Where can I buy replacement filters for the HPA090, and what are the correct part numbers?

Replacement filters can be ordered at www.replacementfilters.com or by calling Kaz Consumer Services at 1-800-477-0457. The correct replacement filters are the True HEPA filter R model HRF-R1 (single pack), HRF-R2 (2 pack), or HRF-R3 (3 pack), and the Odor Reducing Pre-Filter model A HRF-AP1 or the Household Gas & Odor Reducing Pre-Filter model A HRF-APP1. The HPA090 series uses 1 HEPA R replacement filter. (Page 4)
