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.

Product is as described

I am running this filter after a water softener on a well. This filter filters out just about all sediment and my water is just about clear. There is still a little tint to it but a lot better than any of the other filters I have tried including the activated carbon filter. The main test will be how long this filter lasts. If I can get three months I will be happy.

Work great

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

My well is in an area with red clay soil and I have always had trouble with the toilet bowls turning a rust color soon after cleaning them. I tried several other filters, but none worked for long. These do work well and last for a few months. There are not nearly as many pleats in the filter as what is shown in the picture. The label says not recommended for use with untreated well water, which I was told was because there are certain bacteria that could be in the water that eat the paper and cause the filter to fail. I must not have them in my water, but I put a screen strainer in the line before it goes into the house just in case.

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

Great transaction. Works perfectly!

These are good for taking a lot of rust particles before my water gets to my water softener

I cant say I noticed much difference in my water after replacing the 50 micron filter with this one because I dont have a big problem with sediment. But I am pleased that the flow rate in the house doesnt seem any different. Its been installed about 2 months now. I expect it wont last as long as the 50 version but if my water is cleaner then its worth it. UPDATE Sept. 17, 2010 I learned something the hard way -- CHANGE THE FILTER REGULARLY! I was waiting for the flow rate to go down as a sign to change this filter but it never decreased. Then a month or two ago I noticed the water starting to smell and it really got pretty bad. Im on a well so wasnt sure if it was the ground water changing but then thought of the filter. Oh my gosh, it was gross. Black & slimy & stinky and the paper had torn so the water was flowing right through with no filtering, hence no pressure loss. This was about 6 months use on a well (no chlorine) which was way way too long at it turned out. Id say the filter should be changed every 2 months.
