Air Duct Screen and Carbon Filter 8 inch Atomic Innovations

Made in USA. This fiber screen + carbon filter fits perfectly into 8 inch diameter air ducts. It will prevent small objects and particles from entering your duct system. Carbon filter layer has a MERV 4+ rating and will also reduce some odors. Polymer frame is weather resistant. Works well with greenhouses, small shops, and other light duty filtering applications where small objects, particles, and odors are a nuisance. Easily secured at intake with duct tape or hose clamp (not included). Not intended for use with hazardous gases. Max Temperature 180 F. Product works best in duct systems located near the fan/blower. Lengthy duct systems can produce decreased air flow where the filter may not perform well. Product may not allow sufficient airflow if used in conjunction with very low powered fans/blowers.
