In recent years, household water purification equipment has been partially popularized in our households and is an important measure essential to protect the safety of our drinking water. 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. In other words, not knowing the water purifier filter is really a waste of resources!

Let's first take a look at what effect the filter will have.

Reduced filtration and affects health

The first reaction of the filter element is blocked. 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 absorb 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 body.

Overworked 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 follow the raw water directly into the second-stage filter element, 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 it, which will shorten its service life very quickly. Originally, during this time, only the replacement cost of the "PP cotton filter" was only required. Because of the bad habit of not "replacement of the filter element regularly", 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 and increase the cost!

How do you know that the filter has expired?

Then how do we know that the filter should be replaced? The replacement is early, I feel wasted, and the replacement will affect the water quality. Everyone will not want to use a few thousand dollars of water purifier. Is the water still not safe? Buying a water purifier is not a comfort. It is to help us protect our family's health.

Generally speaking, the service life of the filter element: pp cotton filter: 3-12 months; pre-activated carbon filter: 3-12 months; ultrafiltration membrane filter: 3-12 months; RO membrane: 12-36 months; Rear activated carbon filter: 12-24 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.

Teach you several ways to judge 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 the demand cannot be met at this time;

2, the taste of the water is reduced, the taste 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 invalid;

3. The filter cartridge has not been replaced for one year.

The above situations have occurred, indicating that the filter cartridge needs to be replaced, but it is somewhat troublesome.
