Two heating technologies sit inside the DR-998: an infrared quartz element that warms objects and people directly, and a PTC element that warms the air. The listing claims 60 percent more warmth than a standard 1500W heater, a number that should be read as marketing, but the idea behind it is sound, since radiant heat feels warmer at a given room temperature.
A humidifier, oscillation and a remote complete the package. That makes it the only unit here that attacks dry air, cold spots and operation from a chair at once. The cost is complexity: a heater with a water reservoir and a sweeping head has more parts that can wear or need cleaning.
Fill the tank with clean water and clean it often, since stagnant water breeds mould. Wipe the quartz tubes only when cold. Against the DR-968H below, it adds oscillation and a remote. It suits a large living room where you want warmth and moisture together. Because infrared heat is felt directly on skin and fabric, point the front toward where people sit, and keep curtains, throws and papers well clear of the quartz face. The mist output is best aimed away from the quartz tubes, so give the unit a spot where the water vapour can rise freely and does not drift across the glowing elements.
