CocoCarbon Pre-Filter for Sierra Series LP250TH/LP250THP, 2 Pack

Natural coconut carbon based pre-filter captures larger particles before they reach the HEPA filter, extending the life of the HEPA filter. The activated carbon filter also reduces harmful VOCs (volatile organic compounds) and household odors such as cooking and pet odors. CocoCarbon filter material is made from naturally and sustainably sourced coconuts. Recommended to replace pre-filter every three (3) months for maximum efficiency.
