A pitcher or carafe housing is provided that has a raw water reservoir. A high performance filter receives raw water from a lower portion of the reservoir. The water is preferably received at or travels through a water entry tube to the back and bottom of the filter. In about 1-3 minutes the water percolates through the filter element, until it reaches a water exit port. A pouring chamber may be provided at the side of the pitcher for receiving the water from the water exit port, so that the water will continue to be treated and flow up into the pouring chamber until the water level equalizes in height in the reservoir and the pouring chamber. The filter and its housing may be placed into and removed from the inside of the raw water reservoir, or the filer housing may be side loaded. The filter media may be a polyester non-woven mat with a weight of 4-7 oz./yd. impregnated with carbon or zeolite and subject to compression between about 25-75% (e.g. about 50%).

Static filter pitcher

A simple yet effective method and apparatus produce a web suitable for treatment of water as a static filtration media, e.g. to remove chlorine and lead from water in contact with the media. A web is coated with a coating composition that facilitates treatment of water and includes a binder, and the web is compressed in one dimension about 25-75% (e.g. 40-60%) so as to make the void size distribution substantially more uniform. The compression is substantially maintained until the binder substantially cures so that the coated final web produced has a second void size distribution more uniform than the first void size distribution, e.g. the coated final web having void volumes with a mean value of about 6-7&times;10 liters and/or an RDV/BV ratio of at least 0.4, and a porosity of greater than 90%. Compression may be at least primarily practiced by substantially immediately after coating passing the web through a series of staggered rollers; or by tightly winding the web prior to cure of the binder; or by compressing the web while in a curing tunnel using upper and lower compression belt roller assemblies. Coating may be practiced using a non-woven web having a weight of about 4-7 ounces/sq. ft., and by applying a coating equal to about 100-200% of the uncoated weight of the fabric comprising about 10-20% binder, about 60-90% activated carbon, and about 0-25% zeolite.
