Including filter system and high-performance Cadmium filter.
Cadmium is a metal that can enter household water when it dissolves from certain plumbing materials, nearby industrial sources, or contaminated soil and groundwater. Because you won’t be able to see, smell, or taste cadmium, the only reliable way to know if it’s present in your Lewis home is a proper water test. Many homeowners first consider cadmium treatment after a lab report shows elevated metals; when that happens it’s wise to plan treatment at the point where water comes into the house.
Although cadmium is commonly discussed in food and industrial contexts, it can also affect water quality and should not be overlooked. Boiling won’t remove dissolved cadmium, and it can be carried in both hot and cold lines throughout a home—so it may appear at kitchen faucets, in showers, and in water used for laundry. Treating water at the point of entry for Lewis homes reduces the chance of exposure by ensuring each tap receives filtered water.
For reducing cadmium on a whole-house basis, a point-of-entry reverse osmosis system is commonly the most effective single-filter choice. Reverse osmosis forces water through a semi-permeable membrane that can reject many dissolved metals, including cadmium, rather than only improving taste or odor. Installed where water enters a Lewis residence, this approach supplies filtered water to sinks, showers, and appliances and offers broad, consistent reduction compared with small under-sink units.
A whole-house reverse osmosis installation is typically combined with prefiltration to protect the membrane and post-treatment to make water comfortable for everyday use. Sediment prefilters prevent grit from clogging the system and carbon filters reduce chlorine that can shorten membrane life. Because RO systems produce a concentrated rinse stream, correct sizing and professional installation are important to meet a Lewis household’s demand.
