Product Description

This powerful and compact unit can treat up to 300 Gallons of water per .5 cu/ft of our DI Resin. Now you can get DI Water for a Spot Free Rinse anytime and anyplace using our portable DI setup. Utilizing our top of the line Lead Free 3/4" Brass Hose Fittings, easily connect to any hose bib in the United States. We have also included 4 feet of our award winning custom hose.

RV Water Filter Store

We manufacturer top of the line RV Water Filtration Systems, and we have been serving the industry for nearly 30 years.


Cheap In-line filters are commonly rated at 100 microns - or not at all. Our Essential Series goes down to 0.5 Microns. The Virus Hero(TM) filter elements have an “absolute” rating at 0.2 microns, removing or reducing contaminants, viruses, and pathogens other filters can't.


In-line filters often restrict flow. Most RV Parks & Campgrounds offer only 40 PSI at the hose. Our RV water filter system uses extra-large filter canisters, giving you much better flow, even under heavy demand.



I got exactly what I ordered, safely packaged, in a timely manner at a good price. Expert help is available when needed. What more could I want.

I appreciate your prompt service. So far the filter is working good. It's the first time I've ordered from you after many years with another company.

I enjoy the fact that I can call and make an appointment and they call back at the time I selected and get to talk to a person with questions. I then order and have what I need in just a few days.

Very knowledgeable and helpful in the selection, use and maintenance of their products. My water initially tested very hard, after installation the water definitely felt different and tested all green (softest). Bar soap in the shower didn't lather well in the past, now I have bubbles abound! Thanks a great product and information!
