I understand some posts are opinions and should be verified if you question the content before acting on them. I make an effort to purchase only “quality” American made products from American companies whenever I can, so I wanted further clarification on this subject. I contacted Dr. Ronald Martin of Original WaterPur Water Filters and WaterPur Replacement Water Filters at sales@waterpur.com to inquire about the products KW1 and FR1. The following are my questions and the answers I received:

Thank you for your questions and for forwarding the inaccurate post about our product. Questions like yours allow us to correct misconceptions and to remedy the untruths that are posted, either by malice of competitors or a misunderstanding of information.

1) MADE IN THE USA? Our FR1 line is made in Phoenix, AZ.

2) IS THE KW1 & FR1 THE SAME FILTER? The KW1 is the cartridge. The FR1 is the housing. FV-FRKW1 is an item number used internally by Forest River. It is the KW1 cartridge.

3) WHAT IS THE MICRON LEVEL FOR THE KW1 FILTER? The KW1 is five microns. Micron rating has nothing to do with the quality of the filter, but rather the size of inclusions one wants to remove. Many filters accomplish their sediment removal (micron filtration) by wrapping cellulose (paper or cardboard) around an inner tube. If they use carbon, it is usually a few grams of granular carbon (carbon dust) impregnated or sprinkled on this cellulose. Our filters are solid certified green carbon compressed into a solid block. If you cut one in half, you will see the difference. Many other manufacturers use carbon from any available source, such as coal (anthracite) mines. Some advertise coconut carbon which is made from burning coconut trees. In our process, the coconut shells are used after the coconut meat has been removed. The trees remain alive and well to produce additional fruit. Where others use open pits to burn and make their carbon, our shells are burned in closed crucibles, where the heat and steam are captured to run a generator which provides electricity for the plant and significantly reduces harmful green house gas emissions. This process produces a carbon having more micro pores compared to other types of carbon and a unique binder system delivering a product with superior adsorption capacity and kinetcic dynamics. Because of contamination from "fracking" and the concern for chemicals in our water, we have chosen this more expensive carbon and manufacturing process to have a finished product with a high affinity for Volatile Organic Compounds (VOCs). The micron rating tells you what size particles the cartridge removes (the human eye with 20/20 vision cannot see smaller than 20 microns, but the type of carbon and the amount of carbon are the determinants for chemical/voc removal.

4) GALLONS PER MINUTE? The KW1 is rated at 2.5 gallons per minute. It’s at the top of its class for a five micron carbon block filter. Consider that each water fixture (lavatory faucet, kitchen sink faucet, toilet, showerhead, etc. is limited by code to 1 gpm. This filter will supply the shower at full force, the kitchen sink at full force, and still have sufficient capacity to wash your hands in the bathroom sink, all at the same time. Filters that flow at 4 gpm and 9 gpm do not exist without going to very large filters that would not fit in an RV. How can they even make this 9 gpm measurement? Again, they would have to have 9 bathrooms, kitchens, etc flowing at full capacity to consume 9 gpm. (A hose bib or water connection at a camp site could not supply that much and you would fill a 40 gallon holding tank in four minutes.

5) COMPARE A FILTER PURCHASED AT A “BIG BOX” STORE TO YOURS? Filters at Home Depot costing $7-12 would be the GE FXUSC. They are made of pleated paper. They remove no chemicals, tastes or odor. They MUST be replaced after 3 months because the paper begins to disintegrate. Those fibers will then flow to your hot water heater and stick and burn on the inside walls. Again, it offers no protection other than sediment removal.

6) IS THERE A REASON THE KW1 IS NOT LISTED ON YOUR WEBSITE? We supply the KW1 for the sole use of Forest River, because they wanted a product that was better than the standard. Therefore, Forest River was the most obvious distributor. However, the demand has grown so much for the cartridge that it will soon be on our website to help ease the shipping demand. Within the week, we expect to be shipping within 24-48 hours of the order being placed. The KW1 is made exclusively for us by an American company. We could not find a source for certified green carbon in the U.S. so the carbon is produced outside the U.S. but it is NOT from Taiwan or China. The KW1 has been awarded the Water Quality Association Gold Seal.

Personal statement by Dr. Ronald Martin: “Our filters were especially designed to meet the unique demands of an RV, including limited space, length of service, cost of operation and the varying types of water that we encounter as we travel in our RV. We are not a corporate giant making something cheap to put on the shelves of discount DIY stores that can be adapted to an RV. Forest River has been using our products since 1999. We are not the cheapest piece on the shelf, but we are the most cost effective, with most families using one cartridge for an entire 12 months. With that said, I know there are exceptions. Once near Shipshewana, I ruined a filter in 5 days. At first I was upset, but then I realized that that filth was not in my RV system and it wasn’t in my stomach. “

Dr. Ronald Martin of Original WaterPur Water Filters and WaterPur Replacement Water Filters at sales….sales at Water Pur…no special interest/conflict there.

Forest River water filter rep. contradicts his information, telling me that the KW1 that she is selling every day, for Forest River, is 30 microns. In addition, he is suggesting that GE is misrepresenting their GPM’s. He is definitely wrong regarding GE not make a carbon filter. You can see them for yourself at HD.

I don`t know exactly which unit I have, but I have tried a filter with the higher filter rating, lower number and I have very little flow out of anything in my trailer. I only use the "whole house" filter if I know I will be using my freshwater tank, which was the last 2 years when we hit the state parks a few times. this year I will be getting an in line filter for the hose.

If the KW1 is such a fine filter, why did they put that tit on the top and render the housing not usable for the standard 10” filters? This is simply to stop all of us from purchasing competitive filters locally. I agree the KW1 is a good filter but good filters of equal value can be found at half the price on line. I personally don’t care for not having the option of purchasing filters I want as replacements. I took my filter out and discarded it. I will use a Camco inline filter this season and bring water from home (RO system) for drinking and cooking.

Dr. Martin of Waterpur's reply above states that code limits faucets, etc to 1gpm. This can't be correct as my new Oxygenics shower head clearly states it is 2gpm on the front of the package. If the KW1 is rated at 2.5gpm I can only assume that is with a brand new filter. After a little bit of use it will certainly drop below 2.5gpm and be barely able to keep up with the flow of one shower head.

The guy sound like an infomercial on TV.

The trees remain alive and well to produce additional fruit. ???

I thought the carbon was from the coconuts not the trees; Really Seriously. I sure their competitors cut down the whole tree to make their activated carbon. UNBELIEVABLE.

Where others use open pits to burn and make their carbon, our shells are burned in closed crucibles, where the heat and steam are captured to run a generator which provides electricity for the plant and significantly reduces harmful green house gas emissions.???

Gross oversimplification and typical infomercial green BULL. That stuff is pure hogwash and neoscience.

THE REALITY is that activated carbon is a very poor filter material but a good absorber of VOC's. Paper pleated or other media filters are very good sediment filters but poor absorbers of VOC's.

The best RV filter's I've seen are made by Camco and combine a polypropylene outer layer for sediment and an Activated Carbon core. The are called EVO, I think. They used to make a ceramic filter called the CX90 that was even better than that but I don't think they are available anymore.

I am opting to change my FR1 for a two cartridge system. My original KW1 only lasted 6 weeks.

Quick stop at Costco and two cases of bottled water. I know, bad, bad, not green. Only used for coffee and cooking. And for the dogs.
Don't sterilize the tanks, nor worry about the filter.

In actuality, none of these systems do ANYTHING about the dissolved solids in the water. and most of them DO filter out the bacteria and cysts that may make you sick.

If you REALLY want the best best water, then you HAVE to use a RO system and only for your cooking and drinking water.

While they are LOTS of specs on all this. Most of it doesn't have any impact on the the quality of the water. Even the worst filters remove most of the harmful stuff and most systems we tie into have NO harmful stuff.

Lots of hysteria and unfounded fears feed this stuff, and I would not be suprized if some of it came from from or is amplified by the filter mfg.

THAT is the real science.
