It’s been over two years since my last rant.
I can now happily say this NFC tag hack works. No need to hack your purifier like with their previous kit (I almost purchased the kit — but eventually decided against it; was it worth the trouble?).
But these NFC tags are significantly easier to use. After ignoring the “your filter is at 0%” for the past ~6 months, it’s back at 100% with this. Remember to dust off and clean it once in a while (but even if you don’t, the air coming out is still cleaner).
So, entirely, worth it!
Speaking of which — Ikea has a whole new range of cool purifiers (including built-in a table). Quite cool (and sad that it’s come to this with all the pollution)!
