Granular activated carbon ring panel filters for HVAC systems — particulate removal plus odor and gaseous pollutant control in a single drop-in filter.

OdorGuard Ring Panel Filter

Features & Benefits

OdorGuard Ring Panel Filters combine particulate removal with activated carbon odor control in a single drop-in HVAC filter. The outer polyester layer captures particulates like a conventional filter, while the CarbonWeb® core, packed with 60% activity granular activated carbon, adsorbs odors and gaseous pollutants. Self-sealing edges and standard ring panel dimensions make them interchangeable with most HVAC ring panel filters.

Three-stage filtration: polyester media, CarbonWeb® GAC core, and tertiary media to capture stray particulates or carbon
Granular carbon loadings of 45, 300, or 345 grams per square foot
Self-sealing edges for a secure non-bypass installation
Low air resistance disposable design with UL Class 2 approvals
Interchangeable with other ring panel and many standard HVAC filters
Available in 1 inch and 2 inch thicknesses, standard or custom sizes
