6 Disadvantages When You Don't Change Your Water Filter

Many families have invested in a water filter system for their homes. This can be of great help in cleaning up a household's water supply. The best purifiers can get rid of heavy metals, chemicals, chlorine, and more.

But one of the golden rules of using a purifier is to make sure you change the filters regularly. What happens if you don't change your filter? Well, a lot of serious disadvantages can emerge. A bad filter could interfere with your health and hygiene in more ways than you might imagine. Find out more about the risks of a poorly-maintained filter in the list below.

The Importance of Changing Your Water Filter

The purpose of any tap water filter is to trap certain materials and remove them from the water supply. Their entire functionality relies on them getting dirty and attracting contaminants. It's only natural, therefore, that they can get clogged up over time.

This is why filters have to be changed. Even the best sink water filter can deteriorate. If you leave a dirty filter in place, it won't be able to work as intended. This means that the purifier will be unable to deal with certain impurities, and your water may not be as pure as you hope. This can lead to the following unwanted effects.

1. Infection Risks

Your kitchen sink water filter helps to keep your family safe. It removes a wide range of impurities from the home water supply. These impurities and contaminants can include microbes, like bacteria and viruses. 

If left untreated, these germs can cause infections to spread throughout the family. Nobody wants to run the risk of getting ill from simply drinking their own home water.

A well-maintained purifier will reduce the risks of infection. But you have to change the filters for this to happen. Otherwise, the bacteria and viruses may be able to pass right through an old or dirty filter with ease.

2. General Health and Safety

Germs aren't the only threat that may be present in your household water. There are so many other toxins, pollutants, and chemicals to worry about. These impurities can pose many health risks to the whole family. 

Excess chlorine in the water, for example, may be linked to certain health issues. Heavy metals and VOCs are also dangerous when consumed over a long-term period. Even sediment and silt can make water more dangerous to drink.

If your filter is clogged and dirty, these threats and pollutants won't be stopped. So the water you drink may contain many unwanted elements. These elements could impact your general health and wellness.  

3. Bad Smell 

It's important to remember that purifiers also help to improve water's appeal. When treated with chlorine, water can take on an unpleasant smell. This can make it difficult for some people to drink.

A well-maintained purifier will be able to get rid of the source of the smell. This will help you enjoy great-smelling, clean water on a daily basis. But when filters get clogged, the smell can start to come back.                                                                              

In some cases, the smell might even get worse. If water is passing over dirty, grimy filters, it can pick up new odors. This might lead to your tap water becoming very unappealing.

4. Unpleasant Taste

The smell isn't the only thing to worry about with a dirty filter. You also need to think about the taste of the water you drink too. Usually, purifiers can help to improve the taste of water. They do this by removing chlorine and other elements which can interfere with the flavor.

But if you let your filters clog up, the taste can start to degrade. You might find that your water takes on a metallic taste, for example. This can be very unpleasant. It may even lead to some people drinking less water and suffering health issues in the process.

By changing the filter, you can help to bring back the clean, pure taste of your water. This can be a great benefit to the whole family. It will make your water not only healthier but much more pleasant to consume as well. 

6. Wasting Money

You might have spent a large amount of money on your kitchen sink filter. These kinds of investments have to be treated with care. Otherwise, you may find that you're throwing money down the drain, any time you use your water.

If you don't change your filters, the purifier won't be able to function correctly. In fact, it might not be having any effect at all. It could even be negatively impacting the quality, flavor, and smell of your water. 

If this happens, it will basically mean that your purifier is a waste of money, as it won't be doing its intended function. Those who want to get maximum value out of their purifiers, therefore, need to keep them in good working order.

7. Purifier Problems

Purifiers can struggle with a range of different problems. They have various parts and systems, and these parts can break down or fail. This can lead to the purifier owner having to handle repairs or payout for professional repairs.

Problems are more likely to happen if you don't change your filters. Dirt and grime will start building up inside the unit. This can cause a range of issues. Scale deposits might start to form due to excess minerals, for example. Other parts of the purifier system may be affected.

The issue can even spread to plumbing in your sink and other parts of the home. All of this can add up over time, in terms of repair bills. Getting the filters changed regularly will help the purifier system remain operational and reduce the risks of other issues around the home.


It's clear to see that changing your regularly is essential for getting the most out of your purifier. Without regular changes, filters will get clogged and dirty, reducing the usefulness of the system. 

So make sure you change your filters often, as instructed by the manufacturer. This will help you get the best out of any purifier, like the Crystal Quest WS Fluoride Under Sink Water Filter System.
