Does the work and noise acceptable
I moved into a new studio. There is a terrible smell from the last tenant, like sweeting feet odor. Everyday I am back from work, the smell knocked me down as I open the door. I got this filter to work for three days nonstoped, and the smell is completely gone. It does make a fanning noise like a laptop computer running 100% CPU. But the noise is acceptable. I placed it just 3 meters from my bed, I can hear it but it did not disturb my sleep. I think it does kills the air born microboitics, and therefore removes the smell. Because later I go traveling for a week, and unplugged the filter. When I return, the smell did not come back. This means it really works, and the smell which has lasted two months is completely removed without recovery, just after three days of usage.
