To summarise, we propose six fast adsorbent characterisations that should critically be measured and reported for any new amine-functionalised DAC adsorbent to allow process designers to quickly screen the literature for the most promising adsorbents to study more closely. These are 1) the half-time of CO2 adsorption at 0.4 mbar of CO2 and 25°C, 2) a CO2 adsorption isotherm at 25°C with a focus on the Henry regime, 3) a H2O adsorption isotherm at 25°C, 4) density, 5) thermal conductivity, and 6) cyclic stability including the presence of O2
