iSpringWGB21B 2-Stage Whole House Water Filtration System with 3/4 inch Push-Fit Braided Stainless Steel Hose Connectors and Ball Valve

We have horrible water where we live and after some research decided on the iSpring 2-stage filter system, which turned out to be a great choice for us. My wife and I are not plumbers and have very little plumbing experience but decided to do the install on our own. Our home is a newly built house and has Pex waterlines, which we had never worked with before. A little more research and we decided to use Shark-Bite connectors. Even though they are a little expensive, they looked the easiest to install for novice plumbers and matched the connectors that came with the filtration system. We took our time to make sure we had clean, even cuts on the Pex and used the Pex tool to make sure it was a smooth surface so we wouldn't have any leaks. Overall it took us about 4 hours to install the system. When it was installed, we were able to charge the system and were happy to have no leaks once it was pressurized. The happiness didn't last long as we quickly noticed the household water pressure dropped to basically zero. We thought maybe we installed something incorrectly, so we took out both filters and ran the system, and the pressure was normal. We then installed just the sediment filter, and the pressure was still normal. After installing the carbon filter, the pressure again dropped to basically zero. I did a little more research and saw online that carbon-block filters can cause a huge reduction in water pressure and that it might be better to use a granulated carbon filter instead, which I found really frustrating, and I wished I would have looked into that ahead of time. The next day I called iSpring customer service to tell them about my issue. The customer service agent was super nice and said sometimes the carbon filter can be blocked and that he would send out a new one and hopefully it would resolve the issue. I was sceptical but had nothing to lose at that point. We ran the system with only the sediment filter installed for a few days with no issues, and once the new carbon filter arrived as promised we installed it. We charged the system and had full water pressure throughout the house, and everything has been running 100% perfectly. The filters come sealed in plastic, and even though the filters had the same part number, the new one had a bigger/different label. We're not sure if the first filter was from a bad lot or if they redesigned something to make them work better. I'll be ordering some additional filters and will make sure they're the ones with the newer label.I'm giving the system 5 stars not only because I think it turned out to be a great product and easy to install but also because of the great customer service. They actually answer the phone and then sent a the new filter as soon as I described the issue.

I chose this filter system because my main concern with my water was chlorine and other pesticides when showering, washing hands, brushing teeth or washing cars. We have a separate under-sink 3-stage filter for drinking water that also removes heavy metals. Anyway, I was impressed by the 15 GPM rating on this item. Installation was a breeze with the included braided hoses. I used pex pipe and fittings that added another $75 in parts for my setup. After installation, I literally had no drop in water pressure! My incoming pressure usually hovers unregulated at just under 80 psi which is about the maximum you want for a residential application. Mostly it’s between 75-80 but on very rare occasions it may go up to 90 psi. According to the label on the filter canister it says it’s maximum operating pressure is 90 psi so I guess that saves me adding a regulator that would have limited me to 70 psi. I have to say I love the strong water flow that comes with 80 psi water. The largest GPM user I have is my water sprinkler, and after testing it there was no reduction in the distance it could spray. And immediately, we noticed no more smell from our faucet water. There was no aftertaste when rinsing after brushing. Also, filling the bathtub no longer smelled like we were at a pool. This item works just as it advertised. Couldn’t be happier for the price. Would recommend to everyone who doesn’t drink straight from the tap. If you plan on drinking from the tap, consider a 3-stage unit.

So, here's my final review. We had a mix up when the product initially shipped. I got the wrong sized hoses with my order. Nick at iSpring was quick to send me out the correct ones. They arrived quickly and I finally installed my system. I am thrilled to report that the system works flawlessly and I am noticing no significant drop in water pressure (we have well water). Nick was great to deal with, and I will admit that initially I was unnecessarily irritated about the hoses. He was very professional from the beginning. Very pleased with the system and the US based support. Highly recommend this system! I will try to remember to update when the system gets its first filter changes.One Year Update: I've replaced the filters twice. Never had issues with loss of pressure. The sediment filter captures a TON of gunk. Carbon filter eliminates smell (the difference in smell from the incoming line/sediment cartridge and what comes out of our faucet is night and day difference). Have been nothing but pleased. Highly recommend!

On initial purchase I did have an issue with this product. It happens. In these types of circumstances what matters next is how the company handles to problem. iSpring was quick to reply to my ticket created on their website. They provided a needed replacement part in a few days without hesitation. As a real estate agent, people ask me all the time to recommend products and services. Well, here's one of those companies that gets my thumbs up. If you are looking for a water filtration system for your home that is easy to install and backed by a reputable company, I highly recommend iSpring.

I recently purchased a new home and the water was AWFUL! It didn't rinse the soap/shampoo off and left residue on skin. This was finally installed last week and has made a TREMENDOUS difference. The 2+ months I had to deal with the terrible water was over at last. I thank God!!
