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

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

Even though not recommended for untreated well water, Ive found this filter to be highly effective. We havent had any problems. They remove much more sediment than the R50-BBSA filter (50 micron). Before switching, washing cars left a noticeable haze on the finish. Using these, that haze is almost gone. Our well supplies two houses, lawns, gardens, and up to 300 head of cattle, so it gets a workout. We use two, plumbed in parallel and getting around 6 weeks before replacement. Once they start to plug the flow rate drops off faster than the R50-BBSA. What I expect with a finer filter.

This was a replacement for my reverse osmosis under-sink filter. It worked perfectly, fit well, and the water tastes great!

Easy to install and does the job.

We have a dug we’ll. Recently we noticed a brownish quality in our water pitchers. Switched to this product and we can see the difference in our crystal clear water. We’ve had one in for about three weeks: still working. Great value for the money.

Fits perfect

I installed this as part of a set which I assembled in an attempt to prevent the buildup of sediment at my washing machine. I am on city water, but it is VERY hard water and I found that I was cleaning out the strainer about once every few weeks. Since installing these items, I have yet to have any issues! The following has been installed for roughly 6 months: Culligan HF-150A 3/4-Inch Whole House Sediment Water Filter, Culligan S1A Level 2 20 Micron Sediment Replacement Cartridge 2 Pack, Culligan SW-2 3/4-Inch Housing Spanner Wrench, Culligan UB-1 Mounting Bracket with Screws. I recommend purchasing all these items for an application such as mine.

The filter worked great on my water system to remove fine particles in the water.

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.

I buy a box of 14 every year for my well. They work great to keep the iron and stuff out of my water supply. We dont drink the well water due to the mineral content but we use the water for everything else. I gave 0 stars for flavor because we dont drink it, not because it doesnt work.
