Maytag Microfiltration Wash System
®
No Filter Cup, No Chopper
The industry's first microfiltration system is a clear departure
from traditional, passive filtration because it continuously
filters 100% of the water, reducing the cycle time and energy
consumption on the heaviest loads.
Similar on the Surface, Radically Different Inside
The only visible filtration component of the new filtration system
is the coarse filter in the bottom of the tub. The rest of the high-
performance filtration system is below the tub.
How Microfiltration Works
1. Water and food particles flow through the coarse filter into
the filter housing.

2. An impeller pulls wash and rinse water into the spinning
ultra-fine filter.
3. The ultra-fine filter is cleaned by an area of back-pressure
created by two sets of wing-shaped blades located inside and
outside the filter.
4. Food particles remain suspended inside the filter housing;
filtered water is pumped back to the wash arms.
5. During draining, a secondary pump flushes out food particles
and soils.
