Overview

The CSpring ULTRA Filter Kit is a triple-layer filter system built to improve air quality in ResMed AirSense and AirCurve 10 and 11 machines. It includes an adapter and five high-capacity filters that combine carbon, HEPA, and composite fiber layers to trap particles and reduce odors more effectively than standard filters.

This filtration setup helps remove allergens, fine dust, and volatile organic compounds (VOCs) from the air before it reaches your PAP device. Cleaner air can support better sleep quality and reduce the chance of irritation from airborne contaminants, especially for those sensitive to dust or allergens.

A small upgrade that makes a noticeable difference in every breath.

The pleated design increases surface area, helping each filter last longer while maintaining airflow up to 100 L/min. Ideal for anyone looking to improve air intake during therapy without changing the core equipment. Just install the adapter, pop in the filter, and breathe a little cleaner each night.

  • Replace every 1–3 months, or sooner in dusty environments.
  • Designed as supplemental filtration. Not a medical replacement.
  • Not FDA-cleared; consult your physician before modifying CPAP equipment.

Three-Stage Filtration System

Each filter combines a carbon pre-filter, H13-grade HEPA core, and non-woven composite post-filter. These layers work together to remove coarse dust, fine particles, and volatile organic compounds before air enters the CPAP machine. The design improves overall air quality without altering pressure delivery or requiring changes to your therapy setup.

Captures Particles as Small as 0.3 Microns

The HEPA core meets H13 standards, filtering out at least 99.95% of particles measuring 0.3 microns or larger. This includes allergens, dust, mold, and certain bacteria. Cleaner intake air may reduce nasal irritation or discomfort caused by low-quality filtration in dusty or high-pollution environments.

Reduces Odors and Airborne Irritants

The carbon layer helps absorb odors and VOCs while also catching larger particles like pet hair or lint. This added layer is useful for neutralizing everyday smells from the surrounding room and can contribute to a fresher sleep environment without using scented products or chemical treatments.

Pleated Filter Design Increases Surface Area

Each filter includes a pleated structure with approximately 64.8 cm² of filtration surface. This allows the filter to trap more particles without clogging quickly. It also helps maintain airflow for longer periods, making it suitable for daily therapy in homes with varying air conditions.

Maintains High Airflow Performance

The filter is rated to support airflow up to 100 liters per minute. This ensures compatibility with standard and auto-adjusting pressure settings without restricting performance. It helps deliver consistent therapy while also improving the quality of the air entering the CPAP machine.

Includes Adapter for Quick Installation

This kit comes with a CS ULTRA adapter that fits into the filter compartment of ResMed AirSense and AirCurve 10 and 11 devices. Once installed, filters can be inserted and replaced without altering the machine or requiring tools. The adapter holds the filter in place for a secure fit.

Five Filters Included in the Kit

The package includes three standard filters plus two bonus replacements, for a total of five. This provides several months of coverage depending on the environment. Filters typically last one to three months, though homes with pets, dust, or open windows may require more frequent changes.

Designed for ResMed Compatibility

The filter system is specifically built for ResMed AirSense and AirCurve 10 and 11 devices. It does not fit other machines and is only compatible when used with the included CS ULTRA adapter. The adapter ensures proper alignment and airflow for safe, stable use.

Not Intended for Medical Diagnosis or Treatment

This filter kit is designed to improve air intake quality but is not FDA-cleared. It is not a medical device and does not replace prescribed components. Anyone with concerns about modifying their equipment should speak with a healthcare provider before introducing additional filtration.

Supports General Air Quality

This system is designed to also enhance the quality of the air being breathed in. The triple-layer design offers broader filtration coverage for those seeking added cleanliness without replacing the CPAP unit itself.

Important Tips

  • Install the included adapter before inserting any CPAP ULTRA filter, it won’t fit otherwise.
  • Every pack includes five filters, replace one every 1–3 months depending on your air quality.
  • Flip the first filter every two weeks to help redistribute dust and extend filter life.
  • Use alongside a CPAP cleaning machine to keep both filter housing and tubing hygienic.
  • Use distilled water to maintain humidifier function without compromising airflow.
  • Keep a backup set of filters stored in a clean, dry spot for easy replacement when needed.
  • Clean filter adapter monthly, wipe with CPAP wipes to remove trapped dust before inserting a new filter.
  • Check filter color and odor, if it appears discolored or smells musty, replace immediately.
  • In dusty environments, change the filter more frequently to prevent airflow restriction.
  • While the filters aren’t FDA-cleared, they offer advanced airborne protection, consult your provider before upgrading.
  • Use alongside CPAP tubing covers to protect the hose from condensation and keep lines clear.
  • Pair with a CPAP cleaning brush set to maintain all components of your mask cycle.
  • If the machine becomes louder, the filter may be clogged, inspect and replace if necessary.
  • For easier refills, use the part finder to select compatible CPAP accessories and filters.
