Respironics BiPAP Auto M Series Reusable Pollen Filter — Pack of 2

SKU: 1029330  |  UPC: 700819623987  |  By Philips Respironics

Reusable Foam Pollen Filter  |  Pack of 2  |  Fits All M Series & PR System One CPAP/BiPAP & SleepEasy  |  Washable & Reusable  |  Catches Pollen, Dust & Dander  |  By Philips Respironics

The genuine Respironics reusable pollen filter for all M Series and PR System One CPAP and BiPAP machines — the washable foam outer pre-filter that catches pollen, dust, and pet dander before air enters the machine's intake. Keeping the pollen filter clean and in good condition protects the machine's internal components, maintains consistent airflow and pressure delivery, and prevents larger airborne particles from reaching the finer inner filtration layer or the patient's airway. Reusable and washable — this foam filter is rinsed, dried, and replaced in the machine rather than discarded after each use. Pack of 2 allows one filter to be cleaned and drying while the other is in use. Compatible with all Philips Respironics M Series CPAP and BiPAP machines, all PR System One CPAP and BiPAP machines, and the Respironics SleepEasy Integrated CPAP machine and heated humidifier. SKU 1029330. By Philips Respironics.

Specifications

Note: the pollen filter is the outer reusable foam filter. The M Series also uses a separate inner disposable ultrafine filter for smaller particles — both are recommended for complete filtration. Call 1-866-218-0902 for disposable ultrafine filter availability.

Key Features

• Reusable foam construction — the pollen filter is a soft foam pad that catches larger airborne particles; rinsed with warm water, allowed to air dry completely, and reinserted — not discarded after each use
• Catches pollen, dust, and pet dander — filters larger airborne particles from the intake air before they enter the machine's motor, internal components, or the patient's breathing circuit
• Protects internal machine components — accumulated particulate debris in the machine's motor and blower assembly degrades performance and can shorten machine service life; the pollen filter reduces this accumulation
• Pack of 2 — the two-filter pack supports a practical rotation: while one filter is rinsed and air-drying (which requires full drying before reinsertion to prevent mold and moisture in the machine), the second dry filter can be inserted for uninterrupted use
• Universal M Series and PR System One compatibility — fits all M Series and PR System One platform machines; a single part number covers the full Respironics CPAP/BiPAP line on this platform
• Genuine Respironics replacement — original Respironics part with confirmed fit and filtration specification for the M Series filter housing

Clinical FAQs

What is the difference between the reusable pollen filter and the disposable ultrafine filter, and does the M Series need both?

The Respironics M Series CPAP and BiPAP machines use a two-stage filtration system at the air intake. The outer reusable pollen filter (this product, SKU 1029330) is the first stage — a foam pre-filter that catches larger airborne particles: pollen grains, household dust, pet dander, and coarser environmental particles. It is positioned at the exterior of the intake housing, washed regularly, and replaced as a reusable component. The inner disposable ultrafine filter is the second stage — a finer, paper-like or electrostatic filter that catches smaller particles including fine dust, smoke particles, and microorganisms that pass through the pollen filter; it is not washable and must be discarded and replaced on a regular schedule. The manufacturer's recommendation is to use both filters in conjunction: the pollen filter handles the larger particles and reduces the burden on the ultrafine filter, extending the ultrafine filter's effective lifespan. Running the machine without either filter — particularly the pollen filter — allows accumulated dust and debris to enter the motor and blower assembly, where it can degrade performance and shorten the machine's service life. Most CPAP supply schedules recommend replacing the reusable pollen filter every 6 months and the disposable ultrafine filter every 30 days, though frequency should be adjusted based on the household's dust, pollen, and pet dander levels.

How do I clean the reusable pollen filter correctly?

Remove the pollen filter from the machine's intake housing — the exact location varies by M Series model but is always at the rear or side air intake opening. Rinse the filter under warm running water to dislodge accumulated dust and debris; gently squeeze and release the foam to flush the particulate through. Do not use soap, household cleaning products, or disinfectants on the foam filter — these can leave residue that affects air quality or degrades the foam material, and they are not necessary for effective cleaning of a pollen pre-filter. After rinsing, gently squeeze out excess water and allow the filter to air dry completely before reinsertion — this is the critical step that the two-pack addresses: a damp filter reinserted into the machine introduces moisture to the motor and interior, which can promote mold growth and damage internal components. Dry time varies depending on ambient humidity and temperature, but allow at least several hours and ideally overnight. Check the filter after drying — if it retains a gray or dark appearance that does not resolve with rinsing, or if the foam feels degraded, compressed, or no longer springs back to shape, replace the filter rather than continue using it. The two-pack provides a ready replacement.

How do I know when the pollen filter needs to be replaced rather than just washed?

The reusable pollen filter is designed for multiple wash cycles and long-term use, but it does not last indefinitely. Signs that the filter should be replaced rather than washed again: the foam material no longer springs back to its original shape after drying — permanent compression means it no longer fills the filter housing and creates a proper seal, allowing unfiltered air to bypass the filter around the edges; discoloration or darkening that persists after thorough rinsing indicates embedded particulate that washing cannot remove; tears, holes, or structural damage to the foam allow particles to pass through unfiltered; a persistent odor after drying suggests biological growth within the foam. Most CPAP supply schedules recommend proactive replacement every 6 months regardless of apparent condition — a small consumable cost relative to the cost of motor damage from long-term unfiltered intake air. Insurance coverage for CPAP replacement filters varies by plan; many plans cover replacement filters on a scheduled basis.
