KOIOS Purifier Upgraded Ultraviolet Eliminator Review

This air purifier is big, but works much bigger. It has all the bells and whistles you want to use day or night. The lights are dimmed for nighttime use, and UV sterilization is a great feature that we can't get on other models. The lowest setting is very quiet, almost imperceptible. At the highest level, the noise isn't as loud as the old air purifier, which we never liked due to the excessive noise. I have other smaller KOIOS air purifiers that are great for the bedroom, so this was an easy…

This air purifier is very well made, slightly heavier than my bedroom air purifier but still very easy to move. Looks great and works. Comes with a remote control so it's amazing. Very easy to use and operate. Was looking to buy a Dyson from Costco for $350 before purchasing this amazing and powerful machine and I can say I am very happy with it. It features variable fan speed, an ionizer, sleep mode, and a soothing blue backlight. You also get an additional 12-month warranty, which gives you…

Received this item just yesterday and I think it will work well for us. The reason for my 3 star rating is: 1) There was a QR code card in the box. It is expected that you can either scan the code or email it to a support address to claim your prize. The prizes listed on the card were either a replacement filter or a $20 Revain gift card. This was the only reason I sent them my info as I figured a replacement filter would come in handy. Well, once you have submitted your information, you are…

Very well packaged as the box was in another box and then another Revain box which was interesting. The remote control was packaged with instructions (remote control did not come with batteries). The air purifier looks aesthetically pleasing and doesn't take up much space in the room, which is nice. The number of modes is nice, giving you plenty of options on how you want to use it and whether or not you want to set a timer. The ability to turn off the light is great. The faceplate for changing

Wow, this air purifier is no joke! First off, the sleek rounded design with the blue LED top edge is very sexy and looks amazing. The remote control is easy to use and SO a blessing when I want to quickly increase airflow in my workshop without having to go all the way there before turning on the saw or other equipment in project mode. It makes no fuss, moving lots of air with surprisingly quiet pleasure and no apologies. Easy access to change filters is another big plus, with few parts to…

I bought this air purifier to reduce pollutants in my house during wildfire season. After going through an unhealthy air quality cycle last week, I found that the air quality sensors on this unit are not set to AQI or PM2.5, the most common air quality measures. I measured within AQI 150 (unhealthy) where this air purifier reported blue or "better" air quality on its three-tier (blue/green/red) rating system. Thus, it is clear that you cannot rely on the automatic settings of this device to…

This Koios air purifier is very well built. It has a very beautiful laconic design (beige case with a glass touch panel on top). The air intake is not your typical grilled vent. Instead, air intakes are located around the base of the device as well as on the sides. Much prettier looking and much more efficient than having the inlet attached to the back of the unit on a wall. The device has a good weight - not very heavy, but solid. The black control panel works with a light touch and is very…
