The VeriFit Irritant Smoke Generator revolutionizes respirator fit testing. Its patented design integrates all traditional irritant smoke test components into one convenient device. Plastic construction eliminates danger from broken glass. Small, attached bellows provide the optimum amount of smoke yet minimize overexposure. Unlike other test methods, there is no need for nebulizers, pumps, mixing jars, batteries, test masks, probes, or hoods. There are no parts to calibrate, warm up, sterilize, or clean. Irritant smoke is the only OSHA-accepted qualitative fit testing method that does not rely on the test subject’s subjective response. Other types of qualitative fit tests, such as banana oil (Isoamyl acetate), saccharin, or Bitrex, may cause false negative results. Each VeriFit Irritant Smoke Generator is a complete, safe, ready-to-use, OSHA-compliant fit testing kit. Each box contains 10 fit test tubes.
