What Is the total cost to replace filters. And average time spam between filter changes

Asked by: Mk
The carbon & sediment filters need to be changed every six months. The third filter is a membrane and should be replaced every 2-5 years. The fourth filter (in line filter) should be replaced once a year.

Question for the manufacturer: It doesn't make sense that this product contains a Prop 65 warning...

Question for the manufacturer: It doesn't make sense that this product contains a Prop 65 warning and cannot be sold in California as a result of chemicals thought to cause cancer or reproductive harm. Is the sale restriction on this model a result of the type of carbon in the filter and if so can it be substituted out for a compliant cartridge (such as the coconut shell variety)?
Asked by: NewsView
Prop65 does not mean a product cannot be sold in the State of California, it simply means the product must carry a warning about certain chemicals that may be present in the product. For more information on Watts compliance with California's Prop65, please visit http://www.watts.com/pages/prop65.asp

Zero-Waste Reverse Osmosis Water Filtration System is rated 3.9 out of 5 by 13.
Rated 4 out of 5 by from Great system This system works great. Fairly easy to install. However, for my install I needed to replace a few fittings because I did not use the supplied faucet as I had a fairly new airgap faucet already that mached my other faucet.

Rated 4 out of 5 by from A good little system I bought this unit about a year ago (time for new filters). It has performed great. It was easy to install (the tubes are all color coded). The waste water hooks up to your hot water system. There is a small pump that runs when the water is being filtered. The pump is very quite. I have never had a problem with pressure or running out of water. (We use a lot of RO water in our humidifier.) No broken parts. No leaks. No complaints.

Rated 1 out of 5 by from Worst of Watts Premier! Bought this to replace my 5 stage Watts Premier R/O. The old unit worked fine, but wasted a lot of water. I remodeled my kitchen, and in the process, thought I would replace my old R/O with a new one since it was quite old and needed new filters anyway. I was going to buy the same unit (even though it was slow like all R/O's but decided on the zero waste for enviromental purposes. Boy was I wrong! This unit has less water pressure and produces about 3 glasses worth of water at a time, then runs dry. I am now going to try a single Culligan (US-EZ-1)filter. I will try to update this.

Rated 5 out of 5 by from love this system We are here only for 5 months a year and have had this system for two years and just starting our third year. We are just now replacing the filters as we only use it for 5 months each year. We have never had a problem with the system and would highly recommend it. We like the fact that we do not waste any water with this system thus saving on water. We have never run out of water and we do use quite a lot of water from the system. Makes good tasting ice cubes.

Rated 5 out of 5 by from Save lots of Water. Estimates, depending on the unit, run from three to six-gallons of waste water for every gallon produced in an RO. We have had this Zero-Waste system for five and a half years and let me tell you, compared to our Culligan unit that we had for ovr ten-years we are saving about between eight and ten-gallons of water a day. The only trouble we have had was because the contractor installed the pressure gauge on the co-op water meter and probably used the setting of the unit out of the box. The motor ran on and on and I was sure I would have to replace the motor before long. I finally got off my dead rear end and checked incoming pressure at the meter one day and it was only 50 PSI. I upped to it 65 PSI and everything was better, toilets flushed better, water softener was more efficient, as was the dishwasher and the RO pump ran and was done in a few minutes. With the price of water going up and with it becoming more scarce, this Zero-Waste RO is perfect.

Rated 5 out of 5 by from Very nice RO system We bought this system three years ago and it runs great. We use it for cooking and drinking all day long and its pressure is very good and constant. The only down side is that I couldn't find replacement filters in the local stores not even in Home Depot where we purchased it. However, I was able to order the filters from the company's website for very reasonable price ($13 per set).

Rated 5 out of 5 by from ALL. THE GOOD, NONE OF THE BAD I replaced an older 4 stage unit because of the water savings. It performs as advertized. It is important to be sure that requirements such as hot water pipe length and water pressure are met. Water that normally would be wasted is stored in the hot water supply pipe. The water in a hot water pipe usually goes down the drain while waiting for hot water at the tap or the cold water faucet would have been used used. If the supply is too short it won't hold enough RO waste and if water pressure is too high the pump may have to work too hard to push the waste up the pipe. This system easily fills my 2 gal. pitcher without fading to a drizzle like my old unit did and the water tastes as pure even though it has less filters. The pump turns on after about a cup of water. I can't hear it unless the cabinet door is open and the house is silent. I researched the unit on line but bought it at Home Depot because it was available locally. It has T-valve adapters that fit at the hot and cold faucet connections so you don't have to pierce any pipes. This is a big improvement over older systems that used self tapping valves that eventually leaked. I've had it for almost a year now and disagree with statements by some that you would be washing your hands in contaminated water (when the water gets warm it's from the water heater so the waste water is down the drain) or that the pump is noisy (my refrigerator is louder). This system is the answer to RO.
