need help on the smell

if you allready have the fan then your best bet is to just buy your self a carbon filter there like £20 dude which is allmost what you will spend on buying + building it

just match the size of the fan to the filter they start at 4in and go up from there.
edit] dont forget you will need ductin as well


but if you ever get some cash £100 get you every thing including fan/lead bracket carbon filter and ductin + shippin to ya house

you can buy a small filter for a bit more cash than building your own, but you can build a very large filter for way cheaper than buying one.

try a small ozone generator

The other word for this is negitive ion generator and you can build your own for $50 or less if you look real hard. Plus it takes care of several problems.

Kills mold
kills bacteria
kills odor
never have to change a filter
makes you feel good
will clean your whole house

all you need is a neon transformer piece of glass and a timer oops forgot the fan but it still can be done for less than $50. I can't believe they $500 - $700 for those things.
