Great OEN product! Effective filtering device!

I've had my Guardian for 8 years and it works so well. I keep it clean and change filters on time. I highly recommend these if you have allergies, respiratory issues, live in a smaller place and cook often.

Is a great filter, Just wish it was washable and resuseable as the cost can run up fast.

My allergist recommended I get air purifier with a HEPA filter for my bedroom. This one works well. It traps quite a bit of dust and pet hair when I vacuum it out or change it when due. The filter itself lasts about for to five months, which is quite acceptable. The only negative is the price, which is $35. Together with the UV bulb at $25, the air purifier can be a bit pricey to operate. But it does work.

Bought this for our existing HEPA filter. My boyfriend has very bad allergies. Sometimes he will sneeze 10+ times in a row, and when he sleeps sometimes his throat closes up so it sounds like he is choking. He also has had asthma attacks when around animals he is allergic to, or even just sleeping on a pillow that was touched by the fur of an animal he is allergic to. However, this filter prevents pretty much all of that. We keep it in the corner on his side of the bed and there is a noticeable difference in his breathing When he has a sneeze attack, we turn the filter back on and it goes away in a few minutes. It was really easy to install, with instructions on the filter and inside the casing of the actual machine. Took about 5 minutes total to replace. Be careful, though. The person with allergies should not be the one to change the filter, or at least should wear a mask when doing so. If your allergies are really bad, don't even be in the same room. It's really hard to change the filter without releasing particles into the air. That said, there's really nothing the company can do about that, so I still give this 5 stars. We have the filter on probably on average 12 hours a day, and it lasts about six months to a year.

Perfect fit for my device

You can feel the difference

Clean air, ahhhhh

I bought the GermGuardian Air Purifier in anticipation of adopting a cat. I have it running on low all day, every day - so I've had to change the filter sooner than the estimated 6 months. In my case, I usually have to change it after 4 or 5 months and I've been using the GermGuardian for 2 years now. My husband and I have allergies to dust and dander, so this filter has helped tremendously in keeping that under control. I also love to cook, so when I'm making a particularly aromatic dish, I turn my air purifier on the highest setting while cracking the window open slightly. Yes, the replacement filters are expensive, but it's a small price to pay for cleaner, fresher smelling air. The difference in air quality is noticeable when you contrast the moment the 'change the filter' indicator comes on, to the hour after replacing it with a new one. To put it into perspective as to how many impurities have been captured by the filter, have a look at the comparison photo of an old vs new filter (the old, dirty filter is bagged in plastic as to not allow the dust to escape). It's alarming to know what we would be breathing in without the use of this air purifier filter.

The machine will show a warning telling you to change the filter. If you have one of these in-house, the job will be done in ten minutes. They can be vacuumed, extending the life of the filter and making your life easier.

This is good product.
