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

these don't work as a brand. I installed them and within 24 hours I was having problems. I thought maybe it was a lung disease. However, I had symptoms such as throat constriction and difficulty breathing, coughing, watery eyes and copious amounts of phlegm. I am allergic to dust, as we have air conditioning and forced heating it is imperative that this air purifier and its filter work at their best. I had to turn it off to regain my composure. I quickly went to Home Depot and bought two, then went to the Honeywell website and bought an even cheaper one. Now I breathe perfectly.
