Great replacement filter
The media could not be loaded. I’m happy with this filter. It’s fits perfect in my blue air 403. Air flow seems the same, but I usually keep on low. Super easy to replace. As some have mentioned, there was a slight plastic smell at first but it went away in a day of running it.

Lasts Just as Long for Less
This is my second purchase of this brand and I have been very pleased with its performance, which from what I can tell is comparable to the official branded ones. Same results for significantly less cost.

Easy process
I ordered this filter based on price and availability. The Filter has not yet been put to use. The quality appears to be good and only thing now to do is test the longevity which will either result in happy return customer when time to replace or search for another supplier.

Blueair 400 Series
Fits like a glove. Direct replacement for our 10 plus year old and going strong Blueair air purifier. Works perfectly.

Can't tell difference between this and OEM Blueair
With the OEM Blueair filters skyrocketing in price over the years, I decided to try this after market filter. Everything seems identical to the OEM Blueair filter. Even the writing on the filter looks like the OEM Blueair filter. My filter was used so I could tell them apart, but if a new OEM Blueair filter and this filter was mixed up like the shell game, I couldn't tell them apart. It fit into my machine the same way as the OEM Blueair filter fit and the machine seems to function just like it does with the OEM Blueair filters.

Great option that’s budget friendly
The price is almost half of name brand. Will update review once used to see if it works as well collecting dust. But so far satisfied
