Ordered these as they seemed to be a good price for a two-pack so we ordered 2 (for a total of 4 cartridges). However, we only recieved 2 cartridges. I emailed company and they shipped two additional cartridges out. While the service was fine, I had asked in the email about the product description but the company did not answer. There is a discrepancy. "Part Number RS3-DS12-05 Item Package Quantity 1" and lower it states "RS3-DS12-05 Features: -Set of two replacement cartridges."-I am still confused as to where the error was.. the product description or in shipping. If the price is for one, it is more expensive than locally.

Water filters? We have a couple of whole house filters with cartridges that need replacing about every three months. We use different filter cartridges in each. This is one of them. Our water tastes good. I used to buy these at places like Home Depot, but Amazon beats the prices, especially if you buy enough stuff to get free shipping.
