In today’s article, I will compare two small, powerful, and reliable air purifiers. The first is the Levoit Core 300, which is one of the best air purifiers I have ever tried. Its competitor is the TruSens Z-1000, a well-built and high-quality air purifier.
These small air purifiers don’t have too many advanced options and cover almost identical rooms. The Levoit Core 300 covers rooms of up to 219 sq. ft. (20 m²), while the TruSens Z-1000 covers rooms of up to 88 sq. ft. (8.2 m²).
What makes these two a great choice are their amazing performance, good price, and affordable and high-quality filters. They both use a three-stage filtration technology but have a few significant differences. Levoit has a True HEPA filter, while TruSens doesn’t. However, TruSens features a UV-C light as a third filtration stage.
Our Verdict
If you look closely at the specifications table below, you will probably notice that the Levoit has better overall characteristics. It performed slightly better in performance tests and is also a quieter air purifier.
This, combined with more features, more affordable filters, a True HEPA filter, and a pellet-based carbon filter, is more than enough to declare the Levoit Core 300 as a better buying option than the TruSens Z-1000.
I hope you enjoyed this brief comparison and that you found answers to all the questions you might have had. However, if you have any additional questions, feel free to ask in the comment section below the article.

Particle Removal Test – Comparison
Regarding the performance tests, things were interesting, and the test results were quite surprising.
We tested these two air purifiers in two different rooms. In the first test, performed in a room of 194 sq. ft. (18 m²), they both improved the air quality by an incredible 93%. In the second test, performed in a room larger than the recommended size, 320 sq. ft. (30 m²), they also achieved similar results.
Particle Removal Tests - Comparison
We placed the TruSens Z-1000 and Levoit Core 300 in two separate tests and measured their performance using the Temtop laser particle meter.
The Levoit Core 300 improved the air quality by about 92%, while the TruSens Z-1000 improved it by about 91%.
Both air purifiers were operated at their maximum speeds, and the tests lasted for 60 minutes.
Besides these tests, we also evaluated how these two air purifiers perform in everyday real-life situations. The conclusion is that the Levoit Core 300 works much better for neutralizing bad odors, which gives it a slight advantage in overall performance.
Smoke Box Test – Comparison
We placed these two air purifiers in a glass box, filled it with smoke, and measured how long it took them to remove all the smoke.
The Levoit Core 300 was twice as fast in this test, taking 20 seconds to clear the smoke, while the TruSens Z-1000 took 40 seconds.
Honestly, I expected this result, especially because the Levoit uses a larger, higher-quality carbon filter and has larger air intake openings.
Noise Level Test – Comparison
When comparing noise levels, we always measure noise at all speeds and then compare the levels between devices.
The Levoit Core 300 has four fan speeds, while the TruSens Z-1000 has three.
After measuring the sound levels at all speeds, the main conclusion is that the Levoit is somewhat louder at all speeds except for sleep mode, which is only available on the Levoit.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the TruSens Z-1000 and Levoit Core 300 air purifiers.
However, because only the Levoit has a sleep mode, this air purifier is much quieter than the TruSens at the lowest speed. At the lowest speed, the Levoit Core 300 produces a sound level of 40.7 dBA, while the TruSens Z-1000 produces a sound level of 43.8 dBA. Frankly, the noise level difference of 3.1 dBA isn’t small, and it’s certainly noticeable.
If we compare the sound levels at the maximum speeds, the difference favors the TruSens, which produces a sound level of 64.4 dBA, while the Levoit Core 300 produces a sound level of 64.9 dBA.
| Fan Speed | Levoit Core 300 (dBA) | Leitz TruSens Z-1000 (dBA) |
|---|---|---|
| Sleep Mode | 40.7 dBA | - |
| Speed 1 (Low) | 46.4 dBA | 43.8 dBA |
| Speed 2 (Medium) | 52.9 dBA | 51.2 dBA |
| Speed 3 (High) | 64.9 dBA | 64.4 dBA |
Another thing I noticed when using the TruSens is that it produces a strange noise at the maximum speed, which, together with the much louder operation at the lowest speed, makes it generally somewhat louder than the Levoit Core 300.
Operating Costs – Comparison
The first thing I want to point out is that the TruSens Z-1000 has a 40W motor, while the Levoit Core 300 uses a 45W motor.
After testing their power usage at all speeds, we found that the Levoit Core 300 is a slightly larger power consumer at all speeds.
Monthly Power Consumption Cost Comparison
Comparison of monthly power consumption costs for the TruSens Z-1000 and Levoit Core 300 air purifiers at all fan speeds.
At the maximum speed, the Levoit consumes 43.5W, while the TruSens consumes 41.2W. So, if you left these two air purifiers running at the maximum speed, 24 hours daily, for one month, your electric bill would increase by about $3.81 in the case of the Levoit and by about $3.61 in the case of the TruSens.
What’s also amazing about the TruSens Z-1000 is that its filter lasts about 12-15 months, which is much longer than the Levoit Core 300 filter’s lifespan of 6-8 months.
| Fan Speed | Levoit Core 300 (W + $/month) | Leitz TruSens Z-1000 (W + $/month) |
|---|---|---|
| Standby | 0.8W ($0.07) | 0.2W ($0.02) |
| Speed 1 (Low) | 29.4W ($2.58) | 9.4W ($0.82) |
| Speed 2 (Medium) | 31.4W ($2.75) | 18.7W ($1.64) |
| Speed 3 (High) | 43.5W ($3.81) | 41.2W ($3.61) |
Overall, things are more or less clear here, and I can easily declare the TruSens Z-1000 as much more affordable to maintain annually.
