Import Air Filter — Buy in Bulk from Supplier in China

This pleated panel air filter is manufactured by Huahong Yongsheng Auto Parts Co., Ltd. in Dongcheng District, Dongguan, Guangdong Province, China. The unit employs multi-layer filtration technology with a graded fibre media pack designed to capture particulates across the respirable range. The source description indicates high airflow capacity with minimal resistance, though no tested pressure drop or initial resistance value in Pascals is stated. The filter frame is described as durable for HVAC duty, but exact frame material, whether cardboard, galvanised steel, or plastic, is not specified in the listing data.

The media pack typically consists of progressively structured synthetic fibres or glass microfibre, with optional pre-filtration layers for coarse dust loading in industrial environments. Standard HVAC panel filters in this category commonly achieve ISO coarse or ePM10 classification under ISO 16890, though the supplier does not cite a tested grade. The pleat count, media area, and seal method are not provided; buyers should request these to calculate dust holding capacity and expected service life. The source mentions ISO and CE compliance, but no certificate numbers or testing laboratory accreditation are given, so verification is needed.

Primary applications include commercial HVAC systems, residential air handling units, and light industrial ventilation where general ventilation filtration is required. The supplier notes healthcare and manufacturing end uses, but buyers in critical care or cleanroom environments should confirm whether the product meets EN 779 or HEPA-grade standards before specification. Trade terms stated include FOB and CIF options with L/C and T/T payment methods, though exact lead times, MOQ, and packaging configuration are absent from the data and must be confirmed directly with Huahong Yongsheng.

Huahong Yongsheng Auto Parts Co., Ltd. is located at Dongcheng District, Dongguan, Guangdong Province, China, postal code 523000. The supplier is classified under the imported tier with a harbor trust designation. The response rate is recorded at 0.00 percent with zero average response hours, indicating that the supplier has not responded to platform inquiries during the tracked period.

The listing presents the company as a manufacturer of air filters for residential and industrial segments, but the source description contains broad marketing language with limited verifiable operational detail. No named clients, export markets, or specific production capacity figures are disclosed. Buyers should conduct direct due diligence, including factory audit or video verification, given the absence of response signals. The address places the supplier within the Pearl River Delta manufacturing cluster, a region with dense automotive and electronics supply chains.
