Blue Pure 511 Replacement Filter Compatible with Blueair Blue Pure 511 Air Purifier, 2-in-1 511 HEPA Particle Filter and Activated Carbon Filter, 2 Pack

Great fit for our model, just as advertised. Super easy to change. You can see a big difference in the old vs the new filter and how much the filter has picked up, yuck. We change it every few months as instructed per manufacture and the air purifier has stayed working great. Great deal on these filters

These are the filters for the Blueair Blue Pure 511 Air Purifier. We live in a wooded area with two large dogs and well the yard in the winter is a bit dry and dusty. I change our filters monthly in the bedroom and I have another one in the living room area. These are nice and affordable. Helps to keep the dust and dander down.

Perfect replacement filter, easy on, works great, and an excellent value.

Received what I ordered.

Small but important air cleaner. Allergies are always an issue but these filters are small but work excellent. I do breathe easier and these work great. I subscribe to save a little on these filters.

I believe these filters are doing a good job filtering my room and at an affordable price. Fits perfectly in my Blueair.

Good purchase, fits the purifier well

Works as advertised. Good value
