AirDoctor 3000 Review

Written By: Dr Fahad Yasin


The AD3000 is a medium sized air purifier from AirDoctor. It covers 628 sq. ft. with 4 different filters. In our tests, the AirDoctor 3000 successfully improved PM2.5 by 97.0% and reduced airborne particulates from 493 to 15. It isn’t the quietest air purifier and it lacks app connectivity, but it is incredibly easy to use. Setup is simple, the controls are intuitive, and maintenance needs to be done rarely. It is a bit pricey, but the performance speaks for itself.

The AirDoctor 3000 is a medium sized, basic air purifier.. It lacks app connectivity or remote control.. But, the AD300 makes up for it in simplicity and performance. It reduced PM2.5 to 0.1 and removed 95.2% of airborne particulates. Setup is quick, while controlling and maintaining the device was straightforward. For the coverage area it is pricey, but if you want assurance the air is clean, the AirDoctor 3000 is a solid choice.

Purification Performance

To test the AirDoctor 3000, we set up the air purifier in a medium sized room in our office. I took a baseline measurement before starting the test to measure the current air quality. Then, I let the AirDoctor 3000 run on the highest setting for 1 hour and measured the air quality to get another set of measurements.

Starting Baseline

PM2.5: 2.1

PM10: 3.5

Particles: 493

AQI: 8

After 1 hour

PM2.5: 0.1

PM10: 0.2

Particles: 15

AQI: 1

Within the 1 hour test, the AirDoctor 3000 removed 95.2% of air particulates from the medium-sized room we tested in (~14’x10’).

The AirDoctor 3000 improved PM2.5 air quality by 97.0%

In order to get these measurements, we used the Temtop LKC-1000S+ professional air quality detector. This device allows us to get precise readings and performance metrics before and after the test.
Below, we’ve included information on the testing criteria and what defines good vs. bad air quality.

The Filters

To achieve this filtration performance, the AD3000 uses 4 different filters in tandem.

AirDoctor uses similar filters in all of their air purifiers. The pre-filter catches larger particles like hair floating around in the air.

Next, the carbon filter absorbs VOC’s and other odors removing them from the air. 

The main filter, the HEPA filter, catches the majority of the airborne particulates as small as 0.003 microns. 

Finally, the negative ion generator will attach negative ions to particulate matter in the air. Once attached, it will cause them to stick to a surface to be wiped up later. 

Noise Test

Our noise test measures the level of noise generated by the AirDoctor 3000 while it is running. We run it on each power mode, stand about 3’ away, and measure the amount of noise generated with a sound meter app.

Our results showed the following decibel levels from each mode


41.3 dB


44.2 dB


43.4 dB


53.1 dB

Overall, the noise level of the AD3000 fell between 41 – 54 dB. It isn’t the quietest air purifier we’ve tested, which could be an issue for those who like it quiet during the night.

Still, at its quietest, the noise level is similar to a babbling brook and can be a soothing white noise for some.

Usability Tests

Usability for the AirDoctor 3000 was good overall. It was incredibly easy to set up, use, and maintain.

It lacks app connectivity or remote control features, but what it lacks in features it makes up for in ease and performance.


Setup is incredibly simple for the AD3000 as it effectively comes set up out of the box. All you need to do is remove the packaging from around the filter inside and plug the device in.

From there the air purifier is ready to run and clean the air.


As mentioned previously, there is no app connectivity or remote control with the AirDoctor 3000. Instead, there are only physical touch buttons to control the device.

These buttons allow you to:

While these buttons are simple, they are touch sensitive and easy to use.


Maintenance, like all other usability subcategories, is straightforward and easy. You will need to replace the filters as they wear out and wipe down sensors over time.
HEPA filters should be replaced every 6-12 months depending on usage and environment. Whereas carbon filters should be replaced every 12 months.

Size & Dimensions

The AirDoctor 3000 is a medium sized air purifier. It’s lightweight and easy to carry around, thanks to handles, which were thoughtfully included by the manufacturer.

Here are the exact dimensions of the AirDoctor AD3000:

The AD3000 can cover 628 sq. ft. with a CADR of 373 CFMs. This is enough coverage for any medium sized room and some larger ones.
