It should be noted that the present study considered only two
kitchen range hoods in a single test house. Variations in the range
hood type, installation configuration, house geometry, and operating
conditions could alter UFP transport characteristics and influence
the range hood effectiveness. This study did not include cooking
food, although it did include boiling water. However, the findings
with respect to size-resolved effectiveness of the kitchen range
hood are not expected to be affected by the different size distributions
associated with cooking food.
