Overview
The Deflecto RVHAW4 is a 4-inch white replacement dryer vent hood with a removable bird and pest guard and a one-way inner flap. It's a wall cap meant to replace a damaged or mismatched existing dryer vent cover on standard 4-inch ducting.
Fit is straightforward on siding, brick or cinder block exteriors, with the metal tube pressing into the plastic body during install. The inner flap is thin aluminum, and a few buyers taped it to keep it fully closed rather than relying on the flap alone. At least one buyer reused it on a non-dryer duct of matching size.
- 4-inch diameter, wide-mouth opening
- Removable bird and pest guard
- One-way flap closure for airflow control
- Weather-resistant white finish
Who it's for
Fits anyone replacing a worn or ill-fitting dryer vent cover, especially where the exterior finish, such as brick, siding or cinder block, needs a cover that seats flush. Not the pick if you want a heavier-gauge hood than a basic aluminum flap.
Pros and cons
- Fits standard 4-inch dryer duct openings easily
- One-way inner flap blocks drafts and pests when idle
- Removable bird and pest guard
- Thin aluminum flap sometimes needs tape to stay closed
- Critter guard grille can sit loosely instead of snug
Performance notes
The one-way inner flap is meant to open under dryer airflow and close afterward to block cold air and pests, and the removable critter cage keeps larger animals out of the duct. Installation is a snug push-fit into the existing duct opening rather than requiring hardware, though the flap and grille can each need minor adjustment to sit fully closed or snug.
