Great Product
A necessary item for my air purifier. Fits perfectly and eliminates the need for me to contact the parent company.

Great replacement air filter for my Blueair
My Blueair air filter told me it was time to replace its filter. I had sticker shock looking for a replacement and that this unit is not discontinued. This filter came in with no issues and it slides right in and started to work.

Just a Filter
Mine lasts much longer than indicated. Most of the dust etc. is trapped by the pre filter or winds up in the motor before it makes it to this filter.

Works as expected
Works as advertised. OEM guaranteed to work. This resolved my issue where the fan would be on auto and alternate between full-blast and minimal strength.

Always happy with this well designed filter.
This is a replacement filter, so it’s not the first time I’ve used this product.I really am happy with the design and “clean air results” of this filter.It definitely cleans the air, as the filter turns dark gray from the particles it scrubs from our air.It’s nice that these filters last a long time, too. We change ours ever 6-9 months.

BlueAir Filter ~ Works Like It Should
Because there really aren't any aftermarket BlueAir 7400 filters I ordered this and have absolutely no complaints. It's exactly like the one that came with my air purifier and they last a really long time. The price is up there but with the long life and no other cheaper ones around, it's well worth the purchase. Highly recommended!
