Review on Pre-Filter By Omaeon Compatible With IQAir HealthPro Series F8(S) And Pre-Max (F1) - Improve Air Quality by Angela Flores

This is a great filter. I have an enviroklenz and saw this and decided to try this as a replacement filter for that machine. It's smaller, but just by an inch around so it does leave a gap and I was aware of that prior to ordering. It fits the machine and seems to work as well.It is the same thickness, comparable quality by viewing. THe machines are similarly advertised and priced and I may fashion some styrofoam around the filter to eliminate that one inch gap around it. They are the same height or thickness.This appears to be a good quality filter and it seems to be of comparable quality to the filter that came with the Enviroklenz machine.
