Williams 3501921 Filter

The unit filter was created for filtering tiny dust fragments and other miniscule particles as it passes through. This helps protect the unit and make it operate a lot better at doing its job while, at the same time, filtering the dust out of the air you breathe all day. Due to the amount of dust in the house, the filter should be replaced or cleaned periodically in order to keep things clean.

What warnings should I watch out for to know if my Williams air filter has a need to be replaced?
