Breaking it down


Consumer testing shows results. While there are no professional tests of the APEC ROES-50, many consumers have posted results of their own tests showing a significant decrease in total dissolved solids (TDS). APEC claims that its 5-stage reverse osmosis system removes a long list of contaminants. Experts say that reverse osmosis systems are very good at removing small-particulate organic and inorganic compounds as well as odors and colors. User say they saw an immediate improvement in their water quality, both color and taste, as soon as they installed the APEC-50 ROES. The downside is the amount of waste water produced is three gallons to one gallon of filtered water, but many say they reroute the brine water tubing and use that waste water in the garden.

Ease of use

You don't need a plumber for install. Even those who describe themselves as "DIY-challenged" say they were able to install the APEC ROES-50 in a fairly short period of time. We saw some input that it took as long as two hours, but most say it's about one hour. One note: you have to drill a hole in the counter for the faucet. The installation kit comes with everything most people need, but when it doesn't customer service is reported as being unusually helpful in identifying the problem. While the included adaptors don't fit all sinks, we saw no reports of anyone being unable to install it; ultimately, they were able to get the correct adaptor from a local home improvement store. It includes one chrome faucet; other faucet styles and finishes are available as optional purchases.

Durability/cost of ownership

Very affordable RO system. Reverse osmosis water filters can cost thousands of dollars, but APEC is one of the most affordable options, say owners. In addition to the initial cost of the ROES-50, you'll need to replace the three pre-filters every six to 12 months, at a cost of about $75. The ROES-50 is reported as very durable. We saw some comments that the included faucet seems flimsy, but no actual reports of breakage or failure. Although the ROES-50 only comes with a one-year warranty, APEC offers lifetime tech and customer support. The ROES-50 has a tank capacity of four gallons, and a system capacity of 30 to 50 gallons per day, depending upon the specific water pressure in your home, enough, users say, for just about any family size. An optional Icemaker Kit (Est. $21), which filters your refrigerator's water supply, is also available.
