Why proper bathroom ventilation is important?

Aug 2, 2020 | 0 comments

Ventilation could be considered the most important part in your bathroom. Exhaust fans guarantee the proper ventilation your bathroom needs to avoid bad smells, wet walls, odors, mold or even rust.

A bathroom exhaust fan is a mechanical ventilation device which, when ducted to the exterior of the house, draws out stale, impure and very humid air thereby improving the quality of indoor air.

To guarantee its function and its benefits, it is necessary to know some technical data, for example that the exhaust fan flow should be ten times more than the volume of air of the bathroom. Ventilation rates based upon eight air changes per hour are generally suggested. For most bathrooms, this works out to one CFM (cubic feet per meter) per square foot of bathroom area: a 7’ x 10’ bathroom would require a 70 CFM fan. A 50 CFM fan rating is recommended as a minimum for bathrooms 50 sq ft. So if you take a long relaxing bath, let water steam be absorbed by your exhaust fan to avoid wet walls and, consequently, either mold and mildew or even rust: humidity levels rise significantly creating the perfect breeding ground for mold, mildew and microorganisms that can negatively impact your health.

A bathroom exhaust fan provides you a healthy aired space. It can be installed on the ceiling as well as on the wall but never on the shower or above any type of source of heat (radiators, heatings, etc.) since that it is an electrical device. Noise level is also an issue to be taken into consideration when selecting bathroom ventilation. Bathroom fan sound levels are measured in sones: 4.0 sones is the sound of standard television operation; 3.0 sones is typical office noise; 1.0 sones is the sound of a refrigerator; and 0.5 sones is the sound of rustling leaves. For quiet bathroom ventilation the fan should be rated at 1.0 sones or even less.

As it is an electrical device, it can be turned on and off when needed by means of a switch. As simple as that! It is also important you choose the proper one: you should always look for the HVI-Certified label. This indicates the unit has gone through rigorous independent performance testing. Most manufacturers offer a wide range of products in different capacities to accommodate the air exchange requirements of the wide variety of bathrooms found in today’s homes. A knowledgeable HVAC contractor is recommended for installation: MADE ELECTRIC INC. can also help you choosing the right one for your need and install it properly.

In short, peace of mind, assurance that:

  • the product has been independently tested and certified to meet specific industry standards;
  • the product will perform as promised;
  • when an appropriately sized model is chosen and installed properly, proper ventilation will be achieved to maximize indoor air quality.

If you already have a bathroom exhaust fan installed, it is absolutely necessary you check it is clean and working properly: it may be consuming extra energy and not renewing your bathroom air. It needs a minimum but periodical servicing: check the powder accumulated on the ventilation screen and its internal piping.

PLEASE DO NOT install it directly to the attic because it is not a temperature controlled environment. We install it in the attic with insolated pipe and insolation on top of the fan for changes of temperature. Bathroom exhaust fans perform an important function by removing excess moisture from your home. It can cause to form mold and mildew on the underside of your rafters and decking as well as getting into insulation. The absolute best way to get that hot, moist air out of your house is to route it straight up through the roof and out a roof-cap on it. Even better, instead of using a flexible type pipe, you can use a smooth metal pipe to route it through the roof.
