How to judge whether the air disinfector needs to replace the filter?
How to judge whether the air disinfector needs to replace the filter?To judge whether the air disinfector needs to replace the filter, you can look at the following aspects:1. Usage time Refer to the instruction manual of the air disinfector to understand the recommended replacement cycle of the filter. Generally speaking, the replacement cycle of HEPA filters is 3 to 6 months, and the replacement cycle of activated carbon filters is 1 to 3 months. If the usage time is close to or exceeds this cycle, you need to consider replacing the filter. 2. Filter status 1. Appearance inspection - Observe whether there is an obvious accumulation of dust and dirt on the surface of the filter. If the color of the filter becomes darker, or a large number of dust particles can be seen attached to it, it means that the filter has absorbed more pollutants and may need to be replaced. - Check whether the filter is damaged or deformed. If the filter is damaged, it will affect the air filtration effect and should be replaced in time. 2. Airflow changes - Feel whether the air volume of the air disinfector is significantly reduced. When the filter is severely clogged, it will hinder the circulation of air and cause the air volume to decrease. If you find that the air volume is significantly worse than before, it may be that the filter needs to be replaced. - Pay attention to the noise changes during the operation of the air disinfector. If the filter is clogged, the air disinfector may need more power to promote air circulation, resulting in increased noise. If the noise increases abnormally, it may also be a signal that there is a problem with the filter. III. Changes in air quality 1. Olfactory judgment - If you can still smell odors or feel that the air quality has not improved significantly during the operation of the air disinfector, it may be that the filtering effect of the filter has decreased and the pollutants in the air cannot be effectively removed. - Especially for activated carbon filters that require odor removal, if the odor persists, it means that the activated carbon may be saturated and the filter needs to be replaced. 2. Instrument detection - Use an air quality detector to detect air quality indicators around the air disinfector, such as PM2.5, formaldehyde, TVOC, etc. If the test results show that the air quality has not achieved the expected improvement, the filter may need to be replaced. - You can perform tests before and after replacing the filter and compare the changes in air quality to determine the filtering effect of the filter. IV. Equipment prompts 1. Indicator prompts - Some air disinfectors are equipped with filter replacement indicators. When the filter needs to be replaced, the indicator light will light up or flash to remind the user to replace the filter. If you see the filter replacement indicator on the device, you should replace the filter in time. - Note that the meaning of the indicator light of air disinfection machines of different brands and models may be different. You should read the instructions carefully before use to understand the specific functions of the indicator light. 2. Smart connection prompts - Some high-end air disinfection machines can be managed through smart connection methods such as mobile phone apps. When the filter needs to be replaced, the APP will push a notification to remind the user. If your air disinfection machine supports a smart connection, you can pay attention to the prompt information on the APP to replace the filter in time. |
