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

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 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.

These work just fine. Im happy with my purchase.

These are great for the money

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

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

Works good to keep dirt and sediment out of my water.

Always buy the best filter. You wash and cook and drink that water. Why wouldnt you buy the best. Tried the bargain filters and dealt with damaged in shipping, carbon particles that never cleared up and customer service that sucked.

It keeps the small silt and sand from plugging up our on demand water heater.

Fits perfect
