· Q & A



For many years our family has enjoyed the RV lifestyle. We presently travel in a motorhome whenever we can get away for a few days. We may find ourselves in Florida, enjoying a resort with all the amenities. Then again, we may hide away in one of the many excellent, back-country, primitive parks where we can enjoy nature.

A concern that we have been dealing with, no matter where we might travel, has been clean, safe water. Today our water could come to our RV via a municipal water source. Tomorrow, we may be 400 miles down the road and discover the water comes from a well, or in some cases, taken from a river or stream. Water quality varies significantly across the country. The water may appear excellent or it may look very poor. The only way we have had to determine water quality was through smell, taste and appearance. The real issue is that water may look bad, taste bad or even smell horrible, but it may still be safe. Conversely, none of these physical indicators may be present but the water may not be safe. Of course, when your first cup of coffee in the morning tastes like fish, it drives this concern even more.

It is a fact that the water supply in the United States is becoming more polluted every day. The contaminants can be generally classified in to three categories. They are inorganic, organic and biological. Disregarding the health dangers for a moment, some of these contaminants will harm the plumbing and appliances in your RV, leading to premature failure.

Now, this is not to imply that water available to us is always unsafe. To the contrary, most water is still safe, albeit possibly unpleasant. But if we are going to clean the water of aesthetically objectionable components, why not at the same time reduce harmful contaminants that could be present. We have developed a filtration system that delivers clean, wholesome water to our entire RV in unlimited quantity. Wherever we may travel, we are assured of safe, consistent, very high quality water. Allow me to explain.

Starting with our first RV, we have been concerned about water quality. Our first filter was one we found in the local home improvement store. It was a 20 micron filter and, unknown to us due to ignorance, did little to improve the water except take out the large chunks. The more we studied the issue of rendering water safe and palatable, the more we realized that it is a very complex proposition.

There are several methods available to process water. The most common are filtration, chemical disinfection, reverse osmosis, boiling, distillation, ozonation and ultraviolet radiation (UV). Of course, there is always bottled water.
There are a few other methods that may help, such as ion exchange, magnetic and altered water.

The ideal process system has to be portable, easy to use, reliable and not require electricity. In our research we kept coming back to filters. There are hundreds of companies that offer filters. Some are good, while others are worthless. The key to understanding the effectiveness of any filter is what contaminants it can capture. There are three basic concepts employed to capture contaminates. The first is “mechanical” filtration. In simple terms, the “Pass/No Pass” ability of a filter is determined by the pore size of the filtering medium. This pore size is measured in microns. One micron is equal to .00003937 inches. The smaller the pore size, the more contaminants the filter will capture. For instance, the pore size to screen out Crytosporidium and Giardia is in the order of 4 to 5 microns. Cholera, Typhoid and other bacteria require filtering down to 1 micron or maybe less. The human eye is not capable of seeing anything much smaller than 50 microns. Another reference to this micro-world is the period at the end of this sentence. It is roughly 500 microns in size. The diameter of a human hair is approximately 100 microns. Mechanical filtering is very effective for capturing contaminants larger than the filter pore size. Smaller contaminants will pass through the filter and show up at your tap. A few of the filters available today may rely on “adsorption” to capture contaminants. Adsorption works on the principal that opposites attract. If there is a contaminant that carries a negative electrical potential and it comes in contact with a positive potential in the filter media, they will bond. If the filter media is stable, it becomes a permanent bond. Contaminants captured through adsorption may be released in some situations. For instance, if the filter media is sensitive to temperature changes or if the pH of the water exceeds a certain limit, the filter media may release contaminants. Adsorption allows a filter to capture contaminants significantly smaller than the filters mechanical pore size. The third method of contaminant removal actually is a conversion process, where the offending contaminant is changed into a non-offending component at the molecular level. The most common material used in this process is KDF, which is an acronym for a media that employs dissimilar metals to provide an “oxidation/reduction” process. This process can be effective but may alter the taste to an objectionable level.

It is difficult and expensive to produce a filter element that is effective down to the contaminant size we need. That is why the less expensive filtering methods just do not work. A big concern for any filter is “breakthrough”. If the filter media is poorly designed it may rupture and spill all of those captured contaminants into your water system.

After many years of studying this issue and trying a serious number of filters, we developed a very effective filtration method. We use two filters in tandem with the first filter acting as a very high quality prefilter for the second filter. Our prefilter is so effective it can actually remove dye that is suspended in water. This filter has an average pore size of approximately 2 microns, but has very unique electropositive properties that, through adsorption, allow it to capture much smaller contaminants in the form of particles. This includes an efficient reduction of microorganisms including viruses, bacteria and cysts. Through adsorption, it is capable of removing contaminants down to .03 microns in size or even smaller. This can include colloidal particles 25 nanometers or less in size.

We then pass the water through an extruded, activated, carbon block filter that is superior in removing chlorine, odor and other soluble contaminants. These contaminants are invisible to the prefilter as they are in solution and not in a particle form. The carbon block filter media also has a high specificity for metals, turbidity and biological contaminants.

This process delivers clean, sweet tasting water to the entire RV. The good news is that the dissolved minerals our bodies need are allowed to pass. This is a “win-win” situation. We remove the bad stuff while retaining the good things in water. We use our system as a “whole house” filter, thus providing good water for use throughout the RV, not just at the kitchen sink. The RV water pump and associated plumbing benefit from this as well.

Now on to another subject. You probably do not want to know what may right now be living and thriving in your RV water tank and plumbing. Without safeguards, we provide a very good environment for all kinds of contaminants to flourish unless we take action to prevent it. It is important for you to regularly sterilize the water system in your RV no matter how you may choose to process water. This is not difficult and is explained in the “Cleaning The RV Water System” section of this web site. Please, if nothing else, do this procedure. It is also very important to store only chlorinated water in the fresh water supply tank. Water contained in the supply tank that is not chlorinated can very easily be re-contaminated. Take a look at the section on chlorinating and storing water in your RV. We suggest that chlorinated tank water be used for everything but drinking while traveling between destinations and when a water supply is not available such as when dry camping. When we find ourselves in this situation, we make sure we have plenty of filtered drinking water we have processed and stored in clean gallon containers, filled prior to departure. The procedure we use can be found on this website under “Bottling and Storing Water”. This water is used for drinking purposes while traveling and dry camping. When parked and hooked up to a water supply, we bypass the water storage tank and feed water directly into the RV through the RVF-1 filter system.

As you go through this web site, I know you are going to groan about the amount of effort it appears to require to do everything recommended. Do not despair. First, the recommendations here are ones we all should be following anyway. Second, once you have done the procedures, you will find that they really are not that demanding.

There are thousands of web sites, books and articles readily available that discuss water and contaminants. Check out the web sites presented below. Also, do a web search for “clean water” or “water contaminants”. Some of these sites may belong to our competition but they have important things to say and you may want to know. You will gain a better understanding of the RV water problem and can then make an informed decision on what to do.

We decided to start a business and offer the RVF-1 filtration system to our fellow RVers. Our only product is a filtration system specifically designed and built to provide you with safe, great tasting water in your RV. Take some time to review the rest of this web site. Compare our system with other available filter systems. You will conclude that this is the most effective method to clean your RV water and make it available at every faucet. When you are ready to order, use the order form on this web site or call us.
