Multi-Pleat XL8 Mechanical MERV 8 Extended Surface Pleated Panel Filters
The Koch Multi-Pleat XL8 is a medium efficiency extended surface pleated panel filter, engineered to provide higher initial efficiencies and overall superior performance than standard pleated filters.
Multi-Pleat XL8 Variations
- The Multi-Pleat XL8 carries a MERV 8 and MERV 8-A performance rating in accordance with ASHRAE Test Standard 52.2-2012.
- The MERV 8 and MERV 8-A performance rating provided by the Multi-Pleat XL8 make the filter an excellent upgrade from disposable filters and standard MERV 6 and 7 rated pleated filters.
The Multi-Pleat XL8 is the best selection in applications such as hospitals, laboratories, pharmaceutical plants, commercial office buildings, and in any system in which a higher degree of indoor air quality is required.
Multi-Pleat XL8 Construction
- The Multi-Pleat XL8 media is produced with an optimal blend of highly specialized fibers, developed by Koch Filter Corporation specifically for use in extended surface air filters.
- Developed to deliver a “one of a kind” performance, this specialized media operates on mechanical filtration principles which provide high efficiency, low pressure drop and high dust holding capacity.
- The Koch Multi-Pleat XL8 maintains a MERV 8 performance rating before and after conditioning steps when tested in accordance to ASHRAE Test Standard 52.2-2012.
Multi-Pleat XL8 Construction
Two Media Area Capacity Levels:
The Multi-Pleat XL8 is an extremely versatile line of pleated panel filters which can be used in a wide variety of filtration systems worldwide.
In order to meet the different requirements found in these applications, Koch offers the XL8 Series in two media area capacity levels.
Multi-Pleat XL8
Standard Capacity XL8 filters provide a combination of efficiency, economy, and excellent overall performance.
Standard Capacity XL8 filters are an excellent choice in applications where filter change schedules are based on preventive maintenance schedules.
Multi-Pleat XL8-HC
High Capacity - 30% more media.
High Capacity XL8-HC filters are similar in construction to the Standard Capacity but have the added advantage of approximately 30% more media.
The additional media results in extended filter life, making the XL8-HC the ideal filter for use in filtration systems where filter change schedules are predicated on recommended final pressure drop readings.

Koch 102700003 – Frequently Asked Questions
1) Will the Koch Multi-Pleat XL8 fit my 20x25x1 return grille?
Yes, 20x25x1 is one of the nominal sizes the Multi-Pleat XL8 standard capacity pleated filter is made in. The 1 inch depth range also covers 14x20, 14x24, 14x25, 16x20, 16x25, 20x20, 20x24 and 24x24. Nominal is the call-out size, so a filter labeled 20x25x1 is what drops into an opening marked 20x25x1.
2) What depths does the Koch Multi-Pleat XL8 pleated filter come in?
Orderable depths on the XL8 standard capacity run 1 inch, 2 inch and 4 inch, across sizes from 12x20x2 up to 25x25x2 and 24x24x4. The XL8 line as a whole is built in 1, 2, 4 and 6 inch depths. Depth is set by your filter track, not by preference, so measure the rack before you pick: a 2 inch filter will not seat in a 1 inch slot and a 1 inch filter in a 2 inch track will bypass air around the edges.
3) Do these Koch filters lose efficiency as they load, like electrostatic filters do?
No. The XL8 uses mechanical MERV 8 media that is not reliant on electrostatic charge for efficiency, and Koch states it holds its MERV 8 rating both before and after the conditioning steps of ASHRAE 52.2-2012. That conditioning step is the part of the test that strips electrostatic charge, which is why a charged filter can test MERV 8 out of the box and perform lower in service. The XL8 also carries a MERV 8-A rating, the A designation being the post-conditioning result.
4) Should I buy the standard capacity XL8 or the XL8-HC high capacity?
It comes down to how you schedule changeouts. The standard capacity XL8 is the choice when filters get swapped on a fixed preventive maintenance calendar, quarterly, semiannual, whatever your route is. The XL8-HC carries roughly 30 percent more media, which extends filter life, and Koch calls it the one to use where changes are driven by a final pressure drop reading rather than a date. Both are the same MERV 8 construction.
5) Is MERV 8 enough of an upgrade over the MERV 6 pleats I'm buying now?
It is a step up, and Koch positions the Multi-Pleat XL8 exactly that way: an upgrade from disposable and standard MERV 6 and 7 rated pleated filters. The MERV 8 rating is per ASHRAE Test Standard 52.2-2012. For a property manager running a mixed fleet of RTUs, that is the usual move when tenants complain about dust without going to a filter your equipment cannot pull air through.
6) Will a pleated MERV 8 filter restrict airflow in a residential furnace?
The XL8 is rated for commercial, industrial and residential HVAC, and the media is built for low resistance to airflow with high dust holding capacity. Practical note for a house or a small package unit: depth matters more than rating. A 1 inch XL8 in a 1 inch slot is a straight swap for the fiberglass or standard pleat that is in there now. If the equipment has a 2 or 4 inch rack, use the deeper size, since more media area over the same face means less resistance at the same airflow.
7) Will these Koch filters hold up in a humid mechanical room or a rooftop unit?
The frame is a moisture resistant beverage board with a double wall design, so damp return air will not collapse the frame the way plain chipboard can. That double wall construction is also what keeps the pleat pack from racking in the track under high face velocity.
8) Is MERV 8 the right filter for a hospital or lab air handler?
Koch names hospitals, laboratories, pharmaceutical plants and commercial office buildings as applications for the Multi-Pleat XL8, and any system where a higher degree of indoor air quality is required. In those buildings a MERV 8 pleat is normally the prefilter stage protecting a higher efficiency final filter downstream, and the mechanical media matters there because the rating does not decay with charge loss.
9) Can I standardize a whole building on one Koch XL8 size?
Only if the openings actually match, and in most buildings they do not. The XL8 standard capacity covers 32 nominal sizes, so the practical approach is to walk the units, list every size, and order against that list. The common commercial faces are all here: 16x20, 16x25, 20x20, 20x25 and 24x24 in both 1 and 2 inch, plus 20x24 and 24x24 in 4 inch. Odd faces like 12x20x2, 18x20x2, 20x30x2 and 25x25x2 are covered too, which is usually where a mixed fleet trips up.
10) What is the difference between an extended surface pleated panel filter and a flat panel filter?
Pleating is what buys you media area. A flat fiberglass panel presents only its face area to the airstream, so it loads fast and filters little. The XL8 pleats the media so a 20x25 face holds far more square footage of media than 20x25, which is what gives it high dust holding capacity and low resistance at the same time. That is the whole reason a pleat lasts longer than a throwaway panel in the same track.
