Great prices and customer service Review by CB
Needed sediment filters that fit Culligan and were cheaper. Discount filters was very helpful in recommending the right ones. (Posted on 6/2/13)
Great Price Great Quality Review by Seesiso
After 2 years of having the plumbing company replace the filter we started doing it ourselves.After finding this site from the filter we got at the plumbing company who installed our system we ordered our own and saved over 50% in costs. With our system the filter needs to be changed twice a year so (Posted on 7/26/13)
Fantastic Filter Review by JB
This filter really gets the "crud" out of well water and it lasts a long time in service. The only challenge is the first filter change because the weight of the filter and water together will surprise you. After that first time it's a snap. We have been very pleased with the lack of water pressure (Posted on 8/12/13)
