What is a Whole House Water Filter?

A whole house filtration is a device installed at the point where the main supply pipe enters your house. It helps remove contaminants from your water before it reaches your faucets. You can install a whole house water filter yourself or hire someone else to do it for you.

Whole house water filters are great for homes with multiple bathrooms and/or laundry rooms. These systems are especially helpful for families with young children since they tend to drink more water. And they’re also beneficial for homes with older plumbing systems that may not be able to handle the extra pressure required to run a whole house water filter.

There are two types of whole house water filters: gravity fed and pressurized. Gravity-fed whole house water filters work by using gravity to pull contaminated water through a series of pipes and filters. Pressurized whole house water filters use pumps to force water through a series of filters and pipes. Both types of whole house water filter systems are available online and at local hardware stores.


Why Do I Need a Whole House Water Filter?

A whole house water filter is essential for any household. You need a whole house filter because your water has treatment/ disinfectant chemicals that can become aerosolized when heated in your shower or bath. These chemicals can cause respiratory problems and skin irritation.

Whole house filters remove chlorine, chloramine, trihalomethanes, and volatile organic compounds from your tap water. Chlorine is used to treat drinking water to kill bacteria and viruses. Trihalomethanes are carcinogenic chemicals that form during water heating. Volatile organic compounds are found in paint thinners and solvents.

Your whole house water filter removes these harmful chemicals before they reach your faucets. And since your whole house water filter is connected to every single faucet in your home, you never have to worry about running out of clean water again.



How Does a Whole House Water Filter Work?

A whole house filtration system filters out impurities from the tap. Whole house water filters remove unwanted particles from your water supply before they reach your tap or faucet.

They do this by using multiple filtration stages, including pre-filtering, main treatment, post-treatment, and sometimes secondary treatment.

Pre-filters remove large particles from the water supply before it enters the main treatment stage. These include kinetic degradation fluxion systems, sediment filters, carbon-based filters, and ultraviolet light filters.

Main treatment filters trap and remove smaller particles from the water supply. You can choose between sediment filters, carbon-based filters, UV light filters, and kinetic degradation fluxion systems.

Post-filters remove any residual sediments left behind by the main filtration system. You can choose between carbon-based filters, UV light filters, kinetic degradation fluxion systems, and sediment filters.

So if you’re wondering how a whole house water filter works, here’s a quick overview of its various stages.


How to Install a Whole House Water Filter System

There are several types of whole house water filters available today. Some are installed under sinks or countertops, while others are mounted on walls. Whichever method you choose, there are certain steps you need to follow to successfully install your whole house water filter system.

First, you need to determine where you plan to install the filter. Determine how much water line you will need to be removed to accommodate the entire system. Also, note whether you plan to install the system on the floor or on the wall.

Next, turn off the water supply and let the system drain completely. Open your home plumbing fixtures to allow any remaining water to flow out. This will reduce pressure inside the pipes.

Remove a section of the pipe using a hacksaw or drill. Sand the burrs left after cutting the pipe.

Begin installing the filter. Mount the system to the wall or floor. Ensure the wall behind the system can support its weight when it’s full of filtered water.

Check the water quality and pressure. Before using the tap for drinking water, check the water quality by flushing the faucets.


The Benefits of Installing a Whole House Water Filter System
