How to install the Purifier Card

As with most community additions to the Home Assistant Dashboard, the Purifier Card is available in the Home Assistant Community Store (HACS). Simply search for Purifier Card and it should pop up. If the card seems elusive, simply add the following repository to HACS and you will be able to find it: https://github.com/denysdovhan/purifier-card

Now, if for some unfathomable reason you don't have HACS installed (seriously, give it a whirl) or you're not in the mood to install it, you can still manually get the card into your system. The step-by-step guide for this is right on the GitHub page.

Setting up your Home Assistant Purifier Card

There's a smorgasbord of configuration options at your disposal, all listed in the documentation. Beyond the basic information, like which air purifier you're aiming to control, there are a few customisations you can fiddle with. For instance, I wasn't a fan of the animation and felt the card was a bit of a space hog, so I switched the compact_view to true.

Which air purifiers does Home Assistant support?

Since the Air Purifier custom card was released, it's been tested and proven to work with a variety of air purifiers. The developer initially wrote the code for their Xiaomi Mi Air Purifier, but it took a bit of time for feedback to come in about other models. So far, the Xiaomi Mi Air Purifier 3 and 2 series, the Coway Airmega 300S/400S (with the IoCare custom component), Dyson Pure Humidify+Cool, and Winix AM90 Wi-Fi Air Purifier have all been confirmed to be working with the card.
