24x20x4 AAF Flanders PerfectPleat MERV 8 Standard-Capacity HVAC Filter (6 Filters)

Description

This 24″ × 20″ × 4″ listing (part number 179-480-859) of the AAF Flanders PerfectPleat pleated air filter delivers MERV 8 filtration in the Standard Capacity configuration and ships as a case of 6 filters.

What Standard Capacity means

The SC (Standard Capacity) configuration is the everyday workhorse of the PerfectPleat line: MERV 8 filtration with lower initial resistance than the High Capacity variant. For most homes and light commercial spaces, SC balances filter cost, airflow, and dust-holding capacity.

MERV 8 — standard efficiency

MERV 8 is the baseline for good residential and light commercial filtration: effective against household dust, lint, larger pollens, and dust-mite debris — with low pressure drop so it protects airflow and coil performance. It’s the right choice when system protection and clean returns are the goal, not allergen-level filtration.

Design and construction

• Media: Self-supporting synthetic pleated media with a distinctive pleating pattern that maintains airflow and maximizes dust-holding capacity
• Frame: Moisture-resistant beverage-board with internal wire-mesh media support.
• Max operating temperature: 180°F (82°C)

Where it fits

Commercial and residential HVAC where a durable, reliable MERV 8 pleated filter is specified. Common in office buildings, schools, light commercial, and residential systems.

Replacement schedule

At 4″ depth, plan to replace this filter every 6–12 months 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.
