Review: Quality products - Quality fithers, easy to install
Review: Smell is gone BUT Customer service is TOP KNOTCH. - (Photo shows a bit of a Rube Goldberg setup but I did not want to redo the whole thing. one day maybe...) Based on some extensive research, speaking with John at iSpring and being ignored by my local water treatment company, I ordered a WGB21B 2-Stage Whole House Water Filtration System. The filter I got with the original did remove the smell but only lasted about a week before it returned. I called iSpring again to discuss this with John. He suggested I try this pair of filters: iSpring F2WGB21BKS which he sent to me. Going on 2 weeks and smell is gone. I'm on a 150 ft. well in Central Florida. John has been a great help through this process after dealing with the company that installed my system and dug my well but decided I was no longer worth their time. I would be remiss if I didn't thank Sean (sp) at iSpring who was my initial contact. Whatever they're doing at iSpring for customer service should be the standard.

### ⭐⭐⭐⭐⭐ I buy these regularly, they’re great!
*by S***R on January 6, 2026*

I’ve been using these filters for years with great results. Always fit perfectly, they do a great job of filtering with an odor free result. The flow rate/psi differential stays at ~8 to 10 psi until they need changing out. They last a long time. They never come apart and are simple to replace.
