iSpring Whole House Water Filter Cartridge, Iron & Manganese Reducing Water Filter Whole House, 4.5" x 20", Model: FM25B

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.

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 we think it works fine.

The ispring team especially Michelle are really great .You can talk to someone on the phone who is knowledgeable about their products!Very refreshing to actually speak to a human!They quickly helped us with our problems.I highly recommend this company.

I am very pleased with the ispring water filter system. Also pleased with the customer service at ISpring. When IHad a question about the canister Michelle was extremely helpful. I highly recommend this company!

This is a reasonably priced filter with quality and long lasting use. Ease of ordering and quick shipping.

I have some clear water / soluble iron in my water, along with - I'm not really sure what, but my water softener wasn't really able to soften the water (which is 70 before the softener).With this filter, the soluble iron comes out of the water, which isn't an issue at all in my case since I use a 0.5 micron carbon filter after this one, but it is a consideration. With this filter installed, my water softener now does a great job of softening. Softeners are supposed to be able to handle iron at the level mine measures (.3ppm, just enough to stain everything), but somehow mine clogs up and fails to soften without this filter - I used to use a basic sediment filter in front of the carbon filter and the softener wasn't working, but now it works like a champ!
