A lthough some dryers use condensation to evaporate water and don’t require a vent, there are still many models that have to blow the exhaust outdoors. Sometimes, when you live in a studio or condominium, you might not have access to a proper outdoor vent for the dryer you use. Luckily, this problem is simple to fix with an indoor dryer vent. It works to eliminate the heat exhaust by capturing it and then releasing it into the air. Thus, it prevents the overheating of the dryer and spreads the heat and moisture to create a comfortable environment inside your house. Moreover, most models come with filters, lint traps, or screens that catch lint and other particles and maintain the air clean and fresh.

As clothes driers tend to increase moisture, you should use an indoor hygrometer to keep track of humidity and make sure it does not surpass the 55% - 60% threshold to avoid mold growth.

Frequently Asked Questions

Are indoor vents for dryers safe?
In terms of safety, they don’t pose a risk of fire but you might find the increased humidity to be a downside. The vents release warm air into the room, something that might be appreciated in the cold season, considering they can double as a heat source. However, the added moisture might cause mold and condensation issues.

How does an interior dryer vent function?
A hose goes from the back to the dryer into either a water reservoir or plastic housing that holds a mesh filter. The purpose of these venting kits is to release the hot air created while drying without also letting lint and fabric particles into the air.

Can the indoor vent be used with gas dryers?
All the major manufacturers specify on their products that they can only be used with electric dryers and not gas ones. The exhaust gas released while functioning contains carbon monoxide, so gas dryers only accommodate exterior vents.

How do you vent a dryer without a vent?
If your dryer lacks a vent, you need to keep the windows and doors opened while it runs. Also, a lint trap is essential to collect all the fabric particles and dust that are formed during the cycle.

Can I use spray foam around the dryer vent?
Yes, caulk or spray foam are great alternatives for sealing the vent gaps and preventing air infiltration.

Can I use a PVC pipe for a dryer vent?
No, improvisations are not advised as they can be dangerous. PVC is not recommended for venting due to the overheating and warping danger and you should use aluminum pipes that are more affordable, easier to install, and 100% risk-free.

Can I clean the dryer vent myself?
This procedure is not difficult and you can easily perform it yourself. Remove the lint from the mesh or the water reservoir by hand and vacuum the inside of the hose to remove allergens and debris.
