Venting Myths

When I was an appliance/lighting trainee, measuring a bath for ventilation was easy. Take the square feet of the bath and multiply it by 1.07 for the corresponding CFM equivalent. Supposedly this was an industry formula.

But, the formula doesn't work. First, bathrooms now have steams, specialty showers and multiple toilets. All of which creates more need for ventilation.

Also, the difference between a high and low CFM fan in price is minimal.

Have a look at a Panasonic bath fan.



There are plenty of decent fans, but Panasonic has the lowest sone or sound rating.

Green Tip: Buy a timer or moisture sensing switch, so the unit shuts off automatically.
