What types of contaminants can a whole-house water filter remove? 

Your home’s water supply can contain a variety of impurities, including sediment, heavy metals, bacteria, viruses and chemicals like chlorine and hydrogen sulfide. While the source of your water is a crucial factor in determining its quality, a whole-house filter can remove some or all of these contaminants to make it safer for you and your family.

What’s the Difference Between a Whole House Filter and Countertop or Under Sink Systems? 

A whole house water filter is plumbed into the main water line and filters all of the water in your home. On the other hand, countertop or under-sink systems attach to a single fixture, such as the kitchen sink, and filter only the water you use there. This makes it difficult to keep a single faucet free from contaminants, so you’ll need a whole house system if you want to use clean, filtered water throughout your entire home. 

What Are the Most Common Types of Whole House Water Filters?

There are many different types of whole-house filtration systems to choose from, and each type of contaminant will require a different treatment method. These methods include carbon, ion exchange, ultraviolet (UV) light and sediment filtering. 

Activated carbon is the most common form of whole-house water filter, and it holds NSF certifications to reduce a broad range of organic contaminants. The highly porous media adsorbs pollutants and chemicals as the contaminated water passes through, trapping them and improving the quality of your water. 

Sediment filters help you maintain a clean, refreshing water supply and protect your pipes, fixtures, appliances and furniture from damage caused by rust or other sediments in your water. They can also extend the life of your appliances and save you money on costly repairs. 

Chemical filters work to eliminate a wide range of contaminants, including chlorine, chloramines and disinfection byproducts. They do this by changing the way that certain contaminants bind to the filtering media. 

Some active filtration systems use physical means, such as finely woven mesh. Others rely on chemical processes, such as ion exchange and reverse osmosis. 

How long do these types of filters last?

The lifespan of a whole house filter depends on the model you choose and the water it’s designed to remove. The APEC 3-Stage Water Filtration System, for example, can filter up to 100,000 gallons before you’ll need to change its cartridges. 

What Is the Cost of a Whole House Water Filtration System?

The cost of a whole-house filter varies dramatically, depending on the amount of water your home uses and what contaminants you’re concerned about. In addition, you’ll need to take into account the installation costs. 

How Can I Test My Water Before Buying a Whole House Filter?

If you’re concerned about the quality of your incoming water, it’s a good idea to have it tested by a state-certified laboratory. The results will tell you whether a whole-house filter is a right solution for you and your family.
