GENUINE HEPA PURE FILTRATION – Experience the power of authentic HEPA PURE air filtration. Genuine GermGuardian high efficiency HEPA air filters capture 99.97% of dust, allergens, and wildfire smoke particles down to 0.1 microns from the air. Our genuine filters effectively trap pollen, harmful bacteria, and pet dander from the air.
WHY HEPA PURE – HEPA PURE stands out with its multi-layer filtration technology. Backed by scientific testing, we combine extensive research and superior materials to outperform the competition. Beware of knockoffs that compromise on quality
PURE PARTS, PURER AIR – Genuine GermGuardian replacement filters guarantee certified fit and maximum filtration. Off-brand filters frequently fail HEPA testing standards, fit incorrectly, reduce efficacy, and may cause damage to your GermGuardian air purifier. Your purifier is only as powerful and effective as the filter you put inside.
REDUCES ODORS – The activated carbon pre-filter traps dust, pet hair, and other large particles, while extending the life of the HEPA filter. Treated carbon absorbs volatile organic compounds from the air and reduces odors from smoking, cooking and pets. The FLT21CB4 {ASIN: B08V98KPNQ} carbon pre-filters can be replaced every 2-3 months to help reduce common household odors and extend filter life.

SWFOTWSKI’s Verified Buyer – 7 March 2024

The Germ Guardian FLT5900 True HEPA Replacement Filter J is a reliable choice for maintaining air purifier performance. It effectively captures dust and allergens, contributing to improved indoor air quality. The filter is easy to install and fits the AC5900WCA model perfectly. While the price may seem a bit high, the quality and performance justify the cost. Overall, it’s a solid investment for cleaner air at home.
Gregg Antworth Verified Buyer – 11 March 2024

I have bought the filter twice. Very pleased with the performance, the filter catches the dust as promised.
Eco Verified Buyer – 20 April 2024

Works as expected.
Bhaj Ma Verified Buyer – 6 October 2024

I finally replaced my filter after almost a year (let’s be honest, it’s a hot penny for these bad boys). I live in the south and have CRAZY allergies. I take several meds, but they haven’t been cutting it, lately. After replacing my filter I can honestly say there is a significant improvement in my back-of-the-throat snot production. For this, I’m extremely grateful.
It also helps with the dust and pet hair accumulation on my surfaces. And perhaps I’m nuts (a distinct possibility), but I swear the air LOOKS and smells cleaner.
Worth the investment in my health and overall quality-of-life 👍🏼😁
Kindle Customer Verified Buyer – 1 December 2024

Love these filters they pick up a lot of dust. More than my furnace filter
IT’S ME SB Verified Buyer – 14 December 2024

This is a good filter for a great air purifier. I have owned so many air purifiers. I have spent 500.00 to 89.00 over the pandemic for health reasons for a family member, a sick dog, and someone with sensitivity. It is my favorite and most reliable, and not to forget a more reasonably priced system. The thing that annoyed me the most was my needing to be informed through research that some filters were $$$$ and needed to be replaced in 3 months. Tip: You should vacuum all filers between changing. You will see how much dust and dander you have by doing so and moving it around the room or changing rooms. Read the sq footage of what you need to accompany the area you are putting it in. I never knew any of this and had to learn the hard $$$$$ way.
Grammy Verified Buyer – 18 January 2025

Was appalled at cost for these until I found them on germguardianoutlet.com for a fraction the price. They are the same filters. Checked carefully as I thought they would be substandard considering the price but they are even in the same packaging.
Joseph Pegoraro Verified Buyer – 7 March 2025

seem to work just as well as the originals
MF Verified Buyer – 10 March 2025

Great item. It cleans the air just fine and removes the dust. Smell of the air is great! Fits perfect and lasts a long time. Great product and no noise level.
Anne S. Allen Verified Buyer – 27 March 2025

Fit my air purifier perfectly. Arrived in a timely fashion
Kent-o Verified Buyer – 4 April 2025

When researching air purifiers, a major consideration was the running costs. These are long-lasting and reasonably priced replacements.
xiang Verified Buyer – 2 May 2025

The listing shows “True Hepa” and product received is “Hepa”, per guardiantechnologies website, seems there is some difference, not sure:
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.
To be considered True HEPA by DOE (Department of Energy) standards, an air filter must remove 99.97% of all airborne particles as small as 0.3 microns in size. Using a True HEPA air filter is the most effective way to remove odor-producing bacteria, as well as minuscule irritants that can cause allergy and asthma symptoms.
Virginia Ward Verified Buyer – 4 May 2025

Replacement filters arrived in brown boxes instead of the ones shown and the quality of the filter is not as nice as the ones I replaced. The black foam that you vacuum to extend the life of the filter isn’t as sturdy as the ones I have purchased in the past and I’m afraid these will tear when vacuuming. As expensive as these filters are, I would rather pay a few dollars more for the same quality we’ve had than the same amount for lower quality.
Aurelia Garcia Verified Buyer – 9 May 2025

See photos. On the left is from a replacement set we bought about two years ago. On the right is what we just received. I’m extremely disappointed that the OEM has stooped to this level. The carbon is what absorbs VOC and the one I just received is practically worthless. The pleated filter still seems to be of good quality. But if you can order them separately, do it because it’s not like you’ll get anything better from GermGuardian themselves.
