Considerations When Choosing a Home Ventilation System

Homes are now built much more efficiently than they once were, making them far less costly to heat and air condition. That said, having proper ventilation throughout the home is now imperative in order to provide a safe and comfortable living environment. Broan ventilation fans provide the best solutions to ensure that contaminants are constantly removed from the indoors.

Eliminating excess moisture keeps your home dry and comfortable and can help avoid mold and mildew. Volatile organic compounds (VOCs) "outgas" from construction materials such as plywood, carpet, fabric, paint, adhesive, insulation, and other common items. Allergens, dust, cooking vapor, and what the kids bring home from school are more reasons why good ventilation is critical.

Sones measure the "sound level" of your fan

A sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the sone value, the more comfortable the environment. Sones are not decibels or volume, but rather how sound is "sensed." One sone is half as loud as two sones, and is equivalent to a quiet refrigerator.

Calculate the air movement necessary for proper ventilation

Air movement is measured in cubic feet per minute (CFM). To determine CFM requirements, first determine the size of your room. Measure and multiply the length, width and ceiling height of your room to determine cubic footage. Then use the multiplication factor of .13 and round up to the next "ten." Here are three examples:

Example 1: Bathroom with 8' ceiling: 7' wide x 9' long x 8' high x .13 = 66. Select a bath fan with at least 70 CFM.

Example 2: Bathroom with 9' ceiling: 10' wide x 9' long x 9' high x .13 = 105. Select a bath fan with at least 110 CFM.

Example 3: For a bathroom with a vaulted ceiling, use the average ceiling height at the wall and the peak: 8' wide x 12' long x ((8' at wall + 12' at peak) / 2 = 10') average height x .13 = 125. Select a fan (or fans) with at least 130 CFM.

Broan 10" Vertical Discharge fan.

Since this unit discharges upward, you'll need an unfinished attic, or similar space, directly above the fan. I installed a Broan 472 Backdraft Damper/Reducer on top of the fan, which reduces the fan's top 10" opening to 8"; used 8" galvanized duct work, and routed it through an 8" roof vent [also] with a damper. The fan itself contains NO back-draft damper.


- It works acceptably.

- Painted sheet-metal steel body and mounting brackets, are strong.

- Grille looks good.

- The fan assembly has an integral external electric box to receive 14/2 cable from your wall switch. The fan motor has a 4" cord which plugs into a dedicated "receptacle" inside the housing, enabling the fan motor to be replaced by simply unplugging it and removing two mounting screws.


- The rushing air through the fan is anything but quiet. This is because the fan blade is attached directly to the motor shaft, turning the fan blade at high speed. Fans using lower-speed belt-driven blowers are much quieter.

- The fan motor doesn't work with a multi-speed or variable-speed switch. I.e., connected to a 3-speed wall switch, the fan only comes on when the switch is set to high.


- I made a plywood and 2x4 frame to support the fan assembly, using the built-in brackets to support it. I cut a 10-3/8" round hole in 3/4" plywood, set the fan housing just below the finished ceiling, and used joint compound to feather the rim to the ceiling level (and seal the gap around the fan housing).

We installed this fan in our bathroom remodel in 1996. Awesome choice. The room is only 10'x8' and it *totally* protected the finish on our custom cabinets and the painted walls. After 12 years, not One area of steam damage or mold. The motor finally gave out and I can't wait for the new one to arrive tomorrow so I can have another 12 years of a steam-free bathroom :O)

I purchased this from Lowes and installed it in an interior bathroom with no windows. It replaced a smaller, less powerful, and quieter bathroom fan. Reason for the upgrade was that people (my son) would take very long showers (my 50G hot water tank would empty). As a result my bathroom ceiling would get a lot of mold on it. After repeated scrubbing and painting efforts I got a more powerful fan - the Braun 505B.

It is an 8 inch vertical updraft fan and is loud. Some people like a loud fan because it provides audible privacy when taking care of business and this fan did the job. It replaced a fan with a 4 inch side discharge vent. This required a 8" to 4" funnel to allow the metal exhaust vent hose in the attic to properly attach to the fan. I have used the fan with and without the funnel/vent hose attached to the 8" fan vent. There is a noticeable increase in ability to vent the moisture out of the bathroom when it is vented only into the attic, much less so when vented to the outside via funnel/vent hose. I would have to use an 8" tube all the way to a new exhaust vent on the roof of the house to solve this problem. Not worth it. Moisture in the attic when living in a desert did not seem like a problem to me but I'm sure some building code was being violated. My evaporative cooler also vents into the attic. Go figure.

Because the fan is powerful, you could feel the air flowing under the bathroom door. If the fan was on while taking a shower the bathroom mirrors would not steam up. As a result people (my son) would only turn on the fan AFTER getting out of the shower. He would then walk away from the bathroom with the fan on - thus wasting electricity and heated air in the winter time.

I live in a 24 year old mobile home. And as you out there in my position know it is HARD to find mobile home parts. So when our 20 + something fan broke for the guest bathroom we were shocked to find that Home Depot and lowes both didn't have one that would work in our home. We have a vent that shoots straight up (vertical) into the roof. And most vents now have a left or right (horizontal) curvature to the vent. So when we found this one we were thrilled it was the right kind. One that just shoots straight up. Now the fan is a little louder than we hoped for however after careful consideration we are glad it is. Have you ever been to a house where the guest bathroom is so close to the main family room you don't feel comfortable, thinking someone can hear you using the restroom?? Well problem solved. This fan is just the right amount of loud so you don't hear a thing. And our house HAS a bathroom right off of the living room---to close for comfort. So in my opinion this fan is perfect. The outside of it is beige/cream not white. And the base is pretty wide at 8inches. But fits perfectly. Again, it is loud but I'm sure my guests appreciate the loud "cover" for them to do what they have to do and not be embarrassed. I have had several get togethers and almost everyone has used the fan to mask their private affairs. Glad I got it. Hope this helped.
