| This study is to evaluate the ability of interior plants to produce anion and relative humidity
that can purify polluted indoor air. Four indigenous woody plants in Jeju islands such as
Sarcandra glaber (Thunb.) Nakai, Illicium anisatum L, Cleyera japonica Thunb. and Ilex
rotunda Thunb. were used. Sansevieria trifasciata cv. Laurentii was also used as a
comparative plant. The amount of anion and increment of relative humidity produced by five
species of indoor plants was assessed by anion measurement (ITC-201A)in a sealed acryl
chamber (118Ã118Ã119.5cm).
The highest amount of anion was 515 ea/cm3produced by I. rotunda. The amounts of
anion were 293 ea/cm3, 273 ea/cm3, and 211 ea/cm3 in S. glaber, I. anisatum and C.
japonica, respecively while it was 220 ea/cm3 in S. trifasciata. The increment of relative
humidity was highest in I. anisatum as 27.4% while it was lowest in S. trifasciata as 14.0%.
This result suggested that all four indigenous plants tested were more effective to purify the
indoor polluted air than S. trifasciata.
