PreVent-It 4 Inch Soffit Vent for Bathroom Exhaust Fans, White, 1-Pack

A well made and sturdy vent. Build in baffle prevents drafts from entering. Looks good and functions perfectly. Very easy to install. The unit is a little large but I had the room for it. Ended up looking great. Very pleased.

This was so easy to install and it looks great on my soffit. When my bathroom fan is turned on I can easily feel the airflow coming from the hose. It's made from very sturdy material.

They product seems like it is durable and will stand the test of time. It seems more durable than the flimsy plastic vents you buy at the store. My house is 17 years old was missing a few soffit vents. All my soffits are vented for air flow so this is the only product I found in the market that will push the airflow away from your soffits. I ended up buying and installing 5 of these and they were pretty easy to put in. My only feedback would be to provide some longer screws. Sometimes I was drilling into the slots where the soffit overlaps and I either had to drill at an angle or jam it up in there to hit some soffit material. Other than that, they are a great idea and solved my problem. 5 stars would buy again.

Works great to push the air away from soffit. Matches my black soffit. easy to install. I have a 2 ft overhang, so this works and if ice icicles do form, there is room so it doesn't block the vent

Best unit I was able to find that checks all the boxes I needed. Installed as expected. An unexpected “like” is the front nozzle can be removed separately to allow inspection and clean-out if needed (vendor should highlight this in a photo). My only issue is the door flap uses plastic integrated pins (like a dryer exhaust vent flap) which I question for long-term strength. Be sure to mount flat as any stress will bend the flap area and not allow it to move freely.

Great product. Easy to install in my soffit. Product comes white but I spray painted it tan to match my soffits. Came out great after painting.

This is the go to bathroom exhaust vent is you have to install it under your soffit, especially when the soffit ventilation is right there by your install. Designed to channel your moist bathroom air away from the perforated soffits so no moist air returns to the attic. Easy to clean vent baffle and screen in the front. A bit more expensive than some of the simpler, smaller vents but well worth it. NOTE: If your venting through the outside wall, there's no real advantage to this vent. But if you're going through the soffit, get this product. You'll be glad you did. Remember in cold climates to insulate the duct from the fan to the vent.

Worked as it should, solid build quality and worth the money. It fit the vent hose for my aftermarket bathroom fan and looks better than expected mounted on the soffit. I would recommend and buy again if needed.

The design is very effective and as far as I know there is nothing like this in the UK market. However this is ridiculously over priced for what is a cheap plastic product. There is a back draft flap but I'm not convinced it will be either robust or effective - the fit is poor and for the price there should be zero friction at the pivot point.

sturdy and fits

Évans de chambre de bain pour sophite Tres peut de model font la job mais se model travaille tres bien pour l'installation sous sophite Pour ceux qui installe leur sortie sur le toit avec une trappe approprier c'est tres bien mais avec quelque bordé de neige tout est pris dans la glace et ca ne fonctionne plus et vous étes due pour une petite visite sur votre toit

Good idea but it's not well done... the anti back draft system can get stuck half way.

Needed this after constantly having ice dams forming around the vent through the roof all winter. Venting heated air through a roof that can get up to 3’ of snow is the dumbest idea ever. Many people worry about the moisture getting in the attic with this vent but the design clearly prevents that. Moist air would clearly rise up over the gutters. I occluded the two rafter vents on either side of this vent as well just as a precaution. If you wanted to you could also put non vented, solid soffits on either side of this vent as well. My flapper is stuck for some reason, I was probably going to remove it anyway, moist air is going to cause ice around the opening all winter and will freeze shut the flapper anyway. But going up there once a month to take the easily removable cap off and clear ice is a lot better that chipping away at ice dams and the water damage that comes with it.
