for December 2022

When it comes to indoor air quality, an air filter is a staple. From electric fans to air conditioners, air purifiers to humidifiers, keeping your home's air clean and fresh is a top priority. Different types of air filters, or air filtration devices, can help manage different things, like allergens, dust mites, dander, smoke, mold, odors and more.

An air filter works by trapping particles, like dust, bacteria, pet dander, pollen, mold, smoke, and odors, which are suspended in the air. Depending on the type of air filter, it can capture particles as small as 0.3 microns (perfect for getting rid of pollen) to 100 microns (for removing larger particles like dust).

Many air filters, including air purifiers and humidifiers, need to be replaced at least twice a year. To keep your air filters working their best, it's important to replace them regularly. Even replacing air filters every year can add up to a lot of savings over time.

Our lab evaluates air filters for performance, ease of use, energy efficiency and noise level. We score the noise level, ease of installation and cleaning, ease of maintenance, filter life, filter type, and output capacity
