Like other types of household appliances, water purifiers also need periodic maintenance to ensure smooth operation and best water filtration efficiency. In which, it is extremely important to replace the filter element on time, especially the 1,2,3 cores with a short lifespan of only 6-9 months.

Why do we need to change the water filter?
To ensure that  the water purifier is  always working efficiently, it is essential to have the water purifier serviced regularly. Replace the water filter element  periodically to ensure good operation of the machine, avoid unnecessary damage and ensure that the filtered water meets the standards.

Sediment core (PP core, folded paper core, wrapped cotton core ...), RO membrane removes different types of impurities in water, over time will accumulate dirt and can cause blockage when filtering water.

Carbon core (activated carbon), Cation core, mineral core, pH lifting core, Aragon core ... use filter materials, after a while, this material block decreases and loses its activity, so it is no longer effective as a filter. original and in need of replacement.

Need to change the water filter element periodically
Harm when not changing the water filter element on time
If you do not change the water filter periodically, you can face many harms:

The quality of filtered water decreases : Because the water from the input water supply when passing through the filter cores has "expired", the cores cannot retain impurities mixed in the water, do not add minerals, kill bacteria, deodorization, pH balance... Water purification efficiency is not achieved, the output water will not be clean, drinking is not beneficial to health.

Weak water output and reduced flow : Overdue water filter core accumulates many impurities, preventing the flow of water, making the water supply decrease, not enough for everyone to use.

 Reduced life of water purifiers : Expired water filter elements that have not been replaced in time will affect the useful life of unexpired filter elements, causing the remaining filter elements to decrease in life.

Pre-filter – 1,2,3 . core set
The prefilter included in the water purifier needs to be changed every 6-12 months. The pre-filter removes sediment and dirt from the water and prevents impurities from entering protecting the RO membrane or the rear cores.

RO Membrane
RO membrane can filter up to 99% of impurities from water sources. The RO membrane needs to be replaced every 2-3 years to ensure that the water purifier is working efficiently.

Functional filter element set

With core No. 1 you can see visually – when the core turns brown and lots of deposits on the outside. As for cores 2, 3, it is more difficult to see because of the closed structure.

But usually, the time to change the filter core No. 1 and No. 2 is about 3 months apart, so you can rely on core 1 to know the time to change core 2. And it's best to record the time for easy tracking. , core number 1 is 3 – 6 months, core 2 is 6 – 9 months, core 3 is 6 – 9 months. home pure water purifier price in bd

However, the life of the core depends on many factors such as the quality of the incoming water and the frequency of use by your family. If you use tap water from a clean water company, the filter life is equivalent to the above numbers. If the input water source is drilled well water, rain water, river water, lake water, etc., the replacement time should be shortened by 2-3 months compared to the manufacturer's instructions.
