Including filter system and high-performance Giardia filter.
Giardia is a tiny parasite that can enter water when hardy cysts contaminate a supply. You may also see it called Giardia intestinalis or Giardia lamblia; regardless of the name, these organisms are small enough to travel with water and into your home. Because they are invisible, you won’t detect them by taste, smell, or sight, which is why many McDavid homeowners choose added protection at the point where water comes into the house.
Everyday risks like compromised pipes, cross-connections, or runoff can affect water quality and occasionally reduce treatment effectiveness. Even when your water is treated, some households in McDavid want an extra layer of defense—especially if family members are sensitive to water issues. A whole-house system delivers the same protection to every shower, faucet, and appliance, making it a practical choice for local homeowners who prefer more control over what flows through their plumbing.
For whole-house protection against Giardia, the single most effective option is a cyst-rated absolute membrane filter. This type of system uses a fine physical barrier to strain out Giardia cysts rather than depending on chemicals. When sized correctly for your McDavid home’s flow rate, it can protect multiple fixtures at once and reduce the chance of cysts reaching your taps. It’s a straightforward, mechanical solution homeowners trust.
Installed on the main water line, a whole-house membrane filter ensures all incoming water to your McDavid residence passes through the barrier. Performance hinges on choosing the proper micron rating and keeping the unit maintained so flow and protection remain consistent. Many installations include a prefilter upstream to capture larger sediment and extend membrane life, while the membrane stage targets Giardia intestinalis and Giardia lamblia. Mr. Pure Water can help size and match the system to your plumbing and household demand.
