상품 특징

• [EXACT SIZE & HIGH YIELD] Maximize your value with our oversized air filter roll. Stop buying expensive precut sizes! Use household scissors to custom-cut perfectly for any odd-shaped vents. The 12" x 90" roll yields 25+ standard (4"x10") or 35+ small filters.
• [MERV 8 EQUIVALENT FILTRATION] Safely captures up to 85% of airborne particles down to 3.0 microns. The 100% electrostatic polyester media effectively traps household dust, lint, seasonal pollen, and pet dander, creating a significantly cleaner breathing environment for allergy sufferers and pet owners.
• [ZERO AIRFLOW RESTRICTION] Protect your expensive HVAC motor. Our 0.5-inch thick filter features an ultra-low initial resistance (~0.10 in. w.g.) and a massive 350g dust-holding capacity. It purifies the air entering your room while maintaining safe, balanced, and unrestricted airflow.
• [5 HEAVY-DUTY HOOK STRIPS] Includes 5 extra-long adhesive hook strips. CRITICAL INSTALLATION TIP: 90% of adhesive failures occur due to invisible floor wax or dust. Vigorously wipe your vent grille with rubbing alcohol and let it air-dry completely before applying the tape for a permanent, no-peel hold.
• [MULTI-VENT COMPATIBILITY] The ultimate cut to fit air filter solution for your entire ductwork system. Highly effective for floor registers (stops dirt and dropped toys), ceiling grilles (prevents black dust rings), return wall vents, mobile home furnaces, and RV camper AC units.
• [DIRECTIONAL DUAL-LAYER DESIGN] Engineered with progressive density for a longer lifespan. For proper installation, ensure the WHITE side faces the duct (to catch large incoming debris) and the BLUE side faces the room (to trap fine micro-particles).
• [MAINTENANCE STRICT WARNING] Replace the filter every 60-90 days (or every 30 days for homes with heavy-shedding pets). DO NOT WASH THIS FILTER. Water permanently destroys the electrostatic charge required to capture microscopic dust. Always replace with a fresh cut.
