Importance of an HVAC Water Filter

Importance of an HVAC Water Filter

Everyone knows the importance of air filters in their HVAC system. They keep airborne contaminants from entering the unit and reducing the components’ efficiency. But water flows through your system too. Here’s why an HVAC water filter is also essential, for commercial and residential systems alike.

The Necessity of Water Filters

There are all sorts of contaminants that can come from your water and build up in your HVAC system. If you have hard water, it can cause scale: a layer of mineral deposits, such as calcium and magnesium, inside your system.

There can also be algae growth on and around the water, as well as just regular dirt. However, the calcium and magnesium cause a chemical reaction when the unit is warm, leading the other contaminants to bond with the surface and stick there. As this debris accumulates, it creates a barrier in your system that reduces heat transfer, forcing the system to use more and more energy.

A water filter eliminates these contaminants, improving energy efficiency. It also prevents corrosion and other problems that can necessitate more maintenance and ultimately shorten the lifespan of your system. Much like your air filter, a good water filter will improve efficiency, reduce overall maintenance, and help your system last longer.

Types of Water Filters

There are several different HVAC water filter types that can help keep your system clean. For a residential system, the best option is most likely a screen filter. Water passes through a screen similar to the way an air filter works. The screen captures debris, while letting clean water flow through.

For commercial or industrial systems, there are more efficient options. A centrifugal separator spins the water, so that debris sinks down to the bottom. And a microsand filter can filter out contaminants up to 50 times smaller than an ordinary screen filter. By choosing the right water filtration system for you, your system will stay healthy and efficient for years to come.
