Indoor air qualityIn my IAQ clausing articles I have long fussed and fumed over the need for companies claiming to be in this business to have testing capabilities. I came across Air Quality Sciences, which provides such services to hvac contractors. The company rents you the sampling equipment, tells you how to use it and provides accurate test results.UV light kills bacteria. Ozone kills mold and bacteria. mini drill press both have been used in iaq remediation systems for years, and several companies displayed such wares. however, i was struck by the way these concepts were put together in a well-thought-out package from sol aire. its whole house air purification system combines a germicidal lamp and an ozone press generator in a single device. you simply cut a hole in the plenum and insert the active elements. integral mounting magnets hold it in place. plug it into a standard 120v outlet. the system turns itself on and off automatically by sensing air flow. many new iaq test tools were on display, but the one with which i was the most impressed was tpi''s model 705 carbon monoxide analyzer. it reads co levels out directly in ppm. it''s fast and easy to use.

it was an exhibition of stupidity and hubris, but golf architects could help by routing cartpaths clausing where shots are likely to end up, and by installing yardage markers on the paths. we can help, too. when i hit my ball into drill a hopeless position far from any pavement, i don''t wander around like an amnesia victim. i leave the cart with my partner, sling my bag over my shoulder, and finish the hole on foot. in this technological age of computerized golf carts with global positioning systems that read yardages and keep score, several resorts have begun offering retro caddie services and courses for walkers only.
