i purchased this purifier to lend it out for events in my city and it’s awesome! incredibly powerful & quiet, very sturdy. i love that it has wheels, i only wish it had some handles for easier lifting into my car (it’s heavy and awkward to hold for a weakling with short arms lol). i’m very excited to pass this thing around town and make events in olympia a lil safer!

Beefy Unit

I don't know if I missed it in the product description, but this thing packaged is over 75 lbs?? There was some difficulty getting it up the stairs into the house because of the weight. It was packaged well, there were metal corner inserts in the box to protect the outside of the unit. Corner inserts were dented pretty good but they did their job as the actual unit was perfectly undamaged.

Unit itself is exceptionally well built. Nothing "cheap" about it. No plastic, wheels attached, nothing to set up, just plug it in and turn it on. Relatively quiet, I keep it on the medium setting and it's a light white noise. The highest setting is a bit louder but just like any other stand-alone fan on the max speed. I can't tell yet how well it cleans/circulates the air as it's only been a few days, but the house seems to recover from cooking smells etc faster than before.

Overall very happy with the purchase.

I absolutely love the Smart Air Blast Mini - MKII!

I got this one for my house, which is small, about 900 square feet. I got the one with the VOC (carbon) filter. 

SARS-CoV-2 numbers almost at their peak for any time during the entire pandemic now, and many people have the misguided belief that covid is gone or that the danger has passed. It has become more important than ever and more challenging than ever to protect oneself from this airborne virus and others.

This Smart Air Blast Mini - MKII can play a role in your home in keeping viral load lower than it would be without an air filter, should anyone who lives in your home contract any viruses.

In addition to that, pollution is becoming an even greater problem and the wildfires in the summer have reached an unprecedented level, I see this as a wonderful investment in maintaining my health.

While it represents an investment for sure, the filters only need replacing every 2 years! That is very convenient for me.

It is also very quiet, except on the highest setting, but even then, it is still quiet enough for me to be on zoom meetings about 6 feet away.

Thank you Smarter HEPA!

Love this purifier

Just purchased this purifier and it works great. Arrived quick and despite its size it blends in well with my decor .

great for my kids' schools

I bought a pair last year for my kids' classrooms and have been really happy with the balance of volume versus cleaning power. So far, both kids have managed to stay healthy despite multiple COVID exposures at school, so I am glad to have this as one of our layers of protection.
