The first and the most important benefit of buying ALEKO® portable infrared sauna is its size. Unlike the non-portable type, these saunas can fit almost anywhere you want them to be installed. They can even fit your apartments or condo units without taking much space in your flat. ALEKO® Portable Sauna With Far Infrared, or FIR, heat is generated by using a specific wavelength of light that actually penetrates very deeply into the skin so the cells underneath can get the full benefit. This makes it superior to traditional steam or dry saunas that you are probably use to, but still gives the full benefit of making you sweat just the way you like it. Portable and light weight. Power input of 1000 Watt. The FIR portable sauna heats up to 113-140 F (45-60 C) within 5 minutes, and has a timer 5 to 60 minutes for enjoyment. Low power consumption. Features auto temperature control for safety. Sauna comes with a 5 feet (152.4 cm) 110 V AC power cord.
