Performance Summary

At Modern Castle we test 11 different factors that impact the performance, build quality, and usability of the air purifier. Below is a complete list of our testing categories and their performance.

Test Type	Test Data
PM2.5 (1 hour test)	0.2 ppm
PM10 (1 hour test)	0.2 ppm
Particles (1 hour test)	29
AQI (1 hour test)	1
Ozone Detected	0.0 ppm
Filter Type	HEPA, Carbon, Pre-Filter, Ionizer
Coverage Area	610 sq. ft. (57 sq. m.)
CADR	162 CFM
Max Wind Speed	16.3 mph (26.2 kph)
Noise Test	65.1 dB

To test the purification performance of the AirDoctor 2000i, we placed it in a medium-sized room in our office (~14’ x 10`). Next, we lit incense to introduce smoke and other particulates into the air for 30 seconds. After, we use a professional air quality detector to measure the smoke-filled air.

Next, we run the air purifier on the highest fan speed for 2 hours, taking measurements of the air quality at the one hour mark and the end of the test. Here is what we found:

Performance Metric	Starting Measurement	After 1 Hour	After 2 Hours
PM2.5	65.0 ppm	0.2 ppm	0.1 ppm
PM10	111.8 ppm	0.2 ppm	0.1 ppm
Particles	9609	29	9
AQI	155	1	2

In our air purification tests, the AirDoctor 2000i was able to reduce PM2.5 to 0.2 ppm. This is 0.29 ppm lower than the average of 0.49 ppm, based on all of our air purification tests to date.

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

If we look at the 2-hour measurements, the AirDoctor 2000i further continues to improve the air quality by reducing the PM2.5 to 0.1 ppm.

With most air purifiers ozone generation isn’t an issue. That said, some that use negative ion generators have the potential to create ozone. To test this, we run the AirDoctor 2000i, letting it run for 1 hour, and measure the levels of ozone before and after with an ozone meter device.

In our ozone tests, the AirDoctor 2000i generated no measurable ozone during testing.

The filters are AirDoctor’s own proprietary filters that include 4 different filter types.

Coverage

The AirDoctor 2000i has a coverage area of 610 sq. ft. It is best suited for small to medium-sized rooms.

Comparing the AirDoctor 2000i to the average, it has a smaller coverage than our testing average. Across all air purifiers we’ve tested to date, the average coverage area is 747 sq. ft. and the average CADR is 290 CFM.

Wind Speed Test

Our wind speed test uses an anemometer placed directly on the air vents of the AirDoctor 2000i to measure the fan speeds in miles per hour. We run it on the lowest and highest fan speeds and record the speed of the air coming out of the device.

In our win speed test, the AirDoctor 2000i generated a maximum wind speed of 16.3 mph. This is 3.89 mph lower than the average of 12.41 mph, based on all of our wind speed tests to date.

This is a high wind speed for such a small system. Typically, we see higher fan speeds with the larger air purifiers that have bigger fans. However, there are multiple fan speeds on the AirDoctor 2000i for your preference.

Our build quality test is a subjective test where we examine and assess the major material and design components of the air purifier. Specifically, we are looking for build and design issues that are more likely to break and/or be difficult to use.

The build quality of the AirDoctor 2000i is exceptional when looking at their full line of air purifiers. The plastic is sturdy and does not rattle when handling the machine. They all come with a simple white glossy body that can fit into most decor. Additionally, it’s lightweight enough to be moved by picking it up and not needing to wheel it around.

Part	Build Quality
Overall	Exceptional
Body	Excellent
Fan	Exceptional
Filters	Exceptional
Controls	Exceptional
Display	Excellent
Remote	n/a
Wheels	n/a

When compared to others, it is my view that AirDoctor 2000i feels strong and will last when compared to others of similar size. However, it entirely depends on how the air purifier is treated and the environment it operates in.

To determine the level of noise that the AirDoctor 2000i creates we use a sound meter and measure the decibel levels on both the lowest and highest fan speeds. In addition, we measure the ambient noise levels of the room as a baseline comparison.

In our noise tests, the AirDoctor 2000i generated 65.1 dB of noise on the max fan speed. This is 2.86 dB more than the average of 62.24 dB, based on all of our noise tests to date.

This shocked us while testing the small machine. Typically, smaller form factor machines are quieter, as the motors are usually not as large or loud. However, a nice trade-off for this higher noise is the improved purification performance.

The AirDoctor 2000i is a small, compact air purifier that offers easy setup, high user functionality, and the new AirDoctor control app.

Set up took less than 5 minutes to remove the air purifier from the package and plug it in.

The most important step during setup is to remove the filters and remove the plastic packaging around the filters.

The controls on the AirDoctor 2000i are on the top of the purifier. They are backlit with LEDs to help the user identify the current fan settings.

Wireless Controls

The new AirDoctor app allows for enhanced control and system status information at the user’s fingertips. The app allows the owner to control all features, functionalities, and maintenance alerts for the AirDoctor 2000i. It also displays room air quality and the local air quality / weather.

Product Evolution

The AirDoctor 2000i is an update to the existing AirDoctor 2000. The new “i” distinction indicates the AirPurifier is wifi / app compatible. The AD 2000i is joined by the 3500i and 5500i, which were also older models that are now upgraded with wifi.

In terms of air purification functionality, nothing has changed between the 2000i and 2000 models. The only difference is the addition of wifi compatibility.

How does AirDoctor 2000i compare?

Below is a complete list of our air purifier tests and critical product data compared side by side to the average based on all of our air purifier tests to date.

Test Type	Test Data	Avg. Data
PM2.5 (1 hours)	0.2 ppm	0.49 ppm
PM10 (1 hours)	0.2 ppm	0.74 ppm
Particles (1 hours)	29	61.04
AQI (1 hours)	1	1.91
Ozone Detected	0.0 ppm	0.0 ppm
Filter Types	HEPA, Carbon, Pre-Filter, Ionizer	n/a
Coverage Area	610 sq. ft.	744 sq. ft.
CADR	162 CFM	291 CFM
Max Wind Speed	16.3 mph	12.4 mph
Noise Test	65.1 dB	62.2 dB

Most notable is the purification performance for this smaller unit compared to larger systems. The PM2.5, PM10, AQI, and Number of Particles measured after the first hour are exceptional. Typically we see larger / more powerful air purifiers improve the air quality to these levels.
