14x18x1 Naturalaire Healthy Ultra MERV 13 Air Filter – Pack of 12

Description

This 14″ × 18″ × 1″ listing (part number 95003.011418) of the NaturalAire Healthy Ultra pleated air filter delivers MERV 13 filtration and ships as a case of 12 filters.

Individually sealed. Every NaturalAire filter ships individually wrapped inside the case — each filter protected from dust, moisture, and shipping damage until you’re ready to install it. A real quality difference from bulk-packed competitors, and it matters especially for customers reordering a case at a time.

What MERV 13 captures

Very fine particles including smoke, bacteria-sized particles, and virus carriers attached to larger droplets, on top of everything MERV 11 captures. Commonly specified for commercial spaces with higher indoor-air-quality requirements and for homes with wildfire smoke or air-quality concerns. Ensure your HVAC system is rated for the increased static pressure.

Design and construction

• Media: Multi-layer electret-free synthetic pleated media designed to capture fine particles including smoke and bacteria-sized particulates. Mechanical capture.
• Frame: Clay-coated moisture-resistant beverage-board with wire-mesh media support.
• Max operating temperature: 180°F (82°C)

Where it fits

Residential and commercial HVAC where MERV 13 is specified — including households responding to wildfire smoke, allergy/asthma concerns, or higher indoor-air-quality requirements. Confirm your HVAC system is rated for the increased static pressure.

Replacement schedule

At 1″ depth, plan to replace this filter every 60–90 days under typical residential or light commercial loading. High-dust environments, pet homes, wildfire smoke events, or construction-adjacent sites will shorten that window. Check the filter monthly through the first cycle to calibrate your schedule.
