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

Something is wrong with the filters. Smells like low quality toxic plastic chemicals. Ironic for the people using this machine because of the chemical sensitivity. This didn't happen to the filter 2 years ago so it's a new problem but it rendered the car unusable. I hope the company can fix this. I would also like to know what my kids and I have been breathing for the last 2 days? That can't be healthy and it's a shame we experienced that.

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…

Terrible chemical smell. I changed the filter and smelled a horrible chemical oil smell. At first I thought I had put the filter in wrong or something because I've never felt anything like this from an air filter. I cleaned the whole unit and put the filter back in place and again it smelled like horrible chemicals and was giving me a headache. I had to turn it off. That can't be healthy. I'm reading other reviews right now and I know I'm not the only one feeling this way. If Blue Air people…

The replacement filter made my whole house smell like strong chemicals. It's a terribly poisonous smell. I have had my car for almost 4 years and have never had a problem until now. I called Blu Air to report the issue. They apologized and said it happened with 1:1000 filters and sent me a new one. The new one smelled horrible too. So they sent me the 3rd 3rd was just as bad! I'm so frustrated to think I spent hundreds on our car which now can't even be used unless I want my house to smell bad…

The last three I bought smelled like glue or solvent The smell spread throughout the room and I had to turn off the machine. This defeats the purpose of an air purifier, so I finally got fed up with the smelly filters and donated the car. After some research I found out that the filters are made in India and they are not real HEPA filters but overpriced dust filters. I bought a Honeywell HPA300 and the filters last twice as long, filter the air better because they are true HEPA filters, and…

For some reason these filters are more expensive than those for larger Blueair filters. They work as advertised but the cost is silly. I started buying a universal filter to save money. If I had done better research I would have bought a different brand of hepa filter. If you buy four of these you will have spent enough money on filters to buy a good quality new Hepa unit. Consider offering this filter in bulk at a savings or discount. For this reason I am considering selling my Blueair and…

I have been a Blueair owner and fan for many years. I have two devices that clean the air in different parts of my house. Bought replacement filters here. My last order turned up and it stank really bad, some horrible chemical smell. It was much worse when I put the filter in the car and turned it on. I can't stand the smell. It's worse than a filter that doesn't work at all. I went straight to the Blueair website and saw other people complaining about the same issue. I am very disappointed in…

I hate paying that much for a filter as we have 3 of these units BUT I think it's worth it decided to buy a real model. I've tried several fakes from different brands and I just don't think they work as well as they seem to interfere with the automatic function. One of my devices kept switching between settings 2 and 3 and the only way to stop this is to turn off the automatic mode. That didn't happen with the Blueair filter. Replacing fakes, they also don't feel as messy as the Blueair brand…
