4 in. Eave Vent for Bath Exhaust is rated 3.8 out of 5 by 13.
Rated 3 out of 5 by from Nice idea, fits in small places, but has a problem. All houses have dust, so what happens when moist air and dust get drawn through the fan and out the vent? Those thin vent louvers clog with dust. One day I realized the bathroom was getting fogged easily while taking showers. Got up on a ladder outside and those thin and dense louvers were clogged. Even with a high power shop-vac I had trouble cleaning it. I ended up using a long thin blade to pluck out all the dust as best as I can. Works better now. I think I will have to replace this with a spring loaded vent, but those are large and require about 16-18" sofit and 6" of clearance to install since they are meant to fit 4, 5 and 6" ducts. Have to figure out something. If this vent is all you have room for, great. If not, be prepared to get out on a ladder to clean it out every so often. One last thing is since there isn't a large flange, you need to drill a hole the perfect size. Zip ties don't work out to attach the duct because of that. I ended up using metal HVAC tape which worked perfect for a tight press fit.

Rated 5 out of 5 by from So far so good... Installed in a wide perforated vinyl soffit right outside the bathroom window. Louvers allow pointing the exhaust away from the house; very little flow resistance compared to anything with a damper (the bath fan already has a built-in damper; another one at the exhaust wouldn't do a lot). If duct resistance is also low, the moist air will be blown clear of the house, preventing re-uptake into surrounding soffit intake vents. NOTE: The stop flange is VERY narrow, and there's nothing on the plastic collar to lock the vent in place on the soffit- so 1) take care to avoid cutting the hole bigger than it needs to be, and 2) use a good caulk-like adhesive around the flange, then come up with something to hold it in place until it dries. I used aluminum duct tape around the perimeter; that seemed to hold pretty well. GOOD LUCK!

Rated 5 out of 5 by from work great but cut right size hole These workngreat for hooking up the bath fan exhaust to. Just be sure you cut a hole in your soffit with a 4" hole saw. 4 1/8" will be too large.

Rated 5 out of 5 by from Low resistance soffit vent "slats" far enough apart for low flow resistance but unlikely to clog. No damper (fan already has one and would impede flow). 4" hole saw worked great. Great product.
