Other Filter Systems


Distillers heat water to speed up evaporation and then collect the water vapor as it condenses, killing disease-causing microbes, evaporating some toxins to gas and leaving other solids and chemical contaminants in the raw water reservoir. Distilled water may taste flat to some people because the water’s natural minerals and dissolved oxygen often have been removed.

Recommended for professional and or commercial industrial use.

Not recommend for everyday drinking water: distillers for drinking water or for household use remove the beneficial minerals from the water and require periodic cleaning.

Reverse Osmosis Units

There are two types of Reverse Osmosis is designed to make fresh water from sea, ocean, brackish or salt water. The lesser technology is made for fresh water only.

Reverse osmosis units force water through a specially made semi-permeable membrane under pressure, leaving most contaminants behind. Reverse osmosis units typically use more water than they treat, but are effective in eliminating all disease-causing organisms and most chemical contaminants.

True RO, or the salt water type of RO, are very effective units and often expensive. These units are great for offshore and commercial applications and are not widely available for household applications.

The Household or Fresh Water Type utilize a different type of fiber than the salt water type and operate with much less pressure. These filters do not remove all types of organisms and contaminants unless purchased with multiple cartridge assemblies rated for actual claims and similar to the filters offered above. These units are also more expensive than most other type filters rated for same capacity.

Recommended for offshore and some professional, commercial and industrial use.
