An activated carbon mesh layer eliminates harmful gaseous pollutants such as volatile organic compounds (VOCs), tobacco smoke, and other smells. In addition, advanced polypropylene filter media removes particle pollutants down to 0.1 micron in size from your indoor air, such as pollen, dirt, and pet dander. Using a 360-degree air intake and up to 4 times the filter surface area than competing replacement filters, the Blue Pure 411 Particle and Activated Carbon Filter lasts longer, on average from 6 months to a year.

NO COMPARISON – 4X FILTER SURFACE AREA & 360 AIR INTAKE: Blueair models with HEPASilent's mechanical and electrostatic filtration produced higher CADR, lower noise, and had lower energy consumption vs. the same models with only mechanical filtration (H13 filter). *Tested on E.coli, Influenza A (H1N1), A.niger with a minimum reduction rate of 99.9% in 60min

This filter works really well and keeps the air fresh. Easy to install and does its job effectively. Definitely a solid replacement for the Blue Pure 411 series!

I am subscribed to receive a filter every 6 months and it works great. The filter always fits snug and grabs up all of the dirt & dust.

I currently have a BlueAir 411 that has been great. It does the job. However, this is the first time I’ve ordered a replacement filter.I was unaware that there is a HUGE difference between the 411 and 411 Max purifier filters. This is my own fault for not paying careful attention, but I thought 411 was the sizing so I ordered one. It does not fit my 411 Max purifier. Warning to others - you don’t just need to know whether you have a 211 or 311 or 411 purifier. You need to know all of the other small numbers and descriptors (e.g. 411+, 411i, 411a, Max). Hope this helps prevent this mistake for others.

I’ve bought this filter for the third time in my life since I’ve bought 411 model of air purifier in 2020. No issues at all.
