Culligan P5-4PK Standard P5 Whole House Premium Water Filter, 8,000 Gallons, Value 4-Pack, White, (Pack of 4), 4 Count

We have a muddy well. These get the dirt out better than 20 micron string-wound filters, for some reason. They say not to use them on water that could potentially have bacterial contamination (some bacteria can eat the cellulose), but we havent had any problems in the several years since we switched. If you are using string-wound, give them a try and judge for yourself.

I have a well and it is high in iron. I have to change it every 30 days. I have tried the others and they only last a day ot two. The stores around here no longer carry them, therefore I am very happy I was able to order them with Amazon.

It did seem odd that a filter that was described on the packaging thus: REDUCES Sediment Rust Scale Dirt Course Sand Sand and then would go on to state: This cellulose cartridge is not recommended for use with untreated well water. One could only wonder what was left to Treat. Called Culligan and a technical rep explained that the statement referencing untreated referred to treatment for bacteria. Apparently if there is bacteria in the water they love cellulose and can rapidly compromise the filter by digesting it. I suggested to the Culligan rep that they be a bit more explicit in their disclaimer and specifically reference treatment for bacteria.

Fits perfect

Culligan water filters. Nothing really to review. Got it on time and on price.

Filter works well for a standard filter. Will buy again.

If you need these, you need them. This is a better price than I’ve found anywhere else

This filter works great, dont buy cheaper filter it is your health. The filter cleans even smaller partials and makes the water taste great.

Good product

like being able to access without searching stores. Used in whole house filtration system
