How to Size a Bathroom Exhaust Fan

As the trend to larger spa-like bathrooms continues to gain in popularity, the need for proper ventilation becomes more important.

While many people are tired of their noisy and in effective bath fan – not many people know how to properly size a fan to their needs.

Read more below on the different methods of sizing the Bathroom Exhaust Fan.

Three Methods to Size a Bathroom Exhaust Fan

METHOD 1

This method works on the assumption that the goal for bathroom ventilation is 8 complete air changes per hour. Take your square footage x ceiling height to get the total cubic feet to be ventilated.
Example: Bathroom measures 10 feet wide and 12 feet long. It has 8 foot ceilings. So 10 x 12 x 8 = 960 cubic feet.

We take the cubic feet and divide by 60 – which is the number of minutes in an hour. We take the result and multiply by 8 (remember, our target is 8 complete air changes each hour). The complete equation is as follows:

STEP 1
10 ft X 12 ft X 8 ft = 960 cubic feet.

STEP 2
960 divided by 60 = 16.

STEP 3
16 x 8 = 128

So – we need 128 CFM of air movement to properly ventilate this bathroom. Assuming there is not and excessively long or twisting duct run to the outside – we would select a fan that moves somewhere around 130 CFM or higher. Examples would be the Panasonic FV-15VQ4 or Broan QTXE150FLT, both of which are rated at 150 CFM. If an inline fan is desired – the Fantech FR 110 would suffice.

METHOD 2

This method is a simple one – for bathrooms under 100 square feet. According to guidelines of HVI (Home Ventilating Institute) baths 100 square feet or smaller require one CFM per square foot of bathroom – with a minimum of 50 CFM.

So – if you have a 7 foot by 9 foot bath – you need 63 CFM. It doesn’t get any simpler than this. Most conventional ceiling insert fans, however, are rated either 50 or 80 CFM – so you will have to round up or down (rounding up preferred).

METHOD 3

This method of calculation is designed for bathrooms over 100 square feet and factors in the number of fixtures in the bath (toilets, showers, tubs). The rules are:

* Allow 50 CFM for each standard toilet, shower or tub
* Whirlpool and jetted tubs need 100 CFM

So – if you have 1 toilet (50 CFM), 1 shower (50 CFM) and 1 whirlpool tub (100 CFM) – you will need a 200 CFM Fan. The Pansonic
