Frequently asked questions
Common questions about MICROSHIELD from 3G Electric.
What is a MICROSHIELD zero-bypass minipleat air filter?
A MICROSHIELD zero-bypass minipleat air filter is a filter that uses closely spaced pleats of synthetic media in a frame designed to minimize air bypass around the media. The zero-bypass construction forces air through the filter media rather than allowing it to leak between the media pack and the frame. These filters are rated MERV 15 and are available with plastic or chip board frames, with or without a single header. They are used in commercial and industrial HVAC systems for fine particulate filtration.
What MERV rating do MICROSHIELD minipleat filters have?
The MICROSHIELD zero-bypass minipleat air filters listed by 3G Electric are rated MERV 15. MERV 15 filters capture a high percentage of particles in the 0.3 to 10 micrometer range, including fine dust, smoke, and other airborne particulates. This rating makes them suitable for applications requiring higher efficiency than standard MERV 8 or MERV 13 pleated filters. The MERV 15 rating is consistent across the SKUs supplied, including both plastic-framed and chip board-framed versions.
What sizes are available for MICROSHIELD zero-bypass minipleat air filters?
MICROSHIELD zero-bypass minipleat air filters are available in several nominal face sizes and depths. The sizes supplied by 3G Electric include 12 in x 24 in x 2 in, 16 in x 20 in x 4 in, 20 in x 20 in x 4 in, 20 in x 25 in x 4 in, 24 in x 24 in x 2 in, and 24 in x 24 in x 4 in. Depth options are 2 in and 4 in. Frame material and header configuration vary by SKU. When selecting a replacement, confirm the existing filter's nominal dimensions, depth, frame type, and header requirement.
What is the difference between a single-header and no-header MICROSHIELD minipleat filter?
A single-header MICROSHIELD minipleat filter has a header frame on one face, which provides a sealing surface and can help with installation in certain filter housings. A no-header filter does not have this extra frame, so it relies on the filter's own frame for sealing. The choice depends on the filter rack or housing design. For example, SKU 809KP4 (MP4H15P-2424) is a single-header model, while SKU 809KN6 (MP415P-2424) is a no-header model. Both are MERV 15 and use synthetic media.
What frame materials are used in MICROSHIELD minipleat air filters?
MICROSHIELD zero-bypass minipleat air filters are available with plastic frames or chip board frames. Plastic frames provide a rigid, moisture-resistant structure, while chip board frames are a common option for dry HVAC applications. The media material is synthetic in all listed SKUs. Examples include SKU 809KP4 with a plastic frame and single header, and SKU 809KM8 with a chip board frame and no header. The frame material should be selected based on the operating environment and the filter housing.
Where are MICROSHIELD minipleat air filters used?
MICROSHIELD zero-bypass minipleat air filters are used in commercial and industrial HVAC systems for high-efficiency particulate filtration. Typical applications include office buildings, manufacturing facilities, hospitals, and other spaces where fine airborne particles must be controlled. The MERV 15 rating makes them suitable for protecting downstream equipment and maintaining indoor air quality. They can be used as final filters or as prefilters in multi-stage filtration systems, depending on the overall design and target efficiency.
