question on filters
I have been wanting to make an evaporation cooler but I don't want to pay a hole bunch of money for distiled water to refill the system. So I was wondering where I could get a good priced filter? I looked at all of the filters at the local places and they all seem like they need a really powerful pump (12 gpm or higher) and they are super expensive like $50 or more.
Thanks for the help.
