These filters really work!
With minimal pm (vacuuming the prefilter once a month) and a new allergenblock filter every 6 months on my 4 Blueair air purifiers, the air quality on 3 levels of our home is amazingly light and fresh. We have 2 domestic longhair cats who get brushed every day, but their coats still shed like crazy! I have been able to stop allergy meds altogether, and breath easier with these allergenblock filters in all of my purifiers. These run on automatic 24/7, and I wouldn't exchange them if offered for FREE!!! Thanks Blueair!

Thank you for sharing your valuable feedback! It is so wonderful to hear that! Getting off allergy medication completely while living with two shedding domestic longhair cats is no small feat, that is the ultimate test for an air purifier setup. Running four purifiers on Automatic 24/7 across all three levels creates a continuous filtration blanket that catches cat dander and floating fur before it can settle. Thank you for sharing such a great success story! Enjoy that fresh, easy-breathing air and quality time with your cats!

I ordered new filters a month ago and am still waiting
I ordered new filters a month ago and am still waiting. This is the order number: SO-*****. I ordered the new filters through the control app on my phone.
Do you have any idea when I should expect this $100 order?

Just say NO to dog and cat hair floating through the air.
I haven’t had to continually deal with dust and animal hair clinging to my electronic devices. Gonna need another one soon.

Waiting to see.
This is a new purchase for me (5 months). I'm waiting to see when the unit indicates that I must replace the filter (which I've already bought). I won't really know how satisfied I am until I take out the old filter and get an idea of how much "stuff" it has saved me from breathing.

Very happy with our new BP 511i Filter
Set up and initial / continual operation no problems! Also ordered / received 2 replacement filters for use way on down the road! Seeing excellent results - better air quality.
