Exhaust Fans Description
A well-ventilated space is necessary for good physical and mental health as a stuffy space can make a person feel stifled, having an exhaust fan installed in the bathroom so air can pass from a window or door through the room out the bathroom is helpful for this purpose. Even just airing out the bathroom after a hot shower is important as the humid air doesn't let the bathroom dry and can cause mould to grow on the walls which is dangerous for the health. Probably to a greater degree than people understand from causing infections to being cancerous even which is why ventilation is crucial. Exhaust fans are not usually very high on consumption which is good as a lot of people run them for extended periods because fresh air is good at any time night or day.
Exhaust fans come in many sizes depending on the place that it needs to ventilate, with sizes anywhere from 6 inches to 24 inches even. Some have fins that are closed when not in operation and others are just a bare fan that is whirring away at full speed, larger ones usually are just bare fans and people install them in commercial kitchens and such spaces where there may be more smoke gathering up. These larger ones tend to make more noise as well while the smaller ones sound more like a continuous whirr.
Smaller bathroom exhaust fans also come with a drawstring to turn them on or of while that same string also shuts a small pop up like window behind them when not in use, this can be a good option as mosquitoes won't come streaming in when the fan is not on. The smaller exhaust fans are usually plastic ones and over time the parts do tend to take on a lot of wear and tear, but it could be a few years before it gets to that point!
