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

The S1A is a good filter, but be careful when ordering. If you select the 4-pk, you will be ordering a different filter due to a system glitch and may not notice - based on first hand experience.

Easy to install, seems to be doing the intended job.

after finding out that bleach would only make the problem worse, we started using this household filter to keep our clothes and drinking water nice and clean. And now, we can even drink the water from the tap!! Plus, its alot cheaper than installing a whole house filter. quite the miracle worker if you ask me!!! If you have liquid iron in your water like we do, try this one out!! you WILL be happy!

Value for the money and easy install

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.

Worked as it should no issues much clearer water

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

I purchased this product in May 2013 to filter very fine sediments from my water well, which I use for my fogging system in the farm. At the same time, we use it also for our water consumption, so it is important to remove scale, silt and dirt. Because the fogging nozzles I am using are very sensitive to sediments that are bigger than 10 microns, I used the Culligan CP5-BBS Level 4 Heavy Duty Sediment Cartridge, enclosed in a Culligan HD-950A 1-Inch Outlet/Inlet Heavy Duty Sediment Water Filter Housing, because it filters up to 5 microns. Since then I never had problems with my fogging system. I am very impressed with the result. After 2 years of using it, I decided to write a review. While installing it 2 years ago, I was worried that this product would slow down the water flow rate, much lower than our desired 18-20 gallons per minute, which would then be detrimental to our fogging machine. But it turned out that this product has a high flow rate. Today, I am buying another 4 of this cartridge, good for another year of supply. I would definitely recommend this product together with the Culligan HD-950A water filter housing to anyone who is using a fogging system for greenhouse plants, and to anyone who has issues with the quality of their water.

Culligan is top notch rated when it comes to water filtration I purchased their whole house filter which in itself is exceptional because it has a bypass. This is One of two choices when we’re talking 5 µm filtration I purchased this to test out mesh versus string. No matter what the larger size is a must when you’re designing and building your own water purification system

Filter cartridge for my “big blue” water filter. We have a lot of iron in our well water. This takes it out. I replace every three months.
