An exhaust can be useful in a bathroom or laundry, or any
room where there might be excess steam and moisture in the air. This will
prevent mould and mildew from building up in the room and potentially damaging
The first thing to figure out is how strong you need the exhaust fan to be in order to extract all the moisture in the air is to measure your room. You will need to measure the length, width and height of your room and then multiply those numbers together (L X W X H). Then you want to take this number and times it by 15, which is the average number of air changes needed per hour. For example an average sized bathroom which is 2m X 3m X 2.7m = 16.2m3 X 15 = 243. This simply means you want an exhaust fan with a minimum airflow of 243m3 per hour. Anything with a higher airflow will be even better in your room. This is just a very rough calculation, talk to your electrician or call us for more information.
