What buyers say about Blueair 400 PF Repalcement Filter, Single Unit, White
I gave the machine to the charity because I was fed up with the stinky filters and realized they were not true HEPA filters and were instead overpriced dust filters.
The Blueair replacement filter I have purchased many times from Amazon smells strongly of oil or chemical, and is not usable, even though I have been happy with it in the past.
It seems to do its job well and is a little expensive, but that's nothing compared to the Blueair purifier.
The Blue air device gets rid of a lot of the pollutants.
The filter is easy to install.
Common Questions
Does the metal part of the filter go in either direction when you open the side panel?
I was confused about it, so I asked a Blueair rep, and he said the metal side should be shown when the filter is inserted.
I just got a new filter and it has a strong smell, is it supposed to go away eventually?
I stopped using Blue Air a few years ago because it was so stinky and I couldn't tolerate the charcoal layer in the smoke stop.
How many filters are in an order?
The normal package has one filter, and it costs $50 each.
I am in an office without windows and our computer server room is in there, which is better the smoke filter or regular?
I think if you need a smoke filter, Blueair is better than you can get.
Where is this filter manufactured?
The filters are assembled in China and manufactured in the USA.
