12x25x1 Koch XL8 MERV 8 Pleated Air Filter – 12-Filter Set

Description

This 12″ × 25″ × 1″ listing (part number 102-041-003) of the Koch Multi-Pleat XL8 pleated air filter delivers MERV 8 filtration in the Standard Capacity configuration and ships as a case of 12 filters.

What Standard Capacity means

The SC (Standard Capacity) configuration is the everyday workhorse of the Multi-Pleat XL8 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: 100% synthetic blended fibers, engineered for high initial efficiency and low pressure drop. Mechanical capture — performance doesn’t fade.
• Frame: Recyclable beverage-board frame with double-wall construction for high-humidity durability. Expanded galvanized-steel grid bonded to the air-exiting side maintains pleat uniformity.
• Max operating temperature: 200°F (93°C) continuous

Where it fits

Commercial office buildings, schools, retail, light industrial, and residential HVAC where extended-surface pleated filtration is specified. UL 900 and ULC-S111-07 certified.

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.
