  • FITS 10-INCH BIG BLUE HOUSINGS - Sized 10" x 4.5" to drop into any Big Blue or heavy duty whole house housing and replace most 10-inch sediment cartridges, handling high flow at under 5 psi at 10 gpm.

Description

Pentair Pentek WP-BB Series Cartridges are manufactured in 10" and 20" lengths and in 4.5" diameters from a durable polypropylene string that is wound around a rigid polypropylene core. The WP-BB Cartridges are an economical solution to reduce fine sediment including rust, sand and scale particles. The material in the WP-BB Cartridges is a fibrous polypropylene media wound in a precise pattern around a polypropylene core, providing greater surface area to maintain high flow rates. The WP-BB Cartridges are manufactured using an -static agent during the winding process to reduce the electrical charges produced during the winding process. These string-wound cartridges are capable of withstanding temperatures up to 165°F (73.9°C), and will accommodate flow rates between 10 and 65 GPM with minimal pressure drop. WP-BB Series Cartridges are suitable for a wide range of sediment applications including municipal and well water, and are chemical so they can be used with many industrial fluids. Note: The -static agent used in the WP-BB Cartridges may cause some foaming during start up of a new cartridge. If foaming

whats up now with California government's intrusion on a great filter
Style: 5 Micron
great product - as others said it is a 5 micron not 0.5 micron product but I want the 5 micron - any smaller and would clog in minutes - I am on a public water system that is in rural USA so national TV doesn't broadcast how our water is terrible - high in manganese, iron and other toxic chemicals. It's color has lots of black and brown nasty dirt! worse than flint Michigan water! But heck rural USA doesn't count! When you use blow off to clean the lines between mainline and house I use a white 5 gal bucket and you can't see the bottom. Not sure if the nasty particles make it to water tap but color is clear after using the filter!. Now here is the latest: these filters have little stickers on them that state of California requires I gather stating: "warning: cancer & reproductive harm"! now explain to me how a cotton string filter can cause cancer - actually if it stops all those nasty pollutants in my water it will prevent cancer not cause it - have to love California regulations. Didn't say why they thought it would cause cancer guess everything to them does. But why put these stickers on everyone's filter - I don't live in California. I am ignoring this notice - it is better than no filter and drinking heavy metals that are in the city water system! I will continue to buy these - great filters. I had the Pentek solid filter that went from 25 micron to 1 micron but water doesn't flow well thru them and if you have a lot of participants in your water they clog within a month - so USE this one a lot better and longer lasting and does take out the participants. ... show more

Great filter.
Style: 5 Micron
Like another reviewer noted, this is incorrectly described as .5 micron when it is actually 5 micron. This is good as I wanted the 5 micron and ordered the .5 micron by mistake last time. The model number is virtually the same except for the “.”. We have well water with high iron and manganese as well as some sediment. We use this as our whole house filter before other treatment equipment and an RO system. Over time we have tried various filter types including the blown poly and string filters like this one. This is one of the few 5 micron 10” string filters that is rated at 20 gpm. The string filters seem to work best for our water and seem to filter better and leave the water tasting better. With the blown poly we still get some bad tastes that the string filters seem to take out. The flow rate seems a bit better with this model filter so I think we will stick to this. ... show more
