Fine working , powerfull ozonizer. because it has no blower or casing ? it heats up in seconds. But in that time it produces enough ozon to sterilize the whole room . 7000mg/ H means 2 mg O3 per second. Mac value is 0.06 mg/ M3 . So every second about enough ozon is formed for 34 M3 of air. Average height is 2.6 meter so 13-14 m2 of size is treated per second. That’s why a minute timer is often to long time. A blower and a seconds programmable clock has to be used. Do not underestimate the power of these units. Ozone des integrated in about 30 minutes . when air is refreshed, these factors in combination of the refreshing rate tells you how often/ long (or really short) you have to use it. Measuring the ozone concentration is the best way. It is to be used to prevent infection , not cause lung damage itselve!! About product and delivery : Perfect 100% satisfied!
