Medical Equipment Ultrasonic Disinfecting Dust Filter Sponge Class I CE Certified Customizable Size Absorbing Hemostatic 3-Year

Polyurethane (PU) foam used in ventilator filter accessories is a key component of the ventilator filtration system. Leveraging the material properties of polyurethane foam— porous structure, excellent elasticity, good temperature resistance, and controllable filtration precision —it plays core roles such as filtration and purification, airflow buffering, and moisture-proof protection in the ventilator air circuit, and is adapted to the operating conditions of long-term ventilator operation. Its specific functions are as follows:

1. Graded filtration for air circuit purification
The pore size of polyurethane foam can be customized as needed to achieve coarse + medium efficiency graded filtration . On the one hand, it filters large particulate impurities such as dust, hair, and particulates from inhaled air; on the other hand, it blocks sputum, aerosols, and secretions in the exhaled gas of patients. This not only prevents impurities from entering the patient's respiratory tract and causing irritation or infection, but also stops pollutants from flowing back into the ventilator, protecting core components such as the fan and sensors from damage.

2. Airflow buffering and noise reduction
Polyurethane foam has good elasticity and porosity, which can buffer, decompress, and equalize the high-pressure airflow output by the ventilator, allowing the airflow to enter the patient's respiratory tract smoothly and reducing coughing and airway discomfort caused by direct airflow impact. At the same time, the porous structure can absorb turbulent noise generated when airflow passes through pipelines and filters, lowering the sound of the ventilator during operation and improving the comfort of patients using it at night.

3. Moisture resistance and hydrophobicity for equipment protection
Polyurethane foam has hydrophobic properties (which can be enhanced through process optimization), capable of effectively adsorbing and blocking water vapor and condensed water in exhaled gas. This prevents moisture from entering the ventilator and causing short circuits or corrosion of the movement, and also reduces bacterial growth caused by the accumulation of condensed water in the pipeline, extending the service life of ventilator accessories and the main unit.

4. Sealing and filling to improve filtration efficiency
The elastic property of polyurethane foam can tightly fill the gaps between the filter housing and the filter element, preventing unfiltered air from leaking into the air circuit and ensuring that all airflow passes through the foam filter layer, thus guaranteeing filtration efficiency structurally. Meanwhile, the elastic design makes the installation and replacement of the foam more convenient, adapting to the assembly requirements of filter accessories for different models of ventilators.

5. Temperature and aging resistance for long-term working conditions
Medical-grade polyurethane foam has good temperature resistance and aging resistance , able to adapt to the air circuit temperature (human body temperature ~40℃) during ventilator operation. It is not easy to deform, harden or shed debris after long-term use, avoiding secondary impurity pollution caused by foam damage, and meeting the stability requirements of medical consumables.

Supplementary note : Polyurethane foam can be customized into products with different densities, pore sizes and thicknesses according to the specification requirements of ventilator filters, and supports disposable sterile packaging . It is suitable for different usage scenarios of household and medical ventilators, which is also an important advantage of it as a ventilator filter accessory.
