How Do Water Filtration Systems Work?

A whole home water filtration system is a device installed where the water main enters your home. Water filtration can seem complicated, but most whole home systems use a surprisingly straightforward process.

This process breaks down into three stages. The first stage pre-filters removes physical contaminants, the second removes chemicals, and the final stage remove any volatile organic compounds.

Let’s take a closer look at each of the three individual stages of the home water filtration process and see how they work.

Step One: the Sediment Pre-Filter

The sediment pre-filter catches particulates, like rust, sediment, and silt. Removing this material helps to extend the life of your home’s appliances, faucets, showerheads, and other fixtures. It also cleans up your tap water.

You should check and, if necessary, change out your pre-filters every few months. Changing the pre-filter helps increase the life of your system and keeps destructive sediment from getting into the workings of the unit.

 

Step Two: the Copper-Zinc and Mineral Stone Filter

After it processes water through the sediment pre-filter, your home filter sends it through the copper-zinc and mineral stone filter. Heavy metals can occasionally leach into drinking water and cause health problems.

The copper-zinc and mineral stone filter breaks down heavy metals and reduces the amount of scale in the water. It also helps prevent the development of algae and bacteria in water. This filter can even remove chemicals like chlorine. Chlorine is used as a powerful disinfectant, but it doesn’t have any positive effect after its initial introduction. Removing it won’t have any negative effects, but it will make your water healthier and help it taste better.

 

Step Three: the Activated Charcoal Filter

The activated charcoal filter uses a process called adsorption. No, we didn’t misspell “absorption”. Adsorptive filters attract contaminants like a magnet. They hold contaminants to the carbon-based filter, so they stay where they are instead of passing through your water.

This type of filter removes chemical substances like solvents that may bypass the first two filter stages. Unlike the first two steps, activated charcoal adsorption is a chemical process. It compliments the two previous filtration steps to further reduce impurities in drinking water.

 

 

Long story short: a whole home filtration system helps keep you, your family, and the water you drink safe and clean.
