PP Sintered Oxygen Humidifier Bottle Inlet Filter | Medical Grade Replacement Filter

The PP sintered oxygen humidifier bottle filter is a core inlet filtration accessory specially used for medical oxygen humidifier bottles, oxygen concentrators and hospital central oxygen supply systems. Different from the bubble diffuser filter, this small PP filter is installed at the air inlet of the humidifier cap. It is designed to filter pipeline dust, particle impurities and residual debris before oxygen enters the humidification water, ensuring clean and safe oxygen inhalation for patients. As a standard replacement spare part, it is widely purchased by medical device manufacturers, medical distributors and oxygen equipment factories worldwide.

Product Material & Feature Advantages

Made of medical grade sintered polypropylene (PP), the filter features uniform micropore structure, stable air permeability and excellent chemical resistance. Unlike PE material, PP sintered filter has better rigidity, stronger compression resistance and is not easy to deform during high-speed air flow and assembly.

Key advantages as below:

• Medical Grade PP Raw Material – Non-toxic, odorless, no precipitation, safe for medical oxygen treatment, compliant with medical consumable standards.

• Effective Particle Filtration – Uniform micropores block pipeline dust, fine particles and sundries, effectively preventing water contamination and protecting patient respiratory health.

• High Air Permeability & No Blockage – Stable airflow under 1-10L/min oxygen flow rate, no air resistance, no affecting normal oxygen output.

• Strong Acid and Alkali Resistance – Resistant to common disinfectants and humidification solutions, reusable after cleaning, long service life.

• Precision Custom Size – Custom diameter, height and pore density to fit all kinds of oxygen humidifier bottle caps, tight installation without falling off.

Working Principle

When oxygen flows from the oxygen cylinder or oxygen concentrator pipeline, it first passes through the PP sintered inlet filter. The dense and uniform microporous structure intercepts all kinds of particulate impurities in the gas. After purification, the clean oxygen enters the humidifier water for humidification, avoiding impurity inhalation and reducing the risk of respiratory tract infection. At the same time, the PP filter can stabilize the airflow and reduce water splashing inside the humidifier bottle.
