It helped with our water right away

I continuously buy these for our home filtration unit. We have private well water that has a ton of iron in it. Amazon has one of the best prices on this particular filter that Ive found and Im always very pleased with shipping and speed of arrival. Probably due to how much iron I have in my water but this filter never quite lasts as long as it is rated for. I usually change it about every 5-6 weeks when they are rated for around 12. I change it more frequently or I start to see very small amount of residue begin to build of in the toilet and shower heads. As long and they are changed to the month(ish) range Im really pleased with their performance and will continue buying and using them for my home.

easy to use

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

We have a dug we’ll. Recently we noticed a brownish quality in our water pitchers. Switched to this product and we can see the difference in our crystal clear water. We’ve had one in for about three weeks: still working. Great value for the money.

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.

Cleans up the water and catches the rust from the water

I had been having trouble finding the name brand filters for my house and these were the right ones and fit the filter that I have. The price was reasonable also.

I use as a sediment filter in my whole house water filter. Good level of filtration without reducing pressure. Lasts about 4 months in my location. Could go longer. Just depends. Economical enough not to worry about replacement.

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.
