Watts®Pleated Cartridges
Greater surface area, longer l i fe,
reduced filtration costs!
Watts pleated cartridges outperform wound, spun, melt 
blown, resin bonded and other “depth” style filter elements 
because our pleated cartridges provide increased surface 
area, lower pressure drop and longer service life. Our 
100% synthetic media is washable and cleanable, five 
micron and up, to reduce filtration costs.

“Theirs”
Watts, cellulose-free, 100% synthetic filter media 
allows the pleats to retain their form, maintaining a 
large amount of surface area. This allows the cartridge to handle higher solids loading and flow rates 
with a lower pressure drop that increases the filter 
efficiency and life, while reducing filter change out 
costs and frequency.
The difference is the media!
VS.
The cellulose blended pleats collapsed on one 
another, blinding off large amounts of the 
cartridges surface area. Premature blinding of the 
surface area reduces the flow capacity and efficiency while raising the differential pressure, and 
contributing to shorter filter life and frequent filter 
change outs.
