Honeywell HRF-U1
Score: 75/100
Appliancemates HPA300 Replacement Filter
Score: 82/100Rankings
The Appliancemates HPA300 HEPA Replacement Filter meets HEPA 13 and MERV 17 standards, offering 99.97% efficiency for particles 0.3 microns and larger. The inclusion of 6 carbon pre-filters helps extend the life of the main HEPA filters, providing good value for Honeywell HPA300 series owners. While it lacks specific certification data, it is a reliable choice for users seeking high-efficiency filtration.
The Honeywell HEPA-Type filter is a genuine replacement for HHT270/290 series purifiers, offering dual-layer filtration for allergens and odors. Its main drawback is the frequent four-month replacement cycle and lower particle capture efficiency compared to True HEPA. It is ideal for users of Honeywell tabletop/tower purifiers needing reliable, certified performance.
