Panasonic FV-0510VS1 WhisperValue DC Energy-Saving Bathroom Ventilation Fan, Quiet, Lowest Profile Energy Star Certified Ceiling Mount Fan

Easy to install. DC motor. 3 speeds selectable: 50 cfm silent, 80 cfm semi-silent, 100 cfm noticeable sound of whooshing air but very localized to fan area ( motor is silent, whooshing air makes noise). Yes as per instructions it takes a few (5) seconds for fan to turn on after flipping switch. We run it to vent basement at 100cfm and it even pulls air from first floor down our staircase. In conjunction with a dehumidifier and this fan, our basement is more comfortable as the dehumidifier pulls cool damp air from floor level and blows warm air (from heat-exchanger and fan motor) upwards and this exhaust fan takes it outside. We have replaced all builder installed fans with similar DC motor ones within this price range. Would buy this for bath fan replace so it can be run at full speed to remove heat in house during summer and at a low speed in winter. CON: exhaust pipe is oval and adapter not available in Canada: work around: use 4 inch aluminium elbow: tape seams of elbow with metal tape (or else joints will come apart) and then gently squeeze one end until it matches oval shape, insert and tape together to fan.

This fan is impressively quiet while still moving a lot of air. It makes a huge difference in clearing steam from the bathroom after showers without being loud or distracting. The slim design made installation straightforward and it fits perfectly even in a smaller space. Build quality feels solid and it runs smoothly without rattling. I am very happy with this purchase and would recommend it to anyone looking for an efficient and nearly silent bathroom fan.

Excellent product. I have bought 5 of these in the past few years and they are all great, quiet and well built. I highly recommend them.

The 70 sq.ft. bathroom in our house had a 70 CFM Broan installed which was quite loud, but more worrying was the amount of moisture on the ceiling and running down the walls after a shower. Bought this one based on the reviews and the selectable CFM’s. It installed fairly easy since it all comes apart, just had to cut a bigger hole attach the duct and wiring, snap it back together and screw it to the joist with some extra wood support I installed for rigidity. I set it at 80 CFM and its much quieter than the previous fan which was 4 sones. More importantly there is no more moisture collecting on the ceiling and walls!

Due to the nature of my ceilings in my bathroom, a ceiling mounted vent fan was not an option. So I planned on wall mounting a ceiling fan but couldn't find anything that would fit in a 4" wall cavity. My friend who owns a contracting company told me about this fan and how it has a smaller profile. I have to say it fit perfectly with no hassle at all. The availability to select 50, 80, or 100 CFMs is a great feature given that there aren't many low profile vent fans out there. The noise levels at 50 and 80 are very quiet. However, at 100 as you can imagine it gets a little louder. My wife and I actually decided to set it to 100 CFM because 50 and 80 were too quiet. The noise of the fan offers some... "privacy" when using the bathroom. Thankfully, to change the CFM is extremely easy, simply remove the cover and flick a switch. The general install was straightforward, particularly if you are handy. A few screws secure it to the stud, wiring is as basic as it gets, and the cover leaves lots of room for error when drywalling around it. My only slight concern would be the shape of the duct. I used zip-ties along with aluminum duct tape as you have to bend the ducting to fit the low profile oval shape. I understand that this feature must exist to fit the 4" space, so I can't complain too much. Overall, if you require a vent fan that can be used in tight spaces, this is a great option.
