Allergy Air Purifier Buying Advice

5 min read

Not every allergy air purifier is created equal. To begin your search for the allergy air purifier best suited for your needs, we advise considering technology, square footage, and warranty. Read on for allergy air purifier buying advice to get started.

Three Things to Consider When Buying Air Purifiers


1) Air Purifier Technology
There are three main allergy air purifier technologies: Ozone Generators, Electrostatic Air Purifiers, and High Efficiency Particulate Arresting (HEPA) Air Purifiers. In our research, we find the most effective allergy air purifier technology to be HEPA, capable of removing up to 99.97% of airborne particles, like pollen, dust, and other allergens. Ozone generators emit dangerous lung irritants and electrostatic air purifiers only remove up to 30% of airborne particles.

2) Air Purifier Square Footage
When purchasing air purifiers for allergies and other issues, consider the square footage of the space you want to treat. Every allergy air purifier is designed to cover a specified amount of space, so it is critical to invest in the appropriate unit for the room. For example, an allergy air purifier designed to cover a 300 sq. ft. area will not achieve optimal results if placed in a 750 sq. ft. room. To make certain your allergy air purifier will perform most effectively and efficiently, select a unit appropriate to the coverage area.

3) Air Purifier Warranty
While every allergy sufferer’s condition differs, and predicting how an allergy will develop is very difficult, you’ll want air purifiers that have a track record and a good warranty. The good news is that allergy air purifier warranties are continually improving. Recommended brand air purifier warranties range from a standard 1 Year Warranty to a Lifetime Limited Warranty.
