Humidification Bottle Filters Production Process
Humidifier bottle filter core production combines sintering technology with quality control, completed in five steps:
Screen ultra-high molecular weight PE particles, clean to remove impurities, and dry.
Sintering forming: PE particles are filled into a mold and sintered under high temperature (200–300°C) and pressure to form a microporous structure.
Wet forming (optional): PE fibers are mixed with a binder (such as PVA) to form a slurry, which is then molded or coated, followed by drying and curing.
Surface modification: Immersed in acid/alkali solutions to enhance surface functional group adsorption.
Activation treatment: Mild activation at 600–900°C in an inert gas environment to restore porosity.
Seal integrity test (0.5 MPa pressure), filtration efficiency verification (98% or higher retention of 0.5 μm particles), and pressure resistance test.
Rinsing with deionized water until conductivity <10 μS/cm, drying at 60–100°C, and dust-proof packaging.
Humidification Bottle Filters Advantages
Humidification Bottle Filters Application
| Field | Application Scenario | Function |
|---|---|---|
| Medical oxygen supply | Hospital central oxygen supply systems, home oxygen commentators | Humidify and dry oxygen to protect respiratory mucous membranes |
| Emergency and Intensive Care | ICU, Emergency Department, Respiratory Department | Used with disposable humidification bottles to prevent cross-infection |
| Portable Medical Devices | Oxygen bags, portable ventilators | Integrated with small filter cores (e.g., 5mm diameter) for lightweight design |
| Industrial Gas Processing | Gas filtration, laboratory gas line purification | Corrosion-resistant for chemical waste gas treatment |
Humidifier bottle filters combine materials science and precision manufacturing to address the three major pain points in medical oxygen therapy: humidification efficiency, noise, and infection control. Future trends include the application of nanomaterials (e.g., TiO₂ loading for enhanced sterilization) and intelligent production (real-time monitoring of process parameters), further expanding into high-end medical and environmental protection fields.
Frequently Asked Questions
They are made from medical-grade Ultra-high molecular weight polyethylene (PE), which is non-toxic, highly chemically stable, and resistant to strong acids and alkalis.
Yes, we offer customizable sizes and shapes (such as tubular, disc-shaped, or irregular structures) to fit different designs of humidifier bottles.
The microporous structure generates extremely fine bubbles, which increases the contact area and reduces bubble rupture noise by over 10 dB.
The filter incorporates a hydrophobic layer that blocks liquid backflow, ensuring humidification fluid does not contaminate the oxygen pipeline.
Under normal operating conditions, these medical-grade filters have a typical lifespan of 6 to 12 months with low maintenance costs.
