Nowadays, air purifiers are becoming a fashionable life-small home appliance, but whether the parents have always started up, so the filter is rarely replaced. In fact, once the internal filter material fails, it may not only fail to achieve the desired purification effect, but may be counterproductive. So when should the air purifier filter be replaced?
According to home appliance chain professionals, most air purifiers use HEPA as a filter material. However, if any purification material is used for a certain period of time, the purification material will tend to be saturated, resulting in a significant decrease in adsorption capacity. For a few air purifiers with intelligent reminder function, usually when the filter indicator light is on, the user should replace the adsorption or filter material in time.
Most air purifiers are not equipped with this function, so when the user feels that the purification effect is not obvious, the adsorbing or filtering material should be replaced. It is usually best to replace the filter material once a year. If you live on the side of the road, or if the indoor pollution is originally heavy, it should be replaced once every three months to six months. In this regard, after turning off the purifier and unplugging the power supply, the user can refer to the instructions for power-on inspection. If the filter material is found to be black, it means that it needs to be replaced in time. Ma Jun
