LifeSupplyUSATrue HEPA Filter Replacement Compatible with Blueair All 500/600 Series Purifiers 501, 503, 505, 510, 550E, 555EB, 601, 603, 605, 650E Air Purifier (3-Pack)

Always looking for a less expensive option for the Blue Air filters. Amazon keeps changing the vendors I have purchased from in the past. These are also half the price as OEM and seem to work just as well. Only complaint is that they don't have the little tab to make it easier when removing them from the filter well. Not a big deal.

This is a great product for the Blueair air purifier needing 500/600 filters

I was apprehensive because, like others said, these are cheaper than the blueAir filters, however, they fit PERFECTLY in our blueAir 600 unit and immediately helped. The part that faces out is black, so it blends perfectly with the grills. Nice snug fit, didn't affect any airflow or issues with our unit. Our low setting wasn't working before (probably from the icky and overdue for a replacement OEM filters) and now works perfectly fine! Fall (and Spring) in Texas really kick up the seasonal allergies around here and so far this is helping our purifier work and helping everyone breathe easier. I would definitely buy these again and recommend them to anyone!

Bought these as first time replacement for Blue Air Model 603. Fit perfectly. I can't detect any difference in operation, so I'm pleased so far. Barring any problems down the road, I'll order these again.

I am so thankful that LifeSupplyUSA has the filters for my Bluair air cleaner machine at such a reduced price. I can detect no difference in quality between these filters and the manufacturer ones I used to spend 3 times as much for. I am a customer for life!

exactly what i wanted

These filters are total JUNK!!! They are NOT a Blueair replacement as advertised!They restrict airflow on the 500/600 series units. They look like the real thing until you hold them up to light. They are twice as heavy and are so dense that you can't even see light through them. After I installed them my fan's high speed dropped down to low speed even though the switch was on High. When I put the real more expensive Blueair filters back in, the fan's speed went back to high as my switch shows. I purchased 2 sets of these and had the experience with both Blueair 500/600 units. I've sent them back to Amazon and purchased the REAL Bluefilters.I have to really question these other reviewers sanity to give these 5 stars. I would have given them minus -5 if I could. These are Total Junk and I believe using them knowing that they do restrict the airflow of your expensive Blueair units will hurt your fans motors in the long run.

I was a little hesitant to buy these since there was only one review at the time but I took the plunge. These are half the price of Blueair filters so they have to cut corners somewhere. First, the built-in handles (two finger holes) you get with Bluair are missing. Second, they are about 1/4 inch too short. You won't notice any difference on the sides but when you slide the top one in you'll notice it doesn't lock into place but has a bit of play. Once you put the lid on you won't be able to tell. So fo half price.....HECK YEAH!!!

The media could not be loaded.  The first days it had a particular smell, but after it is gone. They are lightly sub-dimensional. The price is good. I recommend it but manufacturer should review dimensions.

Fitted perfectly my Blueair 600.
