No-Pest Vent, 4 Inch Soffit Vent Cover, Great for Bathroom or Dryer Vent Cover, Patented Dual Door Design Prevents Birds and Back Drafts, Highest Efficiency Soffit Exhaust Vents on the Market (White)

I give this a five star for several reasons. It works great as advertised, was an easy installation and a big on is it is made in America!

This is a quality built vent, not cheap plastic. Use this for a bath exhaust in a remodel of our 100 year old house. Soffit was the only option and this worked perfectly. Havent had any issue with bugs or debris blocking the flaps and it stays closed like it should.

Nicest vent we have purchased. Works well. Fairly easy to install. Looks nice outside. Great for high windy area.

I'm giving it 4 stars, because it is a nice vent.... however..... The vent is not designed to have a standard 4" flex duct slipped over the collar. The collar is designed for some kind of quick-connect fitting that's already present on the end of the duct to slip inside the collar. That's why the collar is too short and why a normal flex duct won't slip over the end. I made do during the install because I had the old vent and cut off the plastic collar from that. Used a utility knife to pare away the quick-connect flanges, slipped one in the other and used a couple self-tapping screws to hold it together. Be warned. Zoom in to the photo and you'll see the slots for the quick connect.

I bought this to replace the dryer vents the inspector had installed for our two bathroom vents. They face down so the dryer vent louvers would always be open allowing air and pets to get in. Note, you may find the doors come undone/unattached easy when not installed, that is not a problem once the vent is fully installed! These are great as the doors only open when your fan is running/pushing the air out, when close when the air is off. They also match our home’s paint perfectly!! This was a big find!

The connection to these is 4 1/4 in diameter. 99% of the exhaust hose will not fit these.

Clever, simple design to prevent critters from entering your soffit vent. I appreciate the double layered door which prevents rodents from lifting it up and crawling inside, which was the problem we were having with lesser vent covers.

This thing is the best! My Home Depot had nothing like this (only ones for protruding out of walls), and this one is just what I needed. It worked so well that I am going to get another one for the bathroom vent (I used this one for the dryer vent).

Facile a installer

Worked well

Works well in canadian winter climate for bathroom exhaust fan. Considerably reduces back draft compare to simple grid.

Product looked nice and functional . Upon install , multiple parts cracked and flaps fell off . They were not expensive but cost me my time to fix and refit the product .

Constantly freezes shut. Very annoying.
