   Pros: 1. The machine does a good job of cleaning the air and removing odors. 2. It has a very quiet low speed for night-time use. It’s almost silent, but I have a hearing impairment and those with better hearing may disagree. 3. The device as a separate ionizer and UV-C germ killing lamp. These can be run separately, together, or not at all. 4. There is an automatic shut-off option—user-definable at 2, 4, or 6 hours. The user can also disable the shut-off option. 5. The filters fit nicely into the chassis. This means that the air is properly forced through the filters rather than around the edges. Cons: 1. Panel LED’s cannot be turned off. This turned out to be more annoying than I realized at first. In fairness, the manufacturer clearly indicated that the user could not turn out the lights. While these blue lights do not seem bright in the daytime, they are disturbing in my bedroom at night. Blue light is reportedly disruptive to sleep patterns. I covered the panel for night-time use by using a piece of thin corrugated cardboard. I used thin stock because the switches are sensitive to pressure, and because I could shape the cardboard to fit the curve of the panel. I used duct tape for the “hinges,” and I recommend that you leave a little slack in the tape for this purpose. The photos show how I did this, and also I suggest that you leave an extra quarter-inch of cardboard at the bottom for a “lip” to open the cover. The device does have the ability to turn off the beeping sounds when pressing the switches. At this price point, I would have thought that the manufacturer could also have created an option to turn out the lights or even better, have them time out after a user-selected interval. 2. The consumables are expensive. $75.00 is highway robbery for a filter set replacement every six months or so. Also, the UV-C bulb needs to be replaced annually at $35.00.Three years of consumables cost more than the one-time price of the device, which itself is expensive. 3. The “high” fan speed setting is noisy, even with my hearing impairment. 4. For this price point, the system should include a hand-held remote control. Again in fairness, the vendor clearly indicated that the device lacked this feature.

   Very happy, put it in my basement to take care of cat box and cat food odors. It’s probably a bit small for the amount of sq st down there but it’s very effective. Had an issue with the buttons and the company took care of me ASAP. Send me a shipping label to send it in for review and I was back in business in less than a week. Great Customer Service.

   Very easy setup and helpful manual. Operational modes (i.e. Speeds, UV/ION and Timer) are simple to set and maintain. Immediately improved the air quality in my home office (days) and master bedroom (night). 2nd unit was purchased for downstairs living room.

   

4. Allergy Sufferer Verified Buyer – 2 May 2025

   Since I’ve used this in my bedroom, I haven’t woken up stuffed up and sneezing! I’ve suffered from allergies since I was a child and am severely allergic to mold and dust. I’ve tried air purifiers in the past but never felt they made a difference. This is the first time I can say that I truly see a reduction in my allergy symptoms at night and in the morning from using this in my bedroom, which is a large room. I also like the fact that the filters keep the air fresh which is great as I let my dog sleep in my room. I highly recommend this product!
