3A Antibacterial Filter - Single Use Sterile Hydrophobic Medical Filter for Suction and Respiratory Equipment
The 3A antibacterial filter is a single use, sterile medical air filter designed for effective bacterial and particle filtration in clinical and community healthcare settings.
The hydrophobic membrane resists fluid ingress, protecting downstream equipment and maintaining consistent airflow throughout the procedure.
Each filter is individually sealed to maintain sterility and support quick, clean installation on medical suction and respiratory devices.

Frequently asked questions
What is a 3A antibacterial filter used for?
The 3A antibacterial filter is a single use medical air filter used to provide bacterial and particle filtration on medical suction and respiratory equipment. It is commonly used in ENT clinics during ear wax removal and microsuction, in GP surgeries, hospitals and outpatient settings where infection control between patients is essential. The hydrophobic membrane helps resist fluid ingress and protects downstream equipment.
How often should a 3A antibacterial filter be replaced?
The 3A antibacterial filter is a single use device and should be replaced after each patient. It should also be replaced immediately if airflow resistance increases during use, which may indicate the filter is saturated or blocked. Do not reuse or attempt to clean and reinstall a used filter.
What equipment is the 3A antibacterial filter compatible with?
The 3A antibacterial filter is compatible with a range of medical suction units and respiratory devices used in clinical settings. It is commonly used with 3A professional aspirators and similar suction equipment in ENT, audiology and primary care. Always verify connector compatibility with your specific device before use.
What does hydrophobic mean in a medical filter?
A hydrophobic membrane in a medical filter means the material actively repels water and fluid. This is important in suction and respiratory applications because it prevents fluid from passing through the filter and contaminating downstream equipment or tubing. A hydrophobic filter maintains its filtration efficiency even when exposed to moisture during clinical procedures.
Is the 3A antibacterial filter sterile?
Yes. Each 3A antibacterial filter is supplied sterile and individually sealed to maintain sterility until the point of use. Check that the individual packaging seal is intact before opening. Once opened, the filter should be used immediately and not stored for later use.
Can the 3A antibacterial filter be used in ENT microsuction?
Yes. The 3A antibacterial filter is suitable for use with suction equipment used in ENT microsuction and ear wax removal procedures. Fitting a fresh filter between patients supports infection control and protects the suction unit from contamination. Always follow your clinic’s infection control protocol when selecting and changing filters.
