🌿 H13 True HEPA Filter – Advanced 3-Layer Filtration for Healthier Air
This model features a H13 True HEPA Filter, one of the highest filtration standards available for home air purifiers. It captures 99.97% of airborne particles as small as 0.1 microns, including dust, pollen, smoke, mold spores, and pet dander.
What makes the Pulluty FLT4825 stand out is its activated carbon pre-filter, which absorbs household odors, cooking fumes, and volatile organic compounds (VOCs). This combination ensures your air stays fresh and safe to breathe—perfect for allergy sufferers or pet owners.
The multi-layer filtration system works in three stages:
- Pre-Filter Layer – Captures large particles like hair and lint.
- Activated Carbon Layer – Neutralizes odors and traps harmful gases.
- HEPA 13 Layer – Traps fine dust, allergens, and microscopic pollutants.
Together, they create a powerful air purification system that rivals the original Germ Guardian filters in both efficiency and longevity.
💰 Excellent Value 4-Pack – Long-Term Savings
Each package includes 4 HEPA filters, offering outstanding value for money. Instead of buying individual filters every few months, this bulk set ensures you’re covered for the entire year (and beyond).
- HEPA Filter Dimensions: 15.7″ (H) x 4.5″ (L) x 1.3″ (W)
- Carbon Filter Dimensions: 15.7″ (H) x 4.5″ (L) x 0.2″ (W)
For optimal performance:
- Replace HEPA filters every 6–8 months

🐾 Activated Carbon Pre-Filter: Your First Line of Defense Against Odors
The carbon pre-filter in this replacement set does more than just protect the HEPA layer—it’s your home’s odor control system. It absorbs:
- Pet smells and hair
- Smoke and cooking odors
- Harmful VOCs and airborne chemicals
It also prevents these particles from reaching the HEPA layer, which extends the lifespan of the filter and keeps your air purifier running smoothly.
