Import Air Filter — Buy in Bulk from Supplier in China

Sincerehope Industry Co., Ltd supplies a HEPA air filter with separator standard capacity construction, manufactured in China for industrial and commercial HVAC systems. The filter employs a multi-layer media pack with aluminium or kraft paper separators to maintain pleat spacing and maximise particulate holding capacity. The source indicates capture of allergens, dust and airborne particles, though the supplier does not state a specific MERV rating or efficiency percentage at 0.3 microns. The housing is designed for compatibility with standard HVAC installations, with dimensions and flange details to be confirmed directly with the supplier.

The filtration media is typically a blend of micro-glass fibres or synthetic melt-blown polypropylene, graded for sustained airflow resistance across the filter's service life. Separator-style HEPA construction is standard for applications where mechanical integrity of the pleat pack matters more than compactness; this contrasts with mini-pleat or V-bank designs. The supplier notes durable materials, but does not specify frame construction (galvanised steel, aluminium, or MDF) or sealant type. Typical pressure drop at rated airflow for this class of filter ranges from 250 Pa to 350 Pa when clean, rising to 450 Pa at recommended change-out, though Sincerehope does not publish these figures.

Buyers for this product include facilities management contractors, pharmaceutical cleanroom operators, hospital engineering departments, and OEMs of air-handling units. The supplier indicates suitability for manufacturing, healthcare, and residential settings. Trade terms mentioned include FOB and CIF, with payment by L/C or T/T. MOQ is described as flexible, which buyers should translate into a written quantity and pricing schedule. No lead time is stated; importers should request production and shipping timelines for their order volume.

Sincerehope Industry Co., Ltd is headquartered at Room 503, Unit 1, No. 280 Long Heng Road, Shanghai 200232, China. The supplier is listed as an imported-tier account with a harbor trust tier, which represents the platform's baseline verification level. Notably, the response rate is recorded at 0.00 percent with an average response time of zero hours, indicating no historical inquiry responses are logged on the platform. This absence of response data is a material gap that buyers must weigh when assessing communication reliability.

The company profile does not disclose manufacturing footprint, number of employees, revenue, client references, or years in operation. The listing positions Sincerehope as a source of air filtration products for industrial, healthcare and residential markets, but offers no evidence of installed base or sector-specific accreditations such as ISO 14644 for cleanroom supplies or medical device registrations. Buyers should conduct independent due diligence, including verification of business licence, factory audit, and sample evaluation, before committing to volume orders.
