Quiet

Reviewed in the United States on April 5, 2024

Real nice . Perfect for my 250 sq ft bedroom. I like the night light. Well made, no problems. Small but efficient. I run it on low at night, and breathe better in morning.

Loud but works

Reviewed in the United States on April 22, 2024

It’s a little louder than I would like for it to be. I put it in my small office at work to get rid of unwanted odor, which it does.

Keeps my room fresh and is nice and quiet on the low mode

I recently moved into an apartment and the previous renters must have never vacuumed because there was an insane amount of dust! This purifier has been doing a great job at taking it out of the air and it leaves my room smelling nice and fresh. All for a very affordable price. Plus you get a free gift if you leave a review which is awesome! Would recommend to anyone who is having dust or odor problems. This product is especially useful because now I am spending so much more time at home due to the recent COVID-19 outbreak. Couldn't ask for much more for such a low price. The three modes are nice, the HIGH mode is kinda noisy which is fine to use when you are not around, the low and night modes are great and I can barely even hear it, it is not much louder than my PC.

I'm changing my review from a 4.5 to a 5 star...(going on 6 months of ownership). The KOIOS Air Purifier has been a life saver for me in returning to work, especially during this Covid-19 pandemic. I put it in my office and turn it on with the door shut to purify the air before I go in and work for 8hrs. The air smells clean and fresh. The night feature is great since the light is off and the noise is minimal. I bought 2 more for my family members and they have them running constantly in the babies bedroom and the office. It's performing like the Best deal out there!

I never had a air purifier this is my first and I enjoy every moment of it. I got it because of Covid for anyone entering my house it will remove any virus I’m on my family to clear the air.

I work in healthcare, I purchased this air purifier to use in my office while seeing pts. I bought this specifically for use in relation to Covid-19. I love that it is sleek and modern. I can adjust the fan as well as the night light. I will continue to use this even after the pandemic subsides.

Like it for home. But also like the portability such that we can take it to a hotel room when we travel during the COVID pandemic.
