The heart of the best RO system I've owned

Mike. RAugust 2, 2025✓ Verified purchase

This filter does exactly what it is supposed to do as part of the RO500 tankless system. Just make sure to replace it when the system tells you to. Otherwise the waterflow drops significantly. I'm very happy with this system and this filter Read more

Outstanding Customer Support - Thank You Nick

Miriam G MichaelJune 9, 2025

iSpring customer support is outstanding and Nick was exceptional. I came home from a long trip to find my iSpring Reverse Osmosis Water Filter System showing all RED! I got the manual out yet needed more help … I went online and contacted customer support. The reply was quick and after a few email exchanges with Nick I was able to confidently order the products I needed and thanks to Nick’s expertise and patience I’m back in track to drinking healthy water 💦 - thanks Nick!!!

But if a challenge to install but good quality otherwise

CustomerMarch 21, 2025✓ Verified purchase

Why these cannot be easier to install!! They are a bit of a pain and took some time to install and reset the machine. After installation they work well and last a good amount of time. Read more
