Enjoy Cleaner Water at Every Tap

Learn how the OAKS Whole House Water Filtration System gives you a better experience by providing cleaner, healthier water at every tap and removing contaminants from your water supply

Water issues cannot be seen with the naked eye, but they need a solution. 

 

Although Canadian Municipal water is treated before reaching your home, it still contains many contaminants that need to be removed before use in your home. Besides this, many Canadian homes use well water that is highly rich in iron, chlorine, sediment, sand, and bacteria. 

 

To remove all these contaminants, it is recommended to install the OAKS whole-house water filtration system to enjoy cleaner, healthier water from every tap.

 

What is a Whole House Water Filtration System?

A whole-house water filtration system is a point-of-entry filtration system installed at the main water line that treats water for every tap. 

 

It uses multiple filtration stages to remove various contaminants from water. 

 

Why Whole House Water Filtration Systems are Important

If you use municipal or groundwater in your home, you may face many problems, such as bad taste and odor in beverages and cooked food, as well as unpleasant experiences with cleaning, laundry, showering, and bathing. Due to unclean water, scale buildup can occur in your appliances, reducing their lifespan. 

 

It is very important to install an OAKS whole-house water filtration system at your home to enjoy clean, hotel-quality water. It will provide you with cleaner water that enhances the experience of cleaning, laundry, bathing, and appliance use.

How a Whole House Water Filtration System Works

A whole-house water filtration system uses multiple filtration stages to remove impurities such as sediment, chlorine, chemicals, and microorganisms from the water. It is recommended to use filtration stages according to your needs. The following are some stages used in whole-house water filters:

 

Sediment Filtration Stage

It is the first stage of a whole-house filter and is used to remove sand, dirt, rust, and debris that may have entered the water as it passed through the old, rusted pipelines of Canada. 

It has very small pores that trap such particles, protect the next stages from clogging, and enhance the system’s efficiency. 

 

Carbon Filtration for Chlorine and Chemicals

Activated carbon filters are commonly used to remove chemicals, including chlorine added to municipal water to kill bacteria, which can cause a bad smell and taste. 

Carbon filters are porous membranes that remove chemicals and chlorine efficiently, providing you with fresher-tasting, better-smelling water. Chlorine-free water is also proven to be gentler on skin and hair during bathing and to improve overall water quality.

 

UV Filtration for Microorganisms

Some whole-house filters include UV purification stages for additional protection, removing microorganisms such as bacteria and viruses. It disinfects the water without adding any chemicals. It is more beneficial for homes using well water, where microbial contamination is more common.

Additional Water Treatment Options with Whole House Water Filtration System 

Whole-house water filters may remove many contaminants, but they are not ideal for drinking and cooking, as they may not remove dissolved salts, heavy metals, and microplastics. 

If you are health-conscious, it is recommended to install an RO system along with a whole-house filter for cleaner, healthier, and hotel-quality drinking water. 

If the available water is hard, it is recommended to install the OAKS two-in-one whole-house water filtration and softener system. 

 

How to Choose the Right Whole House Water Filtration System

Before choosing the right whole-house water filtration system, you have to follow the following steps:

 

  • Test your water to determine the contaminant levels and types present in your available water. You may test it using the DIY method or contact an OAKS professional for testing and professional advice.
  • Estimate your daily water usage based on your family size to size your system.
  • Choose a system with filtration technologies and stages that remove all contaminants from the available water.
