What's Living Inside Your Exterior Vents?

Most homeowners never think about their exterior vents — until something gets in. No Nest helps keep unwanted critters out while maintaining the airflow your home depends on.

Blocked vents aren't just inconvenient—they can become expensive.

Thousands of residential dryer fires occur each year in the United States, resulting in approximately $35 million in annual property damage, with blocked exhaust vents recognized as a contributing hazard.

Pro Tips

  • Install when the vent surface is smooth for best fit.
  • Check local building codes for any vent-screen requirements in your area.
  • For double-wall vents, install the guard on the inner housing.
  • Clean the guard every 6 months with a brush to remove lint buildup.

Why Homeowners Trust No Nest

Designed by an industry expert

As a HVAC industry leader, I created No Nest after seeing the damage that birds, rodents, and nesting debris can cause to homes. I knew there had to be a better way to protect vents without restricting airflow.
