Question: I'm thinking of installing one in a tiny house to exhaust cooking odors and grease.  How have you dealt with grease accumulation over months/years?
Document: As this has a 70 CFM rating and is a member of the 'Whisper' series, I expected it to be a bit quieter, but still works like a charm and a previous one I ordered has been in service for over 4 years.
So if used in attic, might want to get two...one for inflow and the other for outflow...little attic air vent screens will hamper the exhaust of hot air.
I'm very satisfied with all the Panasonic venting fans that I've ever purchased: they are not toys yet they operate so very quietly. This one is a version made for wall installation and,in particular, it was relatively easy to adapt for my use in an 8" square duct.
Most fans don't run 24/7 but this one does. All I do is blow it out once in a while to prevent dust and hair buildup. (We have 3 large, long-haired dogs and 2 cats. Hair finds its way everywhere.) I've had this fan for only a few months but should get long life from it.
This exhaust fan is the most awesome one we have ever installed! It's in our kitchen. It's so quiet you don't even know it's on. Air quality has improved 100%. We even installed an on / off switch so it doesn't run at night. Five star review!
It is extremely quiet, and seems to move an appropriate amount of air. One thing to note is that the exhaust duct is 8&#34; - a heck of a lot bigger than most bathroom fans. Make sure that'll work for your application.
Nice fan and runs quite compared to the old one. Installation through the wall required some dry wall modification but I was putting it in a 40 year old house. Amazing how much air it moves for how quite it is. I am going to purchase a ceiling model for another bathroom.
Installed this at a rental house which is an older house. Requires a very big hole thru the wall which seems like overkill and if you are not prepared to do so find a different unit. It does however work very well and is very quiet. It is rather expensive also but if you can't use a ceiling unit this is a very nice looking fan and was rated very good which is why I got this one.
The fan is so incredibly quiet. We use it in the bathroom. Since it is wired to the light switch it helps that this fan is so quiet. You barely know that it is on. Installation is fairly simple for some one who is somewhat handy. Follow the instructions and you will be fine. We have another fan in another bathroom that came with the house. It is going to be replaced by one of the Panasonic Whisper fans. It also does a great job of removing moisture from the bathroom.
It's time I wrote a review of this one. I've had it for several months now and it's great. I have a wine cellar with my cooling unit in a hallway that I thought would have plenty of ventilation, but it didn't... The warm air from the cooling unit stayed on the ceiling and I bought a SunCourt Thru-Wall Room to Room Fan to suck the warm air out to another room. It worked fine. However, it was REALLY noisy.
