Hon&Guan Kitchen Exhaust Fan, 4 Inch Exhaust Fan Wall Exhaust Fan, Through Wall Fan for Kitchen/Gargage/HVAC System Ventilation-Ultra-Quiet 50CFM.

Small, super easy to install and looks amazing in my small bathroom. Very nice design look for my high-end space-not bulky or obvious like some of the other options. Fan is not supercharged, but it is effective and quiet. Perfect for keeping steam from building up during a bath, and keeping odors at bay after... Light is perfect! Brightened up the room and because it's LED, it won't hurt the bank. Very happy. Would recommend.

This is the third fan I purchased. Two are presently operational, but the failure of a prior fan was due to the fan getting flooded - not a defect. When the fan got flooded, it shut off without tripping the breaker. I need a couple 4" fans to run 24/7 at two locations of an out-building. I want just a little air flow, but not too much. This fan suits the bill. My only knock against it is that I wish it were a little quieter.

I should give less than 4 stars, but I’m not a jerk. I needed a fan that I can hardwire to a switch. The item information in the description says it is just that. Well, this is actually a plug-in. I cut the plug off and hard wired it, but I shouldn’t have had to. Anyway, the fan works well.

I got this fan for a through-wall vent application in a mobile home. Small room. Can't go through the roof and the walls are very narrow. I needed something that would work within those limitations. Bonus was this one looked really nice, matched the room itself quite well. Mine did NOT come with a built-in back draft damper. Built it a back plate to get the proper spacing from wall and installed it using a cheap outer hooded vent (you know, the really light-weight plastic ones with the really flimsy flappers that don't even have a spring) I had intended to put a spring-loaded inline back draft damper in the cheap hooded vent. However, this fan does not even put out enough cfm to lift the plastic flapper itself. I have a 23 cfm muffin fan that puts out way more airflow. I have decided to keep it instead of return it because of the looks of it and the amount of labor and materials I already have invested into this particular fan. But it is really expensive to be nothing more than a cheap plastic cover over a non-functional fan.

Mine seems quite weak. I'm not sure why. I thought about using two instead of just one, but it's so weak that I don't think it would really solve my problem of no bathroom ventilation. Much better than nothing, but I expected more air flow for the money. I'm not familiar enough with the volume/time rating to know if it works as advertised or not, but I can say I am a little disappointed, but not enough to return since I need ventilation badly. Perhaps if it were connected to a longer tube it would work better somehow, but I doubt it. Will delete review for discount or another unit. 3 stars overall. 5 stars for quiet. I haven't fully installed yet but I gave it 3 stars for that. 2 stars for suction power.

Exhaust fan works good. I used it in abuilding that stays closed up a lot. Very easy to install once you drill the hole with a hole saw. I added a 6' cord so I could use a wall outlet for power. A little noisy but keeps up air flow and no more moldy musty smell

This is really making a difference in my small bathroom. Sleek and low profile.Very happy with this purchase.

The media could not be loaded. The first fan was whisper quiet but started sounding like a lawn mower shortly after being installed in the ceiling. I just ordered a second fan because the hole is cut and I need something to fill it. Hopefully number two will hold up better than number one.
