How To Choose The Best Bathroom Fan With Humidity Sensor?
Which Model Can Help You Save Energy?
If you want to save money on your electricity bill, choose energy star-certified fans which result in great efficiency with less energy.
How Noisy Can You Withstand?
Although most bathroom fans with humidity sensors have an acceptable range of noise, many people have different requirements. For example, some people need a completely quiet environment to relax in the bathtub after a long working or studying day. Meanwhile, others don’t mind a low level of noise.
Once you have determined what you want, choose a model with a suitable level of noise. The noise level of a bathroom fan is measured in sones. The lower the sones are, the quieter your fan runs. Basically, a fan under 1.5-sone is quiet enough. But, if you want an extremely quiet environment, you can consider a fan under 1 sone.
How Large Is Your Bathroom?
If you choose a small fan for an enormous bathroom, it can’t provide you with a desired performance. Meanwhile, choosing a too powerful fan for a small room wastes your energy.
Do You Need An Adjustable Bathroom Fan?
Although an adjustable bathroom fan is more expensive than an unadjustable model, it is more convenient and useful. If the default setting of the humidity is too low, but you live in an area with a high level of humidity, you just need to adjust the setting (a knob or dial on the housing of your bathroom fan) with a flathead screwdriver. This feature can change from 50 to 80% relative humidity.
How Large Should The Housing Be?
Although you can add wood blocking to the ceiling joints for a too small housing, this requires more effort. Thus, make sure that the housing size fits your ceiling joists.
Which Brands Make The Best Bathroom Fan With Humidity Sensor?
Tech Drive
Tech Drive has 20 years in producing bathroom ventilation and exhaust fans at a reasonable price. Despite a cheap price, all of their products are made from good-quality materials and applied innovative ventilation technology.
