Blue Pure 511 Replacement Filter Compatible with Blueair Blue Pure 511 Air Purifier, 2-in-1 H13 True HEPA Particle Filter and Activated Carbon Filter, 2 Pack

When we first got our Pureaire air purifier, we ran it on high in the bedroom for a couple days and the air smelled very clean. These filters did the same thing after we replaced the originals due to recent wildfires. I'm satisfied they are good quality and will last about as long.

Good quality and easy to install. I’ve ordered these several times and always receive them promptly

I would buy it again

The media could not be loaded. This is a review of the initial build quality of the filter. It looks directly equal to the brand name manufacturers from Blueair .the thickness and conatruction feels and looks like factory. I will see how it does over time...but first impressions of the quality of the build are on par with the original equipment

Light came on as advertised. Builder, easy to change seems to be doing a good job.Can tell a difference in The air Quality.

I love my air filter. These replacement filters were quick to arrive and fit perfectly in my air filter. I have been using them for over a year now and have nothing but good things to say. The air in my home feels and smells much cleaners

I love these filters for my air purifier. It traps all the gunk the purifier collects. Noise level depends on the kind of purifier you use, I’m sure. Very functional, the images attached are a new filter compared to one that’s been used for about 5 months. I really should change our more regularly to ensure a cleaner breathing space, but I’ve come to find these work alright for the time I’ve been using them for. No bad scent with these, size is perfect. I wish they came in larger packs so I could buy more for less.

These ship easily because they fold flat. Fits the purifier perfect and made a big difference in the function!
