Review on Blueair Blue Pure 211+ Lunar Rock Color: Pack of 3 Replacement Washable Pre-Filters by Impresa by Matthew Davenport

Arrived on time and well packaged. It smelled horribly of chemicals. (Flame retardant?) The product is a thick, pantyhose-like fabric that stretches slightly over 211+. Neutral light gray color as shown. The 211+ we ordered from Revain gives off a horrible smell like toxic paint fumes. I see a number of complaints about a foul smell in the Q&A. We didn't broadcast it. The manufacturer has not responded to the use. Revan sends a replacement. I see some people didn't have this problem and mnf suggested replacing the filter as requested in a question/answer but I still haven't responded (about a week since I wrote to them. They don't answer the phone).
