Product Introduction
The True HEPA series is the cornerstone of effective air filtration. We utilize a specialized melt-blown polypropylene fiber matrix, electrostatically charged to act as a magnet for microscopic pollutants. Our production line uses automated pleating machines to ensure uniform spacing between folds, which is critical for maintaining consistent airflow and preventing "dead zones" within the filter. Each filter frame is constructed from reinforced heat-resistant materials and features a high-density EVA gasket to ensure a 100% airtight seal within the purifier housing. We strictly adhere to EN1822 standards, testing every batch for efficiency and resistance. Our HEPA filters are not just replacements; they are upgrades designed to restore your air purifier to its original factory-spec CADR rating, protecting both the health of the users and the integrity of the machine’s internal components.

Application Scenarios
Essential for all environments requiring high-purity air:
- Residential Homes: Protecting families from seasonal allergies, pet dander, and city smog.
- Medical Facilities: Capturing airborne bacteria and viral carriers in clinics and waiting rooms.
- Educational Institutions: Improving indoor air quality in classrooms to enhance student focus.
- Office Buildings: Reducing the spread of airborne illnesses in shared workspaces.
- Industrial Clean Rooms: Providing secondary filtration for sensitive electronics manufacturing.
- Q: How often should I replace my HEPA filter?
- A: We recommend every 6 to 12 months depending on local air quality and usage.
- Q: Can I wash a True HEPA filter?
- A: No, washing destroys the electrostatic charge and fiber structure. Always replace.
- Q: What is the difference between HEPA and HEPA-type?
- A: "True HEPA" must meet the 99.97% efficiency standard; "HEPA-type" is often much lower.
- Q: Do you offer custom sizes?
- A: Yes, we can manufacture filters to any custom dimensions for OEM projects.
- Q: Is it PFOA-free?
- A: Yes, our melt-blown media is 100% synthetic and toxin-free.
- Q: How do I know if the filter is full?
- A: A visible color change to dark grey or a noticeable drop in airflow indicates it is time to change.
- Q: Does it remove odors?
- A: HEPA captures particles; for odors, you need our "Activated Carbon" series.
- Q: Is there a discount for bulk orders?
- A: Yes, we offer tiered pricing for distributors and maintenance companies.
