Quick answer: This is the genuine ResMed hypoallergenic air inlet filter for the Stellar ventilator (1-pack, part 24933; 12-pack = 24934) — the framed filter that fits the air-inlet on the back of the device to filter the air entering the machine, protecting it from dust, particles, and allergens. The hypoallergenic design combines two layers — one side blocks fine particles, the other blocks larger particulate matter. It fits the Stellar 100 and Stellar 150. Easy to remove and install. No prescription required.
What's included
- 1 × ResMed Stellar hypoallergenic air inlet filter (with frame, part 24933)
Ventilator not included. (12-pack available as 24934.)
About this part
Every Stellar ventilator draws room air in through an inlet on the back of the device — and this filter cleans that incoming air before it reaches the machine:
- Protects the device — traps dust, particles, and allergens from the room air so they don't enter the ventilator.
- Hypoallergenic, two-layer — a combination of materials: one side blocks fine particles, the other wards off larger particulate matter — finer filtration than a standard filter.
- Framed for easy handling — the filter comes in a frame for quick, clean removal and installation.
- Routine replacement — replace regularly (per the Stellar user guide) to maintain airflow and protection.
Compatibility: ResMed Stellar 100 and Stellar 150 ventilators.
Important — this is the air INLET filter (not the anti-bacterial filter)
Don't confuse the two Stellar filters:
- This part (24933/24934) — the hypoallergenic air inlet filter that protects the device from incoming room dust/allergens (fits the back of the machine).
- Anti-bacterial filter (24966) — a different, inline filter that fits at the air outlet between the device and the breathing circuit, providing bacterial/viral protection for patient and device (requires a "Learn Circuit").
Both may be used, for different purposes. Order the one you need.

Frequently asked questions
What does this filter do? It fits the air inlet on the back of the Stellar and filters the room air entering the device, protecting the machine from dust, particles, and allergens.
Which devices does it fit? The ResMed Stellar 100 and Stellar 150.
How is it different from the anti-bacterial filter (24966)? This is the inlet filter (protects the device from incoming dust/allergens). The anti-bacterial filter (24966) is a separate inline filter at the air outlet that provides bacterial/viral protection for patient and device. Different parts, different jobs.
What does "hypoallergenic" mean here? It's a two-layer filter — one side blocks fine particles, the other larger particulate — for finer filtration than a standard filter.
Is this a single filter? Yes — 1-pack. A 12-pack is available as 24934.
How often should I replace it? Regularly, per the Stellar user guide — sooner if it looks dirty or discolored.
Do I need a prescription? No — filters do not require a prescription.
Can I get it 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.
Replace the filter regularly per the Stellar user guide to protect the device and maintain airflow. Do not run the device without a filter fitted.
