I work with my son in a successful internet business selling products mostly
he invented and patented.  It is not MLM.  We sell Sweetfilters that install
on roof vents and septic tank vents that rid yards of sewer odors.  We also
sell Sweetfiler manhole covers that remove the odors from coming out of
drains in streets.  We also sell Sweetfilter manhole covers that keep the
waste water from causing the drains to overflow.  We also sell solar
aerators for ponds to stop fish kills in winter and summer. We also sell
portable airconditioners.  I only joined the other sites for free Knowledge
and advertisement, of course we do use Google and yahoo pay for clicks.
Thank you for your help and interest.
