**This comes with the filter wrapped in plastic so that does need to be removed.** So, you do need to unscrew the bottom to get to the filter and take off the plastic cover. I recall that I almost missed doing that with my first one because I thought that the alert sticker referred to something else. I originally bought this for a trip last year. At the time, Minnesota was experiencing its second summer with poor air quality due to Canadian wildfires. This little air purifier uses very little power and plugs into any usb outlet. I propped it onto the console and plugged it into a portable charging brick (Anker’s 26800mAh - not sold anymore). It kept the air fresh for us. Then when we got to our destination, I used it in the bedroom. I bought this last summer and it’s still working. There are replacement filters sold separately which I get through the subscribe and save option. I bought another one again in last November, to use in another room. Seriously, it’s so quiet and compact - barely noticeable.

Elegant design. About 12 inch tall and 6 inch wide cylinder. Controls are touch sensor. Has three settings for fan speed. I run this on highest and it doesn't bother me. Has a blue light feature but I don't use it. Filter replacements are cheap. This is a great product for RV or small bedrooms. Smoke particles, pollen will be captured by the filter. You can run this on a 5V USB bank! Recommended.

Lo coloque en el cuarto de la casa donde tenemos la caja de arena del gato y ayudo mucho a reducir los olores, aunque si requiere colocarse cerca de la fuente del olor.

This is the third purifier I’ve bought from this company, I love them. Quiet, great for light sleepers, and very effective at removing both odors and smoke (we live in area that sometimes gets bad air quality from wildfires and my partner is asthmatic). The only thing I would mention is that the light is quite bright, even when turned off (can be annoying at night) but it’s easily covered by a piece of cardboard or cloth. Or, treat it like a nightlight! It’s also definitely small enough that you can keep them anymore without it throwing off the setup of your space.

This air filter is great for small offices and bedrooms. It helps cleaning the air. It has 4 speeds, the sleep mode is the slowest one and is very silent, while the fastest is pretty noticeable. So far I could see some dust in the filter but not much (I don't use 24h a day) so I believe it is doing it's job. I recommend this filter.
