Overview

Meet the Aerostar 14x20x1 MERV 11 pleated air filters, offered in a convenient 6-pack. These filters use electrostatically charged synthetic media designed to capture a broad range of airborne particles while preserving airflow. The result is a simple, cost‑effective step toward a cleaner home environment without the need for complex changes to your routine.

What makes these filters stand out

• MERV 11 efficiency is comparable with MPR 1000–1200 and FPR 7, balancing filtration and airflow.
• Designed to trap microscopic particles such as lint, dust mites, spores, pollen, pet dander, fine dust, and smoke.
• Low air resistance combined with high filtration performance helps maintain steady airflow and comfort.
• Included as a 6-pack for steady supply and cost‑effective maintenance.
• Manufactured by Filtration Group, a leader in filtration solutions, with a focus on reliability and safety.

Fit, size, and installation

The nominal size is 14x20x1, with the actual size measuring 13 3/4" x 19 3/4" x 3/4" to ensure compatibility with many HVAC units. The design supports simple, tool-free installation and quick maintenance checks.

Performance and maintenance

• 100% synthetic electrostatic media delivers high efficiency while keeping resistance gentle on your system.
• General replacement cadence is every 60–90 days; during peak summer and winter, consider 30‑day changes for optimal performance.
• Regular replacement helps reduce dirt accumulation, potentially supporting smoother HVAC operation and less maintenance effort over time.

Real-life use and benefits

In homes with pets, cooking odors, or high pollen counts, these filters offer a practical way to keep circulating air feeling cleaner and surfaces looking less dusty. While not a medical claim, improved filtration can contribute to a more comfortable living space and a drop in visible dust on surfaces.

Care tips

Store extras in a cool, dry place and mark calendar reminders for regular changes. If your system runs hotter or more often in extreme weather, consider shortening the replacement interval.
