After using the air filter for a period of time, it needs to be replaced. If it cannot be replaced in a timely manner and continues to be used, there will be serious consequences, which may cause the air filter unit to run under load and be scrapped. Although we cannot accurately predict the time to replace the air filter, we can make judgments based on factors such as the purpose of use and decide whether to replace the air filter.
We all know that medium efficiency filters are generally white filters, and we can judge by observing their color changes. If the color becomes darker or has already turned black, it is necessary to replace the primary efficiency filter; We can also observe the color of the bag body of the medium efficiency filter. If the color of the bag body shows black or mixed colors, it should also be changed.
The medium efficiency filter in the air filter needs to be replaced frequently, which requires users to observe regularly and replace it in a timely manner when there is a color change. For the replacement of high-efficiency filters, we cannot simply observe, we need to measure, not just observe for judgment.
