The Winix 5510 is a new model on the market and a successor to the popular 5500-2, making it a direct competitor to many air purifiers we’ve tested.
In this article, I’ll thoroughly compare the Winix 5510 and the Levoit Core 400S to help you determine which one is the better choice.
In my opinion, both devices are high-quality, highly efficient, and excellent buying options. But if you’re still uncertain, this is exactly the comparison you need.
If you’ve been following the air purifier market, you probably already know that most Levoit models work with the VeSync app. What’s interesting is that the Winix 5510 also supports a smart app, making it an even stronger competitor to Levoit.
Our Verdict
Although the Levoit Core 400S is one of the best air purifiers I’ve had the chance to use—and it’s often featured in our recommendations—I believe Winix did an excellent job with the 5510 model, which, I think, offers more overall.
What makes the Winix 5510 a better choice than the Levoit is its True HEPA filter, better carbon filter, washable pre-filter, PlasmaWave technology, outstanding performance, quiet operation at lower speeds, and high CADR.

Performance Test – Comparison
Before diving into a detailed performance analysis, I want to note that the Winix 5510 has a CADR of 253 CFM (430 m³/h), making it ideal for rooms up to 392 sq. ft. (36 m²).
In comparison, the Levoit Core 400S is slightly more powerful, with a CADR of 260 CFM (442 m³/h), suitable for rooms up to 403 sq. ft. (37 m²).
Both devices will clean the air in their recommended room sizes approximately 4.8 times per hour.
Particle Removal Tests - Comparison
We placed the Levoit Core 400S and Winix 5510 in two separate tests and measured their performance using the Temtop laser particle meter.
Based on their CADR ratings and recommended coverage, we tested both models in a 320 sq. ft. (30 m²) room.
In just 60 minutes of operation at maximum speed, both the Levoit and the Winix delivered excellent results—each improving air quality by around 96%.
Noise Level Test – Comparison
When it comes to noise levels, something that makes me happy and definitely makes this comparison easier is that both devices have five fan speeds.
We measured noise levels at each speed and compared the results, which you can see in detail in the chart below.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Levoit Core 400S and Winix 5510 air purifiers.
What stands out is that the Levoit Core 400S is louder at every speed—except the highest. At maximum speed, the Levoit produces 59.9 dBA, while the Winix 5510 reaches 65.7 dBA.
At the lowest speed, the Winix operates at 40.2 dBA, whereas the Levoit registers 42.1 dBA.
| Fan Speed | Winix 5510 (dBA) | Levoit Core 400S (dBA) |
|---|---|---|
| Sleep Mode | 40.2 dBA | 42.1 dBA |
| Speed 1 (Low) | 41.5 dBA | 43.6 dBA |
| Speed 2 (Medium) | 43.2 dBA | 47.8 dBA |
| Speed 3 (High) | 52.7 dBA | 55.4 dBA |
| Speed 4 (Turbo) | 65.7 dBA | 59.9 dBA |
Overall, I’d say the Winix is slightly better optimized for noise, though the Levoit offers a better noise-to-CADR ratio at its highest setting.
Operating Costs – Comparison
Similar to the noise level test, the Levoit Core 400S is noticeably better optimized at maximum speed, primarily because it uses a more efficient 38W motor.
In contrast, the Winix 5510 is powered by a 65W motor.
This means that if you were to run both devices at maximum speed, 24 hours a day for a month, your electricity bill would increase by approximately $4.68 with the Winix and about $3.06 with the Levoit.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Levoit Core 400S and Winix 5510 air purifiers at all fan speeds.
Additionally, both devices require replacement filters roughly once a year.
| Fan Speed | Winix 5510 (W + $/month) | Levoit Core 400S (W + $/month) |
|---|---|---|
| Standby | 1.1W ($0.01) | 0.9W ($0.07) |
| Sleep Mode | 3.7W ($0.32) | 3.3W ($0.28) |
| Speed 1 (Low) | 4.1W ($0.36) | 5.8W ($0.5) |
| Speed 2 (Medium) | 7.2W ($0.63) | 8.8W ($0.77) |
| Speed 3 (High) | 16.3W ($1.43) | 16.1W ($1.41) |
| Speed 4 (Turbo) | 53.4W ($4.68) | 35W ($3.06) |
Considering that the Levoit Core 400S has more affordable replacement filters and a significantly more efficient motor, it’s easy to conclude that it is notably more cost-effective to maintain on a yearly basis.
