Decide if you want ur exhaust fan to run on a timer or on a

switch. Switch-based fans turn on & off like a light, using a switch on

specific moments (such as when cooking or using the toilet), while the  
latter provides a more thorough & regular recirculation of the air.  
 
Step 2Measure the volume of ur kitchen or bathroom. You can to this with a  
tape measure: Multiply the room is width times its length times its height  
(in feet).  
 
Step 3Determine the amount of cubic feet per minute (CFM), which is the  
airflow required to exchange the air in the room eight times per hour,  
which is the recommended efficiency of any exhaust fan. You can determine  
the CFM by dividing the room is volume by 7.5.  
 
Step 4Check the CFM on any exhaust fans you select: It should be listed on  
the box. You want a fan whose CFM is equal to or larger than the CFM of the  
room you intend to use it in.  
 
Step 5Compare the sound level of various exhaust fans. You usually want to  
select the quietest fan possible. Fan noise is measured in sones, usually  
ranked from 0.5 to 4.0 & listed on the box. The lower the sone, the  
quieter the fan, so look for fans ranked at 1.0 sone or below, if  
possible.  
 
Step 6Select a fan which can be installed with screws rather than nails.  
Nails have a tendency to vibrate & can come loose after time. Screws will  
hold the fan more securely for a longer length of time.  
 
Step 7Choose a fan that matches the aesthetics & décor of the room where  
you intend to install it. This is purely a matter of taste & the amount of  
money you wish to spend. Exhaust fans come in all manner of styles &  
features, & you can always find one to match the specifics of ur room.

If you have your dryer hooked up to a vent hose and it goes

hooked up to the long hose going outside, then forget about it.
