Experience ultimate air purification with our complete 4-piece HEPA cabin air filter system for Model Y. Unlike standard 2-filter replacements, this comprehensive set includes both upper and lower layer filters for maximum filtration coverage—capturing 99.97% of airborne particles including PM2.5, pollen, bacteria, and harmful gases throughout your entire HVAC system for hospital-grade air quality.
Why Choose the Complete 4-Filter System?
Complete HVAC Coverage: Includes 2 upper filters + 2 lower filters for total air filtration system replacement—most competitors only offer 2 filters, leaving half your system unprotected.
Triple-Layer HEPA Filtration: Advanced multi-layer design combines melt-blown electrostatic layer, HEPA filter media, and activated carbon to capture particles as small as 0.3 microns in just 30 minutes.
Maximum Odor Elimination: Dual-layer activated carbon in both upper and lower filters provides superior odor absorption from traffic exhaust, smoke, and environmental pollutants.
Optimal Airflow Performance: Maximized filtration area maintains 98% ventilation rate across all four filters, ensuring powerful HVAC performance without restricting airflow.
Premium ABS Frame Construction: High-quality ABS plastic frames resist deformation and cracking, ensuring long-lasting performance and perfect fitment.
Perfect OEM Fit: Custom-engineered to exact specifications for seamless installation in all Model Y variants (2020-2026+) including Juniper.
Upper vs. Lower Filters - Why You Need Both:
Model Y features a dual-layer air filtration system. The upper filters provide primary filtration for incoming air, while the lower filters offer secondary filtration and recirculation protection. Replacing only one layer leaves your cabin vulnerable to pollutants—our complete 4-pack ensures total air quality protection.
When to Replace Your Filters:
Every 12-18 months or 10,000-15,000 miles for complete system refresh
Musty or unpleasant odors when running climate control
Reduced airflow from dashboard vents
Increased dust accumulation on interior surfaces
Frequent driving in polluted, dusty, or construction areas (replace more often)
Allergy season or passengers with respiratory sensitivities
