Genuine Filter for Blue Pure 411i Max and 411a Max Air Purifiers

Genuine filter, easy to swap out, and instantly improved airflow. A bit pricey but worth it for cleaner air and a genuine filter

Helped get me through allergy season - a huge help! I used this in the matching Blueair filter in my bedroom - completely silent on night mode. No more waking up with puffy, itching, watery eyes.

I purchased this filter because a new neighbor would smoke outside frequently and living in Southern California our windows are pretty much always open. I found this filter to help so much with reducing the smoke coming in through the windows. I've also noticed that the air inside is generally more fresh. Smells left behind from cooking or our pets are also quickly filtered and less noticable. I highly recommend the BlueAir products

Always reliable.

Works great

Works as advertised. Maybe more costly than knock-offs, but I have confidence the filter is filtering as designed. With no-name replacements, I'm not sure and not willing to take the risk

I’ll stick with Bluair manufactured filter. Their machine does an excellent job so there’s no question I’ll purchase their replacement filter - stick with a winner. HIGHLY RECOMMENDED!

Perfect

It's far better to use original manufacturer filters for your air purifiers. They trap all the dust,pollen,smoke etc. that they claim...but only if using the recommended type and size filter. This particular filter is rated for my purifier and works great.

Great filter for my blueair air purifier, price was better than their site and I like that this filter had the allergy blocker. It seems to be the strongest filter of them all.

This is one of the best filters for the Blue Pure 411i Max.

Perfect fit and perfect replacement. Good product!

Perfect Fit for the Mini BlueAir 6" X 6" filter.
