The lifespan of a HEPA (High Efficiency Particulate Air) filter depends on several factors, including the frequency of use, the level of air pollution, and the quality of the filter. In general, HEPA filters can last anywhere from six months to two years.
Most manufacturers provide guidelines for when to replace the filter, which is typically based on a certain amount of usage or a specific period of time. Some filters may also have a built-in indicator that signals when it’s time to replace the filter.
It’s important to follow the manufacturer’s guidelines for filter replacement to ensure that the filter is functioning properly and effectively removing particles from the air. A clogged or dirty HEPA filter can reduce the efficiency of the filter and may even cause the system to malfunction.
Regular maintenance, such as cleaning the pre-filter or changing it as recommended, can help prolong the life of the HEPA filter. Additionally, using an air purifier with a pre-filter can help extend the life of the HEPA filter by capturing larger particles before they reach the HEPA filter.
