Frequently Asked Questions About cardboard panel filter supplier
Q1: How do your cardboard frame air filters perform in high-humidity or moist operating environments?
A: As an experienced cardboard frame air filter manufacturer, we construct our disposable paper frame units using heavy-duty, moisture-resistant beverage board and water-repellent synthetic media. The frame maintains structural integrity and dimensional stability without softening, warping, or collapsing even in elevated humidity conditions.
Q2: What efficiency grades, sizing, and custom specifications can you supply?
A: We offer cardboard frame air filters across various efficiency ratings, including MERV 8 to MERV 13 (ISO Coarse to ePM10/ePM2.5, G4 to F8). As a trusted custom cardboard panel filter supplier, we manufacture standard nominal sizes (1″, 2″, and 4″ depths) as well as tailored frame dimensions, pleat counts, and media specifications to match your exact equipment requirements.
Q3: How do you protect the filters from damage during long-distance shipping and ocean freight?
A: Operating a modern cardboard frame filter factory, all our disposable pleated panel filters are shrink-wrapped and packaged in reinforced heavy-duty corrugated Master Cartons with edge protectors. For full-container export orders, goods are palletized and film-wrapped to ensure zero frame deformation or moisture exposure during transit.
Q4: What is your minimum order quantity (MOQ) and standard production lead time for bulk orders?
A: As a dedicated disposable pleated panel filter manufacturer, our standard MOQ for custom-sized beverage board frame filters is 500 units, while standard sizes carry a lower threshold. Average production lead time is 10 to 15 business days after order confirmation, supported by our flexible production scheduling for urgent high-volume projects.
Q5: Are your cardboard frame filters compliant with international testing standards and eco-friendly requirements?
A: Yes. Partnering with a reliable china cardboard air filter factory guarantees compliance with ISO 16890 and EN 779 filtration standards, as well as DIN 53438 flame-retardant classifications. Additionally, our recyclable paper board primary filters align with strict environmental standards, lowering disposal costs and supporting eco-friendly procurement programs.
