The Watts Pleated 20'' Cyst Filter Cartridge (Watts FM-BB-20-1A) is a 20"L x 4 1/2"D pleated water filter replacement cartridge used primarily in whole house water filter systems to reduce cysts (99% of Cryptosporidium and Girdia) though it will also reduce other contaminants such as sediment, dirt, turbidity, limescale, rust, sand, silt, and other common particulates down to the 1 micron level.
This Watts Flo-Max pleated water filter uses advanced synthetic pleated polyester filtration technology for a larger filter surface area, longer cartridge life, higher flow rate, greater dirt holding capacity, lower pressure drop, and more efficient cyst and sediment filtration when compared to other filters which use different types of filter media such as resin, melt blown, spun, string wound, etc. The 100% synthetic cellulose-free pleated polyester media does not contain binders or additives. Because it is a Full Flow filter with a large diameter (4.5"), the Watts FMBB201A features higher flow rates than standard diameter (2.5") filters.

Jessie - Indiana (Thursday, February 13, 2014)
I live in rural Indiana with extremely hard water and clear iron. I bougt this filter to replace the original sediment filter that came with my whole house filtration system. I've had my system only about 4 months and I am starting to see iron and hard water build up on my appliances, showers, toilets and washing maching. The original sediment filter was a 20 micron filter. I decided with the money I was saving buying from filtersfast.com, I'd spend a little extra and upgrade to this 1 micron filter. Since I am living on a well I am assming the cyst filtration qualities of this filter will be a benefit. A quick unscientific way to check for clear iron in your water is to put some bleach in a glass of water and it will immediately begin turning a rust color. (this is why ppl with well water tend to have dingy looking whites and it gets worse if they use bleach to 'fix' the problem) I've had this filter installed for 24 hours, I done a few loads of laundry, loads of dishes and the whole family has showered so I feel the water we are using is definitely water filtered by this new filter. I took a glass with water and poured bleach into it and even after letting it sit for hours, there is NO signs of any reddish color from clear iron. I am shocked!! And I am so so so thankful I took a chance on buying this filter. I'm not sure if this filter will make it an entire 6 mos before needing replaced but I'm so glad I have this filter. I am once again in love with my whole home filtration system.
