This Pentek P-250A under-sink filter set is suitable as a replacement filter set for use with the Pentek US-1000 under-sink chemical and lead filtration system (not included). It reduces the presence of 43 different volatile organic chemicals (VOCs), lead, cysts, mercury, asbestos, methyl tertiary butyl ether (MTBE), and chlorine taste and odor, and has a lifespan of 1,000 gallons. The system meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) Standard 42 for the reduction of chlorine taste and odor and Particulate Class I, and Standard 53 for the reduction of asbestos, cysts, lead, mercury, turbidity, MTBE, and VOCs. This under-sink filter set is suitable for residential and commercial drinking water filtration.

Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.

Pentair manufactures industrial, commercial, and residential water filtration components and systems under the Pentek brand. The company, founded in 1966 and headquartered in Schaffhausen, Switzerland, meets International Organization for Standardization (ISO) standards 9001 and 14001 for quality assurance.

Fresh look at all

A great item that I used to filter the water for my cooking, coffee, and soups. Have been using them for a few years and with the first use, I could tell the difference how my coffee and food tasted. Very effective at removing the things that make drinks and food taste funny.

Great filter!

A guy came to the house trying to sell me a water system. He had all this stuff to test my water and he pulled water from a bottled water I had in the pantry, our sink, and our filter system. When he tested the samples to show me how I needed to buy his system, the water that came from our current filter didn’t have chlorine or any of the other stuff he was testing for! Even the bottled water from the store had chlorine and that shocked me but not the water from this filter! Great filter!

Excellent solution for two cartridge water filter systems.

Best value I have found on Amazon as well as other sites for filters for a two cartridge system. They fit properly in the 10′ standard cartridge system and our water tastes pretty good, almost as if there was a polishing filter in line. Best combination of price and length of service I have found. Having said that, I suggest that “length of service” stated on these filters is only a comparison! Your water filtration needs as well as usage my demand you change these more often.

High end filters at a reasonable price.

I purchased these filters because they are used in a CR top-rated undersink system, the American Plumber WLCS-1000. Two high quality filters for $25 is a good deal. I checked the single Omni filter CR rated and it was $40+.

This kit fits my under-sink GE Smartwater filtration system. I buy the Pentek P-250A because it is the best price I can find for this type of product. The filtration seems to be top-notch based on good water taste, of course I haven’t run any water analyses to really test performance! Luckily my municipality water is not known to have contaminant issues, so filtering for flavor is my main concern anyway.
