The laundry room can sometimes be a forgotten area of the home when it comes to Indoor Air Quality (IAQ). Most of the IAQ focus when it comes to ventilation is on the kitchen and bathrooms and rightfully so. However, the laundry room can be a large source of contaminants in your home. Let’s take a closer look at the laundry room.

If we are calling it a laundry room, then by name laundry is being done there which means there is a washer and in most cases a dryer. That means there are chemicals in the room. Off-gassing of cleaning detergents has a negative effect on your IAQ. Maintaining and cleaning these pipes with the assistance of the professional vent cleaners, it would help you to prevent having toxic air from the chemicals of doing laundry.

Unless you are also growing flowers in your laundry room, that smell is the off-gassing of the cleaning detergents. Then there are the machines themselves. With higher rate spin cycle washers and especially with dryers, their normal operation is going to produce heat and humidity. This can lead to an uncomfortable area to be temperature-wise and the extra humidity in the room can lead to mold and mildew growth.

Proper laundry room ventilation is often ignored in houses.

To keep costs down, the laundry room in a newly constructed home is frequently a bare space with a hole in the wall for a vent. Builders frequently leave the details of proper ventilation to the occupants. Still, it’s an important issue for two reasons:

  1. Washers emit a great deal of humidity, particularly when running on a spin cycle. Concentrated water vapor in the air condenses on walls and other surfaces and can trigger mold growth as well as consequences such as deteriorated structural materials.
  1. Dryers require specific venting for fire safety as well as air quality protection. Lint produced by driers is a proven fire hazard when not properly vented. Released into the household environment, airborne lint can present health issues if inhaled.

Things to Consider When Thinking of Optimum Ventilation

  • For best laundry room ventilation to remove excess humidity, a powered ceiling or wall exhaust fan is required. The CFM (cubic feet per minute) specification of the fan should accommodate the requirements of the specific room based on square footage. Consult manufacturer’s instructions to determine the proper CFM. If a ceiling fan is installed, it must connect to a dedicated duct that extends all the way to an external opening at the roof or a wall. Never vent into the attic.
  • Vent pipes connected to dryers exhaust heat, humidity, and highly flammable lint through a metal duct. Per the International Building Code (IBC), the dryer vent duct must be of smooth metal to prevent internal lint accumulation. It should be four inches in diameter and no longer than 35 feet. Sharp bends or turns in the pipe must be minimized. The vent must extend all the way through the wall and exhaust directly into the outdoor air. Due to fire hazards, flexible plastic dryer vent pipes common in the past are now prohibited by most local building codes.
