How Water Filtration Systems Work
Express Plumbing Service installs and services whole house water filtration systems for customers in and around Boise. They serve a wide range of purposes, from removing sediment to reducing water hardness, to eliminating odors. Here, we’ll explain how the process works and the different types of systems that are available. How Water Filtration Works Each type of water filtering device works different. But each uses the same general process to remove impurities and deliver a fresh, safe water supply: 1. Pre-Filtration The largest particulates are removed, including sediment and silt, which can cause serious damage to your pipes, other plumbing components, and appliances. Pre-filters take on the brunt of contaminants entering the system. They should be changed at least every two or three months. 2. Activated Carbon In the activated carbon stage, carbon molecules bind to chlorine and chloramines. These are removed from the water, so you and your family are protected against the effects of these compounds. 3. Post-Filter There is a post-filter that removes any remaining contaminants and sediment. This stage is located just before the water tap. Post-filters should be replaced every six to 12 months to ensure your filtered water is the highest quality possible. Types
