Score: 75/100
Sgizoku Honeywell Filter
Score: 78/100Rankings

The Sgizoku Air Purifier Filters are a cost-effective third-party alternative to OEM Honeywell filters, offering True HEPA filtration and activated carbon pre-filters. While they effectively capture 99.97% of particles at 0.3 microns, they lack independent lab verification for their performance claims. Best suited for owners of Honeywell tower purifiers dealing with dust, pollen, and pet dander who want a budget-friendly maintenance solution.

The Funmit HPA300 is a budget-friendly, third-party HEPA filter replacement designed for Honeywell HPA300 series air purifiers. It offers standard filtration efficiency but lacks the activated carbon and pre-filters included in some OEM bundles. It is best suited for users seeking affordable bulk replacements for large-room purifiers.
