Breathing Filters
HMEF, bacterial and viral, tracheostomy and spirometry filters for circuit protection
Every Breathing Filters Item We Supply
Four filters, four jobs. The HMEF filters and returns moisture so it can replace an active humidifier. The BV filter filters only, for circuits that already have humidification. The tracheostomy filter is a 7 g HME for spontaneously breathing stoma patients. The spirometry filter protects a lung function machine at a resistance low enough not to distort the reading.

View Product →Problems This Range Solves
- Dry inspired gas drying the airway during ventilation
- Cross contamination between patient and ventilator circuit
- Dead space too large for paediatric tidal volumes
- Filter resistance distorting lung function test readings
Who It Is For
- ICU and anaesthesia department buyers
- Lung function laboratories and respiratory clinics
- Breathing circuit kit assemblers
Core Advantages

- Lung function testing and occupational health screening
Industries We Supply From Breathing Filters
Hospitals And Clinics
Hospital procurement carries the widest specification burden of any buyer in this market: every ward wants a different configuration, and every one of them has to be sourced, certified and stocked.
Emergency And Pre Hospital Services
Pre-hospital buyers specify for the worst case: a device used one handed, in a moving vehicle, by someone who cannot stop to read a label. That pushes the specification toward colour coding, one-hand operation and kink resistance.
Home And Long Term Care
In home and long term care the device is worn for weeks rather than hours, and it is handled by a carer rather than a clinician. That changes the specification: comfort, discretion and tolerance matter more than peak performance.
Questions About Breathing Filters
What is the difference between an HMEF and a BV filter?
Both filter. The HMEF also returns moisture, so it can replace an active humidifier. The BV filter provides filtration only.
Which filter suits a tracheostomy patient breathing spontaneously?
The tracheostomy filter, at 7 g with 15 ml dead space and a 15F connector.
What connections do the circuit filters use?
22M/15F-22F/15M on the HMEF and 22M/15F-15M/22F on the BV filter.
How are the filters sterilised?
The tracheostomy and spirometry filters are EO sterilised.
Which filter should I use for spirometry?
The spirometry filter, sized to the mouthpiece and kept at 15 Pa at 30 l/min so readings are not distorted.
