Today I will compare two very similar air purifiers in terms of specifications.
They have similar dimensions, weight, and room coverage. The Philips 600i has a CADR of 100 CFM (170 m³/h), meaning it covers rooms of up to 156 sq. ft. (14.5 m²).
On the other hand, the Electrolux Flow A3 has a CADR of 106 CFM (180 m³/h), meaning it covers rooms of up to 165 sq. ft. (15.3 m²).
When it comes to features, the Philips 600i works with a smart app but doesn’t have an air quality sensor and auto mode. However, the Electrolux Flow A3 doesn’t work with a smart app but has an air quality sensor and auto mode features.
Keep reading to find out which one performed better in our tests.
Our Verdict
I believe the results are fairly clear here.
Even though these two air purifiers have almost identical CADRs, factors such as better airborne particle removal, superior results in the smoke test, and more smart features are the reasons I choose the Electrolux Flow A3 as the better buying option.
If you have any questions about these two air purifiers, please feel free to leave a comment in the comment section below.

Performance Test – Comparison
As I mentioned at the beginning of the article, these two air purifiers have almost identical CADRs, meaning they cover almost identical room sizes.
Accordingly, we tested them in two rooms of the same size.
In the first test, performed in a 120 sq. ft. (11 m²) room, the Electrolux Flow A3 improved air quality by 93%, while the Philips 600i improved air quality by 91%.
Particle Removal Tests - Comparison
We placed the Philips 600i and Electrolux Flow A3 in two separate tests and measured their performance using the Temtop laser particle meter.
In the second test, this time in a room of 194 sq. ft. (18 m²), they achieved the same result. Both air purifiers improved air quality by 89%.
They worked at their maximum speeds for 60 minutes, and we used the Temtop laser particle counter to measure air quality before and after.
I would say that the Electrolux Flow A3 was slightly better in airborne particle removal tests.
Smoke Box Test – Comparison
Our smoke test confirms that the Electrolux performs better and is more efficient than the Philips.
It removed all the smoke from the glass box in just 25 seconds, while the Philips 600i needed 36 seconds.
This is further evidence that the Electrolux Flow A3 uses superior filtration technology.
Noise Level Test – Comparison
The first thing I want to compare regarding noise levels is the number of fan speeds these two air purifiers have.
The Philips 600i has three fan speeds, while the Electrolux Flow A3 has four fan speeds plus auto mode.
We tested their noise levels at all speeds and compared the results.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Philips 600i and Electrolux Flow A3 air purifiers.
At the lowest speed, the Electrolux Flow A3 produces 40.8 dBA of sound, while the Philips 600i produces 40.3 dBA.
At maximum speed, the Electrolux Flow A3 produces 62.8 dBA of sound, while the Philips 600i produces 57.3 dBA.
Although the Electrolux offers more fan speeds, I would say that the Philips 600i is better optimized for noise control.
Operating Costs – Comparison
Regarding power consumption, the first notable thing is that both units are low-power consumers.
However, the Philips 600i uses a slightly more efficient motor of just 12W. On the other hand, the Electrolux Flow A3 uses a 20W motor.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Philips 600i and Electrolux Flow A3 air purifiers at all fan speeds.
If you use these two air purifiers at their maximum speeds, 24 hours daily, for one month, your electricity bill would increase by about $1.67 for the Electrolux and by about $0.86 for the Philips 600i.
Additionally, there’s the cost of replacement filters, which last about 12 months for both air purifiers.
In summary, after calculating all the power costs and the cost of replacement filters, I would say that the Philips 600i is more affordable for maintenance on an annual basis.
