Source Custom Bio-Cone Air Filters

I want to add a new replacement set for home- and office-grade air purifiers to my existing filter catalogue. The reference unit—link supplied once the project starts—uses a distinctive bio cone pre-filter followed by additional media layers, so the supplier you locate must be able to reproduce that configuration or provide an equivalent private-label option. Here is what I need from you: • Identify and vet at least three manufacturers or trading companies that already make, or can custom-make, the complete filter pack (bio cone plus companion filters). • Collect full quotations showing unit price at different MOQs, tooling costs (if any), sample fees, lead-times, shipping options (FOB, CIF), and available branding/packaging services. • Verify any stated certifications (ISO, CE, RoHS, etc.) and request current test reports for HEPA efficiency and VOC/odor reduction. • Arrange physical samples sent to me; include photos or short video so I can confirm build quality before shipment. • Deliver a concise comparison report with your recommendation and all direct contact details for each supplier. Experience in Asian supply chains, and the ability to negotiate on my behalf are strong pluses.
