Instructions we easy to fallow

Would Recommend

I bought this R O filter and it was really easy to install, the water tubing that you push in the fittings has blue locking clips, remove them before pushing tubing in, after tubing is in, reinstall locking clips.other than that, it was easy.

many leaks

Would Not Recommend

Don't buy this. it is easy to put together but the components are poorly. made. The connectors leak. I've had the plumber here three times already to fix them. The actual operation of the filters is wonderful. My kettle which used to get crusty white stuff on it is now clean. I know the water is clean but I can't have a leak in my kitchen. Don't buy it.

No-brainer for Iowa residents

Would Recommend

I have a 3 year old and a 2 month old in an area with high nitrates (Iowa). This purchase was a no-brainer. The only hiccup during installation was my lack of plumber's tape, but a few hours and a Menards trip later, we're enjoying pure and healthy water for drinking and cooking.

Excellent filter system

I bought this product through a local heating and plumbing contractor. What an improvement in the quality of our drinking water. The customer rep, iris, was very helpful setting up my warranty.

Time

Would Recommend

It works great. It takes some time before the water comes out, so don’t be panicked when it is first turned on and nothing comes out.Sean sent me this survey.

Great Customer Service

Would Recommend

I recently purchased and installed an iSpring RO water system. I had a problem with the faucet that came with the system leaking, both out of the spout and from between the handle and the faucet body. I contacted iSpring and Sean was very helpful. He quickly sent me a new faucet. I installed the new faucet and everything is working beautifully. I appreciated the great customer service that Sean provided.

Great product, exceptional service!

Would Recommend

This product is outstanding! We loved it so much, we bought three for our home and the kids' homes. Installation is very easy. There are plenty of clear instructions and videos that any homeowner with basic skills will be able to install it. The tools required are minimal. I placed all three in the basement mechanical rooms and ran individual lines directly from the Reverse Osmosis to the provided sink faucet, which looks very nice and of high quality, and the refrigerator water and ice dispense...

Contaminate removal and re-mineralization of RO water

Would Recommend

I have had mine almost 3 yrs. The amount of contaminants in the sediment filter out here in the Phoenix area is insane!

Exceptional service

Would Recommend

I've been using this filteration system for many years and have been very satisfied with the quality. Recently, one of the housings cracked which led to water leak and Sean helped me to replace the entire unit for free. I've installed the new unit and it's working great as before. Thank you Sean and iSpringFilter team!

Great company. Great product

Would Recommend

I've had the unit for 8 months, and it has been superb. The water tastes absolutely fantastic. I had a non-system-related leak, which triggered the stop water mechanism. I called in and got Sean. He was great, explaining how the mechanism worked and how to correct it. He then offered to send me a replacement mechanism free of charge, as I damaged mine during the repair.
