20" x 2.5" Pleated Sediment Filter, 0.45 Micron
High-efficiency pleated polypropylene filter with DOE end caps for demanding whole-house and RO pre-filtration applications
The Watts FPP-0.45-20-DOE delivers fine sediment removal with significantly greater surface area than wound or spun alternatives. Engineered with 100% polypropylene synthetic media, this 20-inch pleated cartridge handles high flow rates while maintaining low pressure drop across temperatures from 40°F to 175°F.

Designed for Flow-Max Filter Housings
This cartridge is engineered specifically for Watts Flow-Max filter housings that accept 20-inch cartridges with DOE end caps. The 0.45 micron rating makes it ideal for high-purity water applications, reverse osmosis pre-filtration, and food/beverage processing where fine sediment removal is required. The pleated construction offers increased dirt-holding capacity and longer service life compared to traditional depth filters, reducing maintenance frequency and operating costs in whole-house and commercial installations.
