STAINLESS STEEL BAFFLE FILTERS
About Your New Filters
Stainless Steel Baffle Filters do not need linings or mesh inside of the filters and are
completely constructed out of stainless steel. The stainless steel construction allows
them to be used again after being cleaned or going through the dishwasher.
How do Baffle Filters Work?
They function by forcing the grease filled air to quickly and continuously change direction
as it passes through the filter. The grease is unable to change direction as fast as the air
carrying them, they end up getting caught on the metal blades and then trapped into the
filter tray.These filters are both efficient and require less maintenance.
