Are central air filtration systems necessary with heat pumps? Are central air filtration systems necessary with heat pumps?

Air filtration systems are added to many traditional heating and cooling installations in a home to clean the air of dust and other allergens. Dust tends to collect in duct work of these systems and thus creates problems in the home. A heat pump system contains its own air filtration system that uses replaceable or washable filters. Installing an additional central air filtration system would be redundant and a waste of money and energy to operate it. In areas of high dust or extremely dirty air, you can just clean the heat pump filters more often to maintain them.
