Frequently Asked Questions
Find answers about filter selection, custom orders, maintenance and product documentation.
How do I choose the right air filter?
Start with your application, equipment dimensions and required filtration performance. Send us the existing filter label, photographs and available specifications for review.
Can you help identify an existing filter?
Send clear photographs of the filter, its label and installation, together with its width, height and depth. These details help us review possible options. Matching appearance or dimensions alone does not confirm equivalent performance.
What information should I provide for a quotation?
Please provide the filter type or model, dimensions, required specifications, quantity and delivery destination. Photographs or drawings are helpful if the model is unknown.
Can I request a custom size or construction?
Send your required dimensions, frame details, sealing arrangement and application. Available customization options depend on the product and will be reviewed before specifications are confirmed.
Can I request a sample?
Please contact us with the product and quantity you need. Sample availability, cost and delivery arrangements are confirmed for each request.
What are the minimum order quantity and lead time?
Minimum order quantity and lead time depend on the product, materials, customization and order quantity. These details will be confirmed in your quotation.
How often should filters be replaced?
Replacement timing depends on the filter, contaminant load, operating conditions and equipment requirements. Follow the specified pressure-drop limits and maintenance instructions rather than a single fixed interval.
Can the filters be washed and reused?
Only filters specifically identified as washable should be cleaned, using the approved method. Do not wash or reuse disposable filters. Contact us if you are unsure about your filter model.
Where can I find installation instructions?
Visit our Installation & Maintenance page for general guidance. Always follow the instructions supplied with your specific filter and equipment. Contact us if you need clarification.
Can I request a test report?
Please provide the product model or required specification. Available reports and testing scope vary by product. Reports apply only to the tested samples.
Do you have an ISO 9001 certificate?
Our ISO 9001 certificate is available on the Quality Control page. Please refer to the certificate for the stated organization, scope and validity information.
Can I specify inspection or documentation requirements?
Please share the required inspection items, acceptance criteria and documentation before ordering. Our team will review these requirements with you.
