(aka Smart Health) Blast Mini Mk II Air Purifier for Large Rooms up to 3075 sq ft, 36-49 dBA, CARB Certified, True H13 HEPA & Activated Carbon Filters for Dust, Allergens, Pet Hair & Smoke

We purchased two of these after researching single room air purifiers with high flow rates per dollar. Filters are reasonably affordable and last a year. The flow rate is really impressive and the sound is soothing (we run one while we sleep). It's hard to measure air purification in most contexts, but we do have a air quality sensor that shows a relatively quick drop in particulates when the fan is running. I love that the controls is a simple analog dial. There's nothing lit up flashing in our room at night nor are there a menu or options we're unlikely to use; just 3 speed options + off on a rotary dial. Nice and simple. Perfect.

Air. Cleaner has 3 speeds and is quiet. Cleans air effectively. No annoying lights at night. Well built in that the filters are completely closed from side stream air. Like 2 cleaners because both sides of cleaner has 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!

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.

It's not a bad purifier per day, but it's just lacking in enough areas to make it not worth the higher price. For one, it's kind of large for a "small" purifier. It may look stylish but the fact that it's a larger footprint that also needs to sit on the 4 legs in each of the 4 corners, it limits the places you can put it, like it's too big to fit on most end-tables or shelves for example. The only saving grace here is that it sucks air from the bottom and then blows up, so you can squeeze it into a tight space between things if you want. Second, it's not quiet. The lowest speed has little to no fan noise, but the motor hums a high pitch that is annoying. At higher speeds the fan is louder than the hum, but then the fan noise is high. I think around 58 DB at high speed which is louder than most large higher quality air purifiers, or at least large purifiers on a medium speed which end up with a higher cadr at medium than this does at high.

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!

Have been running this air filter in my living room for a year and haven't had any problems. I have it attached to a smart plug so I can easily set a schedule to turn it on during the day or control it remotely and that has worked well for me. I've checked with my particle counter that it improves the air quality as expected.

Great. Bought for my kids class at school. Easy to set up and quiet. Can someone post a link for the replacement filter and HEPA? Thanks!
