Honeywell pack quantity and purifier capacity are separate facts. HRF-R3 is a box of three Type R panels, but HPA100 uses one panel, HPA200 uses two and HPA300 uses three.
Type G has the same issue in reverse: HRF-G1 is one panel, while some documented towers need two. Several of these systems also require a separate pre-filter that is not included with the HEPA panel.
HEPA panels needed per purifier
The pack reference does not change the number of panels installed in the purifier.
| Purifier models | HEPA requirement | Other component |
|---|---|---|
| HPA094 / HPA100 / HPA104 | 1 Type R panel | 1 separate Type A or A+ pre-filter. |
| HPA200 / HPA204 | 2 Type R panels | 1 separate Type A or A+ pre-filter. |
| HPA300 / HPA304 | 3 Type R panels | 1 separate Type A or A+ pre-filter. |
| HPA020 / HPA075 / HPA080 | 1 Type G panel | 1 separate Type A or A+ pre-filter. |
| HPA030 / HPA175 / HPA180 | 2 Type G panels | 1 separate Type A or A+ pre-filter. |
| HPA830 / HPA830W | 1 Type J HRFJ830 | Separate HRF-AP1 or HRF-APP1 pre-filter. |
| HPA6000B / HPA6000W | 1 integrated Type F HRFF6000 | Three layers are integrated in the replacement. |
Translate the box into complete changes
An HRF-R3 three-pack supplies three complete HEPA changes for a one-panel HPA100, one complete HEPA change for a three-panel HPA300, or one two-panel change plus one spare panel for an HPA200. The separate pre-filter is still needed in each case.
Do not apply that arithmetic to Type F. HRFF6000 is documented as one integrated three-in-one filter rather than a box of separate HEPA panels.
