  • Extremely impressed!
I’ve been extremely impressed by this purifier unit! I was hesitant at first given very few reviews on Amazon before I purchased, but this has definitely held its own. I primarily use it to filter VOCs put out by a UV printer. I found that auto mode wasn’t quite enough to completely control VOCs so I have it set to ‘high’ whenever I’m printing and it’s perfect. Even on high, the noise isn’t any louder than a pedestal fan. ... show more

  • Doesn’t do particulates, too noisy for home use
The good: - Autodetect is sensitive and we think air is cleaner - It’s well designed and looks good on the wall - No filter changing was a big plus for us The bad: - Something that auto turns on like this needs to be much quieter in a home environment. - It also has a huge power brick you need to figure out how to hide. Don’t expect to hang it on a wall next to an outlet and have everything hidden away, as shown in the pictures. Those are showing it not plugged in! - It doesn’t remove particulates from the air, just smells and viruses. Good for covid maybe, but not good for smoke. You need HEPA for that. The claim this works for smoke is misleading. I think it could be suitable for an office or restaurant, but due to noise levels and lack of particulate control I don’t recommend this for home use. Maybe my expectations were unrealistic, but at close to $700 I want perfection. ... show more

  • Cool Looking Air Purifier
The design is modern and nice, looks like a decor when you mount on the wall. It is very clean looking and doesn’t look like an air purifier ;) I can’t wait to see the odor sensor works!!!!

  • Amazing product
I bought my unit in Hawaii during a Kaltech promotion at a department store. Although it was recently purchased, I can tell you that it immediately improved the air quality in my bedroom. I live in a damp, high humidity area, so mold and moisture is a problem. My nose is extremely sensitive to smell, so I KNOW that is making a huge difference. As far as viruses and bacteria, I can’t literally see that, but I trust Japanese made technology. The man who sold it to me said that it kills 99% of viruses and was tested validated at The University of Tokyo. It’s not cheap, but a lot less expensive than my $1k iQair that needs expensive new filters every year. I’m planning on getting more of these Kaltech air purifiers for other areas of my home and also as gifts for my parents. :) ... show more
