<p class="MsoNormal"><span style="COLOR: #1f497d; FONT-SIZE: 11pt">Keep in mind that ASHRAE’s “acceptable” level of CO2 has almost nothing to do with health. You could describe it as more of a “body odor” or “pleasantness” index. When the ambient levels of CO2 exceed their recommendation (~1000 ppm), people start to feel that the indoor air is less pleasant or “stuffy”.</span></p>
