Did you know? Honolulu’s windward side (Kailua, Kaneohe) receives over 60 inches of rain annually while the leeward side gets only 17 inches. Mold risk varies dramatically depending on which side of the island you live on. For more guidance, EPA provides expert resources on mold testing guidelines.
