*The new AirDoctor 4000 is now available on pre-sale at a special introductory price for a limited time. Shipping is expected to begin in mid-October.

Keep your AirDoctor 4000 performing as intended with a genuine replacement filter made specifically for the unit.

The AirDoctor 4000 3-in-1 Filter combines the Pre-Filter, Premium Carbon/Gas Trap/VOC layer and UltraHEPA® filter in one replacement. Together, the three stages capture larger household particles, help reduce gases and odours, and filter ultra-fine airborne particles as small as 0.003 microns.

There are no separate filters to replace individually. When the time comes, one new filter refreshes all three filtration stages at once. Replacement is recommended approximately every six months for consistent performance.

Three stages in one easy change

Everything the AirDoctor 4000 needs for filtration is brought together in a single replacement filter.

The Pre-Filter catches larger particles such as dust, lint and pet hair before they travel further into the filter. The Premium Carbon/Gas Trap/VOC layer helps reduce household odours, gases and VOCs. The independently tested UltraHEPA® filter captures 99.99% of airborne particles as small as 0.003 microns, including allergens, mould spores, smoke, bacteria and viruses.

Because all three stages are replaced together, there are no different filters or replacement schedules to keep track of. Simply replace the complete filter when needed and your AirDoctor 4000 is ready to carry on.

Knowing when it is time for a new filter

As a general guide, the AirDoctor 4000 filter should be replaced approximately every six months. Filter life can vary depending on how often your purifier runs and the air quality in your home, so the filter indicator on the control panel will let you know when a change is due.

When fitting the replacement, wipe the exterior and Pre-Filter area with a soft, dry cloth to clear away built-up dust. If your home has particularly high levels of dust or smoke, you may find that the filter needs replacing sooner.

Keeping up with filter changes helps maintain efficient airflow and consistent filtration performance over time.
