When a dryer vent becomes disconnected the warm moist air terminates wherever the damage to the vent has occurred. Air from a dryer vent provides a conducive condition for mold and other fungal growth. Because attics and crawlspaces are unfinished areas of a home, they are already more susceptible to mold growth.
Growth of Mold
Improper venting of a dryer typically results in moisture being deposited in various areas of the room. Moist air serves as a breeding ground for mold-and-mildew when it condenses on different surfaces. You want to exhaust the warm air outside the home rather than indoors to properly vent your dryer.
It's fine. You'll have a good amount of humidity and possibly some lint in the vicinity, but nothing that will cause damage for the few times your doing it.
It is not safe. Vent hoses are necessary for dryers to operate properly because they allow heat, lint, and humidity to be vented outdoors. When a dryer is used without one of these vent hoses, moisture and lint can build up inside the appliance and even cause a fire.
Secure Vent Hose with Clamps
If your vent hose repeatedly disconnects, it's likely due to loose vent clamps. Use clamps to tightly secure the vent hose to both the dryer and the vent opening. Ensure a snug fit to minimize the chances of the hose coming off.

First, check if the vent hose is in good condition. Look for: Dryer vent hose damage: Tears, holes, or cracks will weaken the hose, making it more prone to falling off. Wear on the hose clamp: Dryer hose clamp damage could prevent it from holding the hose tightly enough.
Longer Drying Times: A dryer without proper venting struggles to remove moisture effectively. This means your clothes take longer to dry, leading to higher energy bills and potential damage from over-drying.
And perhaps more worrisome than mismatched socks is the risk of fire that such an incident creates - a sock that becomes stuck in the vent limits the ability of the dryer to eliminate hot air, which can quickly turn lint into kindling.
Without a properly installed vent, a clothes dryer won't perform well and can be a fire hazard. Figuring out how to attach a dryer vent isn't complicated and you can do it yourself. All you need are the proper tools and an eye for detail.
Per the requirements of the International Residential Code, Section M1502 (2009-2021 IRC), the clothes dryer exhaust duct should be a rigid or semi-rigid metal duct made of galvanized steel or galvanized aluminum with a smooth interior finish and a duct diameter of 4 inches.
A ventless dryer is a type of electric dryer that doesn't require a vent to the outdoors. Traditional dryers use a vent to release warm air outside, but ventless dryers operate differently, relying on a heat exchanger or heat pump instead. They typically come in two types: condenser and heat pump.
A damaged or poorly maintained dryer vent can lead to potential fire hazards, increased energy consumption, and reduced drying performance.
It works just fine and never gives us any trouble. We just fill it with water and connect the dryer duct. The water in the bucket collects the lint, and we change the water from time to time.
Wrapping Up. To sum it up, while it's technically possible to run a dryer without the vent hose, it's strongly advised against due to safety hazards like gas buildup, increased fire risk, and potential health issues.
If your dryer vent is blocked, all of this built-up lint can become a fire hazard. The heat from your dryer could cause the lint to combust, potentially catching your dryer and parts of your home on fire.
You'll want to decide between vent clamps or foil tape to secure the dryer venting to the dryer exhaust outlet and wall vent. If you're using a vent clamp to secure venting, place the vent clamp loosely on the edge of the vent hose and slide the edge of the vent hose over the wall outlet.
In back of most dryer units is a short 4-inch diameter exhaust. This exhaust connects to dedicated ductwork inside the wall through an aluminum elbow or other pipe. Hot air travels along these metal pipes to eventually emerge through an opening on an outside wall of your house.
The most popular solution is to vent your dryer through a nearby window. This option can be a lifesaver for people who have no other reasonable option and still wish to enjoy the benefits of having a clothes dryer right in their home.
Instead of heating your home with warm, humid air, the dryer vent flap on your external wall allows the exhaust from your dryer to evacuate your room. The flap prevents the outside elements, as well as small, uninvited insects or other creatures, from entering your home.
Even if your washer/dryer setup is in the middle of your home, your dryer should vent to the exterior on the shortest, straightest path possible.
Exhaust from gas dryers must be vented outside because it contains carbon monoxide.
