Best For wall: Deflecto 4 Inch Hole Cover

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate cover. The deflecto 4 inch hole cover is exactly that - it's a simple cover that hits all the right notes. This product is obviously a very simple concept, with plastic louvered doors that swing open or closed depending on the air flow from the dryer vent. It has a 7/8" deep collar to mate up with 4" duct work. The center flap stays up when air blows through the vent. It will fit flush as long as your wall is square.

The multi louvered vent is easy to instal and easy to see that it is working and closing fully. This color is great for a brick house. There is no protruding extension for the duct, but it does have a circular piece that fits with the duct that this picture doesn't show. This is a very solid unit and easily stands up to the pushing and adjustments to get it into place on an older house.

Best With fly Screen: Honguan 4 Inch Hole Cover

Buy on Amazon

The honguan 4 inch hole cover is capable of outshining several other cover featured in this list in overall features for the price point. It fits with modern decor and additionally it is great as a boat vent. It slides in to the vent with an existing vent 4" duct. This turns the 4" nominal diameter flow into the equivalent of less than half that and causes the exhaust fan to kick excess air back into the room. The fins position the vent in the (larger than the vent) hole you make in the wall or, perhaps, into the tubing you are attaching to it, but that leaves it so you or anyone could just rip it out of the wall with ease.

This vent has smaller holes so that bugs can’t get into the house. It is easy to clean and maintain. The screen will sure keep out bugs but a dryer will clog this thing up in a couple of uses.

Why We Like This:

Perfect and fit the hole with the 4" hole saw
Fit and finish is really good
