woman shopping on FilterQueen

You’re ready to invest in an air purifier. You know it benefits the health of everyone at home. But now, deciding on the right one seems overwhelming. How do you figure out what's most important when purchasing an air purifier?


Since COVID-19, numerous air purifier companies popped up to capitalize on our fear and the skyrocketing demand for clean air. This makes your job even harder because it’s tough to know who to trust — and if the product really works.


As an industry leader, FilterQueen has crafted the best air purifier on the market (and this handy guide for easy reference). We’ve been in the business of improving indoor air quality since 1928.


Today we’re giving you powerful information to make the purchase that’s right for you. Understand how particle size, MERV ratings, maintenance, run-time capability, and room size all add up to your optimal air purifier investment.

Particle Sizes: Getting Down To The Nitty-Gritty

Indoor air pollution causes serious health problems. Investing in an air purifier gives a simple solution. You can easily protect yourself from the numerous harmful toxins we encounter daily.


All those contaminants that linger in your air are particles, and we measure their sizes in microns.


With air purifiers — YES, size matters!Understanding particle sizes and filter capabilities are critical because the filter determines whether or not it can capture and trap specific pollutants.


If an air filter can’t trap pollen particles and you suffer from allergies — you just wasted your money!Or if you’re trying to limit bacteria and viruses loitering inside (who isn’t, after the last two years?), you need to know the air purifier you’re buying can do the job.


Standard HEPA filters remove 99.97% of particles down to 0.3 microns.


FilterQueen’s Defender air purifier is 3 times better than HEPA and removes 99.99% of harmful particles down to 0.1 micron.


You can easily recognize FilterQueen’s dedication to clean air by its commitment to putting the Defender through independent testing against SARS-CoV-2.  The result? It eliminates 99.9% of the virus from the air — and destroys it! These independent test results are verified by the CDC-recommended MS2 Bacteriophage testing process set by the FDA guidelines.


Pay attention to the particle size capturing ability, since not every air purifier has the same capacities. 

The Basic But Important Facts About MERV Ratings

Minimum Efficiency Reporting Values, or MERV, measure a filter's performance on a scale of 1 to 20. In a nutshell, the higher the MERV rating, the better it can trap harmful toxins when going through an air purifier.


It’s important to understand MERV when looking for the best air purifier because its value tells you what you’re getting out of the filter. Poor indoor air quality has known negative health impacts (likely one of the reasons you’re ready to buy one). A quality filter — from a quality company — makes all the difference.


FilterQueen’s Defender holds a MERV 19 Rating!


We always strive to go above and beyond the standard — and our MERV rating proves it. The Defender ranks as an FDA-Cleared Class II Medical Device, so you know you're investing in quality with our air purifier. Our devices are proudly placed in healthcare settings for ultimate protection of the most vulnerable populations.

Low Maintenance and 24/7 Capability

You likely fall into one of two categories: you care deeply about how much maintenance a purchase you’re making involves, or you don’t. Most of us fall in the first category. The last thing you want to do is buy something that adds to your already full plate…No thanks.


Make note of:

  • How often do filters need to be changed?
  • Can the air purifier stay on 24/7 — safely?
  • Does it have to be placed in a certain direction?

Changing a filter every 2-3 months can get expensive fast. Changing a filter once  a year (like with the Defender) sounds reasonable. And, since pollutants never stop, you want an air purifier with 24/7 run-time power. (And yes, the Defender has that too!)


Putting your air purifier in any direction allows convenience and ease, but some don’t offer this option. Many people like the relief of putting an air purifier in the corner, so it’s out of the way, but still on the job. The Defender air purifier conveniently offers a 360° air intake. You can place the device however you like!


All these small maintenance and run-time abilities add up to an efficient air purifier. 

Why Room Size Matters

When you understand particle size and MERV, the next thing to follow is room size, right? You need to know the size of your space to make sure you’re protecting yourself the best way you can. Not all air purifiers effectively clean the same amount of space.


COVID made all of us more aware of room sizes and how far six feet away really is. Similar to six feet being a measure to protect yourself during the pandemic, air purifiers can only handle so much space to safely clean the air.


The Defender purifies spaces up to 700 square feet. From your bedroom to your living room, you get quiet, constant protection with our air purifier in your home.
