Hi All, I just recently installed a whole house water filter system with a big blue 4.5 x 20 filter and a prefilter sand filter that's flush able.

My question is does anyone have a good online source for the replacement filter for the big blue. I looked and wow there are many ...but who is reliable and won't rip me off. just looking for a good sediment filter as I am on well water.

Any thoughts as to pleated vs non pleated for the filter?

Thanks
