PF Filters

BlockAide™ Electrostatic Filter Media

BlockAide™ electrostatic filter media, used for our extensive selection of Pulmonary Function Filters, consists of a special blend of polymers with highly stable electrostatic charge on each individual fiber, which allows the filter to consistently achieve high efficiencies by using both electrostatic and mechanical impaction to remove airborne bacteria and viral particles.

Exceeds ATS recommendations for “Standardization of Spirometry Equipment” for in-line filters having a flow resistance of less than 1.5 cm H2O/L/sec.
