The PREMIERONE cph-1000 is a pre-filter replacement kit designed for use with the HP500 HEPA air purifier. The kit includes both a paper pre-filter and a carbon media pad filter, working together to capture airborne particulates and reduce odors before air reaches the primary HEPA stage. This combination extends the life of the main HEPA filter by trapping larger particles upstream. The kit is a direct OEM-style replacement intended for installation by HVAC technicians or experienced IAQ service professionals maintaining whole-home or commercial air purification equipment.
This replacement kit is suited for residential and light commercial air purification systems where scheduled filter maintenance is required. The pre-filter and carbon filter both carry a rated service life of 6 months under normal operating conditions, making this a standard bi-annual replacement item. Compatible references include the GeneralAire 4610 used in the AC500 and 4600 series units, as well as the Captura CPH1000 HEPA system. Replacement is typically performed during routine HVAC maintenance visits.
Designed as a replacement kit for the HP500 HEPA air purifier. Compatible with GeneralAire 4610 for AC500 and 4600 series units, and the Captura CPH1000 HEPA system.
A licensed HVAC technician or qualified IAQ service professional should perform filter replacement. Power down the air purification unit at the disconnect or breaker before opening the filter access panel. Follow the manufacturer service manual for correct filter orientation and seating to maintain proper airflow direction through the filter stages. Dispose of used filters per local waste guidelines and note the replacement date to track the next 6-month service interval.
