Low cost AQ monitoring

I am interested in low cost Air Quality monitoring options, and was interested to see Amsterdam uses the Smart Citizen platform and equipment (link below), however I am unable to get any response via their website and everything seems to have gone "off air". Does anybody know what is the status or alternative options.


Many thanks
