How the three filter stages work
Pre-filter
Catches dust, pet hair and larger debris before air reaches the finer filters, as AirDoctor describes it.
Carbon / VOC filter
A carbon stage aimed at cooking, pet and household odors and gases.
UltraHEPA filter
AirDoctor states it captures 99.99% of particles down to 0.003 microns.
Auto mode and sensor
Larger models list an air-quality sensor with an automatic mode that adjusts fan speed, plus a 24-hour timer.
Choose a size by room, not by name
Coverage is the number that matters most for a large or open-plan room. A purifier rated below your room size has to work harder and may not keep up. Use the figures AirDoctor publishes as a starting point, then allow for tall ceilings and open layouts.
Pets and odors: what to expect
Pet homes tend to collect hair, dander-sized particles and odors. A purifier with a pre-filter and a carbon stage addresses those at the air-handling level, but it works alongside regular cleaning, not instead of it. Place the unit where air can move freely around it, away from walls and furniture, and replace filters on the schedule the maker lists.
Running cost and filters
Filters are an ongoing cost. On the 3500, AirDoctor lists carbon/VOC filters every 6 months and UltraHEPA filters every 12 months, with an optional filter subscription that may include a discount and extended warranty. Add the yearly filter cost to the purchase price when you compare models.

Common questions
Does an air purifier help with pet hair?
AirDoctor describes a pre-filter that catches dust, pet hair and larger debris before air reaches the finer filters. A purifier filters airborne particles in a room; it does not replace vacuuming or grooming.
Will it remove cooking or pet odors?
AirDoctor lists a carbon/VOC filter stage aimed at odors and household gases. Results depend on the room, the source of the odor and how the unit is placed.
Which AirDoctor suits a large or open-plan room?
AirDoctor lists coverage per model, from about 305 sq ft up to 1,043 sq ft for the 5500. Choose a model rated at or above your room size, and remember ceiling height and open layouts affect real-world coverage.
How often are filters replaced and what does it cost?
On the 3500, AirDoctor lists carbon/VOC filters every 6 months and UltraHEPA filters every 12 months, with an optional filter subscription. Check the model page for current filter prices.
Is there a money-back guarantee?
AirDoctor states a 30-day money-back guarantee and a 1-year warranty. Read the full terms on the official site before you buy.
Is an air purifier a medical device?
No. It filters air in a room and does not diagnose, treat or prevent any condition. Speak to a healthcare professional about medical concerns.
