Bosch is a brand known for a wide range of home electronic devices, while Levoit primarily focuses on air purifiers.
Still, both brands produce outstanding products. In this comparison, I’ll take a closer look at two compact air purifiers from these brands: the Bosch Air 2000 and the Levoit Core 300S.
The Levoit Core 300S has a CADR of 141 CFM (240 mÂł/h), whereas the Bosch Air 2000 has a CADR of 106 CFM (180 mÂł/h).
Both models come with plenty of advanced features, but only the Levoit supports smart app integration.
Our Verdict
After analyzing all the specifications and test results, one thing is clear: the Levoit Core 300S is the better buying option.
In our performance tests, the Core 300S delivered better results. It also offers more features, its replacement filters are easier to find, and they’re less likely to go out of stock—unlike the Bosch replacement filters.
If you have any questions about these two air purifiers, feel free to ask in the comments section below the article.

Performance Test – Comparison
We placed these two air purifiers in our testing rooms to test their performance, ensuring each room matched the recommended coverage for the device being tested.
The Levoit Core 300S is designed for rooms up to 219 sq. ft. (20 m²), while the Bosch Air 2000 is recommended for spaces up to 165 sq. ft. (15 m²).
Particle Removal Tests - Comparison
We placed the Bosch Air 2000 and Levoit Core 300S in two separate tests and measured their performance using the Temtop laser particle meter.
In the first test, performed in a 194 sq. ft. (18 m²) room, the Bosch Air 2000 improved air quality by 93%, while the Levoit Core 300S achieved a 94% improvement.
In a second test in a larger 320 sq. ft. (30 m²) room, the Bosch improved air quality by 89%, whereas the Levoit reached 92%.
Although both purifiers delivered great results, the Levoit Core 300S proved to be the better performer overall.
Noise Level Test – Comparison
Before diving into a detailed noise level comparison, it’s worth noting that both air purifiers offer four fan speeds and include an auto mode.
When it comes to noise output at all speeds, the Bosch Air 2000 is generally the quieter of the two.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Bosch Air 2000 and Levoit Core 300S air purifiers.
At the lowest speed, the Bosch produces just 40.1 dBA, compared to 41.4 dBA from the Levoit Core 300S.
At the highest speed, the Bosch reaches 62.7 dBA, while the Levoit peaks at 65.2 dBA.
| Fan Speed | Bosch Air 2000 (dBA) | Levoit Core 300S (dBA) |
|---|---|---|
| Sleep Mode | 40.1 dBA | 41.4 dBA |
| Speed 1 (Low) | 41.6 dBA | 46.5 dBA |
| Speed 2 (Medium) | 51.9 dBA | 54.6 dBA |
| Speed 3 (High) | 62.7 dBA | 65.2 dBA |
Overall, as previously mentioned, the Bosch Air 2000 is slightly better optimized for quieter operation than the Levoit Core 300S.
Operating Costs – Comparison
When it comes to power consumption, both air purifiers are equipped with well-optimized motors.
The Bosch Air 2000 uses just 20W, while the Levoit Core 300S uses a slightly more powerful 26W motor.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Bosch Air 2000 and Levoit Core 300S air purifiers at all fan speeds.
If operated continuously at maximum speed, 24 hours a day for a full month, the Levoit Core 300S would add approximately $2.01 to your electricity bill, compared to about $1.73 for the Bosch Air 2000.
| Fan Speed | Bosch Air 2000 (W + $/month) | Levoit Core 300S (W + $/month) |
|---|---|---|
| Standby | 0.1W ($0.01) | 1.1W ($0.09) |
| Sleep Mode | 2.1W ($0.18) | 3.8W ($0.33) |
| Speed 1 (Low) | 5.3W ($0.46) | 6W ($0.52) |
| Speed 2 (Medium) | 9W ($0.79) | 10.4W ($0.91) |
| Speed 3 (High) | 19.7W ($1.73) | 23W ($2.01) |
While the Bosch is indeed more energy-efficient, there’s a catch when it comes to filter replacements. Many users report difficulty finding Bosch replacement filters, which is why I consider the Levoit Core 300S slightly more affordable and convenient in terms of long-term maintenance.
