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.
A decade ago, Apple began switching from trackpads with mechanical clicking mechanisms to Magic Trackpads, where clicks are simulated via haptic feedback (in Apple’s parlance, the Taptic Engine). And, with Magic Trackpads, you can use Force Touch — a hard press — to perform special actions. By default, if “Force Touch and haptic feedback” is enabled on a Mac with a Magic Trackpad, a hard Force Touch press will perform a Look Up — e.g., do it on a word in Safari and you’ll get a popover with the Dictionary app’s definition for that word. It’s a shortcut to the “Look Up in Dictionary” command in the contextual menu, which is also available via the keyboard shortcut Control-Command-D to look up whatever text is currently selected, or that the mouse pointer is currently hovering over — standard features that work in all proper Mac apps.
