Review on Honeywell U Filter HRF201B: 4 Pack Replacement Filters Compatible with HHT270, HHT290 Series by Daniel Jackson

These filters are perfect for my Febreeze Hepa Fiter air cooling towers and are MUCH cheaper. I run four of these towers in my house in different rooms/districts. After using them for several months, I opened the back of the blocks and they collected the same amount of dirt as the branded filters. I haven't noticed any additional accumulation of dust and particles around the house, so they seem to be working fine. I will buy them again.
