What are Whole House Water Filters?

A whole-house water filter is a filtration system that is installed on the main water line of a home and provides filtered water to the entire home, including every faucet, shower, and appliance connected to the water line. These systems are “point-of-entry (POE)” filters because they remove contaminants from the water as it enters the home.

How Does Whole House Water Filters Systems Work?

The filtration process begins with pre-filtration, where larger particles and sediments are trapped before the water passes through a variety of filter media. These media include activated carbon and specialized resins (used to filter out specific contaminants such as chlorine, pesticides, and heavy metals).
Each filtration stage serves as a checkpoint, progressively purifying the water until it meets the highest quality and safety standards.
Finally, post-filtration adds a layer of purification to ensure that only the purest water reaches your tap. Understanding this filtration process allows homeowners to appreciate the comprehensive protection offered by a whole-house water purifier system. Unlike point-of-use filters, whole-house systems provide even filtration throughout the home and require minimal maintenance.

Do you Need a Whole-house Water Filter?

If your water source comes from a well, a river, or an area with known contamination issues, or if you want to address specific contaminants such as chlorine, heavy metals, or bacteria, then you need a specialized whole-house water purification system.
A whole-house filtration system ensures that every tap in your home delivers clean, filtered water, and if you use a lot of water in your home, or if your water is used for a variety of purposes in addition to drinking, such as gardening or pet care, then a whole-house filtration system will be convenient and efficient for you.
You should also consider factors such as the condition of your plumbing infrastructure and equipment. Whole-house filters not only improve water quality, they also reduce sediment and scale build-up, which extends the life of pipes and equipment. By carefully considering these aspects, you can determine if investing in a whole-house water filter is in line with your priorities.
