Review on 🔄 Blueair 400 PF Replacement Filter: Enhance Air Quality with Single Unit, White by Marcos Olvera

For the second time in a row I received a replacement filter for my 405 which smells of gas. Blueair customer service informed me that only 1% of their filters are affected by this issue. If this is true, then the probability that I will buy two faulty filters in a row (ordered a few months apart) is 0.01 x 0.01 = 0.0001. From many other reviews on Revain it appears that this problem has existed for many years. Blueair informed me that they are moving production from China to the US for this reason.
