Fantastic air purifier

We own 7 of this air purifier. It's a simple machine but does a great job filtering the air. Carbon pre filter plus the hepa filter is all that's necessary for a good filtration job. Doesn't take up a lot of space but does a job as good as a larger one. The easy filter changing does not take a lot of time, simply easy change! We owned a lot of air filtration up systems including very expensive towers and this remains to our favorite. We have more than one in opposite ends of the rooms, works great!

Clean air

We experienced a leak in our house and needed the extra HEPA filter for moldy smells. This has left the air fresh and much "cleaner smelling". I really enjoy these filters by GermGuardian this is our second one. It is a little too noisy at night on the lowest setting, but I don't sleep well without it running. Yes I do recommend these HEPA filters 5 stars.

It works

I bought this for our boat. We also have a GermGuardian purifier in our bathroom that works well. I wish this was a little quieter, but overall it works to minimize odors.
