BioSmart Technologies specializes in air purification and far infrared heating technology. It is based near Seattle, Washington where it provides full service and support from its own fulfillment center. BioSmart is a USA owned Washington Corporation with co-manufacturing facilities in Washington, Taiwan and China. All of our distribution and marketing is 100% USA owned and controlled. Over 70% of your purchase price stays in the USA and provides jobs to USA workers in our distribution network of over 1,000 dealers nation-wide. Beware of misleading claims: Some of our biggest competitors produce or buy their parts in China and then do a partial assembly in the USA and then claim their heaters are manufactured in USA. Be aware that under the current laws, even partial assembly in the USA enables one to be able to claim “made in the USA” even though the parts actually come from other countries (mostly China).
