The DreamStation Disposable Ultra-Fine Filter adds a second stage of fine-particle filtration to the DreamStation's air intake system for users who want more complete filtration beyond what the foam pollen filter alone provides. The white ultra-fine fiber medium, housed in a light blue plastic carrier, snaps onto the base of the installed dark blue foam pollen filter (1122446) — the two filters combine into one unit and are inserted together into the machine's filter slot. The ultra-fine filter catches smaller particles — fine dust, smoke particles, and microorganisms — that pass through the pollen filter's 7–10 micron mesh. Replace every 30 nights of use or when visibly dirty. Not reusable or washable — discard and replace. Available as a 1-pack (1122447) or 6-pack (1122519, a 6-month supply at one filter per month). FSA eligible. Made in USA. By Philips Respironics.

Specifications

The ultra-fine filter requires the foam pollen filter (1122446) to be installed — it snaps onto the pollen filter, not directly into the machine. Also need the pollen filter? See the DreamStation Reusable Pollen Filter (1122446). Call 1-866-218-0902 for availability and the 6-pack (1122519).

DreamStation Filter System — Complete Overview

Key Features

• Second-stage fine particle filtration — the foam pollen filter (1122446) catches larger particles at 88% efficiency at 7–10 micron; the ultra-fine filter catches smaller particles that pass through — fine dust, smoke particles, and microorganisms — providing a more complete filtration stack
• Snaps onto the base of the pollen filter — the light blue ultra-fine filter clips to the underside of the dark blue foam pollen filter; both are then inserted into the machine's filter slot as a single combined unit; the ultra-fine filter does not install directly into the machine without the pollen filter
• Light blue housing for easy identification — the lighter blue plastic carrier distinguishes the disposable ultra-fine filter from the darker blue reusable pollen filter; the two must not be confused as they install in different positions and have different maintenance schedules
• White ultra-fine fiber medium — permanently attached to the light blue carrier; the carrier and filter are not designed to be separated
• Disposable — replace every 30 nights — not washable or reusable; attempting to wash will damage the ultra-fine fiber structure and compromise filtration; replace the filter after every 30 nights of use regardless of visible condition, or sooner if visibly dirty
• 6-pack (1122519) provides a 6-month supply — at one filter per month (30 nights), the 6-pack covers 6 months of daily CPAP use; aligns with standard biannual CPAP supply orders
• Optional but recommended for sensitive users — particularly beneficial for users with fine particle allergies (smoke, fine dust, airborne mold spores at smaller particle sizes than the pollen filter handles), respiratory conditions, or immunocompromise
• HCPCS A7038 | FSA eligible | Made in USA | By Philips Respironics

Clinical FAQs

How does the ultra-fine filter install in the DreamStation and how does it work with the pollen filter?

The ultra-fine filter installs in a specific sequence: remove the dark blue foam pollen filter (1122446) from the machine's filter slot; snap the light blue ultra-fine filter onto the underside (base) of the foam pollen filter — it clicks into place on the pollen filter's frame; then slide both filters, now combined as one unit, back into the machine's filter slot. The combined unit positions the foam pollen filter as the outer first stage (catching larger particles as air enters) and the ultra-fine filter behind it as the inner second stage (catching smaller particles that passed through the foam). Air must pass through both filter media sequentially before reaching the machine's motor and blower. The ultra-fine filter should never be installed without the pollen filter — it snaps to the pollen filter's frame, not to the machine housing directly. When removing the combined unit to replace the ultra-fine filter, unsnap the old ultra-fine filter from the pollen filter frame, attach the new ultra-fine filter, and reinstall. The pollen filter remains in use until its own 6-month replacement schedule is reached.

Is the ultra-fine filter required, or can I use just the pollen filter?

The foam pollen filter (1122446) is the required filter — DreamStation machines must not operate without it. The ultra-fine filter (1122447) is explicitly described by Philips Respironics as an optional accessory for increased filtration efficiency. A DreamStation operates within its designed specifications using only the pollen filter, and for many users in typical household environments with normal air quality, the pollen filter's 88% filtration at 7–10 micron provides adequate protection for both the machine and the patient. The ultra-fine filter adds meaningful value for specific user situations: households with significant fine particle exposure (tobacco smoke, wood smoke, construction dust, high urban air pollution), users with fine particle allergies or respiratory sensitivities where submicron particle filtration is clinically beneficial, and immunocompromised users where pathogen load reduction in therapy air is a health priority. The 30-day replacement schedule and cost of the ultra-fine filter should also factor into the decision — users who would not consistently replace it on schedule may receive more consistent protection from the pollen filter alone, maintained well, than from an overdue ultra-fine filter left in place too long.

What is the HCPCS code for the ultra-fine filter and does insurance typically cover it?

The DreamStation Disposable Ultra-Fine Filter (1122447) carries HCPCS code A7038 — the standard CPAP billing code for disposable filters. The companion foam pollen filter (1122446) uses HCPCS A7039. Both A7038 and A7039 are recognized DMEPOS billing codes under Medicare Part B and most commercial insurance plans' CPAP supply coverage. Medicare and many insurance plans cover CPAP replacement supplies on a defined schedule — disposable filters (A7038) are typically covered monthly, and reusable filters (A7039) are covered every 6 months, which aligns exactly with the recommended replacement schedules for the ultra-fine filter (30 nights/monthly) and pollen filter (6 months) respectively. Whether a specific patient's plan covers these items depends on their diagnosis, the plan's CPAP supply benefit, and the DME supplier's enrollment with that plan.
