Metal Trap filter Over the years I have written numerous articles about water filtration, water quality and sanitizing your RV water system. There are lots of reasons to be concerned about the water we drink, especially when it comes to RV’s. When you travel in your RV and stop at different destinations on a regular basis you don’t know anything about the quality of the water you are using or drinking. It seems like every day you hear more and more about what is in the water we drink and how it can impact our health. I have always been an advocate for filtering the water in our RV and I am always on the lookout for the best possible method for filtering water.


Back in October we attended the RVDA convention/Expo in Las Vegas. Every year vendors bring their wares to the convention and introduce these new products to the RV industry. There are always one or two innovative products that catch my eye. This year it was the Metal Trap Ultra Dual filtration system by Hydropure Technologies.

 I had the opportunity to talk to Jerry Rademan, president and scientist/chemist behind the product. Jerry has a true passion for clean drinking water and water purification. He explained to me that the Metal Trap Ultra Dual System is the only filter system commercially available that will eliminate or significantly reduce all contaminants in one single system. He said, “The people at Hydro Pure Technologies are dedicated to our families and to our customers. We think there is no other food source that impacts the health aspect of our lives as clean drinking water! It is our goal to provide the best quality water that is available commercially”.

 Then Jerry challenged me. He said he would send me a Metal Trap Ultra filter system and let me be the judge. What he didn’t know at the time was that we recently moved into a new house where the drinking water has an odor and taste that makes you not want to drink it straight from the tap. And if anybody would know if the filter system works it would be my wife and my 13 year-old son, who constantly talk about the quality of the water in our home.

 Shortly after returning from the convention I received two Metal Trap Ultra Dual water filter systems. I decided to install the larger 14,000 gallon rated system on our drinking water in the house and use the 6,000 gallon rated system for the water system on our RV. The installation was simple, especially for the RV. The installation in our house required a quick trip to Lowes for some additional plumbing fittings to tie it into the existing water system.

 The thing I really like about the Metal Trap Ultra Dual System is that it works for both well water and city water, so it only makes sense that it would be great for RV applications. It filters out metals like iron, manganese, and copper and it also removes hydrogen sulfide which causes the rotten egg smell found in most well-water sources. It also filters out chlorine, chlorinated organic compounds that can be carcinogenic and it removes residual pharmaceuticals, pesticides and herbicides that can find their way into our city drinking water.  

 The metal trap Ultra dual system works on chemical oxidation, absorption and ion exchange principals that both remove and trap these metals and other unwanted contaminants. Most other filters work on physically straining the water, which doesn’t remove the contaminants that are dissolved in the water. When the water enters the Metal Trap filter the unwanted contaminants get oxidized and are trapped in the filter body. The activated carbon filters out the foul tasting and potentially harmful chemicals and contaminants. When the water enters the second filter it goes through a one micron sediment filter which filters out viruses, bacteria, fine silt, oxidized metals and un-dissolved calcium particles greater than one micron in size.

 The real test came after the system was installed, and it passed with flying colors. No more odors and the water is great tasting too. My wife said that it lived up to Jerry’s claim that water filtered through a Metal Trap Ultra filter system is better than any bottled water and better tasting too.

 Why don’t you be the judge!

  1. Hi – This is in response for information on the Tru-Pure Ozone system. The company was acquired by another entity and new branding/marketing will be introduced in the next couple of months. I am the marketing driector for the company and would be happy to provide you with service and warrenty information. We are also introducing a new product for the RV industry which allows you to ozonate your fresh water holding tank to purify the water/tank without ever using choloine – simply by flipping two switches anytime you want you will have pure water throughout the coach. You can reach me by email at [email protected]. Thank you.

    How long does the filter Last and how much is a new one?

    Does it filter flouride? I am trying to find a filter to remove flouride, a byproduct of making aluminum, sold as rat poison, and put in our water to prevent tooth decay with no studies shown that it does. I cannot find any water filters that mention removing this dangerous chemical from water, if anyone knows of one that does, please let me know. G Shea.

    I have a TruPure ozone water treatment system in my ’07 Dynasty. Unfortunately, it is no longer functioning and I cannot contact the company for repair information. I think they went belly up. Does anyone know for sure? Does anyone else have an ozone system?

    I really like the idea of an ozone system since ozonated water kills bacteria on contact and this is a great way to keep old sponges and countertops clean (I hate the smell of an old damp sponge.)

    Where do purchase bottle water at $1.66 a gallon? Apparently not at WalMart

    Does this one, or any unit anyone knows of, filter out flouride? I don’t like rat poision in my water! G Shea

    I had no trouble finding the information on the internet.

    I can’t find either the Duak Trap or the FeJo system on the internet for home/rv use.

    Please give website info, please.

    Sounds like a good application. We have only been fulltimers since June 09. I have installed a GE water cooler/heater purchased at Home Depot. It is secured in our motorhome and we have had no problems during travel. You can put from 2 to 5 gallon jugs in the cooler. Water jugs or refillable jugs are available at wal-mart, hd, lowes,etc. The nice thing is when plugged in or on generator we have hot water for tea, oatmeal,etc. Good clean water always available. Jugs can be removed during travel if needed.

    It filters out mangangese iron and copper. Darn, it’s in all my vitamins so i’m paying to get it back. Good deal. However not to make light of the subject, it sounds good and would probably be less expensive that the RO system that I have installed in my fiver. Yuma Az has such salty tasting water

    Would you mind posting a web site where information could be gathered concerning your water filtration system of choice? Did a Google search but couldn’t fin anything worthwhile.

    Please look into the Fejo Water Filtration unit developed by NASA engineers. As far as I’m concerned it’s the best around. We use it in the house and RV.

    I met Jerry at the Hearshy PA show and found what I was looking for. We are
    fulltimers and fill our tank whenever we can. This product makes us feel secure. Jerry is a real gentileman.
