How Does a Whole House Water Filter Work?

A whole house water filter, as the name suggests, is a filtration system designed to purify the water supply for an entire household. This comprehensive system ensures that every water outlet, from showers to kitchen faucets, dispenses clean and safe water. Here’s how it operates:

Main Water Line Connection: The filter system is installed at the point where the main water line enters the home. This strategic placement allows the filtration process to occur before the water reaches any plumbing fixtures inside the house.

Sediment Pre-Filter: The first stage of filtration involves a sediment pre-filter which catches larger particles like dirt, rust, and sand. This initial step not only improves the water clarity but also protects the inner mechanisms of the filter system from getting clogged with debris.

Activated Carbon Filter: After the sediment layer, water passes through an activated carbon filter. This component is crucial for removing contaminants such as chlorine, pesticides, and volatile organic chemicals. Activated carbon works through a process of adsorption where these impurities are attracted to and held by the carbon particles.

Secondary Filters: Depending on the system, there may be additional filters like a copper-zinc and mineral stone filter which further reduce chlorine, and balance the pH of water, or even a sub-micron post-filter to catch any remaining microscopic contaminants.

System Maintenance: For optimal performance, filters need regular replacement. The frequency of maintenance depends on the water quality and the amount of water used.
