Dyson Purifier Big+Quiet Formaldehyde: A Comprehensive Review
The Dyson Purifier Big+Quiet Formaldehyde may not have stood out at first glance, but after just one day of using it in my own home, I am convinced that it is an essential appliance. Despite its large and bulky appearance, this purifier fan offers a unique design and functionality. It is important to note that the Big+Quiet Formaldehyde should not be confused with the HEPA Big+Quiet, which is specifically designed for commercial spaces.
As the name suggests, the Dyson Purifier Big+Quiet Formaldehyde is both big and quiet. It has been designed to circulate clean air in large rooms while being placed in a corner, rather than in the center of the space. Dyson claims that it can effectively service spaces up to 100sqm / 1,000sqft in size, projecting filtered air up to 10m. Additionally, the angle of the propelled air can be adjusted, making it a powerful fan as well. Even at full power, it operates at a noise level of no more than 56dB.
Dyson has implemented cone aerodynamics to enhance the Coanda effect, which is used in their other purifiers. According to Dyson, this allows the Big+Quiet to process up to 87 liters of air per second. While it is difficult to measure this metric precisely, I trust Dyson’s claim, as I experienced the powerful air circulation firsthand.
It is worth mentioning that there are two models of the Big+Quiet Formaldehyde, distinguished by their color schemes. The Dyson-exclusive model, which I reviewed, is more expensive but includes an additional CO2 sensor and a second filter. I found the CO2 sensor to be particularly useful, as it helps monitor the ventilation needs of your home. I was alarmed at how quickly CO2 levels can rise in a closed space and the potential negative effects on health. The Big+Quiet can adjust its fan speed dynamically to circulate stale air, but it also serves as an indicator to open doors or windows when CO2 levels become high.
Both models of the Big+Quiet come equipped with several sensors that detect common pollutants, such as dust, pet dander, pollen, formaldehyde emitted from household products, NO2 from car fumes, and VOCs from aerosol sprays. These pollutants are filtered using a HEPA filter that meets the highest H-13 standard. Dyson claims that the filter used in the Big+Quiet Formaldehyde can capture up to 99.95% of air particles as small as 0.1 microns. Additionally, Dyson ensures that the filter can last up to five years.
The purifier features a small onboard display that provides real-time metrics of the different pollutants being filtered. These metrics can also be viewed through the MyDyson app when connected to your phone. The app also allows for automatic firmware updates to be pushed to the machine.
Undoubtedly, the Big+Quiet Formaldehyde is Dyson’s most expensive domestic purifier to date. However, if you are concerned about your health and have the budget and space for it, it may be worth the investment. This is especially true during the increasingly common wildfire seasons.
Dyson announced the Purifier Big+Quiet Formaldehyde range in May 2023, with Australian shoppers being the first to have access to it. The range includes two colorways, but the Dyson-exclusive Satin Dark Blue / Gold model offers additional features such as a CO2 sensor and an extra K-Carbon filter. This model is priced at $1,099 / AU$1,599. The cheaper model, priced at $999 / AU$1,499, excludes these two features but is still available for purchase from Dyson and authorized retailers.
Dyson assures users that the HEPA filter in the Big+Quiet will last for approximately five years, significantly longer than filters in their other purifiers. This factor may contribute to its cost-effectiveness compared to other models.
While the Big+Quiet range may be relatively expensive, especially in comparison to alternatives like the Shark Air Purifier 3-in-1 priced at $400, it is a worthwhile investment for those with large, open homes who prioritize clean air.
Specifications of the Dyson Purifier Big+Quiet Formaldehyde include a price starting at $999 / AU$1,499, 10+ power settings, coverage of up to 100sqm / 1,076sqft, a Glass fiber HEPA filter + K-carbon filter, dimensions of 830mm (h) x 434mm (l) x 415mm (w), and a weight of 11.9kg.
In terms of design, the Dyson Purifier Big+Quiet Formaldehyde may not immediately impress, but it offers functionality and convenience. It resembles a large bowl atop a cylinder and is designed to be placed in a corner of a room. Upon closer examination, it is evident that the size is relative to other Dyson purifiers and bladeless fans. It is also worth noting that the purifier has hidden wheels for easy movement. However, it may feel bulky on carpets.
The purifier’s distinctive design includes a large rim enclosing a smaller dome that houses a square display showing pollutant metrics. The display can be cycled through using the remote control. A small power button is located below the display, and the clean air is propelled through perforations between the rim and the inner dome.
While the Dyson Purifier Big+Quiet Formaldehyde may not have immediate visual appeal, it offers excellent performance and functionality, making it a worthwhile investment for those in need of clean air in their homes.
