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

Affordability and so nice to have available.

I have had this water filtration system for a few years but had trouble locally buying replacement filters. Decided to do a google search and found them the cheapest through Amazon with free shipping for orders over $25.00. Great deal and filters work fantastic. Love this whole house water filtration system and would highly recommend this product. Inexpensive to filter out some of the bad stuff found in city water.

great price

If you are using this for well water, please note that right on the packaging when you get it- in the left hand front bottom corner- that it should not be used for untreated well water. I am not sure what else you would use if for. I used this filter years ago when our well was new and I do not remember there being such a warning. One might want to go to the 10 micron or finer size for well water and expect to change it more. I use the 10 micron filter from the same company and like them very much over the years. The 4.5 micron is also good but requires frequent replacement when a well is new or there is a lot of rain. I was hoping to use this as we just put in a new well pump and there is a lot more sludge in a new installation, but I am hesitant to use it now due to the explicit warning.

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.

Good product!

Nicer than buying one at a time, every 2 months.

These work just fine. Im happy with my purchase.

Good item

These filters are the Culligan brand. They are the real thing Saved us a trip to the hardware store. Will buy again if needed.
