Benefits of Regularly Replacing your Water Filter

Water filters are an excellent/effective way to provide your household with healthy, great-tasting water. However, waiting too long to replace your water filter cartridge can cause your system to stop working, and it may even become a source of bacteria or mold.

Think of your filter cartridge like a sponge, collecting contaminants including bacteria, cysts, pesticides and more that are present in tap water. If not replaced on schedule, these contaminants can build up causing the system to stop working. Water may pass through the filter without removing any contaminants, or those contaminants may even leak into the water potentially causing health issues.

Prevent your water filtration system from breaking or being contaminated by doing the following:

  • Know what filtration system and model you use
  • Know when to change your filter cartridge
  • Know how to change your water filter cartridge

Learn how our Water For Life program can make filter replacements simple and cost-effective!

What Aquasana Filtration System Do I Use?

Not sure what filtration systems you're currently using? You can narrow down the choices by selecting a filter type. Aquasana has three types of filter systems which include: drinking water, whole house, and shower.

Drinking water filters include all under counter systems, plus the Countertop filter and the Clean Water Machine, so check your kitchen to see what solution you're using. Next, check your showers to see if shower filters have been installed at the head. Finally, go to the location where the main water line enters your home (most likely the garage or basement) and look for Aquasana-or Rhino-labeled blue tanks to see if you have a whole house water filter installed.

Once you determine which units need replacement filters, reference the model number on the data plate located on the whole house filter unit or on the drinking filter unit directly. For additional questions or assistance, please contact our customer support team.

When should I change my water filter cartridges?

The recommended replacement schedule for our filters varies by model and usage. Select your model and determine the replacement schedule by looking at the installation guide. Some models may require multiple components to be replaced, such as pre- and post-filter cartridges in whole house systems. Make sure to keep track of when each filter is replaced, or make the process super simple with our auto-shipped, discounted filter replacement program, Water For Life.
