KOIOS Air Purifier: 3-in-1 True HEPA Filter for Cleaner Indoor Air

museart: Overall, I like this machine. It works well in small rooms, but the one i got had a defective fan. Customer service was surprised that I had called them and seemed to be at a loss as to what they should do. Finally, they asked for a video, so i made one and sent it to them. The good part was that I did not have to return the old one. A few weeks passed, then Amazon sent me a new one.( why this didn't happen in the first-place, still puzzles me ) The new one is working still working well, after just over a year. The thing to know is that more than a few companies make this exact design, so I would recommend just buying the cheapest one. They are all the same design. I would be a bit worried If I spent a lot of money with Koios though, due to the customer service.

Amazon Customer: I like the size of the unit. It is easy to replace the filter. The high speed setting is quite noisy and could be a problem if you are a light sleeper, however, the low speed is acceptable. It's nice to have a night light that can be switched off if you don't want it.

Confirmed Customer: My kid came out of daycare around 5:30 and threw up all over the parking lot. Get home with a high fever, it's chaos. One of those both ends virus things that kids are notorious for. The kind that makes you wish you could just die instead of ever experiencing the sweaty death diarrhea and vomiting it brings. Anyways. After finally getting her to bed (lots of bodily fluids, bed changes, eventually purchasing an air mattress and sealing her into the movie room) it was like 2 or 3 in the morning. Maybe 4, who really knows. So I was browsing air purifiers so that myself and my husband and my other 2 kids didn't have to pass around the death bug. Settled on this. Ordered it. Delivered by like 10:30 am. Suited up, set it up in the movie room, carefully placed food, water, meds, sealed her back in. This thing has amazing circulation for how small it is. No one else got sick (it has been about a week now I think, but idk for sure I don't know what days are anymore). And the kids allergies are better because I have since placed it in their room. It sounds about like like fan and I just placed an order for 2 more for the other bedrooms in the house (large bedrooms and the movie room we used...

Teresa Matson: I bought two of these filters one for my bedroom and one for my small kitchen and they work great for minimizing dust and removing kitchen odours

D.JonesD.Jones: 11/17/2019 UPDATE: I've been using this air cleaner now long enough to give it a fair review. It works great. The air is noticeably cleaner. I have a large pet parrot and the feather dust is a challenge for any air cleaning device. It's doing a great job. Also, I contacted customer service about the light and they were very helpful. There's a video in the video section of the listing that shows you how to remove the LED lights. Also, customer service told me that they are upgrading this model to another one that has a light shut-off option. Even though it's too late for me, at least they are listening to customer feedback and making necessary changes where needed and wanted by customers. Overall, I'm happy with this unit. Thank you customer service for your help.

It's hard to rate this honestly, because I've only been using it for a month.
1. The noise level is good. It's alot quieter than previous air purifiers I've had.
2. A big negative for me: The light is extremely bright BLUE AND YOU CAN'T SHUT IT OFF. Why would they make this machine with a light so bright that it says on all the time? I use this in my bedroom, so I had to shut it off for the night! Defeats the...

Jacqueline Locke: I bought two of these air purifiers and I love them both. I have one for my bedroom at home and one at my desk at work. I was having tons of problems with allergies especially at work. There is definitely something that I'm allergic to at work and there was a Monday that I could just feel like my airway was becoming really irritated and I was short of breath while standing and had to sit. I did end up with an allergy attack but the next day, Tuesday. I could only handle about 2 to 3 hours at work before I had another allergy attack. This time my inhaler didn't work and I had to leave work and go get a breathing treatment. On Wednesday I just went on Amazon and found this air purifier and it fit all of my requirements. Friday of that week I brought the one in to work and I haven't been sick at all since then!!! The downside is that on high the air purifier is not quiet but it is like white noise. And then the one at home. Okay, it is bright in the dark. People have added photos of the air purifier in the dark and it is bright. However, there is a little trick to take care of this situation. The blue light that goes around on the outside is about a 1/2 inch thick which is the same...

Hermetic Sage: I love the function of this product. It helped with my chronic cough from environmental pollutants so now I do not cough anymore. It took 7 weeks from coughing for 1.6 years to resolve. It is however very bright and the light can be covered with a headband, but the base still glows. Great for daytime use, but not recommended for night use if one requires complete darkness to sleep (like me). But you could always get an eye mask.

Amazon Customer: It has two settings, high is louder but it's not 'loud'. I quite like the white noise, actually, and have no problem sleeping with it on high. Low is near-silent. Yes, it has a blue light that's on whenever the machine is on, this helps me remember to turn it off. There is a plastic-y smell when you first run it, and it was gone by day three. It's been highly effective and helped me so mich with my allergies and asthma. I love it. Very reasonable. Good quality. Zero complaints whatsoever and their staff is fantastic.
