🔍 RONGJU 2 PACK FLT5000 Filter C with 8 PACK Pre Filter: Compatible with AC5000 Series Air Purifiers Review

They fit my Germguardian 5250 but are VERY tight. Be careful during installation as the cardboard frame may bend or break. After installing it seems to work.

fits very tightly (almost didn't fit - the cutout is slightly larger than the original branded filter. Also, it smelled for about 2 days, then finally stopped smelling and cleans now the air good.

My air purifier is listed for this filter. I have two different cars, but the previous filter fits both. It doesn't work well with my Invisiclean and definitely doesn't work well with my Germguardan.

I liked that the extra activated carbon pre-filters were included. The HEPA filter is very dense and not as durable as the original as it has a cardboard base instead of plastic, but it seems to work well.

Cheaper alternative to brand name replacement filters. Fits snugly to the product, pre-filters attach with Velcro. My only complaint is that the sides of the HEPA filter are made out of thin cardboard and not plastic. Other than that, we haven't had any problems so far and it's a much cheaper alternative.

These filters are not original so who knows how well they clean the air. I have no way to check. They are quite thin as they are made out of cardboard and not plastic. they hardly fit either. They are too big and have to be pushed into the cleaner with a lot of force. Eventually I had to die cut it to fit.
