Kinetico vs Culligan sediment filter
I am putting in a sediment filter in my house, dual gradient density cartridge. I have quotes from both Kinetico and Culligan, with Kinetico being 50% more (several hundred dollars). It appears to me from the literature that both use Pentek filtration/filters. I am pretty sure both are just the "big blue" filter housing.
Is there a reason to spend more ? Are there different types of big blue housing ? (the inlet sizes and dimensions are the same)
