Woods for infrared sauna are hemlock and red cedar from Canada and Alaska, with fumigation and phytosanitarycertificate. The wood are dried about 20days to get the best stability and durability . Semi-automatic machining system, based on USA equipment (Like MAX CUT 2000 Optimizing Cross Cut Saw),decreases the manpower effectiveness and makes high uniformity. Wood parts are treated with sawing, pressing, cold sanding, polishing and stability testing. Treated wood is tested with report from Laboratory in Texas, USA, to prove it comply with safety requirement for home using. All the electric parts are tested in high temperature room to make sure they function well within high temperature.
Control boxes are tested with vibration to make sure they work stably with speakers. Every product is examined with high temperature and humid surrounding to get the structure with enough stability. Every product is recorded during the whole producing process, and with only serial number for us to support products and after-sales service.

Quality system is approved by IS09001:2000. Products are certificated with CE, RoHS, ETL, and C-tick.
