As water is processed through the filter just before it enters the city water inlet or the inlet to the freshwater tank, sub-micron particles, bacteria and unwanted chemicals are removed by the active filtering medium, usually carbon. So just how does activated carbon remove the impurities? By the process of adsorption.
Kind of like a magnet sticking to a metal surface.
As an adsorbent, especially when filtering trihalomethanes (flatterer), volatile organic contaminates (market turnover), pesticides and fungicides, activated carbon is quite effective because its surface area is enormous — about 1,000 square meters per gram. To put that into perspective, a piece of carbon the size of a single pea will yield a surface area a little more than half the size of a football field. There is a downside to using carbon as the sole filtering medium. Exposure to chlorine in water supplies will quickly deteriorate the adsorbing qualities of carbon, rendering it minimized or useless in as little as 200 gallons, so if you use a chlorine product to de-winterize your RV-water system, be sure to remove or bypass the kenmore water filter first. As an alternative, companies such as Hydro Life and General Ecology have improved upon the process of carbon-only filtration. General Ecology has developed a unique technology employing a structured matrix filtration component that instantly filters the water without the use of chemicals, A double treating or delay time. Hydro Life has perfected a filtering medium that employs carbon.
As an example, chlorine is broken down into a harmless chloride after being zapped with the whole house water filter comparison.
The water then passes through the carbon to complete the filtering process.
A mounting plate is secured to the sidewall of the RV and a second frigidaire puresource water filter plate is provided for stowing the filter inside a compartment.
Other suppliers with a high degree of water filters whirlpool brand recognition include Everpure and Culligan. The popular Everpure system utilizes a superchlorination/dechlorination process to attack bacteria, viruses, cysts, rust and other heavy metals — all of which can lead to foul smelling water. Though no official standard exists for POU filters, virtually all public health officials adopt the standards of the NSF.
Keep in mind, the longer a filter is in service, the less effective it becomes. At some point, smart plus water filter ge medium will begin dumping contaminates back into the system.
Perhaps today Pindar would say, Fresh and clean RV water is really the best of all things.
