Philips and Blueair are well-known global air purifier brands. In this article, I will compare two small air purifiers from these brands: the Blueair 411 Auto, an updated and improved version of the Blueair 411, and the Philips Series 800, a unique and innovative air purifier.
There isn’t a significant difference in room coverage between these two models. The Blueair 411 Auto covers rooms up to 190 sq. ft. (18 m²), while the Philips Series 800 is suitable for rooms up to 176 sq. ft. (16 m²).
Performance test results for both purifiers are nearly identical, as are their noise levels. However, the Blueair produces a slightly clunky sound at its third speed, leading me to rate its noise levels lower than the Philips.
Regarding power consumption, the Blueair 411 Auto is more energy-efficient, but the Philips Series 800 isn’t a huge consumer either.
Both air purifiers share features like an air quality sensor, air quality indicator, and auto mode. While they lack smart apps or other advanced features, the auto mode is a great way to automate these air purifiers.
When it comes to build quality, I have a slight preference for the Philips’s plastic and overall build quality, as the Blueair appears more fragile. However, the modern, minimalist design of both air purifiers is appealing.
Our Verdict
While the Blueair 411 Auto and Philips Series 800 share many similarities, making the comparison challenging, the Blueair 411 Auto is the winner in this comparison and is my recommendation.
Although the Philips Series 800 performed better in noise tests, the Blueair offers slightly superior overall performance, lower maintenance costs, faster results in our smoke test, and a washable pre-filter.
Neither device uses a True HEPA filter. The Philips features a pellet-based carbon filter, whereas the Blueair utilizes an innovative pre-filter and HEPASilent technology.

Performance Test – Comparison
These are two very small air purifiers with low CADR and room coverage.
The Blueair 411 Auto covers rooms up to 190 sq. ft. (18 m²), while the Philips Series 800 covers rooms up to 176 sq. ft. (16 m²). Both devices will clean the air 4.8 times per hour in their recommended room sizes.
We tested them in two different rooms based on their coverage. In the first test, performed in a 194 sq. ft. (18 m²) room, the Blueair 411 Auto improved the air quality by 94%, while the Philips Series 800 improved it by 93%.
Particle Removal Tests - Comparison
We placed the Blueair 411 Auto Vs Philips Series 800 in two separate tests and measured their performance using the Temtop laser particle meter.
However, in the second test, both devices improved the air quality by 91%. This test was performed in a 320 sq. ft. (30 m²) room.
In both tests, the devices operated at their maximum speeds, and each test lasted 60 minutes.
Although the results in the particle removal tests were almost identical, I must say that the Blueair 411 Auto performed slightly better, and I would pick it as the winner in this comparison.
Smoke Box Test – Comparison
In our smoke test, both air purifiers performed quite well. The Blueair 411 Auto managed to remove all the smoke from the glass box in just 27 seconds, while the Philips took 33 seconds.
Considering that the Blueair has a slightly higher CADR of 123 CFM (210 m³/h), I expected it to be a bit faster in this test.
Overall, these results aren’t as impressive as those achieved by the Levoit Core 300S, which completed the test in 20 seconds, but they still performed very well.
