Why Your Home Needs An Exhaust Fan

Today's homes are built to be "airtight" and energy efficient with few drafts. In terms of heating and cooling bills, an airtight home can dramatically lower your heating and air conditioning bills. In terms of air ventilation, however, an airtight home may be dangerous to your health and safety.

Why is an "Airtight" Home is Dangerous?
Having proper air ventilation goes further than just getting rid of foul odors. In fact, air exhausting is about:

Preventing excess moisture that cause biological pollutants like mold and mildew that:

Become harmful biological pollutants like airborne mold spores that can hazardous to your health and breathing
Compromise the structural integrity of the building like your walls, ceilings, and floors; and lower the value of your house by causing bathroom fixtures to rust, paint to blister, wall paper to peel, and grout to be moldy.

Eliminating harmful chemicals called Volatile Organic Compounds (VOCs) that naturally build up in your house from aging, decomposing, and curing building materials, carpets, furniture, and other household items.

So, good ventilation fans can keep the air in your home fresh and well circulated and thus help you take care of your family's and your home's well-being.

How to Select a Ventilation Fan
When selecting a fan, the purpose -- that is, central or intermittent ventilation -- should be your foremost decision-making criteria:

Continuous, central ventilation system are used to to continuously replace stale air with fresh, clean air in the whole house quietly and energy-efficiently. In the summer, in fact, circulating air can keep your house feeling 4 degrees cooler.
Intermittent ventilation fans are used in certain areas like the bathroom, kitchen, or garage to quickly exhaust moisture and chemicals. In fact, if you live in an "airtight" home, "bathroom" (intermittent) fans are quiet and energy efficient-enough to continuously ventilate your entire home.
