What does Bacteriostatic mean in a water filtration context? Bacteriostatic filters do not kill bacteria, per say, but do inhibit the growth of bacteria within the filter*. In other words, the term Bacteriostatic means that the quantity of bacteria passing through the filtration system will remain static, i.e. bacteria will not multiply.
How do we achieve Bacteriostatic claims in Pentair Everpure filters? We use silver, a naturally occurring element that is highly effective for this purpose. Silver is known for its antimicrobial properties, is effective in fighting a wide range of microbes, and is preferred over other antimicrobials that are chlorine-, ammonia- or alcohol-based. Silver has been proven safe and non-toxic to people, animals and plants.
Pentair employs a proprietary technology to embed microscopic particles of silver in our bacteriostatic filter media. This filter media contains silver ions which attack microbes and inhibit their growth within the filter media of the water system, and also reduces off-tastes, odors and chlorine.
