A dryer vent hose helps to vent the hot and humid air from the clothes dryer to outside of the home or business. Dryers create a lot of heat and if it is not properly vented they can become a fire hazard. Most home dryers are tumble dryers that use either a timer or a moisture sensor. These flexible hoses should be made of metal not plastic or vinyl.

Regular cleaning of your metal dryer vent hose will keep your dryer efficient and cut down on any possibility of a dryer fire. Vent brushes are a brush on a long flexible handle which can be inserted into the dryer venting system to clean out any lint that has escaped the lint trap. If the clothes seem to be taking a long time to dry it could be caused by a hose that has too much lint built up in it.

Replacing and installing a hose is a simple process. Simply clamp the hose to the dryer to the outgoing vent system. You want to use the shortest possible hose. Dryer vent hoses that are too long can trap lint which can catch fire. The length of the hose should be short enough that it stretches without any stress on the hose but short enough that there are not too many curves and kinks which can cause lint to become trapped. Always watch for crushed areas of the hose which can cause the appliance to function with less efficiency.

Never repair a hose with duct tape. There are some things that duct tape is simply not a good use for. If you must do a repair use a metal tape. Metal tape is long lasting and fire resistant.

Most dryers and hoses have a standard size. If you somehow ended up with an odd sized dryer outtake vent there are adaptors that can be purchase so that it will fit to a standard vent. It is not normally a good idea to increase the diameter of the exhaust system. The dryer is made to work with a certain amount of out flowing air. Messing with the air flow is yet another way to decrease efficiency and cause lint buildup in the dryer hose.

When purchasing a new dryer vent hose make sure that it is made of metal and has the UL seal of approval. Metal hoses with the UL seal have the best fire resistance. Plastic and vinyl are not resistant enough to heat and can melt if the lint in the hose catches fire. Most building codes require a metal vent system and the fire hazard is the main reason for this.

If your dryer vent hose falls off it was not properly assembled or the clamp worked itself (with or without help) loose. Make sure that the hose is long enough and tighten the clamps. If the hose is not long enough buy a new hose. Don't try to find an extension trying to extend the length of the hose is another way to lessen the efficiency of your dryer. Check the owner's manual on your dryer to find out what the maximum length that the hose can be. You may need to move your dryer closer to the venting system to make the hose reach.

There are several types of dryer vent hoses plastic (bad), vinyl (bad), stainless steel (good), and aluminum (good). The hoses can be rigid or flexible. If it is a straight shot from the dryer to vent use a rigid straight hose. If you need to take a couple turns go with the flexible model.
