Need Support? We’ve Got You Covered

Explore answers to frequently asked questions about our solutions for dust collection, HVAC air filtration, and solid-liquid separation—including materials, certifications, and custom options.

What filter bag materials are available? How to choose the right one?

FiltEdge offers common materials including Polyester, Acrylic, Aramid (Nomex), Fiberglass, P84, PPS, FMS, PTFE, Basalt, PE, PP, and Nylon. Customized materials are also available. Material selection depends on factors such as the filtration medium (acid/alkaline/oil), operating temperature, and filtration precision (micron rating). Our engineers are available to assist you with free technical consultation.

How is filtration accuracy (e.g., 1μm, 5μm) tested? Can you provide test reports?

The appropriate test method depends on the product and application. Available manufacturer test reports, test conditions and third-party inspection options are reviewed for the specific order. FiltEdge LLC does not claim its own testing laboratory.

Do you offer filter bags with special properties such as anti-static, flame-retardant, or antibacterial?

Yes, we support customization with features such as conductive fibers (anti-static), flame-retardant coatings, water/oil repellency, PTFE membrane, high-temperature resistance, and chemical resistance. Please provide your specific application requirements.

Do your products comply with EU/US market standards?

Compliance must be reviewed for the specific product, intended use and destination market. Available manufacturer documents are checked for their applicable model, scope and validity. No blanket CE, FDA or REACH claim applies to every FiltEdge product.

Can you provide complete compliance documents such as MSDS or COA?

Please list the documentation required for your product and intended use. Availability and scope of material documents, certificates of analysis and third-party reports must be confirmed before ordering.

Do you support OEM/ODM services? What is the minimum order quantity (MOQ)?

OEM/ODM options can include dimensions, materials, construction, packaging and logo printing. Minimum order quantity, sample availability, sample charges and timing are confirmed after reviewing the specifications.

What is your production lead time? Is expedited production available?

Production and delivery timing depend on specifications, quantity, material availability and the production schedule. The applicable lead time is confirmed in the quotation. Expedited production requires separate availability and cost confirmation.

Does your pricing include tax and shipping? Do you offer volume discounts?

The quotation specifies the trade term and whether taxes, freight and other charges are included. Volume pricing or alternative delivery terms can be discussed for the order.

What payment methods do you accept? Can you accept Letters of Credit (L/C)?

Payment methods, deposit requirements and balances are confirmed in the quotation and order agreement. Please discuss any letter-of-credit or alternative payment requirements before ordering.

Is your packaging moisture-proof and damage-resistant? Can you print customized shipping marks?

Our standard packaging includes dust-proof bags and reinforced cartons. Shipping marks (e.g., PO numbers, special labels) can be printed according to your specifications.

How do you handle quality issues?

Please provide the order details, photos and available inspection results so our team can review the issue with the manufacturer. Warranty scope, remedies and return arrangements are governed by the agreed order terms; no standard three-month warranty or automatic refund is promised.

Which industries are your filter bags used in?

Our filter bags are widely used in industries such as water treatment, food & beverage, chemical & petrochemical, pharmaceuticals & biotech, electronics & electroplating, metallurgy, mining, energy, automotive, textiles, and paper manufacturing.
