Why Our Round HEPA Filter Stands Out?
1. Lightweight Paper Frame: Practical & Cost-Effective
- Snug, Secure Fit: Precision-cut circular edges ensure a tight seal with your equipment's intake, preventing unfiltered air from bypassing the filter.
- Easy to Install: Lightweight design makes swapping filters a 30s task without tools.
- Eco-Friendly & Safe: Made from moisture-resistant, recyclable paperboard , free of harmful chemicals.
- Durable Enough: Reinforced paper edges resist bending or tearing.
2. Melt-Blown Composite Media: The Filtration Workhorse
- Graded Density Structure: Coarser outer layers catch large particles , finer inner layers trap tiny contaminants-maximizing filtration without restricting airflow.
- Low Air Resistance: Even at H13 efficiency, initial resistance stays ≤120Pa (at 200m³/h).
- High Dust-Holding Capacity: Holds up to 300g/m² of particles (varies by efficiency), extending replacement cycles.
- Lint-Free & Stable: Won't shed fibers into your air or degrade over time.

Frequently Asked Questions (FAQ)
Q: What's the advantage of round filters over rectangular ones?
A: Round filters provide 360-degree air intake, reduce airflow resistance, and are ideal for cylindrical purification systems where space optimization is crucial.
Q: Are paper frames durable enough?
A: Yes, our reinforced paper frames are specially treated for strength and moisture resistance, maintaining shape throughout the filter's lifespan.
Q: Can you help with technical specifications?
A: Yes, our engineering team provides full technical support for product selection and application guidance.
