Great filter system
I installed this filter system back in summer of 2019. Took a buddy and I a bit to do because how my basement is setup and what the previous owner did with it. Once I mounted the chassis to the wall, it was relatively straight forward to plumb the water into the filter system with shutoff valves before and after the unit, and a drain valve after. After a year and change of use, this system is still performing amazingly! With the initial set of filters, the middle (charcoal) filter completely blocked the flow and would not allow any flow through. I ran with it removed for a bit, and that was an automatic improvement in my water quality! Chlorine was mostly gone! While this was going on, I contacted Express Water, and they sent me a replacement set immediately. Great company to work with. When I went to install, this new filter worked perfectly. Even more improvement in the water quality! I frankly find it disgusting the amount of sediment that has been trapped. That filter turned DARK BROWN! I can't imagine going without this whole house filter! It says it works up to 80 psi, and I am close to that at 76 psi. No leaks, weeps, or anything. The system is great! One note: If I have one con, it's that the filter housings do not have drain valves on them.

Great filter system
What a difference this made for my whole house. The water filter makes the shower water softer. I feel cleaner when I get out to dry. Clothes are so soft and it removed the well water smell. Great product

This is a great whole house water filter solution!
I installed this as a DIY project using PEX tubing and SharkBites connectors and valves. While this was probably a more expensive option it was something I wanted to try. I did have difficulty connecting into the unit with a 1" metal threaded connectors. I believe this may have caused some damage to the threads on the input side. However, the company worked with me and provided me a replacement for the first stage head at no cost so I was able to repair and install the full unit. Their customer support was incredible to work with. They want the product to be successfully installed and will work with you to make sure you are happy. The one suggestion I would make is if you have to adapt the one inch connector to a three-quarter inch connector, use a PVC 1" to 3/4" threaded connector and install it into both ends first. This way if you have any problems you just replace the pvc connector, not the full first stage head. While this was it doable installation, it required some thought and a little bit of plumbing experience to put it together. Even hiring a plumber to install this would be worth doing if you are not comfortable with this kind of work. In the end, I am extremely happy with this product. It works well, doesn't impact the flow rate of my well water, and my water tastes great. I no longer have to worry about putting filters on every sink in my house. They have a great product here for a reasonable price. Other contractors wanted to come in and install similar systems four four times as much. If you are a little handy or can have someone install this, it is well worth the purchase price.

Good Quality user friendly filter
Good filter unit, brought my radon levels down from 4000 pCi/L to 750 pCi/L after one month of use. I have installed two of these units. One had some defective pressure gauges, the other was fine. It is good quality but not the most robust. Easy to install and maintain. I would recommend the unit. It is not recommended to use with radon levels above 6,000 as it accumulates radiation will give off radioactive material.

Didnt know my water was this bad
We are on city water. We usually drink filtered water or bottled water but we bathe and launder our clothes on tap. About a year ago i started developing a rash that spread over my arms and legs and back. My wife also noticed really itchy skin and red spots. After much diet adjustment and some dermatologist visits we decided to see if our water was the problem. We dont have a water softener and we do have hard water. A cheap water test didnt show anything too concerning except an elevated chlorine marker, but still within normal range. I researched water filters and decided on this for its relatively low initial cost. Install was easy, tho buying the sharkbite connections was expensive as i setup a bypass. I used a lot of teflon tape and a 1inch male to male brass nipple that connected to a 1inch to 3/4 sharkbite water softener hose, which then connects to 3/4 pex. I check it daily for leaks and havent noticed any. I also put a leak detector in the area to alert us if something happens. The unit is bigger than the pictures suggest and it feels very well made. I attached pictures of day 1 vs day 4 and theres significant discoloration of the sediment filter after only 4 days. We also have noticed greatly improved skin after only a few days. I greatly believe that what goes in our body has a huge effect on our health i just never considered that our cities water was bad enough to cause such dramatic symptoms. The filters are going to run about $100-$125 a year but we were already paying 50-80 just for fridge filters and this does the whole house. It sucks that we have to have that expense considering how much we pay for water supply but i wouldnt be surprised if more health issues are due to something we take for granted like water whether its Overtreatment or undertreatment.

Great filter system! Easy installation
This filter system is a beast! Came well packaged and completely assembled. Installed this ahead of a new water softener at the same time. Using copper and sharkbite fittings, installation was easy and quick. Wrapped the 1 inch fittings with about 10-12 wraps of tape and had zero leaks on the first try. All of the pressure gauges worked right out of the box without any modifications. This system will prolong the life of my new water softener and the difference is noticable aready to the water quality just three days in. Installed it on the floor, if going to mount on wall make sure it is mounted to the studs, a backer board, or concrete with good hardware. Very heavy even without water in the housings, well built. Would purchase again and suggest it to those that want cleaner water in their home.

Cet équipement de Express water a été très facile à installer. Il est certain qu'une plomberie en PEX est un jeu d'enfant. Ce système me coûte beaucoup moins cher que ce que voulait me vendre le commerce de pompes local. Mon problème d'odeur de souffre et de goût de sel en raison de mon autre équipement ont été complètement réglé. Je suis donc pleinement satisfait et après neuf mois d'utilisation, je n'ai pas encore changé les filtres. Je pense le faire dans trois ou quatre mois.

Je m’alimente en eau d’un puit artésien et l’odeur d’œufs pourri était vraiment insupportable. J’étais septique au rebut que ce système la règlerait mon problème mais non c’est incroyable, plus d’odeurs du tout, plus de trace de fer non plus. Je suis vraiment content de mon achat. Je recommande sérieusement.

Excellent system!!! Our municipal water is almost undrinkable due to the chlorine levels, after installing this our water tastes amazing!! We also paired this system with a 100 and a 50 micron sediment spin down filter and UV Sterilizer.

I live on an acreage and the water has so much rust that whites are now brown. In only a few days the water is clear and good tasting. It was not hard to install and aside from removing the old lines and components. The filter was very simple to install
