Door Vent for Interior Doors 16 7/8" x 3" - Two Sided Door Louvers | for Bathroom, Cabinet | Plastic air Vent Grille | Outer Dimensions 17 3/4" x 3 5/8" for 16 7/8" x 3" Opening (White)

This is a well made product that is designed so the two sides fit together securely so it lines up properly. The air flow is better than the vents with the cardboard insert. It comes with a pattern to help cut the hole and has different length screws for different door thicknesses. This is better than many of the more expensive vents. I used it for a bathroom door and it has allowed the exhaust fan to work much better.

Pool pump house door vents! Great way to get fresh air in. Water tight and rain stays out👍

This is exactly what I was needing. Fits perfect in my space and was super easy to install. Only complaint is that it’s plastic and feels like it could break if bumped too hard etc but overall very pleased.

Allows air to flow when door closed, work well.

Easy installation , the template was a huge help

The template for the cuts is heavy stock paper making it easy to trace, even on a textured door. Provides a centerline making alignment easy. Links to a helpful video provided but weren't needed. Multiple options for thickness provided making it possible to install in many places. This should help our bathroom breath a little better both when the door is closed for privacy but also when the exhaust fan is on for showering. Door closes more firmly now too since there's no air pressure generated. Louvers can be counter aligned to ensure privacy as well. Be sure to use a level determining your positioning; this wasn't on the recommended tool list but should be. A version with a damper would be great so you could open or close multiple vents to work for seasonality of room air temps.

I took the door outside, marked it with the provided template, drilled corner holes for the saber saw, cut out the opening and simply mounted the new louvers.Helps vent the shower steam from a small bathroom and is rust proof.As the door is already white, I didn't have to paint the louvers.Seems a bit pricey for a molded plastic product, but it works very well.

Had a bathroom with poor ventilation. The vent worked, but couldn't get enough recovery air. Shower steam disappeared once this was installed. The materials aren't the best. It's plastic, so you know what you're buying. You need to be moderately skilled to install it, mainly cutting the hole in the door correctly. It does the job, but minus one star for the quality of the plastic.
