Specifications

Nominal filtration rating1 micron
Initial pressure drop at 20 gpm<1 psi

The nominal filtration rating is for a particle removal efficiency of 85%.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

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. The company, founded in 1966 and headquartered in Minneapolis, MN, meets International Organization for Standardization (ISO) standards 9001 and 14001 for quality assurance.

These are fantastic. I have been using these exact same filters since 2008. I replace one every year and at the same time I replace the same size post charcoal filter. I have it hooked up to my well water as a pre filter, as the water has a bit of sulfur and plenty of iron. I highly recommend

I installed a dual filter set-up at my house for municipal water filtration. I did not want a softener, as I don't like the added wasted water and the feeling in the shower.

This has helped remove the iron in the water, which was causing white surfaces to become tinged with red (toilets, showers, sinks, etc.) Not that the items were dirty, just the iron staining things.

Photos of the after affects and the filter set-up. It is 2 BB-20 filter housings with the pleated paper first then a charcoal filter to remove some other 'stuff' from the water.

Good filter with a caveat:

NOT for use on non-chlorinated water. Its not noted here, but it is on the packaging, that the cellulose doesn't get along well with some bacteria that is present in non-chlorinated water supplies, such as my well. I went ahead and tried it anyways.

It traps the sediment well, however, in my specific case, my water began to stink after a couple of weeks, and got to the point that I couldn't take it anymore. I changed to a staged non-cellulose filter, and my water no longer smells.

This filter is great for those who want to filter chlorinated city water. The pleated resin-impregnated cellulose and polyester fibers provides higher wet strength than regular cellulose cartridges. Because it is pleated, the filter provides 36 square feet of filtering surface area, which is quite amazing when you think it's housed in a 20"x4 1/2" housing. What makes this filter special is that it goes from 50 micron on the outside down to 1 micron on the inside.

This is a great pre-filter for the Pentek FloPlus-20BB Carbon Block Filter Cartridge, 20" x 4-5/8", 0.5 Micron.

The combination of the two filters is incredible. The filter is rated <1 psi @ 20 gpm (<0.1 bar @ 76 Lpm) Here is a link to the manufactures pdf on filter efficiency and performance: [...]

The filters "sediment reduction percentage efficiency" is 1 micron at 83% and 15 micron at 100%
