Houses today are being built tighter than ever to save energy. Even older homes often receive energy makeovers to replace drafty windows and doors and fill any cracks or gaps.

Sealing the envelope around the outside of your house is a great way to lower heating and cooling costs; but it can also trap stale, polluted air inside your home.

Fall is the perfect time of year to tackle home improvement projects that remove indoor air pollution from your home before cold, winter weather arrives.

Here are some great projects to consider to improve the ventilation in your home.

Upgrade Your Bath Vent Fans

One of the best ways to improve ventilation and remove excess moisture, which can cause mold and mildew, is by installing quality vent fans in every bathroom of your home.

Broan’s new InVent™ Series of fans have FoldAway mounting ears to make them easy to install in both new and existing homes.

InVent bath vent fans also feature a new, airtight damper mechanism and an easy to install duct connector.

They’re available with or without a light in models ranging from 50 to 110 CFM for bathrooms both small and large.

Bathroom vent fans with built-in humidity sensors, or installing wall-mounted humidity sensor switch, are great ways to turn the fan on automatically when the moisture level is high and off again when it returns to normal.

Install Central Vacuum System

A central vacuum system, such as the PurePower™ Series from NuTone, is a great way to clean your home while removing pollutants from the air at the same time.

Unlike canister or upright vacuums, a central vacuum system expels the dirty air outside your house, rather than recirculating it in your home.

Central vacuum systems are also much quieter than traditional vacuums, and the lightweight hose is easy to move from room to room.

Add Spot Ventilation

Installing a combination recessed light fixture and vent fan, such as the Broan 744 Series, is the perfect way to remove musty air from closets or humid air from laundry rooms.

The fixture mounts flush with your ceiling and looks just like any other recessed light fixture, while the 70 CFM fan draws air out of the room.

Improve Your Range Hood

Replacing your noisy, old range hood with a quiet, new model, such as the Allure III Series from NuTone, makes a good DIY project and can greatly improve the ventilation in your home.

Allure III hoods are 50% quieter than other range hoods in their class. They’re available in either white, black, or stainless steel finishes.
