Have used for some time and always reordered when I needed them.

I like the filters I’m able to order them and get them went I need them. The only problem I had this order was the shipping box was beat up pretty bad and the filter was bent and I had to straighten them out. I think the Shipper needs to think about finding another way to ship them or how to handle them or maybe you need to find another shipper

The product is good and at a reasonable price. Unfortunately the box it came in was crushed in on in side and 2 filters were damaged so gave a lower rating.
