D The toxins are collected in a water reservoir, which is drained monthly for cleaning. Question 3 Why are biofilters seen as alternatives to mechanical air handlers? A By filtering indoor air, biofilters save on heating and cooling costs. B Biofilters heat the air naturally using plants' respiratory properties. The plants on the biofilter filter smoggy air from outside, which uses less energy Question 4 Where are the VOCs? A In indoor air B In outdoor air In the microbes on the plant roots Question 5 How many mesh panels are there? A Two B It depends on plant diversity The number is variable
