What is an air filter?
An air filter is a device in your air purifier that helps remove particles in the air. The more efficient air filters will remove more than 99% of particles in the air. It means you can breathe cleaner and healthier air.
Different Types of Air Filter
Several different filters are available, depending on what type of filter air purifier you have. HEPA air filter is a popular option; these filters are typically made of micro-fiber and will easily remove particles in the air.
If your air purifier has activated carbon or charcoal as an air filter, it may need to be replaced more frequently than other types of filters.
Why do I need to change my air filter?
More efficient filters can trap particles in the air better. It means that they can remove more contaminants from the air. These filters will become less effective over time if not replaced regularly.
Once they are full of trapped particles, they won’t effectively clean the air. If you use this dirty filter, it will allow dangerous particles to make it back into your breathing space.
