Exploring Point of Entry Water Filter & Treatment Systems


Clean and safe water is a fundamental necessity for every household. Ensuring the quality of your water supply goes beyond just a refreshing drink. It impacts the health of your appliances, your skin, and even the taste of your food.

That’s where Point of Entry (POE) water filters and treatment systems come into play. In this article, we’ll dive into the world of point of entry system filters, exploring their types, advantages, disadvantages, and when you should consider using them.

What is a Point of Entry (POE) Water Filter?

A Point of Entry (POE) water filter is a comprehensive filtration and treatment system designed to purify the water at its entry point into your home.

Unlike Point of Use (POU) filters that are installed at specific faucets, a point of entry water system treats water as it enters your whole house house, ensuring that all the water you use and consume is filtered (filtered water) and treated for impurities.

Types of POE Water Treatment Systems

Whole House Water Filters

Imagine having a shield at the entrance of your home that filters out impurities from the water before they even step inside. That’s precisely what a whole house water filter does.

This type of Point of Entry (POE) system acts as the first line of defense, intercepting a wide array of contaminants and sediments present in your water supply.

These filters employ various mechanisms such as activated carbon, sediment filters, and sometimes even KDF media (a combination of copper and zinc) to tackle different types of pollutants.

The activated carbon is particularly effective at adsorbing chemicals like chlorine, volatile organic compounds (VOCs), and even certain heavy metals, which can contribute to off-putting odors, tastes, and potential health concerns.

Whole house water filters are especially beneficial if your water source is known to contain chlorine or if you’re concerned about the presence of common impurities.

They play a crucial role in ensuring that the water used for cooking, bathing, laundry, and other everyday activities is free from unwanted particles and chemicals, contributing to a healthier and more comfortable living environment.
