Limited Coverage: Typically have a limited range and may not effectively clean the air in larger rooms or multiple rooms without being moved around frequently.

Effectiveness: Their effectiveness can vary depending on factors such as room size, air quality, and the type of pollutants present. They may not always eliminate all contaminants from the air.

Limited Long-Term Cost Savings: While air purifiers can improve indoor air quality, they may not necessarily lead to significant long-term cost savings, especially if they require frequent filter replacements or consume substantial amounts of energy.

Aesthetic Disruption: Some portable air purifiers may clash with the existing decor or aesthetics of a room, especially if they have a bulky or industrial design.

Comprehensive Coverage: HVAC-integrated systems purify air throughout the entire space, unlike portable units limited to specific areas.

Space Efficiency: Integrated systems save space by being installed within existing ductwork, avoiding the need for multiple portable units.

Continuous Operation: Integrated systems run seamlessly with the HVAC, operating 24/7 without manual intervention, unlike portable units.

Aesthetically Pleasing: Integrated systems are hidden within the HVAC, maintaining the space's aesthetic appeal, unlike portable units.

Enhanced Filtration: Integrated systems accommodate larger and specialized

Low Maintenance: Integrated systems require less frequent maintenance due to longer-lasting filters compared to portable units.

Health Benefits: Integrated systems provide consistent indoor air quality improvements throughout the space, offering greater health benefits compared to localized purification from portable units.
