Talented developer Denys Dovhan has given us a breath of fresh air - literally! They've recently launched an air purifier card (or simply known as Purifier Card) for the Home Assistant Dashboard. The thermostat card has been a household name in the Home Assistant community for a while, and the Purifier Card clearly draws inspiration from it. This nifty Purifier Card shows you the status of your air purifier and even allows you to control it via several presets.
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

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.
