Smilyan HPA300 HEPA Filter Replacement Kit for Honeywell HPA300 Series — 6 H13 HEPA-R + 8 Activated Carbon Pre-Filters

Smilyan HPA300 HEPA Filter Replacement is a full replacement kit—six H13 True HEPA R filters plus eight activated carbon pre-filters—designed to fit Honeywell HPA300-series air purifiers.

Keep your Honeywell HPA100/200/300 and related models running efficiently with a ready-to-install pack of Smilyan replacement filters. This set pairs high-efficiency H13-grade HEPA-R elements with activated carbon pre-filters to capture microscopic particles and reduce common airborne odors. The bundle supplies multiple filter cycles in one purchase, so you avoid frequent reordering and get predictable fit and performance without having to measure or modify parts.

Which Honeywell models will these Smilyan filters work with?

These Smilyan filters are manufactured to match the fit and airflow profile of several Honeywell units so replacement is simple and tool-free. They are made for R-type HEPA replacements and the A-type activated carbon pre-filters commonly used in Honeywell HPA-series purifiers.

• Compatible with Honeywell HPA090, HPA100, HPA200, HPA250, HPA300 and HPA5000-series models
• Replaces Honeywell HRF-R3, HRF-R2 and HRF-R1 HEPA cartridges
• Activated carbon pre-filters sized for HRF-A300 (A-type) installations
• Designed to drop in without trimming or adapters

How do Smilyan filters capture particles and control odors?

Smilyan combines a true H13-grade HEPA media with a high-absorption activated-carbon pre-filter to address both particulates and volatile compounds. The layered construction reduces pressure on the fan while maintaining strong particle capture, and the carbon layer adsorbs many odors and gaseous impurities.

• H13 True HEPA media captures extremely small particles to high efficiency
• Activated carbon layer adsorbs smoke, cooking smells, and volatile compounds
• Electrostatic electret treatment enhances particle attraction for longer life
• Lower-density construction keeps energy draw and airflow resistance down

What comes in the package and what are the dimensions?

The kit is sold as a value bundle that includes multiple replacements so you can swap filters on schedule without extra orders. Smilyan lists clear dimensions so you can confirm fit before you buy.

• Includes six HEPA-R replacement filters and eight activated carbon pre-filters
• HEPA-R filter dimensions approximately 10.2" H × 6.5" L × 1.6" W
• Activated carbon pre-filter dimensions approximately 17.2" H × 14.2" L × 0.2" W
• Packaging arranged for easy storage and straightforward installation

How reliable and durable are these replacement filters?

Smilyan uses non-woven fabric, activated carbon, and an electrostatic electret treatment to balance filtration efficiency with longevity. The design aims to reduce fan load compared with denser media while still delivering sustained capture performance across use cycles.

• Constructed from high-quality non-woven fiber and activated carbon media
• Electret-treated HEPA for improved particle attraction and energy savings
• FSC-certified paper and materials where applicable for responsible sourcing
• Multiple replacements in one pack minimize downtime and repeat shipping

Who is this for: This Smilyan replacement filter kit is for owners of Honeywell HPA-series purifiers who prefer a ready-made, value-packed supply of genuine-fit filters. It suits households that want predictable maintenance intervals, small-particle filtration with H13-grade media, and extra activated carbon for odor control. Choose this kit if you want straightforward compatibility, multiple spare filters at once, and components engineered to balance filtration performance with energy efficiency.
