Maximize system performance by replacing your filter at the start of summer and the start of winter.

Breathing Easier.

Dust in the home? Pet dander? Ask your Westinghouse expert about a high-efficiency air filter or electronic air cleaner. They work at least seven times better than a standard filter at removing dust and other particles, and may need to be replaced just once a year.

If you have a standard furnace filter, you should check it monthly to make sure it's not blocking airflow. At a minimum, your filter should be changed twice a year.
