If the Water Purifier Filter Element is Not Used Well, It is Equivalent to Wasting Life

In recent years, water purifiers have become a rigid demand for every household. Every household will choose to install a household water purifier when renovating a new house or customizing the whole house. As we all know, the core component of a water purifier is water purifier filter element. Then, does everyone really know the replacement cycle and maintenance methods of the filter element? In fact, many people are wandering in misunderstandings, not knowing that using the filter element incorrectly is a waste of resources and a waste of life!

Let's first take a look at what impact will be caused when the filter element expires?

Weakened filtration effect and affects health

The first reaction when the filter element expires is clogging. A clogged filter element will reduce the effluent flow rate and weaken the filtration effect, resulting in a decrease in the "purity" of the purified water. Moreover, the filter element will also adsorb a large amount of organic matter, which can easily become a breeding ground for bacteria. An expired filter element will lead to drinking water pollution. If you drink it directly at this time, you will absorb some harmful impurities into your body, causing harm to your health.

Overload work causes waste

Water purifiers basically work step by step filtration. For example, when the first-stage filter element - PP cotton is clogged, large particle impurities such as sediment and rust in the water will directly enter the second-stage filter element along with the raw water, making the second-stage filter element, which is not originally responsible for filtering large particle impurities, to bear this extra work. Overload work will shorten its service life very quickly. Originally, you only need to bear the replacement cost of the "PP cotton filter element" during this period. Just because of the bad habit of not "replacing the filter element regularly", you need to bear the double cost of two filter elements, or even more. If the filter element is not replaced for a long time, the operation of the water purifier will also become slow, which will reduce the service life of the water purifier and further increase the cost!

How to judge that the filter element is expired?

Then how do we know when the filter element needs to be replaced? Replacing it early feels like a waste, and replacing it late will affect the water quality. No one wants to spend thousands of yuan on a water purifier but still drink unsafe water, right? Buying a water purifier is not for psychological comfort. It is supposed to genuinely help us protect the health of our families.


Generally speaking, the service life of filter elements is as follows: PP cotton filter: 3-12 months; Pre-activated carbon filter: 3-12 months; Ultrafiltration membrane filter: 3-12 months; RO membrane: 12-36 months; Post-activated carbon filter: 12-24 months.

But this is only a vague conceptual standard. Water quality varies from place to place, and the use frequency of water purifiers is also different. For example, during the validity period of the filter element, the whole family went out for a trip for a period of time, and the filter element was not used during this period. Should this period be counted in the service life? These are all difficult to judge.

Teach you several methods to judge when to replace the filter element

1. The effluent flow rate becomes very small (which indicates that the filter element is clogged, you should clean the filter element to restore the normal flow). After cleaning, the flow rate is still very small and cannot meet the demand;

2. The taste of the effluent decreases, and the taste is close to that of tap water, that is, it cannot remove the chlorine taste of tap water, indicating that the activated carbon filter element has been adsorbed to saturation and the activated carbon is invalid;

3. The filter element has been used for one year without replacement.

If any of the above situations occur, it means that the filter element needs to be replaced, but it is a little bit of trouble to judge.

To help consumers solve this troublesome problem, most of Langmu water purifier products are equipped with a filter element life expiration reminder function. In addition, we can confirm the service life of the water purifier filter element through our own use experience, so that we can easily grasp the replacement time of the filter element until we reach the upper limit of the filter element life range, which saves money and worry!
