Has your refrigerator water filter reached its expiration date?


Due to the remote location of your water filter on your refrigerator, many of you might often ignore changing it on a regular basis.


But you must be aware of the importance of routinely changing your water filter to your health. Once your water filter expires, it won’t filter water effectively as before, and becomes a breeding place for bacteria instead.


The longer you use your water filter, the more bacteria would remain in the device, further polluting water passing through it.

Manufacturers’ suggested replacement frequency - every six months - is just an average in the US; it can vary widely based on factors such as the quantity of contaminants in you water. In general, the more polluted your water is, the more frequent you should change your water filter.

When should you change your refrigerator water filter?

On average, you should change your water filter every six months or every 300 gallons of water.


The reason for that is once your water filter reaches its expiration date, it would be clogged by contaminants and even become a hotbed of bacteria.


At that time, you water filter will not only become less efficient at filtering water, but also affect water flow.


If you have a big family, you may need to change your water filter more frequently than normal since the device is very likely to have filtered 300 gallons of water in less than three months.

In addition, due to the facts that water is a daily necessity and children are more vulnerable to bacteria, we should act to keep the safety of water.


If your water tastes odd, that means you need to change your water filter because it might have stopped working.


What water filters are available on the market?

There are five main water filters available on the market: activated carbon filter, reverse osmosis filter, water ion filter, ultraviolet filter and infrared filter.


Among them, activated carbon filter and reverse osmosis filter are most commonly used.


Activated carbon serves to remove large particles such as rust and sludge from water. It achieves this by absorbing the contaminants and leaving them in the water filter.


Activated carbon filter’ popularity is all thanks to its efficiency at reducing chlorine in the water and removing unpleasant odors.

Reverse osmosis filter differs from other filters in that it uses a semi-permeable membrane to filter water.


Its approach is to filter water by forcing water through the semi-permeable membrane and leaving impurities in the filter.


The results of not replacing your water filter after it expires

Your water filter will be clogged if you fail to change it in time after expiration. Sediments in your water filter could prevent water from passing through the device and further slow the water flow.


Meanwhile, due to the wearing out of your water filter, contaminants accumulated in it could enter your water, giving it a strange taste or odor.


In most cases, your ice looks clear. But it would become overly cloudy if your water filter reaches its expiration date and is filled with various pollutants. Timely changing it can address the problem.

Normally, 8 ounces of water can pass through your water filter in 7 seconds. If the device is clogged or partially clogged, the water flow will slow down.


Any failure to routinely change your water filter will do harm to your health and safety. The water filter is used to remove pollutants, heavy metals and chemicals such as excessive chlorine and lead from water.


If you don’t replace it regularly, it will not protect you from these contaminants.
