How does the Dacall 4-layer filtration work in everyday use?

The filter stacks targeted media to address different types of contaminants. A coconut-activated carbon layer reduces common odors and gases while a HEPA-style shield captures fine particulates; microfiber and a reinforced frame stop larger debris and keep the unit stable.

• Coconut carbon layer for odor and gas adsorption
• HEPA-style layer traps pollen and fine dust
• Microfiber mesh stops hair, leaves and larger particles
• Reinforced frame resists collapse in humid conditions

Will installing these filters affect HVAC performance and maintenance?

Replacing clogged or aged cabin filters helps restore proper airflow and reduces strain on ventilation components. Regular replacement supports steady cabin circulation and can help prevent musty smells caused by saturated media.

• Recommended replacement interval: about every 12 months or 12,000 miles, depending on conditions
• Replacing clogged filters can improve heater and A/C efficiency
• Helps reduce cabin odors and airborne particulates
• Extends life of HVAC system by preventing debris buildup
