Great filter that fits perfectly in my BlueAir purifier.

This filter replacement was great. It comes packaged very nicely, it has a chip in it so your air purifier knows how long it has left until it needs to be replaced. So far it is the same in that respect to the filter. I have checked it a few times after installation to see if it's getting as dirty and capturing as much as the OEM filter and it seems to be doing pretty well. You could barely tell the difference between this one and the original. The air purifier has a sensor that will kick it up if it detects VOC and other particulate matter. This thing kicks on a lot when I am cooking, what I have noticed between the filters, is that it takes maybe a few minutes longer for my air purifier to go back to green with this filter than the OEM one. It still brings the levels in the space down, but it doesn't filter at the same speed but it gets to the same place after a little bit of time.

much cheaper than the name brand

Not only have Filters gotten ridiculously overpriced these days, but after “Covid” we all know quality has been out the window. This filter fell apart into 2 parts right out of the box. It was hot glued not straight and fell apart from probably sitting in the heat or someone ruined it and tried to fix it and returned it 🤦‍♂️. Going to try wasting my time using a heat gun to re-align it. They should of just used glue instead of hot glue.

I was having trouble getting the filter from the company. I bought my air filter from this was the perfect solution better price faster delivery..
