The PUR AIR® COMBO filter fits easily in place of any standard 2''-thick throw-away particulate prefilter. As air passes through the PUR AIR® COMBO, dust is removed in the particulate section and odorous gases are controlled in the activated carbon section. The PUR AIR® COMBO is most effective in a recirculating application. Each time the recirculated air passes through the filter, its level of purity is increased.
Odor and Dust Control Filter
The PUR AIR® COMBO provides a quick, inexpensive solution to most odor problems. The filter removes odors from smoking, cooking, light manufacturing, restrooms, and many other applications.
The Pur Air® Combo is Well Suited For Use In:
- Office building
- Health club
- Shopping mall
- Beauty salon
- Doctor and dentist office
Particulate Filter Media
The particulate filter is produced from reinforced, nonwoven cotton fibers. The media has a high dust retention capacity due to the unique formation of the fibers, which offers maximum surface area. For safety purposes, the media is treated with a fire-retardant additive, UL Class 2 for Flammability. This media is rated at 25%-35% average efficiency when tested in accordance with ASHRAE test method 52-2-2007. The air resistance value exceeds 90%. The filter has a high reliability under all operating conditions.
PUR AIR® COMBO filters are enclosed in a aluminized steel frame. This unit includes diagonal support members, which are an integral part of the frame. Each member, and all inside surfaces, is bonded to the particulate media pack and the carbon pack. This bonding ensures proper pleat spacing, retention of pleat and carbon pack, and eliminates the possibility of contaminated air bypassing the filter. When assembled, the two mating sections of the frame overlap to provide a rigid double wall construction on all four sides.
The carbon pack is fabricated of a rigid support structure charged with activated carbon. The activated carbon typically has a surface area of 1,000 square meters per gram or over one million square feet of surface area per square foot of PUR AIR® COMBO filter. The activated carbon is loaded in the carbon pack in a partial bypass configuration to promote odor removal and long life in a recirculation application. The actual life of the filter is a function of the dust loading and vapor loading of each application.
Continental Carbon Group is constantly striving to improve its products and capabilities and to provide the best product to it customers.
Continental Carbon Group may from time to time develop product improvements or alterations (including, without limitation,

Making Air Safer and Cleaner
Wet activated carbon removes oxygen from air, causing a severe hazard to workers inside carbon vessels. Confined space/low
oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable local,
state and federal guidelines.
