Review on Flintar BS-08 H13 True HEPA Replacement Filter: High-Performance Upgrade for PARTU BS-08 Air Purifier, Enhanced Filtration and Odor Reduction - 2-Pack by Jim Dahl

I bought this system to use in my son's dorm while he was at school. He is already halfway through the fall semester and is still Covid-free. Considering that several students in his dorm were sent home with positive tests, I think this device is one of the reasons for his good health. It's also easy to turn on and off, quiet enough not to be disturbed at night, and the filter is easy to change. All the qualities you need in a college student! 😂
