Review on 🔄 1-Year Replacement Prefilter Cartridge Pack Set - iSpring F6CTO for US31 and Standard RO Water Filter Systems by Barbara Evans

Last year I installed an iSpring filter under the sink to replace an aging canister filtration system. Since then I've been impressed and happy with the results and these replacement filters still make me happy with the product choice. It was easy to change them. Just turn off the water in the sink and replace the old items with new ones. The only thing to watch out for is to make sure you get the old washer out of the canister and the new one in place before tightening everything up. The box comes with six filters, enough for a year of filtering. Filters work great, look at the picture where the new filter is on top of the six month old!
