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

I use these cartridge filters in my Watts Whole House Filter system. They seem to be a good middle-of-the-road choice as far as microns. The 50 micron filters allow a bit too much sediment through and the 10 micron filter so much they have to be changed often. I use these at home and at my business for a campground bathhouse. The are good quality and inexpensive. Amazon carries them in the Subscribe and Save program which makes is really simple to keep an adequate supply all the time.

Exactly the filer needed

Culligan house filter system

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.

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.

great price

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.

I recommend that no one buy this filter, in fact anything from Culligan. The quality of this product has changed in recent years such that it should be banned from the market. The problem is that the polymer endcaps fail in what is called punching shear. I have used this make and model of filter for 10 years without a single problem until this past year. I purchased a few years supply of filters at once (as I normally do) in 2010 and noticed the endcaps were of a softer material than in the past, but I didnt think much of this since these endcaps also serve as the gaskets. However, upon removal of this filter after using it for a few months (my typical use) I discovered the filter medium and endcaps had collapsed (not disintegrated) like an accordion, while the center core remained straight and at its original length. Closer inspection revealed the endcap had failed in a ring around the point of contact with the filter housing. This is the location where a separate gasket would be on top of the filter. Unfortunately, this did not turn out to be a one-time occurrence. The exact same failure has happened with three subsequent filters, even though I cut the use period in half. Clearly, this whole batch of filters is defective. I have been in contact with the manufacturer (Culligan) over the past few months, and after some limited success at getting them to respond (which was a struggle I might add), they have eventually stopped replying to my emails. This is very poor for public relations. At first, I got several excuses as to why this was not their problem, the most interesting being their claim that the filters I bought were not made by Culligan because they were not purchased directly from Culligan. I informed them that I purchased them from Amazon.com, but they still maintained this argument. I scanned the label on the filter, which clearly shows their logo and contact information (which I had used to contact them) and they became even less responsive. Then I placed the next logical step in the investigation for them to answer, and that is when they ceased to respond altogether. This statement was that if they claim they have no material defects, and since they feel the filter is a counterfeit knock off, then why havent they pursued legal action against the supplier to Amazon? I must conclude that they indeed discovered a material defect with their product and dont wish to continue the discussion for fear of later litigation. I have since researched and found alternate brands of filters (I use both a sediment filter and carbon filter in my system) and will avoid ever using Culligan products again. I will also recommend to anyone that I can to avoid this manufacturer. That is what has compelled me to write this review.

Great filters for hard water including grit; cheaper here online than in store anywhere in town as of the date of this order!

We use this at our home in the mountains. The well water is laden with iron and unless the water is filtered or run consistently, it is not usable. It serves its purpose. If we are only there for a couple days, we remove the filter and I hose each panel off to reuse again. This only works once before the filter paper degrades.
