HEPA 13 vs HEPA 14 Air Sentry Replacement Filters
Keep your air continuously fresh by stocking up on Air Sentry Replacement Filters. Both options offer excellent filtration — here's how to choose.
HEPA 13
The True HEPA 13 filter captures 99.97% of particles 0.3 microns or larger. This includes dust, pet dander, pollen, and smoke. Because of the slightly larger filter size, air can circulate faster — making it a great choice for everyday use, especially during spring and summer months when dust and pollen are more common.
HEPA 14
The True HEPA 14 filter captures 99.997% of particles 0.1 microns or larger — offering even finer filtration. This smaller micron rating means it can catch smaller particles that pass through a HEPA 13. Many customers prefer the HEPA 14 during fall and winter months when they want that extra level of filtration.
Triple Filtration Technology
Unlike traditional air purifiers that rely on a single filter, the UltraLux Air Sentry line combines three filtration stages:
- Activated Carbon Filter — helps reduce common household odors and VOCs
- True HEPA 13 Filter — captures 99.97% of particles 0.3 microns or larger
- UV-C Light Component — included as part of the internal filtration chamber design
This multi-stage system is designed to help your home feel fresher, cleaner, and more comfortable.
With Air Sentry products, you can capture and reduce:
- VOCs
- PM2.5 particles
- Dust
- Pet dander
- Pollen
- Smoke
- Household odors
All Air Sentry units come with a True HEPA 13 filter, plus a free True HEPA 14 filter so you can choose the level of filtration that works best for your needs throughout the year.
Keep your filters stocked and your air feeling fresh!
