Many people use some kind of water filter to improve the quality of their water for drinking, cooking, food prep, and other tasks. But, if the filter has expired, it cannot clean the water to an acceptable standard. It can take some time to identify the problem if you’re not paying close attention to your water quality. In this article, we will show you four ways to identify an expired water filter.

1.  The Taste and Odor Have Changed

All water filters are designed to improve the taste and odor of the water to a certain degree. The improvement of the aesthetic qualities is a basic function, and if these characteristics have changed, it’s a sign that the filter may need replacement. This can be difficult to detect, the changes in the taste and odor may be subtle, and we tend to get used to things quickly. But, if the water doesn’t taste neutral or fresh, take a moment to consider when you last changed the filter.

2.  The Filtering Speed is Slow

One of the clearest indicators that the water filter requires replacement is a reduction in the flow rate. Every water filter has a commonality; the water flow is decreased as it passes through them. People tend to get used to a slightly slower flow rate quickly, and they may notice a slight reduction later. But, if the flow rate is much slower than normal, it’s a sure sign that the filter needs to be replaced.

3.  Black Mold Particulates

If you can see pieces of black mold in the water, this is a sure sign that something is wrong. This is a fungus that is linked to many health problems, and you shouldn’t drink water that contains it. The best solution to this problem is to clean the entire water filtration system with disinfectant and to replace the old filter with a fresh one. This is essential because there are likely to be mold spores living inside the filter. After you’ve replaced the filter, wash your hands, or you may contaminate the new filter when you place it in the system.

4.  A Metallic Taste

This is usually a sign that the water is hard due to a buildup of dissolved minerals, including calcium, magnesium, and iron. These materials form scale inside the filter, and the water may develop a metallic taste that’s unpalatable. Changing the filter will improve the taste for a short time, but the problem will return. The underlying cause is hard water, and the only way to fix that problem is to install a water softener.

The Filter Lifespan Explained

There are a few factors that lower the expected lifespan of a filter: the water quality, the volume of water used, the filter material, and the filter type. The expiration time for a filter should be printed on the rim, but this is not a substitute for your own experiences.
