Seems to be good
Seems to work well. Can't be 100% sure if it works as well as the original, as I have no way to measure small particulates in the air.

Great air filter!
Great filter! So easy to put in & seems to last a long time. The light on the button turns red when it needs to be replaced, so if you forget when you put it in, no worries!

It could be a bit better.
I don’t care what anybody says. It does not quite fit like the OEM, used a little vinyl tape to seal the edges but shouldn’t have too. Not great for non handy people. Not like OEM filter. Mine came with double carbon filtration and thicker filter vents. This one seems lighter and not as thick as the OEM.

OEM?
There are some reviewers asking how this product is comparable to the OEM Blue filter. In comparing the two I can find no difference. The weight, dimensions, and color and density of the gray particle board, and most telling, the manufacturing marks on the molded plastic frame are identical to the OEM filter. It would not be surprising if this filter is made in the same factory as the Blue filter but rebranded as is common for many products coming out of China.
