Two Blue Pure 511 Replacement Filters

Genuine Blueair replacement filters for Blue Pure 511. Enhance air quality with these efficient filters. I accidentally purchased the wrong ones for my air purifier. Both are brand new in package One box was opened ( I was hoping I wasn’t wrong in the ones I purchased) but never used at all just put right back into the box I paid $62.54 for both ( as seen in my receipt) Great deal for anyone who uses these purifiers!
