Performance Testing: AirDoctor 3000 Excels in Speed
Matching CADR Claims with Real-World Particle Removal Efficiency
At HouseFresh, we prioritize empirical testing over manufacturer claims. Having encountered instances of overstated marketing, we conduct independent performance tests to objectively assess air purifier effectiveness in particle removal.
AirDoctor AD3500 air cleaning performance test setup
We utilize the PurpleAir PA-I Indoor sensor, a highly accurate device for real-time PM1, PM2.5, and PM10 particle monitoring. Our test methodology involves filling a 728 cubic feet test room with incense smoke and measuring the time required for the air purifier to reduce PM1 levels to zero. This standardized test allows for direct performance comparisons across different air purifier models.
Air Purification Test Results
Testing the AirDoctor 3000 at its highest speed with the ionizer activated, it achieved a zero count for PM1.0 and PM2.5 particles in just 14 minutes. Consistent results were obtained in repeat tests, confirming its rapid purification capability.
This performance is notably faster than the Levoit Core 600S and the industrial-grade AlorAir CleanShield HEPA 550 Air Scrubber.
Initial tests included the ionizer function. While older ionizer technologies have raised ozone concerns, modern implementations, like in the AirDoctor 3000, generally minimize ozone emission. Our ozone detector recorded levels between 0 PPM and 0.1 PPM during extended operation with the ionizer, well within safety limits. However, for ozone-sensitive individuals, the AirDoctor 3000 offers the option to deactivate the ionizer. Testing without the ionizer resulted in a slightly slower but still impressive cleaning time of 16 minutes to remove PM1 particles.
We also evaluated low-speed performance, relevant for nighttime or quiet operation. Even at its lowest fan speed (40.2 dB), the AirDoctor 3000 effectively cleaned the test room in 35 minutes, comparable to the Mila air purifier at its highest setting. This demonstrates the AirDoctor 3000’s ability to maintain effective air purification even at quieter, energy-efficient settings.
Comparative Air Cleaning Performance
While slightly slower than the Smart Air Blast Mini, which completed the test in 12 minutes, the AirDoctor 3000 ranks as one of the fastest air purifiers we’ve tested, securing its position as the second-fastest unit in our evaluations.
Noise Level Analysis
Using a sound meter at a 3-foot distance, we measured the noise output at each fan speed:
- Speed 1: 40.2 dB
- Speed 2: 50.5 dB
- Speed 3: 58.2 dB
- Speed 4: 63.6 dB
