• Room Air Purifier Buying Guide

    What you need to know to choose the device and filter that’s right for your home.

    • As an “air aware” homeowner, you’re likely attuned to the air inside your house, and have already taken steps to make it as clean as possible for you and your family by keeping up with HVAC servicing and filter changes. But if you’re ready to take indoor air quality to the next level, a room air purifier can help. Here’s what you need to know about the device to help you choose the best fit for your home.

      Benefits of air purifiers

      There are so many factors that can affect air quality—from the good vibes (the family dog, candlelit dinners) to the bad elements (humidity, cold and flu particles, outside pollution). Think of an air purifier like a one-room booster to your home’s overall indoor air health, trapping dust, lint, mold spores, bacteria, dander, smoke and more so you can breathe easier.

      Room air purifier sizes for every room

      When considering air purifiers, it comes down to picking the appropriate unit size for the square footage of the room it’s intended for. Filtrete™ Room Air Purifiers come in small, medium, large and extra large for rooms measuring 110 square feet (or smaller) up to 370 square feet. Unlike HVAC units, room air purifiers are portable, so you can move them from space to space, or purchase a couple for the high-traffic areas of your home.    

      Filters to fit your needs

      Choosing a Room Air Purifier filter is not a one-size-fits-all approach. Think about your specific indoor air quality concerns and what you hope to achieve with your air purifier before selecting a filter. All of our filters, Room Air Purifier filters included, work to trap allergens, but there are additional variations that remove bacteria, viruses, odor and ultrafine particles 1,000 times smaller than the human eye can see.     

      Also note the difference between “true HEPA” and “HEPA-type” filters. True HEPA filters go through special testing to ensure they trap 99.97 percent of particles that are 0.3 microns in diameter. HEPA type filters do collect lint, pet dander, pollen and dust, but they don’t meet the same industry standards as true HEPA. HEPA type can also have a varying range of efficiency and minimum particle size cleaning. Whichever filter you choose, be sure to select the correct size for your unit.   

      Easy to use

      With Filtrete™ Room Air Purifiers, it’s easy to have a set-it-and-forget-it mentality. Three to four fan speeds allow you to choose the setting to suit your preferences, and an electronic filter life indicator will alert you when it’s time to change the filter (every six or 12 months, depending on which filter you use).
