The D-20A and D-20 (older model) are not the same cartridge. Revisions to the D-20A include better intake and outlet channels to create greater water flow. In addition, the D-20A cartridge will not fit the older housing model US-550. Only the US-600A (current model) and US-600 (predecessor model to the US-600A) are compatible with the D-20A.

The filters were exactly as pictured and described. Very easy to order from and fast shipping. Excellent communication. I will definitely be using Allfilters.com again.

Easy to order

By Male in 60s and over from Clearwater, FL on 11/21/2021 11:52:20PM

Everything came delivered to the door ahead of schedule. Ordering was very easy but if I remember correctly there wasn’t a remove from cart button. I like no nonsense ordering and that’s what I got with Allfilters

Hard to find

By Man in 60s and over on 4/24/2020 7:47:32AM

This water filtration filter is hard to find. None of the local hardware or department chains keep it in stock. I found it to be readily available through AllFilters.com when searching on the internet. Ordering was easy, the price was right, and delivery was in a reasonable amount of time. I will consider using AllFilters for all my filter needs.

Good brand, great price, esp. when I don't have to buy so many like the R50 well filter.

Good Basic Fiter For Better Tasting Water

By Man in 60s and over on 6/22/2021 6:05:57PM

For public, already safe to drink water, this helps it taste better. The low filtration allows it to last way beyond it's one year life, however, it still should be changed every year to guarantee the best taste and minimal chance of bacterial contamination. In the past we used the higher filtration type, but they clogged too fast. As long as you are using safe, clean water... these are fine.
