AltoLab is a cheap and effective way of [[Altitude Training]]. It uses a chemical (soda lime) to remove the CO<SUB>2</SUB> from your exhaled breath, allowing you to rebreathe the air that now has lower O<SUB>2</SUB>. I have replaced my AltoLab with a [[DIY Altitude Training]] system that is cheaper and works better than the AltoLab system.
