After a long day, sometimes there is nothing better than a good shower, right? Afterwards, you turn on the bathroom fan to prevent moisture. An hour later, you’ve made something to eat, watched an episode of Glee, and called your friend to chat about it. You hear a faint humming, but can’t quite place it. A ha! That bathroom fan is still on, both exhausting air and increasing energy bills. Instead of beating yourself up about it, install exhaust fan timers to eliminate this problem while also reducing energy use.

Enough is enough, and too much is a waste

So, exactly how much is enough? Following a shower or bath, the fan should be left on no longer than 20 minutes. In this time, the fan is able to exhaust out moisture to prevent mold vacheron constantin 價錢 and the build-up of condensation. Keeping the fan on for less than this can result in the condensation problems that exasperate respiratory-related health issues such as asthma.

Understandably, it can be difficult to remember to turn the fan off, or remember how long it has been on. When it is left on longer than 20 minutes, it causes a waste of energy. Setting an exhaust fan timer allows you to maintain healthy air quality in the bathroom and reduce energy waste at the same time.

Choosing the right timer

Exhaust fan timers come in both mechanical and digital models. A mechanical timer operates the same way in which a classic oven-timer works, with the wind-up mechanism. These typically cost less than the digital timers, and can be set by the minute. Digital timers allow you to choose the operation settings with the push of a button. This type of timer does not allow for minute operation, but can only be set based on five or ten minute intervals.
