HPA300 HEPA Filter Replacement Pack - 6 HEPA R + 8 Pre-cut

In this review of the HPA300 HEPA Filter Replacement Pack by APPLIANCEMATES, the bottom line is straightforward: this kit is built for households that need frequent, low-cost filter refreshes and expect strong particle capture without hassle. The kit includes six HEPA R replacement filters and eight pre-cut Type A carbon pre-filters sized for HPA300-series units, and it aims to restore the air purifier's ability to capture fine particles and odors. For anyone who wants a multi-year supply and fewer ordering cycles, this combo pack provides a clear convenience benefit.

Key Features

• Compatibility: Designed to fit Honeywell HPA300-series models including HPA300, HPA304, HPA3300, HPA5300, HPA5350 and HPA8350 so users should avoid cutting or trimming filters.
• Complete combo: Contains six HRF-R type R HEPA filters and eight HRF-A pre-cut Type A carbon pre-filters to cover routine yearly HEPA changes and quarterly pre-filter swaps.
• High filtration: The HEPA R filters are made from non-woven HEPA H13 / MERV 17 material intended to help maintain the unit's 99.97% particle capture performance for small particles.
• Pre-cut activated carbon: The A pre-filters are activated carbon and pre-cut to 14.2 x 17.3 x 0.2 in so they help reduce odors from cooking, pets, and smoke when replaced regularly.
• Durability and airflow: Constructed to reduce air resistance while preserving filtration efficiency, which helps the purifier maintain airflow and performance over time.
• Value pack sizing: The multi-pack format reduces the need for frequent purchases and keeps replacement parts on hand for routine maintenance cycles.

Who It's For

This kit suits families and pet owners who run HPA300-series air purifiers continuously and prefer stocking multiple filters to avoid frequent ordering. It is also a good match for kitchens or households with light smoke or odor concerns because the included Type A carbon pre-filters help manage smells between HEPA changes.

Shoppers who demand a guaranteed exact factory match for every model or who require single, OEM-labeled parts may want to compare fit carefully before buying, as some users report mixed fit results on particular units. If you only need a single replacement or prefer original-brand packaging, this bulk aftermarket set may not be the right choice.
