iSpring FP25BX10 20" x 4.5" 5-Micron Universal Sediment Filter Cartridges, Multi-Layer Gradient Design (10 Pack),White

Great filter!!!

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.

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

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.

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.

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!

I retrofitted this iSpring filter & housing into my current whole house water filtration system. My system, prior to the FM25B installation, did a great job of removing particulate & chlorine from my public water but actually exacerbated the mold growth in my sink drains & faucet aerators, shower heads, due to the lack of chlorine. After reading up on this phenomenon I found that the culprit is residual iron & manganese in the water, which w/ the lack of chlorine to counteract the oxidation, actually promotes the growth. Thus the addition of the iSpring iron & manganese filter as the last stage in my system. Voila' , the mold is gone! No pink or brownish/black mold in the sinks, shower, etc. A 2nd benefit is that the water is now also significantly softer. I consulted w/ iSpring customer service rep Francis a couple of times prior to my purchase. He was extremely helpful, filling me in on the filter details, e.g. Fe & Mn particulate size limits. He even recommended that I contact my local water authority to verify what those #s are. FYI - that was a bit of a challenge given that these metals are NOT regulated by FDA guidelines & only measured against "recommendations". Smaller is better obviously because this determines the life of the filter. This is no small concern given the cost of the filter. Replacing it 1-2x per year is financially viable, 1/mo isn't. And finally, given the size of the filter and that it's added to my current system I decided to include a pressure regulator after the last filter stage (see pix) expecting that there'd be a pressure drop that I'd have to accommodate for. In the end, all is good, problem solved & pressure is still very good.
