Purification Performance and Coverage Area

To gauge the AirDoctor 1000‘s purification capabilities, we conducted rigorous tests in a medium-sized office room. Before unleashing the purifier, we established baseline air quality measurements. Setting the AD1000 to maximum power, we let it operate for an hour before comparing the post-test data to the baseline.

Starting Baseline

PM2.5: 2.0
PM10: 3.5
Particles: 359
AQI: 8

Aftre 1 Hour

PM2.5: 0.1
PM10: 0.2

Particles: 10

AQI: 1

The air purifier can cycle the air in a 285 sq. ft. area 4 times in 1 hour. According to AirDoctor, the AD1000 can also cover a 570 sq. ft. area by exchanging the air 2 times in 1 hour. It does this with a CADR of 162 CFMs

The AirDoctor 1000 demonstrated an impressive performance, eliminating a remarkable 95.0% of airborne particulates and significantly improving PM2.5 air quality by 97.2%. Precise readings were obtained using the Temtop LKC-1000S+ professional air quality detector.

Below we’ve included information on our testing criteria and what defines good vs. bad air quality. Simply put, the lower the number the better.

The Filters

At the core of the AirDoctor 1000 lies a 4-stage filtration system comprising:

  1. Pre-filter: Capturing larger airborne particles like dirt and hair.
  2. Activated carbon filter: Eradicating odors and VOCs, leaving a breath of fresh air.
  3. HEPA filter: Skillfully capturing particles as small as 0.003 microns, ensuring comprehensive purification.
  4. Optional negative ion generator: Binding negative ions to airborne particles, causing them to adhere to surfaces for later cleaning.

Noise Test

With precision, we examined the noise levels of the AirDoctor 1000 by employing a noise meter placed at approximately 3 feet from the purifier. Running the air purifier on each power setting, we sought to evaluate its acoustic performance.

Our results showed the following decibel levels from each mode.


39.2 dB


39.6 dB


41.4 dB


51.4 dB

Our testing showed the AirDoctor 1000 to have a noise range of 39 – 52 dB.

If noise is a concern while you sleep, the AD1000 should be sufficiently quiet, especially on the lower end.

Usability Tests

The AirDoctor 1000‘s appeal lies in its simplicity and ease of use. Boasting a touch screen panel, timers, and an auto mode, it offers a seamless and hands-off approach to purification. Its compact size allows it to effectively cover a medium-sized area, making it an ideal choice for various room settings.


  • Plug in the power cord.
  • Remove packaging from the filter


  • Set preset timer.
  • Turn on/off negative ion generator.
  • Dim lights.
  • Check filter life.
  • Turn on/off device.
  • Adjust fan speed.
  • Turn on/off auto mode

Additionally, a colored LED ring conveys real-time air quality readings based on internal sensors.

As stated above, there is no app connectivity or remote control for the AirDoctor 1000. That being said, it does have a surprisingly robust touch control on the top of the device.

Via the controls you can:


Routine maintenance for the AirDoctor 1000 aligns with industry standards for air purifiers. Regular filter replacements and occasional sensor cleaning are essential for optimal performance.

The device’s HEPA and carbon filters are replaceable independently and come with recommended replacement intervals.

  • HEPA Filter Replacement: Every 6-12 months.
  • Carbon Filter Replacement: Every 12 months (usage-dependent)
