers use integrated or separate charcoal filters.

HEPA filters remove 99.99% of particles .3 microns in size or larger, and 99.997% of particles .1 microns or larger. One micron is 1/1000 mm, or approximately 1/25,000 of an inch. That size is likely still hard to imaging, but this might help: to be seen by the naked eye, a particle would need to be around 25 microns in size.

HEPA filters are the most popular method for air purification although other technologies are sometimes employed in combination or on their own. 

Activated Carbon Filtration

Many air purifiers have activated carbon filtration integrated into their main filters. Some also have a separate carbon filter within the unit. Charcoal filters deodorize the air, removing smells before returning clean air to the room.

Electrostatic Filtration

As opposed to catching contaminants and pollutants in filter media, electrostatic filtration takes a different approach. When particles are pulled into the air purifer they are electrosticallly charged. Then, as they move past plates in the unit, the particles become drawn to them. 

Electrostatic plates are generally removable and reusable.

Ultraviolet Light

UV light is another option that some air purifiers employ. Purifiying air with UV light is often cited as a way to remove mold spores and even viruses from the air.


Air purifiers using ionization take a different approach to cleaning the air altogether. Ionization produces charged ions inside the air purifier. Particulates in the air are negatively charged, creating an attraction between the two.

The result is that the particles are heavier, meaning they fall to the ground (or another surface) as opposed to traveling in the air.
