The Jerdazen JZ450 Air Purifier is the bigger, more powerful sibling of the JZ200, designed for those who need air purification in larger spaces. The JZ450 shares a lot of similarities with the smaller version and it is expected to deliver the same impressive performance.

Design and Ease of Use
The JZ450 is easy to set up and operate, making it user-friendly right out of the box. The design leans towards a modern aesthetic, with an intuitive touch control panel on top. It has 8 touch-sensitive buttons, including on/off, timer, fan speed, auto mode, sleep mode, and light controls. There’s also a lock button, which prevents accidental presses—perfect for households with children. The timer allows you to set the purifier to run for 2, 4, or 8 hours, while the auto mode adjusts the fan speed based on the current air quality. The display features an air quality index reading and provides a PM2.5 reading. The air quality is visually indicated by a colored ring around the purifier’s middle: green for good air quality, yellow for moderate, and red for poor. This real-time feedback is helpful for monitoring indoor air quality.
Filtration and Performance
At the core of the JZ450 is the 3-stage filtration system consisted of a pre-filter, a True HEPA filter, and an activated carbon filter. The HEPA filter can capture up to 99.97% of airborne particles as small as 0.1 to 0.3 microns. This includes dust, pollen, smoke, and other allergens, making it highly effective for improving indoor air quality. The air purifier can handle spaces up to 2,200 square feet, which is more than adequate for most homes or large rooms.
The fan on this purifier is powerful, especially at higher speeds, where it really pulls in a lot of air, which is excellent for filtering efficiency. It’s relatively quiet on lower settings, but if the air quality gets worse – like when I start cooking or if there’s smoke nearby – the auto mode will kick the fan into high gear, the noise becomes noticeable, and the room felt noticeably fresher within minutes. I appreciate that it’s doing its job by cleaning the air, and if you don’t like the increased noise, you can manually lower the fan speed.
The air purifier requires regular filter replacements – typically every 6 to 12 months, depending on usage. This could become a significant financial burden over time as a filter costs $46.99 at this time on Amazon.
Conclusion
Pros:
- High-performance HEPA filtration
- Auto mode effectively adjusts to changing air quality levels
- Sleek design
- Large coverage area up to 2,200 square feet
- Real-time air quality display with color-coded indicators.
Cons:
- Replacement filters are expensive
- No washable pre-filter to extend filter life
The Jerdazen JZ450 is an excellent air purifier when it comes to performance and design. It effectively cleans the air, is easy to use, and there is no complicated smart features. If the filter’s price comes down a bit, this would be an easy recommendation from us.
