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

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.

Work great

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

These work just fine. Im happy with my purchase.

I am running this filter after a water softener on a well. This filter filters out just about all sediment and my water is just about clear. There is still a little tint to it but a lot better than any of the other filters I have tried including the activated carbon filter. The main test will be how long this filter lasts. If I can get three months I will be happy.

Cleans up the water and catches the rust from the water

Easy to install and does the job.

if theres much in your water these dont last 2 months or anywhere close but theyre protecting your appliances

Its a water filter for heavy mineral well water. Most people use one a month. Our well water has high rust so we use one a week.
