Suzhou-based manufacturer of appliance filters and replacement components. HIFINE's offer combines pleated filter construction, frames and seals with sample-led development for air purifiers, vacuum cleaners and recurring private-label supply.
What the published manufacturing scope means for a buyer.
HIFINE identifies its operating company as Suzhou Hifine Environmental Protection Technology Co., Ltd. Its About page dates establishment to March 2013 and separates the main filter factory from a Taizhou dust-bag operation and an overseas business branch in Vietnam. The manufacturing material describes media slitting and pleating, frame assembly, adhesive application, curing, sealing and testing. This makes the practical purchasing focus a complete filter assembly—not an efficiency label alone—with geometry, seals and airflow requirements carried into an approved sample and repeat-order specification. [1]
The quality page lists filter-production and injection-molding lines. The custom-development pages connect media, pleat design, plastic or other frames, gaskets and packaging. This is relevant where a replacement must fit an existing appliance housing while preserving the agreed airflow and resistance. [2]
HIFINE accepts drawings, physical samples, dimensions and part references. Its published sequence moves from requirement review through filter engineering and prototype approval to production, providing a useful basis for defining which sample and drawing revision govern repeat orders. [3]
Its range spans particle filters, activated-carbon layers, vacuum filters and humidifier wicks. These are different functions and constructions: an adsorption layer or absorbent wick should not inherit a HEPA performance claim merely because it appears in the same catalogue. [4]
CNFX synthesis of the company’s published information.
The catalogue is strongest on appliance-related filter assemblies and compatible replacement programs. Category links below are CNFX navigation, not a specification for every listed model.
Pleated particle-filter constructions include rectangular, deep-pleat and circular cassette formats. The cassette pages describe frame geometry, sealing surfaces, media area and optional carbon layers as coordinated design choices. Request the finished assembly's test conditions alongside the media specification. [5]
The purifier range describes granular and honeycomb carbon structures, including combinations with particle filters. Selection should identify the target contaminant, available space, airflow and acceptance method rather than infer gas-removal performance from a carbon label. [4]
The vacuum offer distinguishes washable and non-washable constructions, while the robot-vacuum range adds brushes, dust-collection parts and mop accessories. Confirm each component's model fit and supply responsibility. Compatible replacement descriptions do not establish an affiliation with the appliance brand. [6]
Humidifier development concerns absorption, cartridge geometry, water conditions and airflow. The separate commercial-HVAC offer covers panels, pockets and higher-efficiency configurations based on dimensions and resistance. These extensions should be specified independently of the household purifier range. [7]
Published processes, organized by production stage.
Supply the appliance model, filter position, housing and filter drawings, seals, service access and a reference sample where available. [5]
Review media, pleat geometry, frame, adhesive, gasket, target airflow and pressure drop together. Record the approved sample and test plan before tooling or volume commitments. [3]
The published process proceeds through media slitting and pleating, frame assembly and gluing, curing and sealing, then testing and packing. Changes to media or structure should be agreed against the approved configuration. [2]
Specify SKU references, labels, kit contents, packaging, inspection records and revision control. HIFINE offers private-label and recurring wholesale programs; confirm the commercial schedule for the actual design. [3]
The useful quality discussion is which finished assembly is tested, at what airflow, and how production remains tied to the approved sample.
HIFINE describes incoming checks of media, adhesive and frames; in-process checks during pleating, assembly and gluing; finished-filter visual and performance checks; and outgoing sampling. Agree the batch records and acceptance criteria required for the order. [2]
A media grade does not by itself describe leakage around the frame or the performance of a complete appliance. Include finished-filter efficiency, airflow, pressure drop, sealing and any appliance-level validation in the specification. Washable designs also need an agreed cleaning and retest procedure. [5]
The quality page displays partially redacted report images. For a documented procurement program, request the complete applicable report, sample identification, test method and current manufacturing-site documents as part of technical approval. [2]
These are supply scenarios described by the company, not independently confirmed customer endorsements.
A custom cassette can be developed around the fan, housing, filter position and replacement access. The purchasing decision connects the complete assembly's performance with the physical envelope and recurring replacement SKU. [5]
A distributor can organize multiple appliance references into approved samples and labeled kits. Model-by-model fit, correct contents and revision tracking matter more than a broad claim of compatibility across a brand. [8]
The HVAC program is framed around the installed equipment's dimensions, airflow, media and seals, with prototype review before recurring supply. It is a separate specification exercise from household filter selection. [9]
CNFX procurement assessment.
HIFINE is relevant to appliance brands, aftermarket distributors and private-label businesses that need filter assemblies developed from a drawing or reference sample. Its published manufacturing process provides a basis for discussing media conversion, molded structures and assembly. Compare offers against the same fit, airflow, pressure-drop, test and packaging requirements; the lowest unit price may otherwise reflect a different media area, seal or supplied kit.
