Compatible For TW30-1810-50 Sears Kenmore UltraFilter ® 500, 625.384750 (#37233557), 550, 625.385750 (7267970), Whirlpool ® Wher 18 (#7266186) reverse osmosis membrane

As the review title states, this RO membrane works well for my aging Kenmore UltraFilter 500 RO system. It is reasonably priced too. Glad RO membranes are still made available for this unit.

Great replacement for a product that is not available from the original supplier anymore. Turned out my main problem was in the RO storage tank...it had lost its air pressure and was an easy fix. But now I’ve got the primary filter like new for several more years.

On the bottom of the item the tube like piece on mine is much shorter that the one I received. It was about an inch longer than mine. Not sure if it would fit because I didn’t want to open the package.

The filters were exactly what we were looking for to replace in our osmosis filter system. With many of the brick and mortar stores no longer available it is so convenient to be able to get quality product online and have it delivered as expected. Thank you

The description said these filters were compatible with Eco Water reverse osmosis drinking systems. The filters looked like it, but when I got them, they were too short and fell off. I did my best to carefully keep them in place, but they still fell out apparently after installing them. Water looks and tastes terrible! Now I have dismantle the whole thing and go directly to Eco Water (which is far away from me) and spend more money to get the right filters. I'm just sick that I fell for this and spent over $100.00 that's hard to come by being on a fixed income. Can't even return them since I tried to use them. The O rings fit perfectly, so no complaints about those.

Since our Sears store has closed I wasn't sure I could get this replacement filter and would have to buy a whole new system. I was very pleased to see that Amazon has it. Very quick service and delivery. The filter is exactly what I needed and has been producing good clean filtered water since I put it in the system.

Moving from one area of the country to another presents a problem in getting used to the "taste" of the new water. We installed a reverse osmosis system, which requires regular replacement of the reverse osmosis membrane and filters. As the system ages, it becomes more difficult to find the correct replacement filters. We always order from this company and have had great success with their products.

works great!
