Did you know air pollution happens within your home too? Air pollution is not just factory smoke or car exhaust. Pollen, dust mites, spores, pet dander, and mold also pollute the air indoors, causing allergies or even asthma. HEPA filters trap harmful particles, purifying the indoor air. However, like all other filters, even HEPA filters need to be changed regularly. If you have ever wondered "How often should I change my HEPA filter?" then this post is for you.

What is a HEPA Filter?
A HEPA filter, or High Efficiency Particulate Air filter, is a powerful filter capable of trapping nearly 99.97% of particles measuring 0.3 microns. The development of HEPA filters can be traced back to World War II. However, the HEPA certifications and standards were only established in 1983.
Modern HEPA filters are made of interlaced glass fibers. These fibers are turned and twisted in various directions to create a fibrous maze. When air passes through the filter, the contaminants suspended in the air get trapped in the maze.
How Often Should I Change My HEPA Filter?
The lifespan of your HEPA filter is determined by many factors, including:
- The number of hours you use it every day
- The speed at which you use the filter
- The air pollution levels outdoors
- The indoor air pollution levels
This means that the frequency at which a HEPA filter needs to be changed can vary between people and households. Some people may need to change the filter more frequently than others.
Even still, a general answer to your question "How often should I change my HEPA filter?" is every six months. You should change your standard HEPA filter at least twice a year. Some brands manufacture very strong HEPA filters that may last even a year. In such cases, you may need to change the filter just once a year.
It is crucial to watch out for signs that might indicate that it is time to change the HEPA filter. If you notice these signs, it is time for a change regardless of how many months you have been using your filter.
When Do You Know It Is Time to Change Your HEPA Filter?
If you notice these signs, you should immediately change your HEPA filter.
- Dirt around the air vents: Is there dust and dirt accumulating around your air vents? If there is, your HEPA filter may not be removing the contaminants from the air, and it is time to change your HEPA filter.
- Musty smell: Do you notice a musty smell in your house? It could be a sign that your HEPA filter is not working effectively, and it is time to change it.
- Allergies worsen: Are you or your family members suffering from allergies more than usual? It may be an indication that your filter has stopped working and needs a replacement.
- The filter looks dirty: If your filter looks dirty or damaged, then wait no longer. Replace your HEPA filter as soon as possible.
