The filter was listed on your website as a suitable replacement for a discontinued item. It is not sized correctly and does not fit the system as stated. Waste of time and money.

I have a problem swallowing regular tap water. It causes me to choke. I can drink an entire glass of water with your filter and not have the pain or choking. The only problem I've been having is being able to find them in the stores in our area. We used to be able to purchase them at Walmart. Thank you for such a wonderful product that works.

These are fantastic. We have drops that we put into a glass of water that tells us how much chlorine is in the water. We tested our water and it was yellow with chlorine. With the new filter. the water is crystal clear. We have been useing these filters for a few years and won't even consider another brand.
