How to Clean a Water Purifier Filter

Clean water is essential for our health as living creatures, and a water purifier plays a crucial role in making sure that the water we consume is safe and free from contaminants.

To prove this point, the most recent survey done on drinking water perceptions found that 59% of families feel their home’s drinking water is safe and clean, up from 57% the previous year too. However, the survey indicated that the number of families that consider their drinking water hazardous and not pure has increased from 15% in 2021 to 20% this year as well, which is interesting. But that’s not all.

Furthermore, there has been a significant growth in the number of households with a home water filtration system other than a refrigerator water filter since 2021 too. According to the same survey, almost half (45%) of households reported having a water filtration system and purifier at home in 2023, whereas only 40% had one in 2021! This shows the significance of learning about how to clean a water purifier filter in 2024.

However, to maintain the effectiveness of a water purifier, regular cleaning and maintenance of its filter are essential. In this comprehensive guide, we will walk you through the step-by-step process of cleaning a water purifier filter, ensuring that your purifier continues to deliver clean and pure water for you and your family.

Whether you’re using a countertop filter, an under-the-sink system, or a pitcher-style purifier, understanding how to properly clean the filter is key to its longevity and performance. We’ll go into discussing the importance of filter maintenance, common signs indicating when your filter needs cleaning, and provide detailed instructions on how to safely and effectively clean your water purifier filter at home.

Understanding Your Water Purifier Filter

Before going into the specifics and mechanics of how to clean your water purifier filter, it’s important to have a basic understanding of its function and importance.

Water purifier filters are designed to remove impurities, contaminants, and particles from the water, making sure that the water you drink is clean and safe. These filters come in various types, including activated carbon filters, reverse osmosis membranes, and UV filters, each with its own unique mechanism for purification.

Activated carbon filters, for example, work by adsorbing contaminants onto their surface, while reverse osmosis membranes use pressure to force water through a semi-permeable membrane, trapping impurities and allowing only clean water to pass through. UV filters use ultraviolet light to disinfect water by destroying bacteria, viruses, and other microorganisms.

Regular maintenance of your water purifier filter is essential to ensuring its continued effectiveness in removing impurities from the water. Over time, filters can become clogged with debris, reducing their efficiency and potentially compromising the quality of the water they produce.

Signs that Your Water Purifier Filter Needs Cleaning

Knowing when your water purifier filter requires cleaning is crucial for maintaining the quality of your drinking water and ensuring the continued efficiency of your purifier. Here are some common signs that indicate it may be time to clean your water purifier filter.

1. Decreased Water Flow

If you notice a significant reduction in water flow from your purifier, it could be due to a clogged filter. As contaminants accumulate on the filter, they can obstruct the flow of water, resulting in slower dispensing or filling times.

2. Unpleasant Taste or Odour

A dirty and clogged filter may produce water that tastes or smells unpleasant. The accumulation of impurities on the filter or the development of bacteria within the filter media could both be to blame for this. If you notice any changes in the taste or odour of your water, it’s a sign that your filter may need cleaning.

3. Cloudy or Discoloured Water

Clean water should be clear and free from visible impurities. If you notice that the water coming from your purifier appears cloudy or discoloured, it could indicate that the filter is no longer effectively removing contaminants. This is a clear indication that your filter requires cleaning or replacement.

4. Visible Debris in Water

In some cases, you may be able to see debris and particles floating in the water as it passes through the purifier. This is a strong indication that the filter is not functioning properly and may be in need of cleaning.

5. Increased Frequency of Filter Replacement

If you find yourself needing to replace your water purifier filter more frequently than usual, it could be a sign that the filter is becoming clogged or worn out faster than expected. Regular cleaning can help extend the lifespan of your filter and reduce the frequency of replacements.

Step-by-Step Guide on How to Clean a Water Purifier Filter

Before you begin, gather all the necessary materials, including a suitable cleaning solution (such as a mixture of water and vinegar), a soft brush or sponge, and clean, lint-free cloths. Ensure that you have access to the shut-off valve for your water supply and turn off the water to the purifier to prevent any leaks or spills during the cleaning process.

Next, find the filter housing on your water purifier. This is often a cylindrical or rectangular case that contains the filter cartridge. Depending on the design of your purifier, you may need to use a wrench or another tool to loosen and remove the housing from the purifier unit. Any other recommended tool in the user manual and guide is fine too.

Once the housing is removed, carefully extract the filter cartridge from the inside. Be mindful of any O-rings or gaskets that may be present and ensure they remain intact. Inspect the cartridge for any visible debris or buildup on the surface. If necessary, use a soft brush or sponge to gently scrub away any dirt or residue.

Fill a clean container with a mixture of water and vinegar or a recommended cleaning solution. Submerge the filter cartridge in the solution and allow it to soak for at least 30 minutes to loosen any stubborn deposits. After soaking, use a soft brush or sponge to gently scrub the surface of the filter cartridge, paying particular attention to areas with visible buildup.

While the filter cartridge is soaking, take the opportunity to clean the filter housing. Use a clean cloth dampened with the cleaning solution to wipe down the interior and exterior surfaces of the housing, removing any dirt or grime.

Once both the filter cartridge and housing are clean, carefully reinsert the cartridge into the housing, ensuring it is properly aligned and seated securely. Reattach the filter housing to the purifier unit, taking care to tighten any fasteners or connections as needed. Turn the water supply back on and allow the purifier to flush for a few minutes to remove any air or residual cleaning solution from the system.

After cleaning and reassembling the filter, test the water quality to ensure that the purifier is functioning properly. Pay attention to factors such as taste, odour, and clarity to verify that the water meets your expectations.

Tips for Maintaining a Clean Water Purifier Filter

Once you’ve cleaned your water purifier filter, it’s essential to establish a regular maintenance routine and plan to keep it in optimal condition. Here are some tips for maintaining a clean water purifier filter:

1. Set a Cleaning Schedule

Develop a regular cleaning schedule based on the manufacturer’s recommendations and your household’s water usage. Cleaning the filter at least every six months is typically recommended, but this may vary depending on factors such as water quality and usage patterns.

2. Inspect Regularly

Periodically inspect your water purifier filter for signs of dirt, debris, and wear. Pay attention to changes in water flow, taste, or odour, as these may indicate that the filter needs cleaning or replacement.

3. Use Filtered Water for Cleaning

When cleaning your water purifier filter and accessories, use filtered water instead of tap water to prevent introducing new pollutants too. This will help preserve the filter’s cleanliness and quality while also preventing contaminants from further building up.
