VIHOSE 12 Pcs 4'' ABS Round Vent Cover Plastic Soffit Vents Exhaust Bathroom Vent Cover with Built-in Fly Screen Mesh Air Vent Louver Grille Cover for Bathroom Office Home Kitchen, Black

These VIHOSE vent covers were exactly what I needed for a clean, professional finish in my home renovation project. The 4-inch size fit perfectly into my existing soffit holes, and the built-in mesh is a great touch—it keeps insects out without restricting airflow. The ABS plastic feels durable and lightweight, and the black finish looks sleek, especially against lighter walls or ceilings. Installation was quick and easy, and the louvers do a great job of directing airflow while keeping rain and debris out. I used them in both my bathroom and kitchen, and they've worked flawlessly. Excellent value for a 12-pack—highly recommended for DIYers and pros alike!

Very simple to install and very clean looking

I needed to vent some soffit to increase flow to our truss space. They looked a little cheap out of the box, but hey they were not expensive so… Anyway I installed them and they dont look bad. Really happy with the finished look and the amount of flow they give. They have directional blades so they can be pointed in the direction of the predominant winds which I assumed helped my issue.

Exactly as described, I got these for use indoors of a carbon exhaust setup and intake setup of ducting as I have pets that shed but also to adjust the airflow a bit better than just blowing straight out of 4" tube; these keep intake of unwanted large dust, debris and fur out and the ones on the exhaust side keep air from just blowing dust and fur back into the air, plus you also get a good 'finished' look to your ducting instead of just open tubes.

They added air to the roof but the flange needs to be wider. The hole necessary to drill through the soffit leaves little space for the mounting screws to hole it up there.
