How to Choose the Best Whole House Water Filter for Your Needs

by Guest Writer

Installing a whole house water filter is an excellent way to improve your home’s water quality, but there are so many different models and options available that it can be difficult to know where to begin. What kind of filter should you get? Do you need one with ultraviolet light or bacteria reduction capabilities? How much maintenance will this new system require on a regular basis? These are all important questions to consider before making any final decisions about which type of water filter you want in your home. There are several different types of whole house water filters available on the market today: point-of-entry (POE), reverse osmosis, activated carbon, ion exchange, and hybrid systems. Each has its own set of upsides and downsides, and some are more effective than others in certain situations. Take a look at our comprehensive guide below for details on each type of WHF and which might be best for your needs.

Point-of-Entry Water Filters

Point-of-entry (POE) water filters are installed right at the source of your home’s water supply, which means they filter out contaminants as soon as they enter the water system. They’re a good option for those who don’t have the space or financial ability to install a whole house water filter. However, it’s important to note that since these water filters only filter the water as it enters your home, they’re not an adequate substitute for a full-house water purifier. POE water filters use granular activated carbon (GAC) to remove contaminants from water. This type of carbon filter is effective at removing chlorine, unpleasant smells and tastes from water, and certain contaminants like lead, mercury, and pesticides. Since it’s installed at the source of water, it can only filter contaminants that are found in the water we use for drinking, bathing, and other household uses.

Reverse Osmosis Water Filters

reverse osmosis water filter is a type of full-house filter that uses a semipermeable membrane to remove contaminants from water. The system uses a pump and pressure to force water through the membrane, where it is “cleaned” of many (but not all) impurities. When it comes to drinking water, reverse osmosis (or RO) is an effective solution for removing contaminants, particularly those that are larger than molecules, like lead and bacteria. RO water filters are also a good choice for those with extremely high levels of total dissolved solids (TDS) in their water. While most filters are designed for TDS levels up to about 500, RO systems can handle up to about 5,000.

Activated Carbon Water Filters

Like GAC filters, activated carbon water filters use granules of carbon to remove contaminants from water. The type of carbon used in these filters is different, though. AC water filters use a carbon with a higher level of “activation,” which means it has a higher capacity for adsorption. This makes it an excellent choice for removing certain chemicals and odors. AC water filters are most effective at removing organic compounds, including many contaminants that cause bad smells and tastes in water.

Ion Exchange Water Filters

An ion exchange water filter uses an ion-exchange resin to remove contaminants from water. These filters combine positive and negative ions with impurities in water, bonding to them and removing them from the water as it passes through the system. Ion exchange water filters are usually installed as a whole house water filter and are best when used to remove smaller, lighter contaminants from water. For example, these filters may not be as effective at reducing TDS as other systems, so they’re best for removing contaminants like heavy metals, pesticides, and volatile organic compounds (VOCs) that are smaller than molecules. Ion exchange systems are also useful for removing chlorine from water, which can help prevent an unpleasant taste and smell in your drinking water.

Hybrid Whole House Water Filters

Hybrid water filters are a combination of POE and RO technologies, so they filter water as it enters the home and remove larger, heavier contaminants like bacteria and VOCs using a specially designed membrane. They’re often used when water has extremely high levels of TDS or when there are certain impurities in the water that need to be removed. Hybrid water filters are not as effective at removing contaminants like chlorine from water, so they’re best for homes with very high TDS levels and contaminants like heavy metals, pesticides, and VOCs.

Final Words

Whole house water filters are a great way to improve the quality of water in your home. They’re especially useful for people with health issues caused by bad water quality or who are very sensitive to odors or tastes in their drinking water. When choosing a water filter, be sure to consider your needs and water quality. You’ll want to make sure the filter you choose is capable of removing the contaminants in your water. With the information provided in this article, you should be able to make an informed decision about which type of water filter is right for your home.
