Bathrooms were considered to be a space in a apartment where residents tend to give less importance while designing. However recently even bathrooms are being given a lot of notice while designing and building. Although still proper bathroom ventilation is missed out by many while designing. Bathrooms usually are lot more humid and the bathroom atmosphere tends to contain excess moisture. This disproportionate moisture can cause rotting of walls and ceiling and also trigger some structural damage. What’s more, humid environment support the growth of yeast, germs, moulds and many other microorganisms.
To defeat this problem, your bathing room has to be correctly ventilated. Some bathrooms have typical ceiling fans installed in them, but they don’t do the vital job of extracting moisture from the room. The finest fans that can be installed in bathing rooms are exhaust fans. They can eliminate foul smells, remove humidity and also help clear condensation off bathing room mirrors.
An effective and quiet bathroom fan contains few values that have to be made. If you already posses an exhaust fan but are not certain about its competence then you can proceed and do this plain test. Just hold a part of tissue paper near the bathroom fan. If the exhaust fan is competent, the handkerchief will be held tightly to the grill by the fan. Otherwise you can try out the exhaust test. Just lay a plastic handbag over the exhaust top and start the fan. The plastic bag ought to be filled with air in a few seconds.
Exhaust fans are rated by identifying the amount of air it is able to pull out per minute. They are calculated with cubic feet per min (CRM). Bathroom fans must be rated higher than 50 CRM to be an efficient and valuable one. Also in case your bathrooms are larger or have bathroom accessory fixtures like steam rooms, sauna or hot tubs, then you will have to invest in a larger exhaust fan.
