Depending on the design of your house, it may not be all that easy to vent your dryer outside. Plus, you want to conserve as much heat as possible to save on your energy bill. So is venting inside dangerous?<\/p>\n\n\n\n
It’s not safe to vent gas or electric dryers inside. Gas dryers emit carbon monoxide, which is highly dangerous. Electric dryers don’t release carbon monoxide; however, dryer sheets and fabric softeners contain toxic chemicals that may cause respiratory problems. Venting inside also causes mold and condensation problems.<\/strong><\/p>\n\n\n\n In this article, you’ll learn:<\/p>\n\n\n\n Venting a dryer indoors means that you are releasing microscopic particles of lint. This is a combination of natural and artificial fabrics that are easy to breathe in. Many of these materials are known allergens and may even be toxic in some cases.<\/p>\n\n\n\n Airborne lint will continue to float throughout your home and on into other rooms. The lint can also build up in clumps near power outlets and heaters.<\/p>\n\n\n\n Other safety issues include:<\/p>\n\n\n\n The two main choices of clothes dryer are electric and gas, though gas is more cost-effective and quicker at drying large volumes of clothing.<\/p>\n\n\n\n While a gas dryer is more powerful, there are many health and safety issues to consider when installing and running either machine. An electric dryer can still be a danger, even though it does not combust a fuel.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n There are two main types of dryer vents: indoor and outdoor. The best and most common way of venting to the open air is through a duct pipe. Though it is possible to vent indoors with certain dryers with the right filters, some dryers are safe to use without any vents.<\/p>\n\n\n\n Building code M1502<\/u><\/a> of the IRC states that the dryer’s manufacturer’s recommendations should be followed. In some states, it is illegal to use exhaust pipes beyond a certain length. The code specifies that the duct should not exceed 35 feet (10m), so you may not even have the option of running the pipe to the outside.<\/p>\n\n\n\n The code also states that the dryer should not exhaust out to any part of your home, even the attic. Regardless of the code, the many health and safety issues with venting your dryer into your home should be enough to discourage you from trying it.<\/p>\n\n\n\n If the building codes allow for it, you may want to use the heat from the dryer to warm the rest of your home. Though venting indoors is not something you would do with a gas dryer.<\/p>\n\n\n\n For safe venting, there are several options for your dryer’s exhaust when you do not have a vent to the outside.<\/p>\n\n\n\n Ducting the exhaust out through a window is one of the simplest and cleanest methods. Though you do need to ensure that there are at least three feet (1m) of pipe extending outside to prevent blowback.<\/p>\n\n\n\n And when you stop using the dryer, you can bring the pipe back indoors and close the window. This is a solution without mess or the need to cut a hole in your wall. If it is cold, you may want to use a window kit<\/strong><\/u><\/a> to fill in the open section of the window while the dryer is venting.<\/p>\n\n\n\n Attic ducting is outside of the building regulations in most states. But, if you do send the exhaust to your attic<\/a>, use a lint trap<\/strong><\/u><\/a>. A reusable filter in the trap catches the lint. The filter is washable, and you should try to empty it monthly.<\/p>\n\n\n\n The trap prevents lint from blowing around in your attic, making everything you store up there dusty. Lint can also build up into flammable clumps around hot lightbulbs.<\/p>\n\n\n\n Exterior wall ducts are the best way of venting a dryer, as you can make the duct pipe short and keep the back pressure low. You can install a dryer wall duct<\/strong><\/u><\/a> that closes when there is no airflow. Wall ducts prevent cold winds blowing back in and rodents using the duct as a home.<\/p>\n\n\n\n Roof ducts are useful for gas dryers where you want to get all the exhaust fumes out of your home through the roof<\/a>. A roof duct will help disperse lint out and prevent backdrafts. Though, in some states with high levels of snowfall, roof ducts may become covered and blocked.<\/p>\n\n\n\n A less-known option is to install a ventless dryer, which is a good alternative for homes with smaller wash loads. The dryer circulates the humid air through an internal filter to trap the lint, which is easy to remove from the filter after each load.<\/p>\n\n\n\n\n
