How much water does the average family use and how
long will a Kold Ster-il® last if used for whole house filtration?
Will there be sufficient water flow to the sinks
and bathroom fixtures?

The average family of four members consumes about 10,000 gallons per 90 day period. The Kold Ster-il® should last 45 days under the above conditions. Whole house filtration provides high quality water for drinking, baths, showers and laundry washing. Yes, toilets will also get high grade filtered water --- but, how do you separate the plumbing lines? The Kold Ster-il® can deliver 3.8 Gpm@40psig. Kitchen sinks, bathroom sinks and shower heads have flow restrictors which limit flow to 1gpm or slower. Other than starting the washing machine (on max. size load) and then trying to take a shower as the washing machine filled ---- a problem for most water softener customers ---- could prove difficult. If you are concerned about using filtered water in applications other than drinking? Install the Kold Ster-il® System on the cold water line under the kitchen sink. A large Kold Ster-il® will supply an entire house filtered water supply (150,000 gallons) for $0.0021 per gallon filtration cost.
