Then agents were sent out to the houses to show the filters and offer them for rent at 10 cents each a month, a fresh filter to be installed every month. The agents were given one-half of all the money they collected, and as nine in every ten households gave them contracts, both agents and originator of the plan realized a steady and handsome income.
At the end of the month the agent would call at each house, take off the old filter, attach the other end to the faucet, set a clean glass under it, turn on the water and show the lady a glass filled with impurities. That would settle it. She would at once hand over another 10 cents for a fresh filter, and the agent would proceed to the next house.
Between 5,000 and 6,000 filters were thus kept rented, the old ones refilled with fresh material, and the man who used this plan and a little money not only saved hundreds of lives, but cleared up over $13,000 for himself in three years’ time.
