A water filter can be a good investment, but for many homeowners this is a daunting prospect. The type of filtration system that you need can vary depending on the local water conditions, your water usage, your home layout and more. There are many brands and types of filtration systems on the market and it can be hard to make a final decision. Correct installation is important if you want access to clean and fresh water and it makes sense to involve your local water treatment specialist at an early stage. They can help you to find the right system to meet your needs and install it for you. Here are a few things to consider when it comes to choosing a new water filter system.

Point-of-Use vs. Whole-House

There are two broad categories of water filter systems, they are point-of-use (POU) and whole house, which is sometimes referred to a point-of-entry (POE). Although they both filter and clean the incoming water they are quite different.


This filtration system is installed at the point where the municipal water line enters your home. All the water is filtered to provide cleaner water to every tap and plumbing fixture in your home. This is an ideal option if you want cleaner water for showering, bathing, laundry and any other water related tasks. The downside is that this is a more expensive option because the system needs to be larger to handle the higher water volume.


A POU filtration system is usually installed at a single discrete point somewhere in your home. This is typically the tap at the kitchen sink to supply filtered water to that faucet only. This allows the homeowner to fill pitchers, make beverages, cook, bake and carry out food prep with cleaner water. Although you won’t get filtered water at every tap and fixture this is a less expensive option for people that want cleaner water on a budget.

The Filtration System Options

There are three main types of water filtration systems used in homes today, they are: activated carbon, reverse osmosis and ion-exchange water softeners.

Activated Carbon

Activated carbon is an enhanced version of charcoal that has been used to filter water for centuries. This media has a large surface compared to its relative size and the pores are very effective when it comes to trapping particulates.

Reverse Osmosis (RO)

The RO system forces the incoming water under pressure through a semi-permeable membrane. The membrane pores are very small, and only pure water molecules can pass through. This is a very effective method of filtration, but it takes time, so the filtered water is stored in a convenient tank for on-demand access.

Ion-Exchange Water Softening

This system uses resin media, the ions that cause water hardness are attracted to the surface and exchanged with sodium (salt) ions. This makes the water easier to use, and people sensitive to sodium can use a potassium water softener instead.
