[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Air filters, people. We have the technology.[/quote] Show me a filter that will remove CO2 and produce fresh Oxygen! All filter does is to remove farts as it also decrease Oxygen level. The window is all the technology you need. NO energy wasted! Zero cost! No added pollution from filter chemicals. No massive land impact from used filters. THERE is NO SUBSTITUTE FOR NATURE!!! [/quote] ...do you think classrooms are built with an airtight seal?[/quote] Do you know how much CO2 a human body produces in one hour..... multiplied by 30 kids and 6 hours? This requires SERIOUS fresh air exchange not tinny crack.[/quote]
