Cooking is one of the most significant activities affecting air quality in any home

Cooking creates a significant amount of humidity and airborne particles and even with mechanical rangehoods the effect is not typically dealt with adequately. The resulting poor air quality becomes a major factor in the occupant's likelihood of developing illnesses such as asthma and allergies.

High level, operable windows in kitchen spaces deal with this polluted air well, by allowing it to escape quickly without creating uncomfortable drafts in cold weather conditions.

Indoor air quality can be measured easily with a range of tools now available on the market.
