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
High-efficiency humidification: Microporous structure generates fine bubbles, increasing contact area by 50%, with humidification efficiency superior to traditional aeration tubes.
Significant Noise Reduction: Bubble rupture noise reduced by over 10 dB, improving the ward environment.
Zero Contamination Risk: Medical-grade PE contains no CNase/DNase and is SGS-certified (e.g., CANEC1818655002).
Cross-Contamination Prevention: A hydrophobic layer blocks humidification fluid backflow, preventing oxygen pipeline contamination.
Flexible customization: Supports non-standard sizes (e.g., irregular shapes, multi-layer structures) and functional adjustments (e.g., adding activated carbon).
Lifespan of 6–12 months (under normal use), with low maintenance costs.
Humidification Bottle Filters Application
| Field | Application Scenario | Function |
|---|---|---|
| Medical oxygen supply | Hospital central oxygen supply systems, home oxygen concentrators | 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 (FAQ)
They are made of medical-grade ultra-high molecular weight polyethylene (PE). This material is non-toxic, highly stable, and resistant to strong acids and alkalis.
By utilizing a dual-layer structure (macroporous and microporous layers), they produce finer bubbles. This refines bubble rupture and reduces noise levels by over 10 dB, improving noise reduction by 30%.
Yes, while the standard size is 10×7×39 mm, they can be customized into tubular, disc-shaped, or irregular shapes to fit specific humidifier bottle structures.
They feature a specialized hydrophobic layer that blocks the backflow of humidification fluids, preventing potential contamination in the oxygen pipeline.
Under normal operating conditions, the filters have a service life of 6 to 12 months, which helps maintain low maintenance costs.
