The filter cartridge is an essential component of a water purifier; it is cylindrical in shape, with both ends usually being equal, or one end may be shaped like an O-ring, while the other end may be round or pointed.
The material of the water filter cartridge varies depending on needs and purposes. Each filter cartridge has a specific function, and when combined, they form a comprehensive filtration system. The incoming water is sequentially circulated through multiple filtration stages to ensure the purified water is free from contaminants and bacteria.
Should I clean the water purifier’s filter cartridge?
Over time, the filter cartridge will accumulate dust and sediment, affecting water quality and potentially posing health risks. This is why many people choose to disassemble and clean the filter cartridge when they notice sediment build-up.
Should you clean the filter cartridge? While cleaning may restore some of its filtering capabilities, it does not guarantee the same level of water quality as a new cartridge. It is best to replace the cartridge as per the recommended schedule to ensure your purifier’s optimal performance.
Should you clean or replace the filter cartridge? The answer is that while cleaning may be an option, it is not advisable. It is best to adhere to the recommended replacement schedule to ensure your water purifier’s optimal performance. (Photo: Primer)
Improper cleaning of the filter cartridge can lead to several risks:
– Scrubbing the cartridge only cleans the exterior, failing to eliminate all contaminants, sediments, bacteria, and heavy metals.
– Improper cleaning can deform the cartridge, leading to bacterial contamination and reduced filtration efficiency.
Therefore, if you are not ready to replace the cartridge and intend to reuse it by cleaning, you should do so gently and carefully. However, it is essential to understand that filter cartridges have a limited lifespan, and you must follow the manufacturer’s guidelines on replacement intervals. Do not reuse old cartridges beyond their recommended lifespan, as they may be laden with accumulated contaminants.
How often should I replace the water filter cartridge?
Regularly replacing the water filter cartridge and conducting routine checks are necessary to ensure the purifier’s optimal performance and the quality of the purified water.
Today’s filtration systems often feature multiple cartridges with varying lifespans and functions, resulting in different replacement schedules.
Filter Cartridge #1
This is the primary filter that treats the incoming water, and it has a shorter replacement interval. It requires regular cleaning and replacement.
The first, second, and third coarse filters directly contact the incoming water, which contains various impurities and sediments. As a result, they are more prone to clogging and damage. Typically, you should replace the first filter cartridge after about 3-6 months of use.
If your source water is tap water, this cartridge will last around four months. However, if you use well water, the replacement interval shortens to just 2-3 months.
Filter Cartridge #2
This cartridge contains activated carbon, which eliminates odors, organic compounds, heavy metals, and chlorine from the incoming water. Therefore, it is generally recommended to replace this cartridge every 6-9 months.
When using tap water, you should replace this cartridge after eight months. However, if you are using well water, the replacement interval is reduced to 5-6 months.
Filter Cartridge #3
This filter is made of PP fibers with a 1-micrometer gap, effectively trapping sediments and other particles larger than or equal to this size. Any contaminants or sediments that pass through this membrane are trapped and retained.
The replacement interval for the third filter cartridge is 9-12 months. With tap water, this cartridge will last around ten months, while well water users can expect a lifespan of 7-8 months.
Filter Cartridge #4 – RO Membrane
The RO membrane is considered the most critical component of the water purifier, responsible for removing heavy metal contaminants and toxins that increase the risk of cancer, digestive disorders, and nerve inflammation.
The fourth filter cartridge has a longer lifespan than the previous ones. To ensure the purified water consistently meets the required standards, manufacturers recommend replacing the RO membrane every 24-36 months. For tap water, consider replacing it every two years, while well water users should replace it every 1-1.5 years. The cost of replacing the RO membrane is higher than that of the coarse filters.
