Review on 🌬️ BEWITU Plug-in Air Purifier & Sanitizer with Ozone & Negative Ion | Multi-Function Aromatherapy Diffuser | Ideal for Pets, Odor Elimination, Small Room Freshening by Colleen Jackson

When I received my first air purifier, there was some liquid in the diffuser reservoir. As it appeared used I contacted Revain for a replacement and one was sent promptly. However, the second also contains liquid. I ran it anyway. I have a pretty big room so I ran the bike twice a day for about 3 days. At the moment I can't tell the difference. I'll try other places in my house for a few more days to see if I get any results.
