How to determine whether the high-efficiency filter needs to be replaced?
How to determine whether the high-efficiency filter needs to be replaced?High-efficiency filters are important for keeping indoor air clean and healthy. However, over time, high-efficiency filters gradually become dirty and ineffective. Only when the existing high-efficiency filter is scrapped can the corresponding high-efficiency filter replacement plan be completed. So how to determine that the high-efficiency filter has been scrapped?Among air filters, the cost of high-efficiency filters is much higher than other filters. Knowing how to determine whether a high-efficiency filter has been scrapped is crucial to replacing the filter in time to ensure good air quality. 1. First, pay attention to the appearance and color of the high-efficiency filter. Generally speaking, new air filters should be white or light gray. If you notice that the filter has become very dark or gray, that means the filter may have expired. The reason why the color of the filter surface darkens is that it has accumulated a large amount of dust and impurities and can no longer effectively filter the air. 2. During environmental testing, it was found that suspended particles in the room were significantly high. After ruling out other causes, we found that the diffuser plate of the high-efficiency air supply port had been removed, and the surface of the air supply port was also damaged and had black and gray marks. This means that the device cannot be used normally and we should replace it with a new filter in time. If the filter is not damaged, we can use the air outlet of the air volume cover to measure the air supply volume of each air supply port, and then increase or replace the air supply volume as needed. 3. If there is no abnormality in other air filters, but it is found that the air supply volume at the room outlet is less than half of the standard air supply volume, it means that the filter is blocked and we should replace the blocked high-efficiency filter. 4. Try touching the filter surface with your hand. If you feel noticeable dust, dirt, or impurities, the filter is too contaminated for further use. A high-efficiency filter should be smooth and free of any residue. If the surface of the filter feels rough or uneven when you touch it, the filter is most likely obsolete. 5. In addition, it is also very important to regularly check the age of the filter. Generally speaking, the service life of a high-efficiency filter ranges from 3 months to 1 year, depending on the type of filter and the environment in which it is used. If you forget the date of your filter replacement, check the filter's packaging or instructions for use to see how long it lasts. If used beyond the recommended lifespan, the filter is most likely expired. 6. Finally, if the air quality in the clean room drops significantly, or workers experience respiratory problems or allergic symptoms, it is necessary to replace the high-efficiency filter. High-efficiency filters work by capturing and filtering tiny particles in the air, such as dust, pollen, and bacteria. Once the filter fails, these particles cannot be effectively filtered out, which may lead to health problems. All in all, it's important to know how to determine if your HEPA filter has failed. By observing the appearance and color of the filter, touching the surface of the filter with your hands, checking the usage time, and noting any changes in air quality, we can tell if the filter needs to be replaced in time. Changing filters regularly will ensure we breathe clean, healthy air. |
