I agree with the second opinion as I have tried it.

There are straightforward ways to vent your dryer. When you don’t have a hose outside, you can use a lint trap or your window to let gasses escape. These are some really easy ways to vent the unhealthy gasses. But if you want the best results, you need the dryer vent outside.

Is it Risky to Use the Dryer Without Venting Outside?

No, it’s not risky if you know how to vent it properly. Some people think it’s not even possible. But it’s possible to use the dryer without the vent outside. The vent is for the lint and other gasses to escape from the dryer and your surroundings. It is preferred to use the vent for the best results. 

The gasses in the dryer are really bad for your health. You can identify the smells when you get one.

3 Ways Vent a Dryer Without a Vent to Outside

There are three ways to use the dryer when there is no outside vent. Below I have explained the ways of each method. 

1. Using a Lint Trap in the Room

Lint traps are detachable filters which seats behind the dryer at the end of the flex vent. Most indoor lint traps use one filter. But some use two. Also, some might use water. They filter the air of the lint particles that dryers produce.

You can place it on the wall. Or you might leave it on the ground close to the dryer. 

If there is a clog blocking the vent. There are a few indoor lint traps that also have safety vent flaps. The vent flaps open automatically to expel exhaust. 

The disadvantage of indoor lint traps is that they take up a lot of space.

Indoor lint traps have some other disadvantages. They frequent filter cleaning in addition to the standard lint trap inside the dryer. In addition, some lint particles (and humidity) may enter the indoor air. Which would not occur in a regular arrangement.

If you’re thinking about buying a lint trapper for your house. You can give the given below, lint trappers a try. They are really good at their job.


These are some of the really good lint trappers. Also, they are really durable. So they should last for a long time. 

An important tip. Don’t use the lint trapper and the dryer from the same outlet. The wire might take too much load. 

You should also use a surge protector for your washer and dryer.

2. Use the Window to Vent Outside

This method uses the window to get the gasses outside.

If you’re thinking of making it permanent. It’s better to get a window dryer vent kit. This will allow you to use it at the bottom of the window. But you do need to cover the sides of the window. This will make sure outdoor air from going inside.

It looks similar to a portable A/C window connection. Only the dryer vent hood has a flapper.

But, if this is a temporary situation. You can put the hose out the window. You just need to stuff the sides of the window with something. This will prevent air infiltration.

Even though this is not the best-looking method. Alternatively, you can add the vent to the existing ductwork. 

3. Use a Dryer Which is Ventless

Getting a new ventless dryer is the third method. Americans may not be familiar with ventless dryers, but they are very popular in other countries. 

Ventless dryers don’t use a vent. They redirect all the air inside the dryer. This filters all lint. 

As the moisture from the garments passes through an inside heat exchanger, it condenses (turns into water). 

These dryers are good at their job. But they take a long time to dry clothes compared to traditional dryers. In addition, ventless dryers have a smaller capacity than conventional dryers.

Why You Should Vent Your Dryer

The one job of the vent is to remove the lint from your dryer. When you are drying your clothes in the dryer. The humidity is high there. The vent releases some moisture outside.

This also prevents mildew from growing inside the dryer. Mildew grows when there is too much humidity, and removing mildew is a hassle.

The vent also releases some of the gasses in the dryer. Your dryer produces carbon monoxide when it is running. The vent releases the gasses, so it doesn’t affect your health. 

So using the vent on the dryer is essential. And if it is available, you definitely should use one. They are with your dryer for a critical thing to remember.

Can I do a DIY indoor dryer vent?

You can attach a hose after wrapping it with aluminum foil. After that, put the hose in a bucket of water. This will catch all the lint.
