Great price. Solid product.

Well priced option

Purchased the used like new version and if it is used it didnt show it. Perfect condition. This will be an upgrade for my old 20 x 2.5 housing. Now i can use my old filter for my drinking water line and have longer lasting filters and good flow to the rest of the house.
