How to Install a Dryer Vent That Keeps Out Pests

Cheap dryer vents with flimsy flaps break or clog up with lint and dirt, causing energy leaks and allowing access for pests. Keep them out with a dryer vent upgrade.

By the DIY experts of The Family Handyman Magazine

The new vent fits the same opening

A dryer vent with a loose or broken flapper invites drafts and mice into your house. And when clogged with lint, vents not only trap moist air but also become a fire hazard. Replace that old dryer vent with this sturdier unit that:

  • Allows easier outside access for vacuuming lint.
  • Provides a better seal to keep out vermin.
  • Saves energy by allowing waste dryer heat to radiate back into the house once the dryer’s cycle is complete.

The vent installs in 20 minutes (Photos 1 – 3). It’s available at home centers, hardware stores, and internet sites.

Interesting concept, the floating cup that obviously raises when the dryer is pushing warm air out, and otherwise settles down to keep unwanted things from getting into your house.

You can find this dryer vent on Amazon. It's currently $15.49 with free shipping.

Found one online and ordered it. It's a Lambro 289W Dryer Vent Closure.
Looking forward to installing it before winter. Hopefully, it will eliminate drafts and pest invasion as described. Will post comments after it's been in place for awhile.

How much back pressure does this vent add to the dryer vent system?
