Yes, an air purifier can potentially contribute to prolonging the life of your HVAC system. By capturing airborne particles like dust, pollen, and pet dander, air purifiers help prevent the accumulation of contaminants in the HVAC system. This reduces strain on components like filters and coils, improving overall efficiency. While not a substitute for regular HVAC maintenance, air purifiers can be a valuable addition to your indoor air quality strategy, indirectly supporting the longevity of your HVAC system.
