No household can function properly without access to clean, healthy water. From cooking to bathing, laundry, washing dishes, and wetting your lawn, water plays a crucial role in a wide range of household activities. But this water is not always clean - different types and degrees of contaminants may be present, depending on the source. For instance, household water has been confirmed to contain chemicals, viruses, bacteria, sediment, heavy metals, and others.
Installing a whole house water filter ensures comprehensive protection for your family. It is a point-of-entry filtration system that connects directly with your main water source, which means every drop of water coming out of your faucet has been filtered. These filter systems can effectively reduce contaminants like sulfur, iron, chlorine, and others from your drinking water.
