Cost-Saving Design

The smaller footprint of the VariCel M-Pak filter means that less space is required for storage. VariCel M-Pak filters weigh approximately 4 kg, less than half the weight of 292 mm deep filters with metal cell sides. This means reduced maintenance costs and time savings, as the VariCel M-Pak filter is easier to handle. Additionally, as a result of its reduced depth, the VariCel M-Pak filter is packed two to a carton, lowering freight costs and reducing the amount of space required for storage. The VariCel M-Pak filter also halves disposal volume and reduces disposal costs. Best of all, there is no performance penalty accompanying these savings. The VariCel M-Pak filter meets, or exceeds, the performance of the 292 mm deep filters it replaces.


The header and cell sides of the VariCel M-Pak filter are constructed of high impact polystyrene. The design, which encloses a fixed media pack, creates a rugged filter that resists damage during shipping, handling and operation. All components of the VariCel M-Pak filter are fully incinerable.

Dual-Density Media

The VariCel M-Pak media pack is constructed with wet-laid fibreglass that is moisture-resistant. The VariCel M-Pak filter can withstand exposure to free moisture in the atmosphere, making it ideal for installation in applications where moisture is an issue. The media is manufactured with two layers of glass fibres, coarser fibres on the air-entering side and finer fibres on the air-leaving side. The media pack is bonded to the cell sides using urethane sealant.

Our dual-density design allows dirt particles to be collected throughout the entire depth of the media pack, utilising the full filtering potential of the media and maximising dust holding. Maximising dust holding capacity extends the life of the filter and minimises operating costs.

Thermoplastic separators maintain uniform spacing between pleats to allow optimal air flow into and through the filter. The separators also ensure a large effective media area to minimise pressure drop and eliminate the need for aluminium separators. Without aluminium separators, risk of damage to the media pack from turbulent or non-laminar airflow is reduced.

Designed to Improve Indoor Air Quality

VariCel M-Pak filters with antimicrobial (Ultra treatment) are designed specifically to improve Indoor Air Quality (IAQ). Air filters are designed to trap and concentrate particulate air contaminants, including viable fungal and bacterial spores. The presence of antimicrobial in the filter media is intended to preserve the integrity of the media throughout the useful life of the filter. Antimicrobial preservatives are not meant to increase the efficiency of the filter, or to kill microorganisms “on the fly.”
