Quick answer: These are pediatric heat and moisture exchange (HME) filters, supplied in a 50-pack (part 24969). An HME — sometimes called an "artificial nose" — sits in the breathing circuit near the patient: it captures heat and moisture from exhaled air and returns them on the next breath, while its filter media helps keep the circuit clean. This is the pediatric size, with a smaller internal volume suited to smaller tidal volumes. Single-patient, disposable — replace per the manufacturer's instructions and your clinical protocol.

Breathing circuit, ventilator, and patient interface not included.
About these filters
When a patient breathes through a ventilator circuit, the normal warming and humidifying work of the nose and upper airway is bypassed. An HME restores some of that passively: as the patient exhales, the media captures warmth and moisture; on the next inhalation, that warmth and moisture return to the delivered gas. This helps keep secretions from drying out, without needing an active heated humidifier. The filter element additionally helps keep contaminants out of the circuit.
The pediatric version matters because size is not cosmetic here: a pediatric HME has a smaller internal volume (less dead space) and lower resistance, matched to smaller tidal volumes. An adult HME used on a pediatric patient adds proportionally far more dead space. The correct size is specified by the clinical team.
A 50-pack is the practical fulfillment size for pediatric units, home-care agencies, and anyone changing HMEs on a routine schedule.
Key features
- Heat and moisture exchange — passive humidification, no power or water needed.

Use & safety notes
Fit the HME in the position specified in your circuit setup — normally between the patient interface and the circuit. Replace it per the manufacturer's instructions (commonly every 24 hours, and sooner if it becomes visibly soiled, wet, or resistant to flow), because a saturated or clogged HME increases breathing resistance — a particular concern in pediatric patients. Do not use an HME together with active heated humidification unless your clinical protocol specifically allows it, as the combination can saturate the HME. Monitor for increased resistance and follow your clinical team's guidance.
Frequently asked questions
What is an HME filter? A passive "artificial nose" that captures heat and moisture from exhaled breath and returns them on the next inhalation, with filter media that helps keep the circuit clean.
How many are in the pack? Fifty.
What's the difference between the pediatric and adult versions? The pediatric HME has a smaller internal volume (less dead space) and is matched to smaller tidal volumes. The adult version is part 24967. The correct size is specified by the clinical team.
How often should it be changed? Typically every 24 hours, and sooner if it becomes visibly soiled, wet, or harder to breathe through. Follow the manufacturer's instructions and your clinical protocol.
Can I use it with a heated humidifier at the same time? Generally no — the combination can saturate the HME. Follow your clinical team's protocol.
Do I need a prescription? Yes — respiratory consumables are used under clinical direction. Confirm your setup with your provider.
Can I get them delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
For use under clinical direction. Follow the manufacturer's instructions for use and replacement, and your provider's or facility's protocol. Replace immediately if breathing resistance increases or the device becomes soiled or saturated.
