Honeywell HPA300 Replacement Filter R

Honeywell's "Filter R" (HRF-R1) is the True HEPA replacement filter for the Honeywell HPA300 and HPA200 air purifiers — both share the same filter housing, so one filter fits either unit. It is not interchangeable with Honeywell's other filter families (Filter A, Filter Q, or Filter T) used in different Honeywell purifier lines — those use a different housing shape and won't seat correctly in an HPA300/HPA200. To confirm which filter your unit needs, check the model number on the back of the purifier — if it reads "HPA300" or "HPA200," Filter R is the correct replacement.
