Wholesale Filter & Dust Bag FAQsMOQ, Samples, OEM, Quality & Quotations
Use these answers to understand the current XINFILT product scope, customization options, evidence boundaries and the information needed for a useful first enquiry.

A FAQ answer is not a product certificate, compatibility guarantee, fixed MOQ, sample promise or binding quotation. Product-specific terms are confirmed in writing for the actual project.
PRODUCT & COMPATIBILITY
Product-scope questions
Start by identifying the real product and the evidence available for fit and construction.
Which products are included in the first XINFILT website?
The launch range covers air purifier replacement filters, vacuum cleaner dust bags and wet/dry vacuum filters. Other replacement parts can be discussed without assuming they already have a dedicated supply program.
Is XINFILT a consumer online store?
No. The website is designed for B2B enquiries from wholesalers, distributors, importers and private-label businesses. It does not provide consumer checkout.
Can I send a drawing, measured photos or a physical sample?
Yes. Those inputs are often more useful than a generic product name because they help define dimensions, construction, fit and the sample path.
Can XINFILT guarantee compatibility from a third-party model name alone?
No. Compatibility should be confirmed against approved dimensions, mounting, connector, sealing and application information, with a sample or housing review where appropriate.
CUSTOMIZATION & COMMERCIAL
OEM, packaging, MOQ and sample questions
Confirmed capabilities still require product-specific commercial review.
Do you support OEM and ODM projects?
Yes. OEM and ODM are confirmed capabilities. Feasibility, tooling, sample requirements and commercial terms depend on the actual product and project scope.
Can I request private-label or custom packaging?
Yes. Pack count, label, carton, insert and artwork requirements can be reviewed after the product basis is clear.
What is the minimum order quantity?
There is no single published MOQ for every product. MOQ depends on construction, materials, tooling, packaging and production setup.
Can I request a sample before a bulk order?
Sample feasibility, cost and timing are reviewed case by case after the product basis and required materials have been clarified.
QUALITY & QUOTATION
Evidence, timing and RFQ questions
Avoid unsupported claims by stating the documents and acceptance criteria your market requires.
How long is the lead time?
Lead time is quoted after the product, sample, quantity, packaging and production requirements are understood. The website does not publish one unsupported number for every item.
Are all filters HEPA rated?
No. Shape, pleats or a media name do not prove a complete filter rating. Any grade or efficiency statement requires an agreed construction and suitable evidence.
Can you provide certificates or test reports?
Available factory, material or product documents must be confirmed for the specific enquiry. The website does not claim documents that have not been supplied for the project.
What should I send for a quotation?
Send your name, company, business email, target market, product category, dimensions or sample information, intended use, estimated quantity and customization or packaging needs.
