While some air filters can be cleaned and reused, it’s generally not recommended for filters used in refrigeration systems. Cleaning filters can damage the media, reduce their effectiveness, and even introduce contaminants into the system. Disposable filters, such as fiberglass filters, should be replaced regularly to ensure optimal system performance and safety. For reusable filters, such as pleated filters, follow the manufacturer’s cleaning and maintenance instructions to ensure their effectiveness and longevity.
