Longtime Winix user here, but this is a fantastic write-up. I’m sure the NFC stuff will come in handy one day.

I've seen a lot of people getting Xiaomi air purifiers. Had no idea they put DRM on the filters, and they cost more. Really glad I went with Winix years ago, cheaper filters that last longer, and no DRM. I don't get why people can't just put a reminder in a calendar in the future to let them know to replace the filter instead of dealing with this stuff.
