Review: Excellent product and amazing customer service! - I couldn't be happier with my experience with iSpring Filters. The product itself is excellent -high quality, well-built, and performs exactly as advertised. What really stood out, though, was the customer service. I had an issue with a filter that malfunctioned, and Nick from iSpring went above and beyond to help. He was responsive, professional, and immediately sent replacement filters without any hassle. That level of support is rare these days and truly appreciated. It's clear that iSpring stands behind their products and genuinely cares about their customers. Thanks again to Nick for making the process smooth and stress-free. I highly recommend iSpring Filters to anyone looking for reliable water filtration and top- tier customer service.
Review: Will Reduce Iron Significantly - I have an absolute ton of iron and salt in my water. I could immediately tell the difference in my water quality. It’s expensive, not as expensive as some other brands but still hard to swallow, but I would say it’s worth it if you struggle with iron. The filter fit into the housing perfectly, and although I still don’t drink it as I have an RO system, my system now and toilets thank me

## Questions & Answers

**Q: We are looking to install this in a seasonal cabin, can this be winterized?**

**Q: I received this whole house filter and one of the cartridges is broken model fc25b. can i get a replacement of this broken cartridge?**
A: allfilters.com 
I used iSpring for a while and then the types of filters ordered was so confusing......and its all made in China.......unlike advertised. So I switched to allfilters....now keep in mind that they don’t send one at a time....but the price difference, the nonconfusion, sent by USPS and customer support won me over. ALL MADE IN THE USA! Allfilters also sells the canisters. When ordering filters go by the size ei: 4 1/2” x 20”

**Q: Do you still need a water softener with this if hardness is 250 ppm?**
A: Hi there, It's optional but would help p[rolong the life of the filters if you install one. We usually recommend a water softener with TDS higher than 700 PPM. Please let us know if you have other concerns. Stay safe!

**Q: What pressure gauge is recommended to install pre and post filter that will work with 3/4" PEX supply line?**
A: I use the one on a spin down pre filter and a 
3/4” shark bite with gauge post filter

### ⭐⭐⭐⭐⭐ Eliminates mold due to iron & manganese in the water
*by P***J on December 1, 2020*

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.
