With the frequent outbreak of indoor air pollution, the popularity of air purifiers has greatly increased, and it has become an essential home appliance for family life. However, many people regard the air purifier as a "magic bullet" and think that it is only necessary to open it once, and it can be "medicated to the disease", completely ignoring the post-maintenance of the air purifier, etc. This is actually wrong.

The reason why the air purifier can improve the indoor air quality is because the pollutants in the air are intercepted on the filter screen. That is to say, the filter screen is very important in this purification process, and the air purifier can also Whether it plays a top priority. Although the filter can intercept pollutants in the air, it has a certain degree of saturation, so it will reach saturation when intercepting a certain amount of pollutants.

The so-called saturated state means that the interception of pollutants in the air is lost. It is justified that the quilt is filled with water and can no longer be loaded. When the filter is full, when the pollutants in the air pass through the filter, it is a "transition". It not only affects the output of the air purifier, but also reduces the interception effect of the filter on the air pollutants, so that the pollutants will still re-enter the air outlet from the air purifier, thus endangering our health.

In addition, a saturated filter screen will even cause secondary pollution. The filter will intercept the adsorbed viruses, bacteria and particulate matter, and will be blown back into the indoor air by the fan, causing secondary pollution and secondary pollution. The hazard is greater than the harm of the pollutants in the indoor air itself!

Not only that, if the air purifier does not change the filter for a long time, in addition to jeopardizing our health, it will also affect the service life of the air purifier. A blocked filter will increase the power output of the air purifier, thereby increasing The loss of the air purifier greatly reduces the service life of the fan. Therefore, be sure to replace the air purifier filter regularly.

So how do we judge whether the air purifier needs to replace the filter? We can consider the amount of air from the air purifier. After the air purifier has been used for a period of time, it naturally happens that the air volume is weakened. This means that the filter has reached a certain degree of saturation, and it is possible to start thinking about replacing the filter.

Of course, such judgment is purely based on the feeling, not very accurate, and the life of the filter has a great relationship with the use environment, that is, the greater the degree of pollution, the shorter the service life of the filter. Therefore, when purchasing an air purifier, we try to choose a product with a filter replacement reminder, with a smart filter replacement reminder, convenient and convenient!
