6 Stage NSF Certified Under Sink Reverse Osmosis Drinking Water Filter System w/ Brushed Nickel Faucet

This was just what i needed for the job. Very easy to set up and worked great.

Easy simple to install. Just follow instructions.

The installation video is well done. Initially, the diverter piece was leaking (even after taping the threads). I contacted iSpring support and Francis sent a replacement part. Thank you, Francis!

We buy ispring wherever possible for our clients. They always ship multiple extra parts for maintenance and the workmanship so far has been flawless. Can't recommend these guys more.

I replaced an older AquaSource RO system with this 6-stage iSpring one. It came with a nice quality non air gap faucet (1-line) that was a lot easier to install than my older air-gap (3-line) faucet. If you drill a hole through the countertop for the faucet make sure you don't drill the hole to big and avoid the sink clips underneath (to include giving yourself enough room for the required washer and plastic holding screw) or else your faucet will tighten on an angle. System came with instructions and all required parts (plus some extra) except teflon tape. I recommend using the YouTube video to install it. I found numerous videos available that really did help. Installation took me about an 1 1/2 because I could not use the drain saddle and had to devise a way to drain the system. I ended up using a 1/2" screw by 1/8" quick connector (came with extra parts). I drilled a 1/2" hole into the drain (not the trap) and screwed it in using a little sealant. Ended up being very tight but put some silicone over the edges just for security to prevent any leakage. After the RO was fully installed I turned the system on as described in the instructions and found 4 leaks (all my fault). #1. Make sure when you screw the pressure tank control connection on you look at the black o-ring and ensure it is seated correctly and use a generous amount of teflon tape on the screw top. #2-4. Make sure when you put the 1/8" plastic tubes in the connectors you gently press all the way in to hear almost like a click. Then ensure ALL connections have the retainer clips installed (comes with extras if needed). Once I repaired those items it was perfect with a real nice strong flow.

I've been using this filter for a long time in my home country, so when I found this filter in the US, I was very happy! For healthy drinking and cooking, I don't know of a more effective filter.

I purchased this after a toxic train derailment in my state because of concerns of the drinking water being contaminated. After looking into water quality reports in the area, I realized I should have purchased one of these years ago. I have been using it for about 4 months now and even my skin has cleared up.
