FAQs

How Do Air Filters Work?

Air filters remove airborne and particulate matter such as dirt, allergens, bacteria, dust and smoke from the air. Air filters work by pulling air through a filter and trapping the particulate matter.

What Does HEPA Stand for?

HEPA stands for High Efficiency Particulate Air, and is one of today's top trusted air purification technologies. Through tightly woven material, it captures airborne particulates as small as 0.3 microns in size, such as dust mites, debris, mold spores, pollens and pet dander. Particles that can trigger asthma or allergies typically range from 1.0–10.0 microns in size, and pesky bacteria particles around 0.3 microns in size. HEPA technology makes it possible to remove particles as small as 0.3 microns — making it a highly effective solution to remove potentially harmful particles from your indoor air.. True HEPA filters are highly effective to address your clean-air concerns. We recommend it as the most effective solution to protect you against dangerous airborne particles.

Why use Genuine GermGuardian Filter Replacements?

Your purifier is only as powerful and effective as the filter you put inside, and our Genuine GermGuardian replacement parts are essential for maintaining product performance. Each filter or bulb is designed specifically for a particular unit style. Not only will genuine replacement parts fit like a glove, but they also have the combination technology to match so that you can get the most out of your air purifier or air sanitizer.

What Is a Pet Pure True HEPA Air Filter?

Whether you have pets in your home or spend a substantial amount of time around animals, animal dander can be a large contributing factor to respiratory issues or odor-producing bacteria. Pet Pure HEPA filters are treated with an antimicrobial agent to inhibit the growth of mold, mildew and odor-causing bacteria on the filter itself.

How Often Should I Replace My GermGuardian Filter?

We recommend you change your filter every 6–8 months. Like other consumables, lifespan of a filter is based upon usage. Our air purifiers are built for constant daily use. If you use yours less frequently, your filter will last longer. You can usually determine whether you're ready to change the filter based upon its appearance. If it appears dirty, it should probably be replaced as soon as possible.

How do I reset the filter indicator light after replacing the filter?

Resetting the blinking light after replacing your filter requires a manual reset and differs per air purifier. Please locate your manual and follow the instructions. If you do not have your manual, you can locate it on Guardian Technologies website.

5.0 out of 5 stars Highly recommend - reviews debunked
Reviewed in the United States 🇺🇸 on June 29, 2020
I got my Germ Guardian 6 months ago and just recently my red light came in to change the filter. I was looking at the reviews on Amazon and saw that there were mixed reactions. I still purchased because some were positive and the price was better than other places! I’ve tried to touch on some of the concerning reviews I’ve seen and how my experience was similar/different.

Packaging: The package appeared to be just as expected.

Change in appearance: I saw a review that talked about how the filter Looked different and could be a knock off, but this doesn’t seem to be the case. My filter looked like it was good quality and there was an insert that talked about how the product was just redesigned to be efficient so it may look differently

Installation: Installation was super easy and the machine had helpful labels.

Frequency: I now know I should have been cleaning the black filter (not the white accordion filter) monthly so I’ll begin doing that. It recommends changing the entire filter every 6 months which is right when the light came on.

Red to Green Light: I saw someone post that their light was still blinking - After changing the filter just hold down the UV button for about 5 seconds and it will reset the light.

Overall, works great and many of the concerns I had previously from the reviews ended up being manageable! Save money and just purchase from Amazon. You can even set up automatic delivery for 6 months.
