Philips is one of the most popular manufacturers of air purifiers on the market, and I believe I haven’t given this brand the attention it deserves.
For that reason, I recently purchased several models from Philips, which I plan to test and review over the coming months.
In this article, I will compare the Philips 600i Series and the Philips 800 Series—two compact air purifiers with some notable differences.
The Philips 600i is slightly smaller, designed to cover rooms up to 156 sq. ft. (14.5 m²), while the Philips 800 can cover spaces up to 176 sq. ft. (16 m²).
The Philips 800 features an air quality sensor, an air quality indicator, and an auto mode, whereas the Philips 600i works with the Philips Air+ smart app.
Our Verdict
Overall, the Philips 800 is a superior air purifier in many respects. The only advantage of the Philips 600i is its ability to connect with the Philips Air+ smart app.
However, the Philips 800 outperforms the 600i with better overall performance, more advanced features, a higher CADR, and a higher-quality filter, making it the better buying option in this comparison.
In my opinion, the Philips 800 would be even more appealing if it offered compatibility with the Philips Air+ smart app. However, this isn’t something that would significantly impact my recommendation.
If you have any questions about these two Philips models, feel free to leave a comment below the article.

Performance Test – Comparison
Before diving into a detailed comparison of the performance of these two models, I would like to start by comparing their CADR values.
The Philips 600i has a CADR of 100 CFM (170 m³/h), making it suitable for rooms up to 156 sq. ft. (14.5 m²). In contrast, the Philips 800 has a CADR of 112 CFM (190 m³/h), making it ideal for rooms up to 176 sq. ft. (16 m²).
To evaluate their real-world performance, we tested both devices in several rooms of different sizes. But, the most important test for this comparison was conducted in a 194 sq. ft. (18 m²) room.
Particle Removal Tests - Comparison
We placed the Philips 600i Vs Philips 800 in two separate tests and measured their performance using the Temtop laser particle meter.
In this room, after 60 minutes of operation at maximum speed, the Philips 800 reduced PM2.5 particulate matter from 93 to 6.5 µg/m³, resulting in an overall air quality improvement of approximately 93%.
Under the same conditions, the Philips 600i achieved an air quality improvement of around 89%.
These results clearly show that the Philips 800 outperformed the Philips 600i thanks to its higher-quality filter and superior CADR.
Noise Level Test – Comparison
Both air purifiers have a small number of fan speeds, especially the Philips 800 Series, which has only two fan speeds plus an auto mode.
For this reason, I compared the noise levels produced by these two models at their lowest and maximum speeds.
Noise Level Comparison
Comparing the Philips 600i Vs Philips 800 noise levels at minimum and maximum speeds.
At the lowest speed, the Philips 800 produces a noise level of 41.8 dBA, while the Philips 600i produces 40.3 dBA.
However, at maximum speed, the difference is even larger. The Philips 800 produces a noise level of 62.8 dBA, whereas the Philips 600i is noticeably quieter, measuring just 57.3 dBA.
Overall, while both devices are well-optimized for noise reduction, I would say the Philips 600i has a slight edge. This is primarily because it operates more quietly at all compared speeds and offers an additional fan speed option compared to the Philips 800.
Operating Costs – Comparison
These are two highly efficient air purifiers, featuring some of the best motors on the market when it comes to the power-to-CADR ratio.
The Philips 600i is equipped with a 12W motor, while the Philips 800 has a slightly more powerful 20W motor.
If you were to operate these devices at maximum speed, 24 hours a day, for an entire month, your electricity bill would increase by approximately $1.53 for the Philips 800 and around $0.86 for the Philips 600i.
Power Usage Comparison
Comparing the Philips 600i Vs Philips 800 power use at minimum and maximum speeds.
It’s worth noting, however, that the Philips 800 also delivers a slightly higher CADR.
In addition to electricity costs, you should also consider the cost of replacement filters, which need to be changed approximately once a year for both devices.
That said, due to the higher price of replacement filters and the slightly higher electricity consumption, the Philips 800 is somewhat more expensive to maintain on an annual basis.
