PUREBURG Replacement True HEPA Filters Compatible with Blueair Blue 3410 & Blue pure 311 Auto Air Purifiers, H13 Activated Carbon 2-IN-1,2-Pack

Needed a replacement filter, came quickly and fits perfectly

This product is perfect for tie air purifiers we purchased and couldnt find the part for locally! No worriesIt is a fit , and a much better price!!!

First thing I'll say, the comments stating the fit is a little loose are correct. However, I don't think that's anything out if the ordinary, as putting on the mesh cover over it corrects the fit and covers any tiny gaps. The filter works great, and doesn't have any wierd smell from the factory. It was easy to install. To test it out I directed some smoke into the filter and it came out of the top clean, so I'd say the filter does it's job pretty well. 5 stars because it works well and the fit doesn't effect performance.

I've been needing a filter replacement this is right up my alley Nice price almost comparable quality

Ok. Fit was not great.

Shipped quickly...I've ordered several times and never any issues
