The September issue of Cleaning & Maintenance Management® magazine is now available online, featuring Bob Croft''s "Measuring And Improving The Air" article.
Croft states that one reason his company takes measurements during normal business hours is so that they''re measuring the same air their client is breathing.
He notes that after starting a building, they generally see an air quality improvement within two or three weeks in those buildings cleaned five times per week.
Croft adds that given the vastly differing buildings, various cleaning schedules and uncontrollable exterior conditions, indoor air quality (IAQ) varies markedly from building to building, even among those outwardly similar.
According to Croft, a quantifiably cleaner building sets a cleaning contractor apart from his competition and sets the building apart as well.
Bob Croft ( is president of CBN Building Maintenance, a 34-year-old janitorial service in Phoenix. He holds BSCAI''s CBSE designation and is quoted extensively in BSCAI''s "Guide to Green Cleaning." He''s a member of the Phoenix Environmental Quality Commission, the American Indoor Air Quality Council and arbitrates for the BBB. Follow Bob''s blog at
