I've purchased three Kenmore RO Systems over the last 10 years, One for our old home, one for our new home, one for our son's home. We are very pleased with the systems. I buy your filters because they are made in the USA.
While these filters were fairly easy to find they totaled nearly 1/3 of the total water osmosis system cost at nearly $50. The center filter was not in the store and sales person could not find online. I couldn't find it online either, but when I got help, she was able to find it. Not only was it expensive, there was a $15 shipping cost and she said she couldn't ship it to the store. Had I known that the filters were so expensive to replace and difficult to find, I would not have made this purchase.
I have not used this item yet, but usually it is reliable. They general don't last more that 6 months, but the area is very hard water.
Glad these are still available even though the nearest Sears to us went out of business. Packed well and shipped in a timely manner.
I was disappointed Sears did not take my points when i bought this item.
