Which Type of Air Purifier Should You Get?

If you’re concerned about indoor air quality, then you’ve likely considered purchasing an air purifier. Finding the ideal one, however, is no simple task. Many different brands and models are available, some of which are intended for particular uses.

Here, we compare and contrast the five most popular filters:

HEPA Filter

A High-Efficiency Particulate Air filter (HEPA) is a free-standing model with a cartridge that captures particles as air passes through it. It will accomplish the desired result, which is to lessen the dust and pet dander present in your home. Make sure you complete your research. The HEPA rating gets bandied about as a marketing ploy. Look for products labeled “True HEPA” to ensure you get the best filtering technology. Genuine HEPA filters meet standards the U.S. Dept. of Energy set to capture 99.97% of particles as small as 0.3 microns. You’ll come across terms including “HEPA-Like” and “HEPA-Type.” There is no minimum standard set for these products.

Air Ionizer

Unlike the HEPA filter, an air ionizer does not capture airborne particles with a filter. Instead, it releases negatively charged particles like dust, allergies, pathogens, and smoke that stick to positively charged particles. After being neutralized, the particles precipitate on the furniture and floor. This machine might be for you if you don't like cleaning.

Electrostatic Filter

Like the air ionizer, an electrostatic filter charges particles to remove them from the air. Instead of an ionizer, an electrostatic filter traps the particles inside the device, reducing the need for frequent use of a feather duster.

Activated Carbon Filter

Another device for eliminating odors uses chemical absorption, such as an activated carbon filter. The device has a bed of powdered charcoal that captures contaminants, such as those from VOCs and common household chemicals, and only leaves behind clean air.

UV Light

A lamp, typically attached to your HVAC system, emits germicidal UV rays that render contaminants inert as they move through the air. Additionally, this is a strong deterrent against mold, which thrives in damp, dark areas like your ducts.
