Alpha Heater fixed this issue by copulating an antimicrobial filter with the device used to catch the dust to prevent mold from growing inside the device. No more foul odors like other heaters produce, which also include bacteria. The filter keeps the air free of dust and germs as it passes through the antimicrobial filter. How to Use Alpha Heater The Alpha Heater can heat rooms to 350 square feet and uses 650W (Low) – 1200W (High) amps and watts. Step #1 Plug-in the device and place the heater on a table, desk, floor or a nightstand or wherever you want to add warmth Step #2 Check that the safety button on the back of the device is activated because the heater will not blow hot air until the safety kill switch is activated.
