Dirty filters should be replaced to prevent equipment from working harder, resulting in energy waste and possibly causing damage to your unit. Filters should generally be replaced every month when the system is running. Filters should be replaced with the same kind and size as your original filter. If the filter is not disposable, follow the manufacturer’s instructions for cleaning it. The pre-filter and collection cells of an electronic air cleaner should be cleaned at least two or three times per year.
Check the filter every 3 to 4 weeks. Replace your filter when necessary, or clean it if you have the reusable type. Reusable filters, should be completely dry before they are re-installed.
