The ventilator filter cotton is made of polyester non-woven fibers formed by heat-pressing and ultrasonic edge-sealing. This product effectively filters PM2.5 fine particles and dust, is made of polyester super-fine spun fibers, and features hypoallergenic, odorless material with ultra-fine pore sizes, achieving a filtration efficiency of over 98% for 7-8 micrometer dust. Its stiffness ensures it will not deform under the suction force generated by the fan, making it primarily applicable to ventilator air filters.
Design Advantages: This design not only provides effective heat and moisture exchange but also deeply purifies the air entering the respiratory tract, while heating and humidifying it to reduce particle blockage in the catheter and decrease airflow resistance.
Lightweight Material: Made of lightweight materials, it reduces the accumulation of toxic substances on the tracheostomy catheter, ensuring smooth breathing for patients.
Convenient Oxygen Delivery: With a simple design, it facilitates oxygen delivery and ensures patients' breathing remains unobstructed.
High-Efficiency Particulate Filtration: Effectively filters PM2.5 fine particles and dust.
Material Safety: Constructed from ultra-fine spun-bond polyester fiber. The material is non-allergenic and odorless.
Superior Filtration Efficiency: Features an ultra-fine pore structure achieving ≥98% filtration efficiency for dust particles sized 7-8μm.
Structural Integrity: Possesses sufficient rigidity/stiffness to prevent deformation under the suction force generated by the ventilator's blower/fan assembly.

Single-Use Consumable: This product is a single-use medical consumable. Cleaning and reuse are strictly prohibited. Replacement frequency is dependent on the usage environment.
Replacement Schedule: Replacement intervals should be determined based on the home environment. Generally, replace every 1-3 months. Dust can be gently dislodged weekly by hand flicking.
Critical Replacement Indicator: Replace immediately if the filter membrane appears grey.
Consequences of Non-Replacement: Failure to replace an expired filter membrane will result in loss of filtration efficacy. Ingress of large dust particles into the ventilator can cause abrasive wear on the motor bearings, reducing motor lifespan and increasing motor noise levels.
