Filters, on the other hand, are more varied. Most have two or more layers, typically a pre-filter, an activated carbon filter and sometimes a particle or even a true HEPA filter. The pre-filter is made from a fine mesh that captures big stuff like pet hair and larger chunks of dust. Sometimes this part is separate from the more technical filters — which means you can remove and clean it without needing to swap out the whole thing. For all-in-one filters, you can vacuum the outside of it to remove larger particles.
