Including filter system and high-performance Giardia filter.
Giardia is a tiny parasite that can enter water supplies as hardy cysts. You may also see it called Giardia intestinalis or Giardia lamblia, but the issue is the same: microscopic organisms that can travel with water and reach your household. Because these cysts don’t affect taste, smell, or clarity, you won’t spot them by eye. Many Fidelis homeowners choose an added layer of protection where water first enters the house to reduce that unseen risk.
Water can become exposed to contamination through events like pipe problems, cross-connections, or runoff that overwhelms treatment. Even when municipal or private treatment is in place, some families prefer an extra barrier for comfort—especially if someone in the home is sensitive to waterborne organisms. Installing protection at the point of entry ensures the same level of treatment for every shower, faucet, and appliance in your Fidelis home.
For a single, highly effective option to address Giardia across the whole house, choose a cyst-rated absolute membrane filter. These units use a physical membrane with very fine pores to strain out Giardia cysts rather than depending on chemicals alone. When sized correctly for your home’s flow, the system can protect multiple fixtures at once without gaps in coverage—making it a reliable mechanical solution for reducing the chance of cysts reaching your taps.
A whole-house membrane filter works best installed on the main water line so all incoming water to your Fidelis residence passes through the barrier. Performance hinges on choosing the correct micron rating and keeping the unit maintained so flow and protection remain steady. Some homes add a prefilter ahead of the membrane to remove larger sediment and extend membrane life, while the membrane stage itself is the key for removing Giardia intestinalis and Giardia lamblia.
