Review on AUSANAT Mini Portable Air Purifier: Car, Travel, Baby Stroller, Home- Office Use, USB Rechargeable, H13 True HEPA Filter by Rebecca Johnson

I love this air purifier. I set it to the lowest level because my room is small. On the lowest level, it's not loud at all. I use it at night because I suffer from nasal congestion. It definitely improved my stuffy nose and helped me sleep better so this is my win. I have yet to find out if it actually cleans the air because I'm running it on the lowest setting. I got it on the best day for about $33. I think it's currently selling for around $44. I like that it's portable. I think it would be good to use it in the car too. By setting it to its lowest setting, I can use it for two nights before having to charge it again. Update: I received this on October 14, 2020. Today is December 7th, 2020. I still only run it on the lowest setting at night. The filter definitely works. Today I took it out to check and the filter doesn't look like new anymore. I definitely love it and would recommend it to anyone. A replacement filter costs about $16, which I think is a reasonable price. I will update again if I need to change the filter.
