## Cons
- Odor Control Issues: Lacks a carbon pre-filter, leading to poor odor control, especially near litter boxes and for household odors.
- Frequent Filter Alerts: The filter replacement alerts can be frequent, sometimes occurring after only six months, and maintenance can be costly.
- Inaccurate Air Quality Readings: Air quality readings are often triggered by humidity rather than actual dust or debris, leading to unreliable monitoring.
- Performance Compared to Competitors: Some reviews state that a Honeywell unit outperforms it, especially in odor elimination, questioning the efficacy of its odor control.
- Connectivity Problems: The mobile app controls suffer from impracticality and frequent connectivity issues, detracting from the smart functionality appeal.
- Design Limitations: The carbon filter layer is inadequate and non-removable, reducing its effectiveness over time compared to the HEPA filter.
- Ineffective for Odors: Does not perform well in eliminating cooking particles and odors, often spreading them around the house instead.
- High Maintenance with Pets: Pet hair can clog the intake, making maintenance cumbersome and more complex than expected.

## Bottom Line

The Levoit PlasmaPro 400s Smart 403 Sq. Ft True HEPA Air Purifier is perfect for those who prioritize air quality improvements and smart home integration, notably in pet-friendly households. While it boasts an impressive air purification system and seamless design, odor control and reliability issues could be a drawback, especially for pet owners. If odor elimination is a particular concern, you might consider exploring alternative options, such as those from Honeywell or other brands that offer specialized carbon filtration solutions.
