METALTRAP RV ULTRA™ is the ultimate in water filtration. This system was specifically designed to handle the toughest water sources, even those found in problem wells. Water is different everywhere you go, and the variety of contaminants you will find while you’re out on the road is unlimited. That’s why you need a filter designed for both city and well water sources. Don’t settle for less than the best. Most filters on the market today are ineffective at significantly reducing the tough contaminants like metals and Hydrogen Sulfide. That’s why you need the METALTRAP ULTRA™.


The METALTRAP RV ULTRA™ combines both of Hydropure Technologies’ exclusive, patented technologies (METALTRAP™ and PURESTART™) in a single cartridge. You can remove tough metals found in wells like iron, copper, and manganese that can cause staining and discoloration, while at the same time remove chlorine, pesticides, and fertilizers commonly found in city water sources.

CAUTION: Filter housing must be protected against freezing and extreme temperatures. Filter housings should not be in direct contact with sunlight for a prolonged period of time since UV rays can make housings brittle. Failure to the above may result in cracking of filter housing, water leakage, and water damage.

  1. hydropure (store manager)

    I recently purchased the METALTRAP Dual-Filter 14 System. During testing I discovered a leak in one of the filter housings. Contacted Hydropure and quickly received a response asking me to perform some simple tests in order to determine the correct replacement part that I would need. Completed tests and Hydropure shipped the replacement part at no cost to me.

    I was very impressed with the professionalism of the Hydropure technical staff and the rapid response I received. Definitely a 5 star company.

    Great company, great product, great customer service!
    We have had this for at least 5 years,. Purchased initially for rv travel in the silver valley Idaho mining areas due to metal contamination possibilities in drinking water. We have never tasted chlorine in our water, or any tastes…..unless a regular water hose is used…. does not remove that rubber taste.
    I did replace the plastic fittings with brass and with quick disconnect fittings. I purchased a Walmart pop up lid kitchen trash can and placed dual setup inside (with holes drilled in sides) to help the unit stand up….and to camouflage it.
    Be sure to drain after season and do not allow to freeze. I don’t replace filters but every other year, but also depending on use. Awesome product alone for safe, great tasting water in your rv!

    Instructions are a bit dated and confusing for setup. They should review someone who is unfamiliar with the product. Product is solid. Customer Service was extremely helpful when I called about using mounting brackets. I’ll be using a flow monitor on the front end to get the most from the filters. Satisfied customer.
