The Aaron Smoke Shark is designed to be easy to use and extremely effective at smoke and particle removal at the operative sight. While designed for use with all electrosurgical generators, it is also excellent for use in controlling laser smoke. The Smoke Shark's 18-hour filter combines four-stage filtration in one casing (Pre-filter, ULPA, Carbon, Post-filter), keeping cost per procedure down and minimizing waste. The four-stage filter captures particles down to 0.01 √Ç¬µm with 99.99995% efficiency giving you the confidence you need for a safe work environment. The 24 ounces of carbon contained in the Smoke Shark filter, over twenty times the amount of a competing brand, does a superior job in odor elimination.
