You should change your HEPA filters to maintain air quality, ensure your purifier runs efficiently, and protect the device’s motor from damage. Over time, HEPA filters become clogged with the particles they’ve trapped, which significantly reduces their effectiveness.
Why Clogged Filters are a Problem 😩
A HEPA (High-Efficiency Particulate Air) filter works by trapping particles like dust, pollen, pet dander, and mold spores in a dense mat of fibers. As the filter fills up with these pollutants, it becomes a barrier to airflow.
Decreased Air Quality: When the filter is clogged, air can’t pass through it as easily. This means your air purifier isn’t effectively capturing new pollutants, and you may notice a return of dust or an increase in allergy symptoms.
Reduced Efficiency: A clogged filter forces your air purifier’s motor to work harder to pull air through it. This can lead to increased energy consumption and higher utility bills.
Damage to the Device: The added strain on the motor can cause it to overheat and fail prematurely, shortening the life of your expensive air purifier.
When to Change Your HEPA Filter
The lifespan of a HEPA filter depends on several factors, including:
Usage: Filters in devices that run continuously or in areas with high pollution will need to be replaced more often.
Environment: Homes with pets, smokers, or those in areas with high pollen or pollution levels will fill filters faster.
Manufacturer Recommendations: Always check the manufacturer’s guidelines, as they often provide a recommended replacement schedule, typically every 6 to 12 months.
Some air purifiers have a built-in indicator light that signals when it’s time for a change. You can also visually inspect the filter; if it looks gray and dirty, it’s likely time for a replacement. Do not attempt to clean a standard HEPA filter, as this can damage the delicate fibers and ruin its effectiveness
