Before you buy
- Use HRF-G1 for the listed Type G relationship; Type H is not approved as a substitute.
- Honeywell multi-pack suffix is a quantity; it does not approve another purifier generation.
- These manufacturer-listed model codes cover US specifications. Another regional variant needs its own check.
- The Amazon action is a reference search; no exact retail product, seller or pack has been approved.
Find the complete model code
- Read the complete Honeywell model on the purifier label and retain every letter, digit and suffix.
- Match the label with one of the manufacturer-listed US codes on this page.
- Compare HRF-G1, components and quantity on the final merchant listing; the search does not approve the listed item or pack.
Filter and fitting details
- The product page explicitly lists the six model series retained here; each exact code also appears in the linked manufacturer model lookup.
- One purifier requires one or two G panels depending on its model. HRF-G1 is one panel, not a complete replacement for every tower.
- Panels per purifier: HPA020, HPA075 and HPA080 use one Type G panel; HPA030, HPA175 and HPA180 use two. Check the quantity before ordering HRF-G1.
- All six models require a separate Type A or A+ pre-filter. The G-panel product box does not include that component.
