Good Product

Its a good product. What can I say? It came in a box and I installed it. Now it cleans my air.

By: Jeff

Not bad

The fan that this filter fits into is great. So I would recommend both the fan and this replacement. I would order more then 1 filter at a time.

Works good

This is the filter replacement for the air purifier we own. It works just fine. At this point in time, we switch it out about every 1-2 months bc we have an infant in the home. When we switch it out, we do notice it is pretty used up. So, it works for us.

Clear eyes

I live in downtown Boston. Love it, but when I moved in my eyes were always irritated. I looked like I had 2 pinkeyes. The germ guardian took care of that! These filters last a long time, so it's not a ridicules expense. When I change it, the old one is FULL of smog. Nice to toss that in the trash, instead of looking at red eyes everyday. I can only imagine the difference in my lungs!

Reasonable Priced

Great deal & I didn't even have to leave my office. Every pet owner who keeps their hairy pets inside should invest in an air purifier & those with severe allergies I really think it's a MUST HAVE. Just keep these reasonable priced filters changed regularly & enjoy the clean fresh air you breathe daily.

works just like it is supposed to

The filter arrived quickly and fit perfectly. It really helps to clean the air of dust and pollen. It has really helped with this years allergies

Good filter

A good filter is a good filter. What else can I say. I did my research, purchased a great air cleaning system and then the filter to go with it. What more can I possibly add. I do think items of this nature are over-priced.

Keeps my semi truck cleaner and dust free inside the cab. Purifies the air so I don't sneeze has much

Good replacement filter

Never any problems, a good fitting replacement filter. It's amazing how much crud is in the air and you can certainly see it when you replace the filter.

By: Lenny


It remove the smoke and works in my room like a charm and will buy this item again when I need a new one.

Heavy Smoker

Does a great job in freshening the smoke. I have been using germguardian for over a year, and I love it.

By: Antoinette Sweeten

Once again clean air

The product fit perfectly just like the original one for my table top air cleaning system. Next time I order, I will order enough for the year, so that I will get free shipping.

so far so good haven't had it to long, but it fits my machine and is working great. thank you

By: Justin M Archey

Filter is great!

Love the system: this filter traps particulates and the UV light kills bacteria....just wish the actual air cleaner these filters went into was built better.

By: steven shepard

just what the dr. ordered

the old filter was pretty dirty and my son started to have issues from the dust that was not being collected by the filtering unit. the new filters showed up very fast after purchase and were a perfect fit. the price was reasonably. thank you

By: Jim Parker

as expected

smooth transaction, product was exactly as advertised. Thanks.

We use the air cleaner for our small bedroom. Really helps with the air quality.

By: J-Houston

Does what it says

Great filter, low cost and does exactly what it says. I run two of these germ guardian systems in my home and I can notice a big difference. I live in a home with 2 cats (which I am allergic too) and these really came through for me. Super easy to change with no mess and no worries.

Excellent Filter for an Excellent Air Purifier

We own three Germ Guardian air purifiers and use them in our living room and 2 bedrooms. They are excellent units, and the filters are highly effective at removing pollutants from the air. They last up to 6 months if cared for properly. I turn off the units and remove the filters at least once each month to clean them of the dust that accumulates on both the top and bottom sides. This extends their effectiveness and keeps our living areas free of allergens.
