The really work great also. I have 4 of their systems in my home and they are super efficient. They look great as well. Shipped fast. Packed in original factory boxes.

    RO filter was brand new as advertised, and high quality, as I've purchased from this seller previously. It's a great financial value to utilize home water filtration systems rather than purchasing plastic jugs from the grocery store. Plus it's good for the earth! Filter was well packaged and arrived promptly. Highly recommend these replacement filters and this seller!
