Is AirDoctor HVAC Home filter an alternative to portable Air Purifier?

No, while the HVAC filter provides powerful purification for your entire home, it does not provide the same protection and efficiency as AirDoctor portable purifiers. Additionally, the HVAC filter helps protect your HVAC system by capturing large particles such as dust that could damage it. HVAC systems and its filters only clean the air when it is in use and circulating the air.
