Pura 3 vs Pura 4: Detailed Comparison and Recommendations
Smart home fragrance has taken a big step forward with Pura’s lineup of diffusers.
Today, I’m looking at the Pura 3 and Pura 4 models. Since choosing the right diffuser matters for your home and budget, I’ll share my experience with both devices.
While the Pura 3 has proven reliable over time, the Pura 4 offers new features.
If you’re considering adding controlled scents to your home, understanding the differences between these two models will help you make the right choice for your needs.
Overview of Pura 3
The Pura 3 stands out with its practical design and trusted performance. The unit includes essential features like a built-in nightlight and a larger lighting area.
The device has a twist mechanism that properly positions your scent cartridges to prevent leaking.
Setting up the Pura 3 involves a hands-on approach. You’ll need to scan barcodes for each fragrance you insert, which helps the device know which scents you’re using.
The unit accepts two fragrance cartridges simultaneously, letting you switch between different scents throughout your day.
Regarding build quality, the Pura 3 is slightly bigger than its newer counterpart but maintains a clean look that fits well in most spaces.
One button on the device serves as a reset option, which is handy if you need to troubleshoot any connection issues.
From my testing, the Pura 3 reliably follows your set schedules, though it won’t alert you when fragrances run low—you’ll need to check levels yourself.
While it lacks newer features, many users appreciate its consistent performance and proven track record.
The Pura 3 is cheaper than the Pura 4, making it an attractive option for those starting with smart fragrance systems.
Overview of Pura 4
The Pura 4 brings significant improvements to smart home fragrance.
The most notable addition is its automatic fragrance recognition – when you insert a scent cartridge, the device instantly identifies it without any scanning.
Another smart feature is its ability to monitor fragrance levels and notify you before they run out.
In terms of design, the Pura 4 is more compact than the Pura 3, making it less noticeable on your wall.
The unit maintains the essential twist-top mechanism for secure cartridge placement and includes a built-in nightlight, though it is smaller than its predecessor.
One of the Pura 4’s standout features is its smart adjusting technology that changes diffusion based on your room’s temperature and humidity.
My experience shows it maintains consistent scent levels despite environmental changes. Like the Pura 3, it holds two fragrances and lets you control schedules through the app.
The device gets regular firmware and software updates, suggesting more features may come.
While the Pura 4 costs more than the Pura 3, its added features and smaller footprint make it worth considering.
The smell typically fades within 20-30 minutes after the device stops running, giving you precise control over your home’s fragrance.
