How often is it GOOD to replace water filter cartridges?

If you are using a household RO water purifier, you should know the importance of replacing the RO membrane and filter cartridges on time. This article helps you understand the importance of maintaining your RO water purifier to keep your drinking water pure and safe.

Benefits of replacing water filter cartridges on time

Replacing the filters on time can bring the following benefits:

• Ensuring that you always have clean, pure, and safe drinking water.
• Increasing the lifespan of your RO water purifier.
• Reducing maintenance and repair costs for your water purifier.

Factors affecting the replacement time for RO membrane or water filter cartridges include:

• The level of impurities in the input water.
• The TDS or hardness level of the input water.
• The amount of water you filter with your RO water purifier.
• The quality of the RO membrane or filter cartridges you are using.

If the water has a high level of impurities, high TDS, or if you use your RO water purifier to filter a large amount of water, then the filters and RO membrane will need to be replaced more frequently.

How often is it GOOD to replace water filter cartridges?

The schedule for replacing the RO membrane and filter cartridges we provide below is for an average household with about 4-6 members

When should the pre-filter be replaced?

If the pre-filter (filter 1, 2, 3) is not changed on time, dust and dirt will cause the RO membrane to clog, leading to reduced safety and hygiene, as well as decreased effectiveness and lifespan of the RO membrane.

By properly maintaining the coarse filter, RO membrane, and functional cores will operate more reliably. The ideal time to replace the coarse filter before the RO membrane is every 12 months at most. The replacement period may be shorter or longer depending on the quality and capacity of the filtered water. However, this is only an average, and for accurate replacement times, you may need to consult a technician or water treatment experts.

When should RO membranes be replaced?

RO membranes are the most important component of any water filtration system, including any integrated RO membrane water filter. If you replace the pre-filters at the necessary intervals, you may only need to change the RO membrane after 24 to a maximum of 36 months, depending on the type.

RO membranes may need to be replaced sooner or last longer depending on the TDS level of the input water, whether the source water is particularly hard, or if the water filter system does not have a membrane flushing feature. Replacing the RO membrane will depend on the amount of water filtered, the quality of the input water, and the effectiveness of the pre-filters.

The best way to know when to replace your RO membrane is to check the TDS level of the water. You will need a TDS measuring device to determine the TDS level of the water source you are using. You will know that your RO membrane is starting to deteriorate when the TDS level rises. If the input water is very hard or has a high TDS level, the RO membrane may need to be replaced more frequently. You must always check the specifications of your RO water filter system or, more specifically, your RO membrane. For example, if the RO membrane can clean up to 1500 ppm TDS, filtering water with a higher TDS level than 1500 ppm will reduce its lifespan.

When do you need to replace the functional cartridges?

In an RO water filtration system, the functional cartridges located after the RO membrane include: an Alkaline filter, a UV light, a nano-silver filter, a mineral filter, a far infrared filter, and a T33-GAC filter which helps to supplement minerals in the water, making it tastier and easier to drink. Typically, the lifespan of functional cartridges ranges from 12 to 24 months on average, depending on the quality of the water input, the daily amount of water used, and the type of filtration membrane.

In today's era, people are too busy, so it is becoming increasingly difficult to replace the filter element at the right time, which can affect the quality of our drinking water, thereby affecting our health. So is there a way to monitor the filter replacement and alert the replacement automatically? The answer is yes.
