Lastly, the Shark Neverchange 5 Air Purifier features a unique filter system that combines HEPA and carbon filters. This makes it excellent for capturing both tiny particles and larger odors. It’s designed for long-lasting use, so you won’t have to change the filters often.
Here’s a quick comparison of their filter efficiency:

In contrast, the Blueair Blue Mini Max Air Purifier operates slightly louder at 35 decibels on its lowest setting. While still manageable, it may be more noticeable when you are trying to sleep.
Lastly, the Shark Neverchange 5 Air Purifier has a higher noise level, reaching 45 decibels at low speed. This can be distracting during the night, making it less ideal for light sleepers.
| Product | Noise Level (Low) | Sleep Mode |
|---|---|---|
