Including filter system and high-performance Giardia filter.
Giardia is a tiny parasite that can enter water supplies as resilient cysts; you may also see it called Giardia intestinalis or Giardia lamblia. Because the cysts are invisible, contaminated water won’t necessarily look, smell, or taste different, which is why many Lewis homeowners choose extra protection. Installing a barrier at the point where water enters your house prevents those microscopic organisms from traveling through your plumbing to showers, faucets and appliances.
Water can become exposed to contaminants through things like damaged pipes, cross-connections, or runoff that affects treatment systems. Even if municipal treatment is in place, some families in Lewis prefer an additional layer of defense—especially when household members are sensitive to water quality. A whole-house filter provides consistent protection at every fixture so you don’t have to worry about which tap you use.
For whole-house protection against Giardia, the most reliable single option is a cyst-rated absolute membrane filter. These systems remove Giardia cysts with a fine physical barrier rather than relying solely on chemicals. When sized correctly for your Lewis home’s flow rate, a membrane filter can serve every fixture without gaps in coverage, offering a straightforward mechanical method to reduce the chance of cysts reaching your taps.
A membrane filter dedicated to catching Giardia is most effective when installed on the main service line so all incoming water is treated. Performance depends on selecting the correct micron rating and performing regular maintenance to preserve flow and protection. Some Lewis homes add a sediment prefilter ahead of the membrane to extend its life, but the membrane stage is the critical barrier for Giardia intestinalis and Giardia lamblia.
