What Is an HAF (High Air Flow) Filter?
HAF filters use an electrostatic charge and a unique open-channel microstructure to trap particles while allowing air to pass through with minimal resistance. This is critical for LGR (Low Grain Refrigerant) dehumidifiers that require high-volume airflow to operate efficiently — blocking that airflow directly reduces drying performance.
| Media Type | Electrostatic charged microstructured synthetic media |
|---|---|
| Airflow Rating | High CFM — maintains performance throughout loading cycle |
| Microbial Resistance | Anti-mold surface treatment applied |
| Frame Material | Cardboard or rigid plastic (customizable) |
| Washing | Do NOT wash — destroys electrostatic charge |
| MOQ | Flexible — contact us for your quantity |
| Sample Lead Time | 7–10 business days |
| Certifications | ISO 9001:2015, ISO 14001 |
Open Channel Design
Provides a larger surface area for particle capture without the rapid pressure drop seen in standard pleated filters — keeping CFM high from day one to replacement day.
Electrostatic Capture
The media is permanently charged to pull dust, allergens, and mold spores from the airstream like a magnet — no mechanical density required.
Resists Mold/Mildew
Includes an antimicrobial surface treatment to prevent the growth of odor-causing microbes on the filter — essential in water-damaged environments.
Consistent Performance
Unlike mechanical filters that degrade as they load, HAF filters maintain their rated airflow throughout their service life — predictable drying performance every job.

HAF Filter Buying Guide for Restoration Professionals
Choosing the right HAF filter for your fleet comes down to three factors. Here is what procurement managers and equipment distributors need to know.
1. Fit & Compatibility First
HAF filters are model-specific: the frame dimensions, media thickness, and tab configuration must match your equipment. Nantong Deli manufactures to exact OEM specifications for the Dri-Eaz LGR 700, LGR 2800i, LGR 3500i, Phoenix 200 MAX, Dri-Pod series, and other professional restoration dehumidifiers. Send us your machine model and we will confirm fit before sampling — or provide frame dimensions if you need a custom size not yet in our catalog.
2. Electrostatic Efficiency vs. MERV Rating
Standard HAF filters rely on permanent electrostatic charge to capture particles — no added pressure drop, maximum CFM throughput. For jobs involving elevated particulate (demolition debris, mold remediation), we also offer MERV-rated HAF media variants that provide higher particle capture efficiency while maintaining acceptable airflow. Discuss your typical job-site conditions with our technical team to choose the right media grade for your application.
3. Fleet Volume & Supply Continuity
Restoration companies running 10–200+ machines need reliable, predictable supply. Nantong Deli ships HAF filters to North American and European distributors with standard lead times of 15–30 days for production runs. We offer blanket PO arrangements and safety-stock programs for high-volume accounts. Contact us to discuss a supply agreement that keeps your fleet operational without inventory gaps.
