Smart Air SA600 Air Purifier - High Performance, Compact, Dual-Inlet HEPA Air Purifier for Clean Air with 99.97% H13 HEPA Filters and Carbon Filters

Have been running this air purifier for 3 weeks now and I have to say that it has made a difference in our air quality (as evidenced by the dust already on the filters)! We have allergies, a pet and live in an urban area so air quality is an issue for us. It is so quiet that I am able to run it on medium in my living area and I do not notice the noise at all. I could easily sleep with it on low or medium and not be bothered by the noise. It appears to be solidly built and I appreciate the extras in this machine that were lacking in my last air purifier (screen to hold filters in place, power saving mode while running, and dual-sided filtering). Love to turn the setting up to high right before I dust the house for the extra clean. A great buy!

I just got this air purifier so I don't know what it'll be like in the long run, but so far it's great. It seems high quality and has a sleek design. The highest setting isn't as loud as other purifiers, so that's a plus. The child lock is also a great feature. And I especially like the fact that the HEPA filter is made of pp/pe instead of fiberglass like most other air purifiers. Who wants to filter their air with fiberglass? I had to search hard for a brand that didn't use fiberglass and Smart Air was the only one I could find. I plan on getting more in the future!

I often have work in an unfinished basement, which has significant mold/mildew. I run this on full blast the night before I work and there is a clear perceived difference in the air quality. I no longer get sore throats from being down there.I can tell when I’ve forgotten to turn on the purifier due to the smell of the air when I walk down the stairs.

Spent an arm and a leg on 2 of these. Liked the fact they weren't inonizers. Well over a month of using them and they don't seem to be doing a thing. Filters are spotless which is impossible because of the amount of animals with pet hair/dander I have. My AC units have much more on them than these things do. I notice no improvements in the way the air smells either. There is no way to actually verify these things are doing anything except visually, which is what I am doing. I would love to leave these purifiers on high all the time but they're way too loud and low & med. seem to be to low speed wise. They have become very expensive white noise machines to me. I believe I wasted my money on these and I am disappointed in that.

A well built product that is basic but functional.

I love this product. It has multi filters on each side. Very quiet on 1 and 2 level. Not so much on 3. The lights go off while running which is nice so it keeps my bedroom dark. I can easily move it to my office.

If this product worked, I'm sure it would do a great job filtering my air. But it keeps turning itself off, and sometimes it won't come back on till days later. This started happening within a day or two of purchase.
