Household water purifier products are now more than just an ordinary commodity that is active in people's verbal conversations. It is not a money-making tool that has been speculated by water purifiers. It is really in us. In every household, it is an important measure to protect our drinking water safety! Therefore, in order to give ourselves more protection, we must have an in-depth understanding of the most important accessory of the water purifier product - the filter element. Seriously, not knowing the water purifier filter is really a waste of resources!
What is the impact of the filter cartridge expiration?
01, the filtering effect is weakened and affects health
One of the reactions of the filter element expiration is blockage. The blocked filter element will reduce the flow rate of the water, and the filtration effect will be weakened, which will reduce the “purity†of the purified water. Not only that, but also the filter element will adsorb a large amount of organic matter, which is easy to become a breeding ground for bacteria. The hotbed, the filter overdue will lead to drinking water pollution, at this time, if you drink it directly, it will absorb some harmful impurities into the body, causing harm to the human body.
02, overload work wastes money
The water purifier is basically filtered step by step. For example, the first-stage filter element--PP cotton is blocked, and the large particles of impurities such as sediment and rust in the water will directly enter the second-stage filter element along with the raw water, so that it is not responsible for filtering large particles. The second-stage filter element of impurities must take up this extra work, and overload work will shorten its life very quickly. Originally, during this time, only the replacement cost of the "PP cotton filter" was only required. Due to the bad habit of "changing the filter element from time to time", it is necessary to bear the double cost of the two filter elements, or even more. If the filter element is not changed for a long time, the operation of the water purifier will become dull, which will reduce the life of the water purifier. Increase the cost!
How do you know that the filter has expired?
Then how do we know that the filter element should be replaced? It is early to change, it feels waste, and the replacement will affect the water quality. Everyone will not want to use a water purifier of several thousand yuan. The water is still not safe water. Buying a water purifier is not a comfort. It is to truly help our physical and mental health and to care for the health of our family.
Generally speaking, the service life of the filter element: pp cotton filter: 3-6 months; pre-activated carbon filter: 3-6 months; ultrafiltration membrane filter: 3-6 months; RO membrane: 6-12 months; Rear activated carbon filter: 6-12 months.
But this is only a vague conceptual standard. Different water quality varies from place to place. The frequency of water purifiers is different. For example, during the validity period of the filter element, the whole family went to the door for a period of time. During this period of time, the filter element was not used. Is this time counted in the service life? It is difficult to judge.
Several ways to teach you when to replace the filter
1. The flow rate of the effluent becomes very small (indicating that the filter element is clogged, the filter element should be cleaned to restore normal flow), and the flow rate is still small after cleaning, and then the demand cannot be met.
2, the taste of the water drop is close to the tap water, that is, the chlorine smell of the tap water cannot be removed, indicating that the activated carbon filter element has been adsorbed and saturated, and the activated carbon is ineffective.
3. The filter cartridge has not been replaced for one year.
In the above cases, the filter cartridge needs to be replaced, but when this happens, your filter element may have expired.
