  • Amazing. Safe. Works.
I had first purchased a blueair 311 auto but discovered testers showed it produces Ozone! Research it. They say it doesn't "emit" Ozone but i didn't trust that as the wording on the Blueair site seemed shadey. Researching I found others had done testing and said that it had released Ozone. That scared me. So now I have this guy. It really moves air. It has three speeds. Low you cant hear it but can feel some air moving. Medium is where I usually keep it and sleep with it on med too. Makes a nice, unobtrusive white noise. High is a bit loud in the bedroom but would be fine in a bigger room or if your not trying to sleep. I got the carbon filter too and the room feels very fresh. I plan on getting a second when I can. As for the dial. I have no problem turning it. My husband is not a fan of it. Kinda like a rotary dial. If I could add one feature it would be a pre-filter because we have a cat and it would catch a lot of hair, probably extending filter life. I recommend this filter because it doesn't produce ozone or Ionize the air. (Read up on that, it's not something you want) I also got the 3 year warranty because you just never know. ... show more

  • One of the safest purifiers on the market as far as Hepa filter and EMF emitted.
I have 3 of these now in my apartment. Took months of research and sending back a few other brands, to find the crem de la crem. This has the most simplistic features and it's actually cool that they have an oldschool dial to it. One reviewer complained about it, but that's what keeps the EMF emitted from this purifier very low. When electronics have fancy panels and LED buttons, the EMF radiation emitted is very high and not good for your living environment. These push a good amount of air for the size of them. They use PET/Polypropelene filters and not fiberblass like a lot of companies, so you don't have to worry about harmful glass particles shedding over time and getting back into your air. The particles that would maybe fall off are not harmful to the lungs. These use a Hepa 11 filter, but that's because you can push more air through them. They still filter the same as a HEPA 13 down to .01 microns, but the efficiency is 95% first pass as opposed to 99.7% I believe. I run mine on setting 2 as it will filter better by not rushing air too fast through it. Not to mention setting 3 is a tad too loud. Setting 1 does nothing and should never be run on it. My only suggestion is if they increased the wattage used on setting 1 so it actually moved a tad more air, yet stayed quiet. And if they added one more setting and made it 4 settings total would be absolutely perfect. Setting 3 now should be where setting 4 is in the future. And the new setting 3 should be slightly faster than setting 2 now. Overall though you won't find a better purifier for a 500sq ft. space. This thing destroys what's on the market. Another reviewers mentioned setting 2 being too loud. Not true at all. I could be right next to this and make a phone call easily and I doubt the person on the other line would hear the wind moving at all. I was buying these from China before they became available on here. Had to annoy them on Instagram to get them to put these for sale here in the US, because shipping will deter tons of buyers. And walla! They are now up for grabs. Thanks Smart Air. Your team puts insane amounts of dedication to studying air pollution and how to have the safest, most effective products. Not to mention the EMF that's emitted from the Smart Health is very very low. Surprised you don't market that. Most other purifiers will hit you with higher Electro Magnetic Fields. Maybe one other edition would be shielding the electric cable with aluminum foil on the inside so this puts out almost no EMF. But hey, I'll take what you guys have! ... show more

  • very well made but noise levels were disappointing
I have purchased several of these for our office. We have the Smart Health Air Blast in our main area and I love it. Even on the highest fan setting, the Blast is quiet. These are made by the same company but on anything above 1 fan setting, its noticeable in a private office. Despite that, well made and very easy to change filters. ... show more

  • Effective air purifier in great design
I have run Smart Health Model S in my office for a couple of weeks now and have already colleagues asking me about it. I have followed Smart Health’s research on indoor air quality for a while, including their research on DIY air purifiers and tests of various HEPA filters, but decided to wait until this model was available on Amazon, for cheaper US shipping. Ultimately an air purifier is just a fan next to an air filter. Some air purifiers try to make this more complicated than it should be, with inscrutable controls and questionable features. The Model S has a simple dial with an “off” and three “on” speed speed settings. There is a carbon filter for odors and VOCs, and a traditional HEPA filter. All this in a great design that looks like an attractive piece of furniture and not an oversize gadget. I measured the wind speed with an anemometer and tested the purification with a PM sensor. I’m satisfied with the results in my relatively small office, and I think it would be fine in a smaller bedroom, but I don’t know how it would perform in a larger space. This model is probably too small for a larger living room. The three fixed speeds keep it simple, and having just three speeds is common for air purifiers. Most of the time, I keep mine on speed 2, and sometimes lower it to speed 1 if I find it too loud. Speed 3 is quite loud and I would only use that if it’s particularly dusty or I want to clean the air quickly. The one thing I wish for is a speed between 2 and 3. I haven’t had to change the filter yet. It’s done by holding down two handles on the left and right sides, and lifting the top of the unit which contains the fan. It’s easier than it sounds. The handle mechanism (see photo) is quite well designed. Inside, you’ll see the HEPA filter, and the carbon filter below it. Unlike some other air purifiers I own, the plastic on this model has a surface that doesn’t appear to attract much dust itself, which is a bad quality in an air purifier. ... show more
