Canadian wildfires have become more and more serious, bringing a lot of impact to people’s lives. At this time, air purifiers have become one of the essential appliances in the home, it can filter out harmful substances and odors in the smoke, protect our health. But many consumers do not know how to judge whether the filter needs to be replaced when using air purifiers. This article will introduce you to several simple and effective methods.
Carefully observe the color of the filter
The color of the filter can tell us a lot about whether the air purifier needs to replace the filter. Usually, the darker or darker the color of the filter, the more pollutants it filters, and the shorter the remaining life of the filter. If you find that the filter has become very dark or dark, it means that its filtration efficiency has dropped significantly, in order to ensure purification effect, need to replace the new filter.
Test indoor PM2.5 concentration
PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns, it is one of the main particulate pollutants in the air, affecting human health seriously. When we use air purifiers, we can judge whether the filter needs to be replaced by testing indoor PM2.5 concentration. If the air purification runs at high speed for a period of time, indoor PM2.5 concentration is still high, then it means that the filter can no longer filter out PM2.5 and other fine particles, need to replace the new filter.
Check for odors on the filter
If you find that there is still an odor indoors, it means that activated carbon has been saturated with adsorption, and the filter can no longer filter out these odors, need to replace the new filter. At the same time, also pay attention to the odor components filtered by the filter, such as formaldehyde, benzene, xylene and other harmful substances. If the filter can no longer filter out these harmful substances, then it is necessary to replace the new filter in time to protect our health.
Replace cycle according to product manual
When buying air purifiers, manufacturers usually provide recommendations for filter replacement cycles. This cycle varies depending on different models and brands of air purifiers, but as consumers, we’d better replace filters according to product manual recommendations. This can ensure air purifier filtration effect and life span, while also ensuring our health.
In short, through these methods above, you can judge whether your purchased air purifier needs to replace filters. Regularly replacing filters is an important measure to ensure long-term effective operation and protect human health of air purifiers. If you have not purchased an air purifier yet, we recommend choosing a product with a filter replacement reminder function and replacing it according to product manual recommendations.
Jafända air purifier uses large-area HEPA filtration material with large filtration area and long life span, while using high-quality activated carbon with several times or even tens of times more weight than competing brands on the market, strong purification VOC and odor ability, is preferred for indoor air purification.
