If you have never thought about it you should.  Your drinking water can be contaminated in many ways.  World Cup has done water filtration for a lotta years!  Our drivers monitor and change out your filters when necessary.  Many of our customers choose to have us change the filters on a regular quarterly or yearly basis.  There is a gallon rating on the filters but it depends on the quality of water flowing through.  If you are in an old building and rust is common then your filter will have a short life.  Call today if you are interested in water filtraion for your office.  Its cheaper than bottle water and we can connect it to your coffee brewer.
