BLUEAIR Protect 7400 SmartFilter, Genuine Replacement Filter for Protect 7470i, 7410i Home Air Purifiers for Virus, Bacteria, Dust, Smoke and Allergens

Used to replace old filters.

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

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.

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.

Blueair makes wonderful filters for their wonderful air cleaners. Everybody should have one.

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.

Perfect fit for a great air purifier

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.
