I don't see any difference from the full price of the original Blue Air. Other reviewers have given good photos and I'm so glad I found a cheaper option. After a month of use, this filter does everything the OEM does. I have really severe allergies and asthma so I can tell if this isn't doing the job. Quality and fit are perfect! I'm so glad there is a cheaper filter for my Blue Air 211. I will update if there are any problems but I don't expect them. Will buy again Update April 3, 2021 The filter works great! We haven't encountered any problems. He catches everything that should be. Now that pollen and allergy season is in full swing in the US, it still gives me a sigh of relief! Save your money and you can try it with confidence. This is my experience and I received no discount or compensation for my unbiased review.
