Water Filtration System Basics

A water filtration system is designed to be installed in the plumbing system of your home, so toxins and contaminants are removed from your water before it flows from the faucets. It’s not uncommon to find a wide range of impurities in household water. These include substances like iron, tannins, arsenic, chlorine, excess magnesium and calcium, and others. With a filtration system in place, you can use your water without worrying about microscopic contaminants.

Common Types of Household Water Filtration

There are a few different types of water filtration systems for household use, each with its own properties. The most common among them are reverse osmosis filtration, carbon filters, and water softeners. Reverse osmosis is a process by which the water passes through a semi-permeable membrane to trap impurities. Layers of active carbon are used in carbon filters, and water softeners utilize tanks with salts that neutralize certain minerals.

Benefits of Filtering Your Water

Having a water filtration system in your home can provide a range of benefits. Not only will you enjoy healthy contaminant-free drinking water, but your appliances will work better, you’ll save money on bottled water, and you’ll have peace of mind knowing you are doing the right thing for your family.
