Here's a quick rundown: If you can't vent your dryer outside, there's a risk of fires due to lint buildup, a chance for mold to grow, your laundry room might get too hot, and drying times could increase, possibly causing damage to your clothes and higher energy bills.
Lint Buildup and Fire Hazard
This hot air also carries lint shed from your clothes. A vent hose channels this hot, lint-laden air outside. Without a vent, lint builds up inside the dryer, around the drum, and in the exhaust path. This lint buildup is a major fire hazard.
If you really just can NOT vent to the outdoors, you can set it up where the vent hose runs into a large container of water. The water will filter out most of the lint as the air bubbles through. It will still increase the heat and humidity in your home, though.
Fire Hazards: Running a traditional dryer without a vent leads to dangerous lint buildup, increasing the risk of fires. Moisture Damage: Without proper ventilation, trapped humidity can encourage mold and mildew growth, affecting indoor air quality and structural integrity.
You can take a bucket fabricate a top, cut a hole in it for the vent pipe, drill many holes around the top for the air to escape then put some water in the bucket with about 4--6'' below the end of the vent pipe? Do not submerge the vent into the water. The exhaust simply blows over the water.
Venting a dryer vent indoors can introduce dust, lint, and other pollutants into your home's air. Laundry detergents and dryer sheets often include chemicals that are dangerous to breathe in on a consistent basis.

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.
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.
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.
There are two types of ventless dryers: condensing dryers and heat pump dryers. Though these appliances function differently, they both can be installed without ventilation.
Some dryer vent installations also have an external lint trap, which is also known as a secondary dryer lint trap or a 4″ In-Line Dryer Lint Trap.
Some places or building codes may not allow indoor dryer vents due to safety concerns, so check your local rules.
In a pinch, you can vent your dryer out a window. Someone might do this if they're building a house and currently waiting for professional dryer installation or if they own a portable clothes dryer.
Ventless dryers come with a few common disadvantages. These include a smaller load capacity, a higher initial cost, and potential humidity issues.
Moisture collects in the tub and is removed from the unit through the drain pump. Process air (cool dry) exits the condenser. Process air (cool dry) enters heater and is reheated. Process air (heated) re-enters drum to absorb more moisture and dry load.
Mold Growth: Dryers release moisture during drying. Without proper ventilation, this moisture stays inside, creating a perfect place for mold and mildew. This can lead to breathing issues, allergies, and damage to your clothes and home.
Exhaust from gas dryers must be vented outside because it contains carbon monoxide.
Even if the dryer itself is in good condition, clogged dryer vents can cause a fire that can quickly spread to the rest of your home.
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.
Consider an Extra Dryer Vent Outdoor Lint Catcher
These are readily available at hardware stores and are easy to install. Just remember to empty them regularly to prevent them from becoming clogged themselves!
One solution often considered is the installation of an indoor dryer vent kit. This method allows residents of apartments, townhouses, and condominiums to vent their electric clothes dryer indoors, but it comes with its set of advantages and disadvantages.
In most homes, the dryer vent runs horizontally through the wall to the outside. You just need to go to the place on the exterior of your home where your laundry room is, more or less, and you'll usually see the vent's exhaust on the wall nearby.
These convenient devices significantly reduce the time it takes to dry clothes, but their installation and operation come with certain requirements and considerations. One of the primary questions that arises with electric dryers is whether they need a vent to the outside. The answer to this question is Yes.
