FAQs on American Plumber water filter

Are American Plumber water filters compatible with standard filter housings?

Yes! American Plumber filter cartridges and Pentek cartridges fit in your standard 10” and 20” slim 2.5” housings, 10” and 20” BB 4.5” housings, and other sizes like 5” slim 2.5” housings. Each filter cartridge size is labeled clearly in the description.
What micron rating you should choose depends upon your filtration needs. For ultra-fine filtration with more filtration of contaminants, you may need a 5 micron or less filter. If maintaining water flow is more important, a 25 micron or higher filter may be a better choice.
All Filters does not offer a warranty on the American Plumber filters, but the manufacturer does offer a limited warranty on some of their products. SpiroPure compatible water filters, however, offer the same specifications and great filtration, with a 30-day guarantee.
Yes. These Pentek American Plumber replacement water filters can be used in any filter housing and system of the same size, no matter the brand. Just make sure to choose the filter cartridge dimensions that match your water filter housing.
It depends upon the type of American Plumber filter you choose. Carbon filters, for example, will adsorb chlorine taste and odors and reduce certain chemicals like pesticides and herbicides from water, while sediment filters reduce particulates like dirt, rust, and sand.
