How, When, and Why Do You Need to Change Your Water Filter

Water filter removes chlorine taste, odor, zinc, copper, cadmium, and mercury from drinking water. Activated carbon filters, reverse osmosis, alkaline water ionizers, UV filters, and infrared filters are all options for soft water filtration. Pitcher water filters are popular and remove pollutants using granulated activated charcoal. Although they are inexpensive, the filter and cartridge must be replaced frequently.


The decision to replace your water filter is based on several factors. The estimated life cycle of water filters is usually measured in gallons of water. This is, however, just a recommendation based on typical water use. Since water use varies by household, this isn’t always a reliable measure. Several factors can influence the life of your filter. Take into account the following: ​

  • The overall state of your water in terms of pollutants and the amount of filtration needed.
  • If you have hard water (mineral-rich), which causes scale to form and clog the filter.
  • If you use far more water than the average family.
  • How well the water has been processed or filtered previously.

When an active carbon filter gets clogged (or can no longer attract particles and pollutants for whatever reason), it becomes inefficient and useless. When that happens, it’s time to replace it.


It’s probably time to change your water filter if you notice an odor in the water or if it takes on an unpleasant taste. There may also be a gradual drop in water pressure, signaling the need for a replacement. Of course. You could always depend on the visual indicator (found on clear-container filters) to tell you when the filter is dirty and needs to be replaced. Often double-check the manufacturer’s water use recommendations to ensure you haven’t gone overboard.


Your water filtration system will work properly if you replace your water filter as required. However, you should always have a backup filter on hand for fast filter swaps. Water filters are marketed by brand, and the component or model number can be found in the system’s manual or on the manufacturer’s website with ease.

You’ll need to regularly refresh your water filter if you want to keep removing pollutants. Otherwise, the flow rate of the water created by the water filter system would slow down, resulting in a malfunctioning (or non-functioning) system.


It would go a long way to ensure that your drinking water is both clean and delicious. Carafes, faucets, sinks, and countertops all have styles. A water filter can range from as little as $20 to as much as $2,000. Filters from well-known brands such as Amway, Aquasana, Brita, GE, and Whirlpool treat water using various technical methods.

Market reports’ buying guides will assist you in determining which water filter is right for you. Until investing in a long-term water filter, think about installation, convenience, and water filter tests. These studies look at water quality, contaminant levels, and EPA drinking water norm comparisons. Your local or state health department may be able to provide you with free test kits so you can learn more about the water in your area.
