Factory Direct Replacement CPAP Filters for ResMed AirSense 11 & AirCurve 11 Machines

Factory Direct Replacement CPAP Filters for ResMed AirSense 11 & AirCurve 11 Machines
As CPAP technology advances, modern sleep therapy devices like the ResMed AirSense 11 and AirCurve 11 demand even more precise filtration solutions. Unlike previous generations, the AirSense 11 platform uses a completely redesigned, compact air intake slot.

If you are a medical equipment distributor, sleep therapy clinic, or bulk buyer sourcing replacement consumables, here is a complete guide to high-efficiency replacement filters for the ResMed AirSense 11 series, brought to you by Huizhou Longwangda Technology Co., Ltd. (hmepaper.com).

1. Dimensional Compatibility: Precision-Engineered for AirSense 11
Precision sizing is essential to prevent unfiltered air from bypassing the filter frame and damaging internal blowers.

  • Exact Dimensions: 2 inch x 0.94 inch (51mm x 23mm).
  • Machine Compatibility:
    • ResMed AirSense 11 Series (AirSense 11 AutoSet, CPAP, Elite)
    • ResMed AirCurve 11 Series (AirCurve 11 VAuto, S, ST, ASV)
  • Size Difference Note: These filters are specifically engineered for 11-series devices and are not compatible with AirSense 10 or S9 models (which require larger 53mm x 35mm filters).
2. Advanced Multi-Layer Electrostatic Filtration Technology
Manufactured with medical-grade synthetic media from hmepaper.com, our disposable filter pads provide dual-stage protection for both machine motors and patient airways:

Feature Standard Disposable Filter Longwangda Premium Filter (hmepaper.com)
Dimensions 2" x 0.94" (51mm x 23mm) Exact OEM Fit (2" x 0.94" / 51mm x 23mm)
Media Type Basic Polyester Fiber Electrostatic Non-Woven Synthetic Fine Media
Filtration Target Coarse ambient dust Microfine Pollen, PM2.5, Dust Mites, Pet Dander
Pressure Drop Variable Ultra-Low Air Resistance (Optimized Intake Flow)
Application Household Maintenance Allergy Relief, Clinical Use, Bulk B2B Supply
3. Step-by-Step Replacement Guide for AirSense 11
Replacing the filter on an AirSense 11 unit is quick and straightforward. Clinic managers and home users should follow these three steps:

  1. Open the Machine Filter Door: Locate the air intake cover on the back/side of the AirSense 11 unit and remove the old dirty filter pad.
  2. Insert the New Filter: Place the fresh Longwangda 51x23mm filter in the exact same orientation as the original pad.
  3. Seal the Door Firmly: Ensure the intake cover clicks shut tightly to prevent unfiltered ambient air, dust, and fine particles from leaking around the edges.
Maintenance Frequency: Replace every 2 to 4 weeks under standard conditions, or every 1 to 2 weeks during peak allergy seasons or in environments with pets. Never wash or reuse disposable electrostatic filters.
4. Why Source AirSense 11 Consumables from hmepaper.com?
