  • A purifier that actually does remove odors!
Holy cow, I'm beyond impressed with this thing! We have two aging dogs with bowel control issues, and their crates are disgusting smelly messes when we get home from work every day. Sprays just mask the odor, ozone generators are somewhat effective, carbon filters do NOTHING. I've tried a Dyson HP2 with some success, a Dyson Hushjet that did nothing at all, and a full sized Molekule purifier. The Molekule is very effective, but also sounds like a jet engine when it's at full speed. (It. Is. LOUD). The Kaltech mini lacks any "smart" features like the Dyson or Molekule, no wifi connectivity, no auto mode, no air quality sensors, and yet it doesn't seem to need any of them! Set to half speed, it's whisper quiet and within 30 minutes, there was zero odor! After 3 days of use, not once have I come home and smelled any sort of "doggy accident". It barely uses any power, but with it's small size and air intake, I would highly recommend pairing this next to a cheaper air filter to capture larger dust and allergen particles, while the Kaltech Mini handles breaking down viruses, VOCs, and odors that carbon and HEPA filters just can't do. It also handles odors in my 3D printing incredibly well, but only when placed next to the printer exhaust port. I would HIGHLY recommend getting the larger size model for controlling harmful VOCs for multiple 3D printers, but it's ability to mitigate any odors even when printing ABS is astounding! Overall, I would not recommend using this as your sole source of air filtration. But use it as an air scrubber paired with a cheap air filter for dust capture, and you'll be amazed at how well and quietly it removes odors and allergens, even compared to other air purifiers that cost $1,000 or more. ... show more

  • Fine product!
So quiet and good machine, the price is too high.

  • One of the greatest investments for air quality!
I'm a huge air quality guy and have bought so many devices to improve the room in the air. HEPA filters are great for micro dust and weird particles in the air. Ionizers are great for making the room smell sterile. However none of these products could really make the room consistently smell clean without sacrificing some important things. This device fills all of the gaps that air purifier have. Outside of raw dust filtering, this tiny little device uses a UV light against a titanium filter to clean the air. I can guarantee you that the weird musty/funky smell I had in the room (unless I actively used an ionizer) from food has disappeared thanks to this product. Yes, I only eat in my room, but this device makes it so that the room does not have an odor lingering throughout the day. I can definitely breathe fresher, as the air is having a lot of VOCs or unknown viruses/bacteria filtered out. It's not just a feeling I'm having, I can legitimately take deeper breaths of fresher air and not feel like I'm breathing in farts. The size is insanely small and yet packs a punch in my 150 sqft room. Sound is quite minimal at most levels, although the max level definitely is noticeable. Fan noise is very nice and not weird pitched at all (insanely important for me). Build quality is top notch and not of any cheap build. Easy to mount on places but I've left it next to the trashcan on its legs with zero issues. My favorite part about this purifier? It acts like a plasma/ionizer/ozone machine without any of the hilariously uncomfortable effects on the human body. I run it at all times in my room with zero fear of messing up my lungs or vision. Imagine all of the dirty things in the air killed (not filtered on a HEPA sheet) with a light that doesn't cause negative health issues. This is by far, one of the greatest purifiers you can get for your room. I've spent a lot on purifiers and this is definitely a top 2 or 3 contender purely off of it being great at everything but pure dusting. I actually do not think any mainstream purifier can properly fully dust anyways... ... show more
