Noise level is impressively low at 37.5 dB, thanks to the brushless DC motor and aerodynamic design, making it suitable for quiet environments like bedrooms or offices. The build quality appears durable with a modern design, but being primarily made of plastic might not appeal to those seeking more robust materials. The inclusion of a 12-hour timer and multiple heating modes (High, Medium, Low, ECO, Fan Only) adds to its versatility, allowing users to balance heating needs and energy efficiency. The heater's silver color and sleek design should blend well with most home or office decor.

The Dr. Infrared Heater DR998 is a solid choice if you need a portable electric heater for a garage or large room. It offers 1500 watts of power and uses a dual heating system combining infrared quartz tubes and ceramic elements, which helps heat spaces efficiently and evenly. A handy oscillation feature spreads warmth throughout the room faster, avoiding hot or cold spots. You can also run it as a fan with the built-in humidifier, which adds moisture to dry winter air and can be useful even in warmer months. It has an electronic thermostat that allows you to set temperatures between 50 and 85 degrees Fahrenheit, helping maintain a comfortable environment without wasting energy.

Safety is well-addressed with tip-over and overheat protection, along with a cool-touch exterior that prevents burns, making it safer around kids or pets.

Noise levels are generally low thanks to the quiet infrared heating, though the fan function may be a bit noticeable. The heater’s build quality is solid, backed by a 3-year parts warranty and a lifetime filter, which reduces maintenance hassle.

On the downside, while it’s portable, it’s not the lightest heater out there, so frequent moving might be a bit cumbersome. Also, it’s designed for indoor use only, so it’s not suitable for unprotected outdoor areas. This heater is a versatile and reliable option for those looking to warm up a garage or medium to large indoor space with added humidity control and safety features.

Safety is well covered with built-in overheat protection and an automatic shut-off, giving peace of mind during use. Installation requires a professional electrician due to the 240V power and hardwired setup, but once installed, it offers flexible mounting options on the wall or ceiling to save floor space. The heater runs at a moderate noise level around 65 dB, which is relatively quiet for a fan-forced unit but might still be noticeable in very quiet environments.
