Happy of the purchase
I installed it about 2 weeks ago. We hired the professional to hook up for us because I am not so handy guy. He has to remove the old RO system, and installed it. Everything went well, except the screw( to tighten the tape)was thereaded. The part was cheap. Luckily we had the spare one for the guy to tighten the tape to finish the installation. The water pressure is ok. Everything is alright. We taste the water differently compared to our RO system. We are happy that we got rid of the tank now and have more space in our cabinet. Thank you, Ecopure! Keep the good work, and improve the cheap screw quality.

    I bought this to replace my PUR water filter that would not fit on my new kitchen faucet. I had a professional plumber install it and one of the components would not thread with the washer included so he had to remove it and use pipe-dope to prevent leaking; if that had not worked he would have had to buy a new brass fitting to replace the component. Also, the faucet housing that holds the "timer" battery is plastic even though the top of the faucet is chrome. The water taste when refrigerated is just okay but I was really disappointed with the taste of the water at room temp, which is why I am only giving this system 3 stars. The taste of the water from my PUR system was incredible and this does not even come close.

    This is just what I needed!
    I ordered this system because I believe that tap water is not a healthy option to use for drinking. So then why is it a good option to cook or wash your vegetables in? I like this system because it has three filtration tubs. Which are easy to change without having to turn off the water! the installation is easy to configure, however I would recommend that you use a pex cutting tool. Be careful not to crimp the line. I added a picture to show how I had to make the pex line loop around the cold water line then go into the unit. If you make a mistake if you push the pex into the connection and hold down the outer ring, the line will pop right out!

    This water filtration system is so easy to install. I love that it has three good sized filters and I feel that my tap water is so much safer and better tasting. The filters themselves are extremely easy to replace once they have fully done their job. That should take about 6 months with regular use. There is a battery operated light on the faucet base that will let you know when the six months is over and you should replace the filters. The kit is complete with faucet, lines, and great instructions. This is a highly recommended water filtration kit.

    you may need a hole saw
    It comes with a lot of parts packed in a box. No packing materials to protect it from damage in shipping. The instructions are good and seem easy to read to me. A few things before getting the unit. 1] you need to have space under the sink you mount it at for the filter unit. 2] this has its own faucet to dispense the cold drinking water, so you have to have a place to mount it on the sink or counter top. It is not made to use your existing faucet. This means being able to cut a hole to mount it and having the room to mount it as well. 3] It does have a water tap, it is installed in between the cold water supply line and your existing faucet. It does have its own water lines included, but you will need a hole saw to mount its dedicated faucet unless you all ready have a suitable hole you plan to mount it in. It is a nice unit so if your up for a little work, it is worth it in the end.

    MADE IN USA - Great tasting water and it only takes a few minutes to install
    EcoPure Water Purifier Under Sink Drinking Water Filtration System Model # ECOP40 Internet #301529559 MADE IN USA - Great tasting water and it only takes a few minutes to install The claim is that this system will delivers bottled water quality drinking water. The key to that is what will the filter TAKES OUT of your water. It is NSF certified and will reduce or remove more than 58 contaminants including: sediment, chlorine taste and odor, cysts, lead, bacteria and virus, pharmaceuticals, common insecticides, pesticides, herbicides, industrial solvents and chemicals such as atrazine, benzene and lindane. And exceeds the EPA standard for reduction of greater than 99.9% of bacteria, viruses and cysts. And what the filter KEEPS IN your water, retains minerals in your water for improved taste. There are two white foam plugs in the filter system that must be removed before installation. When I removed mine, I found that it had been pressurized, so if it hisses or pops that is alright. NOTE: When you first fire up your filtration system, you may see milky water coming out. That is normal and is caused by the air in the filters being purged. It will disappear in a few minutes. This system includes an auto-shutoff feature so that when you filters reach end of life and are no longer providing adequate filtration, the system shuts off. The filter change reminder light tells you when to change your filters. See pictures. Text ECOPURE to 444999 to sign up for filter change reminders. No need to shut off the water, no need for tools, no mess filter change takes less than a minute - just twist off the old filters and twist on the new filters. 1-year manufacturer warranty on parts BPA free Those are the PROs and now for the Con: I found that they used very flimsy toggle bolts to hold the faucet to the counter. When I tried to tighten down the faucet, the toggle bolts exploded. I solved the problem by replacing the toggle bolts with two large washers and two standard nuts. See pictures.

    Delivers nice clean water at your sink
    The EcoPure ECOP40 system installs under the sink and out of the way. You may need to drill a hole from the sink if you do not have an existing under the counter filter system. But all the instructions are included and EcoPure provides technical support if you need it. It is a 3-stage filtration system which is 16" tall and 14" wide for all 3 filters. And the filters twist off making them easy to replace. Municipal water infrastructures in out country are getting old and some are latterly crumbling apart bring more and more contaminates into our homes. Unless you want the expense of bottled water (which can be very expensive for a family) this purification system is a great solution

    Excellent solution to bad tasting and smelly city water
    I am reviewing the ECOPURE under counter water filter system. The city water in my area tastes terrible. It does not smell all that good either. I have used the screw-on the faucet kind of filters in the past but they don’t look that good nor to they fit the new flexible spout faucet I have. So when I saw this filter system I had to try it. I am SO happy I did. This was so easy to install. Everything is included in the package for a standard installation. I had the unit installed in less than 30 min. I suppose now that I know how to do it I could do a second one in half that time. It was that easy. The base of the unit screws to the back wall under the sink, 2 screws. The manual states that the base can be installed in any location. If a more distant location is used then additional tubing would need to be purchased. The two plumbing fittings on the base are color coded, Blue and Yellow. The faucet that comes with the unit has the Blue tube connected to it. All one needs to do it cut this line to length and push into the Blue fitting on the filter base. There is a ‘tee’ fitting that fits between the present cold water line that goes to the faucet. Simply remove cold water supply line from the supply valve side, install ‘Tee’ fitting, and replace cold water supply line to faucet. This might be where some people will have an issue if they do not have a standard fill line hose. If that happens then an adapter of some sort would be required. Mine was a standard fitting so the ‘Tee’ threaded on no problems. A section of Yellow tubing comes with the unit that simply presses into the open part of this ‘Tee’. The other end presses into the input 'Yellow’ side of the filter housing. That is it. Turn the water back on, check for leaks, flush the unit for 10 minutes. Then drink some much better tasting water without the chemical smells from the past. The filters are rated to last 6 months or 350 gallons. The manual states that the unit will stop passing water when a filter is exhausted. There is also an electronic timer in the base of the faucet that will flash after 6 months to remind the user it is time to replace the filters. The timer is powered by a ‘coin’ sized battery that comes with the product. The battery is installed by removing a screw on the right side of the faucet base. In my installation that side is blocked so I’m not sure how easy it will be to replace. It is not needed to use the system so I will probably not use it and put the replacement date in my smartphone. I absolutely recommend this unit to people that want to get drinking water without the need to spend money to buy it at the store.

    So simple
    The Ecopure model ECOP40 is so much easier to install than the big name system it is replacing. Start to finish took about 30 minutes. Pros: Simple install Filter replace indicator light No holding tank occupying precious real estate under the sink No need to tap into the drain line No wasted water when filtering Filters unscrew very easily And most important of all, my tap water tastes great Cons: Pex connections (some plumbers like them but I don't trust it. I've seen them get knocked loose) Difficulty threading the plastic water supply fitting to the existing metal water line and shutoff Faucet feels cheap to the touch Limited availability for the filters make me wonder what will happen if Home Depot stops selling them Overall I recommend this system.

    Clean water, happy family!
    This water purifier is the perfect solution for a household that drinks a lot of water. The municipal water supply has a lot of contaminants. With this filter, we can stop buying water bottles and save a lot of money. It has a great flow. I measured it filling up 2 cups of water in 11 seconds. It is easy to install for someone like myself that has no plumbing experience. It looks great on my countertop. It also has an led indicator for filter replacement. Make sure you hire someone to cut the hole in your countertop (you only get one chance to get that right!).
