Water filters are not meant to last forever, especially the water filters we use in our homes. However, instead of replacing it each time its efficiency decreases, you can also clean and reuse water filters.

Just keep in mind that there are only so many times you can clean and reuse your filter before its efficiency and filtration capacity decrease. After a certain period, you will have to replace it, irrespective of how much and how thoroughly you clean it.

How to Clean a Water Filter

Depending on the condition of your water, it is possible for bacteria, mold, and even fungi to grow inside your water filter. There are various ways to clean bacteria in water filters, but the most effective method is to soak it in a water and bleach solution. Mix one-part bleach with ten parts of water and soak the filter in this solution for at least an hour.

After it’s finished soaking, rinse the filter thoroughly with clean water to remove any lingering bleach. If you don’t want to use bleach, clean your water filter by soaking it in white vinegar for several hours and then rinsing it thoroughly with clean water.

When to Replace a Water Filter

To extend the life of your water filter, clean it regularly and replace it every six months to a year or as needed. If your filter is clogged and you cannot clean it, do not continue to use it. A clogged filter can cause contamination and worsen your water quality, so it is crucial to replace it as soon as possible.
