Levoit produces some of the best air purifiers on the market, while Bosch is a premium home electronics brand with many product categories, including air purifiers.
These are two small air purifiers: the Levoit has a CADR of 141 CFM (240 mÂł/h), while the Bosch has a CADR of 106 CFM (180 mÂł/h).
The Bosch Air 2000 has a cylindrical design, while the Levoit Vital 100S is rectangular.
Both use three-stage filtration, but the Levoit includes a washable pre-filter, making it easier to clean and maintain.
Our Verdict
After analyzing all the specifications, test results, and other relevant factors, I chose the Levoit Vital 100S as the winner.
It offers a higher CADR, better performance, a washable pre-filter, always available replacement filters, and plenty of smart features.

Performance Test – Comparison
What I truly like is when two air purifiers have the same or very similar room coverage.
In this case, the Levoit Vital 100S is rated for rooms up to 219 sq. ft. (20 m²), while the Bosch Air 2000 covers rooms up to 165 sq. ft. (15 m²).
We tested both devices in rooms of the same size and compared the results. 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 Vital 100S achieved a 95% improvement.
Particle Removal Tests - Comparison
We placed the Bosch Air 2000 and Levoit Vital 100S in two separate tests and measured their performance using the Temtop laser particle meter.
In the second test, performed in a larger 320 sq. ft. (30 m²) room, the Levoit Vital 100S improved air quality by 94%, while the Bosch Air 2000 reached 89%.
Overall, the Levoit Vital 100S performed better in our airborne particle removal tests.
Noise Level Test – Comparison
The Bosch Air 2000 has four fan speeds, while the Levoit Vital 100S has five.
We measured noise levels at each speed using a specialized noise meter and found no significant differences overall.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Bosch Air 2000 and Levoit Vital 100S air purifiers.
At the lowest speed, the Levoit Vital 100S produces 40.5 dBA, while the Bosch Air 2000 produces 40.1 dBA.
At maximum speed, the Levoit Vital 100S reaches 65.4 dBA, whereas the Bosch Air 2000 measures 62.7 dBA.
| Fan Speed | Bosch Air 2000 (dBA) | Levoit Vital 100S (dBA) |
|---|---|---|
| Sleep Mode | 40.1 dBA | 40.5 dBA |
| Speed 1 (Low) | 41.6 dBA | 42.7 dBA |
| Speed 2 (Medium) | 51.9 dBA | 51.6 dBA |
| Speed 3 (High) | 62.7 dBA | 58.7 dBA |
| Speed 4 (Turbo) | - | 65.4 dBA |
Overall, despite having fewer fan speeds and a lower CADR, the Bosch Air 2000 appears slightly better optimized for noise.
Operating Costs – Comparison
As for power consumption, the Bosch uses a 20W motor, while the Levoit uses a 35W motor, which is more powerful but not significantly so.
If you were to run both air purifiers at maximum speed, 24 hours a day for one month, your electricity bill would increase by about $2.66 with the Levoit and about $1.73 with the Bosch.
However, replacement filter costs also matter. Filters for the Levoit are not only cheaper but also easier to find.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Bosch Air 2000 and Levoit Vital 100S air purifiers at all fan speeds.
I’ve noticed several times that Bosch Air 2000 replacement filters are out of stock, and there are no third-party alternatives available if the official filters aren’t.
| Fan Speed | Bosch Air 2000 (W + $/month) | Levoit Vital 100S (W + $/month) |
|---|---|---|
| Standby | 0.1W ($0.01) | 1.5W ($0.13) |
| Sleep Mode | 2.1W ($0.18) | 3.2W ($0.28) |
| Speed 1 (Low) | 5.3W ($0.46) | 6.5W ($0.57) |
| Speed 2 (Medium) | 9W ($0.79) | 10.5W ($0.92) |
| Speed 3 (High) | 19.7W ($1.73) | 17.6W ($1.54) |
| Speed 4 (Turbo) | - | 30.3W ($2.66) |
For this reason, even with slightly higher power consumption, I would choose the Levoit Vital 100S as the more affordable option in the long run.
