The Chamberland Pasteur Filter

GOLD MEDAL, HEALTH EXHIBITION, 1884

The Chamberland and Pasteur Filter is the joint production of the celebrated Professor Pasteur and his co-worker Dr. Chamberland, originally for the express purpose of eliminating disease germs and absolutely purifying waters used by them in Dr. Pasteur’s experiments.

The method of filtration is through specially prepared porcelain tubes used chiefly under pressure. No impurities enter the filtering tubes; it is, therefore, evident that they never can deliver impure water, nor do they need, as in carbon filters, any renewal of material. All that is required is that when coated with impurities these should from time to time be washed off with a sponge or brush. The tubes, from 1 to 100 in number in each casing (according to the quantity of water required), will in 24 hours deliver from 5 to 5,000 gallons of pure water. The prices are very low, especially taking into account that first cost is the-only outlay.
