Lifelong customer

I use this product for years now since my poodles were diagnosed with allergies. I have the system on 24/7 and it has never malfunctioned. I don't see myself not having it working in the background. I feel it working... My dogs and myself have not suffered from allergies since. BTW, I bought this machine after a hurricane where both myself and my dog got eye allergies.

Excellent product for the money !!!

I have three of these air filters, two in Michigan and one in Florida, where I will be adding one more in the near future. They work very well, just as they are advertised. You can tell by looking at the filters. Air quality is important to me and I take it seriously. The air smells fresher and there is very little, if any, dust on my furniture. Thank you, again, for a quality product that does as advertised.

Dependable Pet Filter!

I have two air cleaners that I only use the pet filters in. One air cleaner is in the great room & the other is in my bedroom. Truly rely on these filters to keep my pet dander allergies under control. So far, no complaints with the filters OR customer service.

Great Filter Worth the Price!

Love the machine that this filter fits and I like it better than the other filters that are available and are slightly thinner does an exemplary job and It has truly saved my life from getting asthma attacks and I also could keep my cat! This has also let me live in the area of Texas that has many allergens.

Received filters quickly.

Quick delivery. Fits perfect and cleans air extremely well

By: Peter

Excellent filter

A great filter overall. The new one piece filter is not as robust as the older 2 piece filters but it still works well. We have 2 air filters and love them. If only the filters were a little less expensive. Vacuuming the filter monthly really helps in a dusty environment. Overall the best air filter system I have had. We have 4 small dogs.

Love this product

Really helps keep my sound allergies under control!

By: cswadner

Works as expected

Not too much can be said about this product. Either the filter works, or it doesn't. This filter works, does what it is supposed to do, and that's all I want. Little pricy IMO, so minus 1 star.

By: tkf

met expectations

it is Hard to get excited about a filter, but it fit and seems to be working! Would order it again.

By: LJ

just as expected

This replacement fit as expected. The original filter wore out far too soon so hopefully the replacement well be better

By: Michael Dooling

Works as it should

I found this filter at a great price, and seems to function perfectly to spec. Ordering and shipping were no-hassle, fast and easy. Will be ordering my filters from here in the future!

By: Deb

Great price

I paid an amazing price for this filter. If you go on the manufacturers site you will pay 3 times as much.

By: Dee "Aiea Mom"

Found it on Amazon!

I bought a hepa filter from Target and when I wanted to replace the filter, Target didn't have it. I searched for the brand of filter and went to their website and I wanted to compare prices. Amazon was cheaper. And I knew I would get it sooner than the manufacturer. When I received it and immediately replaced it with no problem. So the next time I need another filter, I'll just order it from Amazon!

Awesome purchase!

Same exact filter that was in the Purifier when I purchased it. Easy installation: Take old one out, connect the 2 new ones together at the tabs and push back in the direction of the arrow indicated on the filter.

By: E. Wise "Common place Shopper"

It fits

I was happy with the fit and quality of construction of this replacement. Other replacements mentioned having a cardboard frame, but this is basically the same filter (plastic frame) as what came with the unit originally.

By: Lynda Biedermann

Very good filters

The Germ Guardian true HEPA filters are excellent when used with the Germ Guardian air cleaner. Very Good price.

Air purifier

This is a replacement for our air purifier and it works very well and seems to help the air in the house. We have two dogs and their hair definitely doesn't seem to be floating around so much. We keep it clean and seems to be effective.

Germ Guardian filters. a simple installation

The manufacturer recommends replacing the filters on this air purification system twice a year. At six months, i ordered the replacement filters. When the new ones came, I took the old ones out of the machine, and they did indeed look ready for replacement. There were two of them, and they were both covered with grime and dust. I opened the box for the new filters, and noticed they had prongs to indicate they needed to be snapped together. Before I could even look for instructions for assembly, I managed to snap the two filters together and put them into the purifier. I'm not at all mechanically inclined, but the replacement was so easy that i did it in seconds. The machine fired right up, and i am again enjoying air purification in my room.

By: Stephen Padgett

air filter works fine

I'm happy with the purifier and this filter that goes with it. I could tell from the first day of using it that the air in the room seemed more crisp, definitely better quality.

By: Liz Whelan

Great product

Fits my Germ Guardian. The true hepa with pet pure treatment filter really does the job in clearing the air and eliminating odors. Its hard to tell we have cats now.

By: JF-Marietta, GA

Fits perfectly

Great replacement filter for our GermGuardian. It's our unit perfectly and was less expensive than I was able to find elsewhere at retail.

Clean Indoor Air

Filters smoke, cooking odors and pet dander. Plus it catches dust before it layers itself in my dining room. The best filter I have used, and I really give it a workout every day the house is closed up. The only problem: These are hard to find in the stores, even the ones that sell the GermGuardian units, go figure. The good part: It arrives quickly from Amazon.
