I bought this plus another larger air purifier to deal with smoking in what is a roughly 1200sf open space with 12 foot ceilings. Not sure how either works separately, but together they work really well.This one is really quiet, but it does have a blue light that reflects really hard on surfaces. I haven't read the instructions enough to see if it can be turned off and just turned it around so it's not as bothersome. The size is great for sitting on a night stand. Very easy to set up.

Breathing alot better and breezier due to this life saver!

I set up an office in the basement of my house and it can get a little humid with that uncomfortable basement smell. And so I have a dehumidifier turned on during the summer. However, I felt I needed an air purifier to address the smell. And so I got this purely on price point and favorable reviews.I noted that some complained about the light. I don't think that's an issue at all. It's a soft blue light that is pleasant. I serves no other purpose than to add to a pleasant vibe. And I like it; it's not a distraction for me.There are two settings -- high and low. I don't like the noise produced by the high and so I have it at low where the noise is minimal and almost non-existent -- and it works to my liking at that setting. And so if noise is an issue, the low setting does the job.And the filter is not the higher end air purifier with two types of filters. It's really one filter that wraps around the bottom. However, having said that, it does the job I need it to do. The musty smell is gone.I give it four stars because having used it for about 2 months now, I guess I expected the filter to be a little dirty. However, the filter remains clean. I am not sure if it's because my basement is clean, or if the filter is not catching everything...

I have very sensitive dust/pollen allergies so I have purifiers throughout my house. I got this 1 for my car & love it! It’s quiet, fits directly behind the center console, & makes a noticeable difference in smell & dust/pollen in the Spring time. Everyone thought it was weird to have one for the car but it’s so worth it to me.

I really never write reviews but I have to for this one. I’m unfortunately one of those individuals who had their body forever altered due to living in mold for too long. I’m extremely sensitive to most indoor environments and needed a travel air purifier. I have some of the most top of the line air purifiers in the market (think $1K USD) and I personally feel this tiny thing holds up in comparison. I wouldn’t call it a replacement for the big ones but it is remarkably effective considering its size and price. I am shocked by it and have 3.

I’m not sure how it effective it is but it’s very quiet

Ordered this for my desk at work. Its small but big enough to make my space feel fresh and clean. It's quiet and it's attractive. I use the night light (blue soothing color) to make it look futuristic, lol. I now have other coworkers asking where to get one. I think its perfect for smaller spaces or areas such as a small kitchen without exhaust. It keeps the muggy smells away and also makes the space feel fresher to breath in Easy access to filter for cleaning and not to heavy to haul around, the cloth handle makes it easy to move from space to space. Its also brings a "little" longer than normal USB cord. So you can place it a bit further from the port than usual items. I recommend.

This product does not work. I ran it for a few days and assumed it was working because the fan was on. I checked the filter every week for a few weeks and it caught absolutely no dust or dirt. This product does not work. They set the return to only a month. It is very difficult to see if the product works or not in that time period. Do not buy this product, it is a glorified fan.The first picture I have is the filter after using it for a month. You can see that there is no dirt or dust. Evidence that the product does not work.
