How to Change a Water Filter Cartridge

Clean drinking water is the basis of healthy living, and the water filter cartridge is the key to ensuring the safety of your drinking water. Therefore, it is essential to replace the water filter cartridge regularly. This detailed guide will show you how to replace the water filter cartridge. I hope it helps.

Why do you need to replace the water filter cartridge?

The pollution of filter cartridges leads to a decrease in water quality

After a long time of use, the filter cartridge will accumulate various impurities, bacteria, and viruses, which directly affect the water quality after filtration, resulting in environmental pollution of drinking water, if you drink the filtered water directly, it will cause adverse effects on the body.

When the filter cartridge reaches the end of its service life, it can no longer filter effectively.

Different types of water filter cartridges have different service lives. If the filter cartridge is not replaced when its service life expires, it will seriously affect the water filtration effect in the later stage and will not be able to effectively remove impurities and pollutants in the water. Therefore, regular replacement of the water filter cartridge can ensure that the filter can effectively filter all pollutants in the water.

The actual effect of water purification treatment has weakened.

Aging of the filter cartridge may lead to blockage, and the blocked filter cartridge will reduce the water flow rate, and the actual effect will be weakened, resulting in a reduction in the cleanliness of the purified water. At the same time, the filter will continue to absorb a lot of organic compounds, if the aging filter is not replaced, it may seriously affect the water experience.

Replacement guide for different types of water filter cartridge.

The common water filter cartridges on the market are mainly divided into the following categories, and their replacement methods and frequencies are different:

Ceramic filter

It has a good filtering effect and can remove sediment, rust, and bacteria in water. Its replacement frequency needs to be determined according to different water quality, generally 6-12 months to replace once, or according to the filter surface dirt degree.

Replacement steps:

Remove the old filter cartridge: turn off the water source, unscrew the fixing nut of the filter cartridge, and remove the old filter cartridge.
Cleaning the ceramic filter: Rinse the ceramic filter with clean water to remove surface dirt, and try not to use brushes or hard objects to scrape.
Install the new filter cartridge: gently place the new filter cartridge into the filter cartridges and tighten the fixing nut.
Rinse the filter cartridge: Open the water source, rinse the filter cartridge, and discharge the residual dirt until the outflow water is clear.

Granular activated carbon filter

Generally, there are two types of filter cartridges, coconut shell activated carbon and compressed coconut shell activated carbon. Coconut shell-activated carbon filter can absorb the residual chlorine, odor, organic matter, and so on. It is usually replaced once every 3-6 months. The compressed coconut shell-activated carbon filter has a larger adsorption area and can remove pollutants in water more effectively. Generally, it is replaced once every 6-12 months, which is judged according to the color change of the filter cartridge.

Replacement steps:

Remove the old filter cartridge: turn off the water source, unscrew the fixing nut of the filter cartridge, and remove the old filter cartridge.
Install the new filter cartridge: gently place the new filter cartridge into the filter cartridges and tighten the fixing nut.
Rinse the filter cartridge: Open the water source, rinse the filter cartridge, and discharge the residual dirt until the outflow water is clear.

PP cotton filter

Melt-blown PP cotton filters can remove sediment, rust, and suspended matter in different water quality. At the same time, its replacement cycle is generally about 1-3 months, and it can be determined whether it needs to be replaced according to the color change of the filter cartridge.

Ultrafiltration membrane filter cartridge

Hollow fiber ultrafiltration membrane filter cartridge can quickly filter bacteria, viruses, microorganisms, and other harmful substances in different water quality. In general, the replacement frequency of the ultrafiltration membrane filter cartridge is 1-2 years, but it needs to be judged according to the specific situation of the filter performance decline.

RO reverse osmosis membrane filter

It can remove heavy metals, salts, organic matter, etc. in different water quality to ensure cleaner and safer drinking water, and the service life is generally replaced once every 2-3 years, which needs to be determined according to the pollution degree of different water quality, or according to the performance decline of the filter cartridge.

The filter cartridge replacement procedure of PP cotton, ultrafiltration membrane, and RO reverse osmosis membrane is the same as that of activated carbon. It can be replaced according to the relevant instructions of different brands.

How to determine whether the filter cartridge needs to be replaced?

Water yield

When the water filter output is very small, can not meet the normal needs. The filter cartridge is blocked, and the filter cartridge should be cleaned to restore the normal water volume, or when the water volume is still small after cleaning and can not meet the normal needs of people.

Taste

When the taste of the water filter decreases, and the taste is close to that of tap water, the chlorine taste of tap water cannot be removed, indicating that the activated carbon filter cartridge of the water filter has been absorbed and saturated. The activated carbon has failed, at this time, the filter cartridge should be replaced.

Filter cartridge appearance

When the appearance of the filter cartridge turns black or there is obvious dirt, it indicates that the filter cartridge has accumulated a large number of impurities and needs to be replaced. If not replaced, it will seriously affect the water quality after filtration, and long-term drinking will have an impact on health.

Service life

The life of the reverse osmosis filter cartridge of the water filter is generally about 2-3 years, and if the service life of the water filter cartridge exceeds two years, the filter cartridge should be replaced in most cases. Moreover, if the frequency of replacing the filter cartridge or the difference between them is a long time, the purification effect of the water filter will not meet our expected requirements, which is also harmful to the water purifier.

Filter cartridge replacement precautions

Select the right filter cartridge: Select the right filter cartridge according to the type of water filter and water quality to ensure that the filter cartridge can effectively filter the pollutants in the water.

Buy a regular brand: choose a brand with high credibility, ensure the quality of the filter cartridge, and avoid the use of inferior filter cartridges to affect the safety of water quality.

Pay attention to the replacement time: replace the filter cartridge regularly, do not wait until the filter cartridge fails to be replaced, to ensure the safety of drinking water.

Correctly install the filter cartridge: Install the filter cartridge strictly according to the instructions to avoid installation errors, resulting in water leakage or filter cartridge failure.

Regular cleaning of the filter cartridge: some filters can be cleaned, which can extend the service life, but pay attention to the cleaning method to avoid damaging the filter cartridge.

How to choose the right filter cartridge?

First, you need to choose the type of water filter. It is recommended to choose a well-known brand of water filter with after-sales service. For example, the ITEHIL reverse osmosis water filtration system has been tested and certified by FDA, CE, EMC, PSE, FCC, and RoSH, and the real filtration effect is 99%. It uses PP cotton + activated carbon + reverse osmosis membrane filter cartridge filtration, using the safest filtration steps.

Secondly, you can choose the right filter cartridge according to the water filter model and the water quality in different environments. The ITEHIL water purifier filter cartridges are RO and hybrid filters, and the hybrid filter is composed of PP cotton and activated carbon. The ITEHIL water purifier RO membrane has a nano-scale pore size (0.1 nanometers), which is smaller than other ordinary membranes (10-100 nanometers) and can truly filter out all harmful substances.

Under general outdoor water sources, the service life of the ITEHIL water purifier RO water filter is 600-800 gallons, and the hybrid filter is 300-400 gallons. However, if you use filtered tap water at home, your life will be longer.

Therefore, if you want to easily obtain safe and healthy drinking water outdoors or at home, you should choose an ITEHIL water purifier, and its filter cartridge cost is very low.
