HEPA Box Air Filters
Control dust and contaminants in hospitals, laboratories, and other demanding environments. These filters have a rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems. The sealing gasket is on the downstream side of the filter.
The trade size is the actual size of the filter.
UL Classified-rated filters meet flame retardance requirements.

ULPA Box Air Filters
Purify the air in your most sensitive environments. These filters remove 99.999% of dust and other particles, so they're best in areas where high air purity matters, such as semiconductor, pharmaceutical, and aerospace facilities. Constructed with fibers more densely woven than a HEPA filter, they catch 10 times more particles. However, they need to be changed more often than HEPA filters because they collect contaminants more quickly. All are UL rated for flame retardance.

HEPA Long-Life Box Air Filters
Extend the time between filter changes in laboratories, hospitals, and other places with a high risk of airborne contaminants. These filters have tight pleats, which increase the surface area for catching particles. They’re a HEPA filter, so they capture small particles, such as allergens and germs, more efficiently than standard air filters.
Filters with an aluminum frame have a V-shape design that increases the filtering area and reduces resistance to air, leading to an even longer life than filters with a standard design.

Bench-Top Air Cleaner Hoods
Filtering away dust and particles, these hoods create a clean space for demanding work, such as bioprocessing, pharmaceuticals, electronics, and optics. They have a HEPA H14 filter to catch 99.995% of particles down to 0.1 microns, as well as a pre-filter to pull out large particles before they reach the HEPA filter. To draw air from outside the hood into the filters, they have a fan; there’s no need to connect them to ductwork. A flow monitor tracks the airflow and alerts you with a visible and audible alarm if the fan fails. They meet Fed. Std. Class 100 and ISO Class 5 clean room requirements.
As an alternative to filtering the air of an entire room, these hoods leave a large enough opening for comfortable access inside and have internal fluorescent lighting to help you see your work. Their work surface is 304L stainless steel, which resists bacteria and chemicals, and also is easy to clean. Mount them on workbenches and carts that are designed to hold them, or place them on your own bench top.

3D Printer Portable Air Cleaners
Draw particles and filament fumes away from open-frame 3D printers without cooling off printed parts. Unlike standard air cleaners, which create airflow strong enough to cool the print area and warp your parts, these low-airflow cleaners won’t disrupt your print. A three-part filtering process keeps you from breathing harmful emissions: a prefilter traps large particles, then a combination HEPA and activated carbon filter captures both fine particles and fumes. These CE marked cleaners meet health, safety, and environmental protection standards for products.
Attach the included hose and funnel to the cleaner to pull fumes directly from your printer. These compact, lightweight cleaners fit into most work areas, and are quiet enough for office use. The powder-coated steel housing holds up over a long service life.
