| VeriFit Irritant Smoke Generators First all-in-one Irritant Smoke Generator for Respirator Fit Testing The VeriFit Irritant Smoke Generator revolutionizes respirator fit testing. Its patented plastic design integrates all traditional fit testing kit components into one convenient device. The small bellows size provides the optimum amount of smoke for fit testing yet minimizes the risk of overexposure. Unlike other test methods, there is no need for chamber construction, nebulizers, electric pumps, mixing jars, batteries, special test masks, mask probes, or testing hoods. There are also no parts to calibrate, warm up, sterilize, or clean. The VeriFit Irritant Smoke Generator comes ready to use. Everything you need for immediate qualitative fit testing is in one sleek, safe, and convenient smoke generator. Simulates Real Working Conditions - Reduces Health Risk |

| Irritant smoke is the only OSHA-accepted qualitative fit testing method that relies on the test subject’s involuntary response. It does not rely upon test subject’s sense of smell or taste. Qualitative fit tests such as banana oil (isoamyl acetate), saccharin, or Bitrex may cause false negative results. A common cause of false negative results is the failure of a test subject to identify a leak in the respirator. Many factors cause test subjects to not notice a leak: • Olfactory fatigue (reduction in ability to smell) • Gustatory fatigue (reduction in ability to taste) • Allergy or common cold • Ingestion of food or drink • Reduced sense of smell or taste due to aging, smoking, or other causes Field-proven as an OSHA-accepted respirator fit testing method since 1982.
