iSpring FP25B High-Capacity 20” x 4.5” Sediment Water Filter Cartridge, 5 Micron Replacement

I purchased an iSpring wall mounted three stage (canister) whole house water filtration system several years ago to replace a dual tank floor mounted system that took up too much room and did not back flush properly and could not deliver quality water results. The iSpring system takes up very little wall space and maintenance is easy, simply changing the three filters yearly based on our water usage. Customer service was great with Nick giving me sound advice regarding installation. A couple of years later he gave me good advice as to the use a heat gun to loosen tanks when I had overtightened two canisters. I recently learned that Nick is still providing customer service when I had a question regarding an order for replacement filters.We are serviced by a small water utility company which has pure water, but the water has high levels of sand and sometimes high levels of chlorine. The 5-micron sediment filter removes most of the sand and two CTO carbon block filters do a great job removing chlorine and any remaining sand. We do experience water line breakage occasionally which can introduce large amounts of sediment into the lines which is a health hazard and can damage water heaters, dish washers, and washing machines leading to premature failure. This is another reason to install a whole house system instead of point of source filters for sinks and lavatories. I do find the iSpring replacement filters high quality and reasonably priced particularly when purchased in cases of four like my recent order.Merlin

iSpring products are terrific and I could not be happier with my water quality. I have had my system running flawlessly since 2017. Recently, I had a problem with a low flow rate on a newly installed filter. I contacted iSpring customer service and communicated with Julius. What a pleasure to receive such a prompt and courteous response. He understood the problem and arranged to ship a replacement. They have great products and it’s reassuring to know that they stand behind them.

Great filters at a good price. Customer service is excellent, and they definitely stand by their product.

Good filter. Feeling like 3ppm is a bit high for what it can take but definitely helps.

These are great. I have a three filter system and have these FC25B Carbon filters in all of them. I replaced a big, non-serviceable 4ft whole-house carbon filter tank with this system because my water is so bad that the carbon filter needs to be replaced periodically, and the "lifetime" tank wasn't a good solution. NOTE: Sean in customer service has been especially helpful with my filter needs. THANKS!

This company has amazing customer service, especially Sean over there. The equipment works very well most of the time, and when it does not, they immediately rectify the situation. A great value all around.

Filter does an excellent job with my metals and the sulfur smell. I've been using the filter for 3 yrs and had a problem for the first time this year. The iSpring team, thanks Edwin, did a great job at resolving my issue quickly. I just purchased a new strainer to accompany this filter, it's an iSpring too. They are my go to for filtration.

I love these filters. I run my whole house system on them and their sediment spin down solution. Michele with 1 L at iSpring was great at walking me through the setup and solutions.
