Fisher & Paykel SleepStyle+ Ultra-Fine Filters - Pack (3+1)

The Fisher & Paykel SleepStyle+ Ultra-Fine Filters Pack (3+1) is the genuine high-efficiency two-stage filter pack for the F&P SleepStyle+ Auto CPAP machine. The pack contains 3 ultra-fine filters and 1 standard air filter (4 filters total) — together delivering 99% filtration efficiency at 0.5–0.7 micron particles, capturing dust mites, pet dander, fine pollen, and other airborne allergens that the standard filter alone can't catch. Ideal for allergy and asthma sufferers, pet owners, and users in higher-pollen environments.

Key Features

• 99% filtration efficiency at 0.5–0.7 microns: Captures dust mites, pet dander, fine pollen, and other small airborne allergens — much finer particles than the standard filter alone.
• Two-stage filter system: Standard pollen filter at the air intake, ultra-fine filter behind it for second-stage filtration.
• Pack contents: 1 standard air filter (the same as the 900SSP114) + 3 ultra-fine filters — covering one full standard-filter cycle and three ultra-fine cycles.
• Thumbgrip tabs on the standard filter: Easy removal and installation without fumbling at the back of the machine.
• Disposable, latex-free: Replace rather than wash — single-use design.
• Genuine F&P: Manufacturer-specified part 900SSP112.

How the Two-Stage Filter System Works

The SleepStyle+ uses two filters working together. The standard pollen filter sits at the back-mounted air intake and handles the larger airborne particles — dust, pollen, and pet hair. The ultra-fine filter sits behind it and adds a second stage of finer filtration, catching the small particles that pass through the standard filter. Both filters slide into the same compartment at the back of the machine.

This pack is sized to keep the system running for several months — typically the standard filter and one ultra-fine are installed at the same time, with the additional ultra-fines replaced on a more frequent cycle.

Compatibility

For use with the Fisher & Paykel SleepStyle+ Auto CPAP machine only.

Not compatible with the older SleepStyle (non-plus) machine. The original SleepStyle uses differently-shaped filters — see the F&P SleepStyle Filters page for the correct part. Check the model badge on your machine — "SleepStyle+" or "SleepStyle Plus" means this is the right pack.

Standard or Ultra-Fine — Which Pack?

F&P sells two filter products for the SleepStyle+. The SleepStyle+ Filters 2-Pack (900SSP114) contains 2 standard filters only — the right pick if you don't need finer filtration and just want the standard replacement. The Ultra-Fine Filter Pack (this product) adds the second-stage 99% filtration of finer particles — worth the upgrade if you have allergies, asthma, pet dander sensitivities, or want to capture dust mites and fine pollen.

Replacement Schedule

F&P recommends replacing the SleepStyle+ filters approximately every 1–3 months — closer to monthly with pets, allergies, or in dustier environments, and up to 3 months in cleaner indoor settings. Replace sooner if you notice visible discolouration, dirty patches, or a drop in airflow. Check the filters weekly as a habit, and replace immediately if exposed to liquids or visible debris.

Important — Do Not Wash

Both the standard and ultra-fine filters are disposable, not washable. Attempting to wash, rinse, or vacuum them damages the fibre matrix and reduces filtration effectiveness. Replace on schedule rather than try to clean.
