The AirFanta 3Pro is a room air purifier that boasts an impressive 702 m³/h Clean Air Delivery Rate (CADR) at a significantly lower cost (S$195, or 3.6 CADR per S$) than other competitors.
In this post, we find out how that was made possible by looking into the components that make up the AirFanta 3Pro.
How room air purifiers work
First, a quick introduction to how room air purifiers work.
Room air purifiers are made up of two basic components – a mechanical fan and a filter. The fan pulls air through the filter, which traps harmful contaminants such as viruses, bacteria, dust, smoke, and allergens. The cleaned air is released through the filters and mixes with the rest of the room.
Some room air purifiers may employ other air cleaning technologies, such as ionizers and UV, but the bulk of the work is usually done by the fan and the filter.
Four-air-intake design
The total surface area of the filter is the largest determining factor of how much air is filtered. A filter with a large surface area can filter more air than a filter with a small surface area.
Most room air purifiers in the market, regardless of their air cleaning performance, make use of a single air filter. Some manufacturers have also developed dual-intake room air purifiers, aka room air purifiers that make use of two filters instead of one. Why is that?
That is because you can double the amount of air that is cleaned by adding one more filter to an air purifier. This means that if an air purifier is using two 29 cm by 29 cm filters (841 cm²), the total filtration surface area is 1,682 cm².
Unlike most room air purifiers in the market, the AirFanta 3Pro makes use of four 29 cm by 29 cm filters, equivalent to a total filtration surface area of 3,364 cm², effectively increasing the volume of air filtered in a single pass.
The four filters are placed in a highly compact cube formation, allowing air to be filtered efficiently and quickly.
Highly powerful computer fans
Besides filtration surface area, the type of fan that is used also plays an important role in the air cleaning performance of an air purifier.
Since the COVID-19 pandemic started, engineers and air quality experts across the globe have found a new and highly efficient way of increasing airflow while reducing noise level and energy consumption – computer fans.
Instead of having a large single fan, the AirFanta 3Pro makes use of four proprietary computer fans that are powerful, quiet, and energy-efficient.
Small footprint
By quadrupling the number of filters and placing them in a cube formation, the AirFanta 3Pro takes up significantly less space than other products that offer a similar CADR.
While most air purifiers contain huge chunks of metal and plastic that take up a lot of volumetric space, the AirFanta 3Pro keeps things simple with four filters, one small plastic base and four powerful computer fans. This highly efficient and compact configuration allows production and shipping costs to be kept in check, as compared to other air purifiers with similar air cleaning performance.
Take for example the IQAir HealthPro Plus, which is estimated to have a maximum CADR of 425 m³/h, slightly over half of that of the AirFanta 3Pro. Due to its large body, it has a 1.55 m² footprint, is about 71 cm tall, and weighs 15 kg. In comparison, the AirFanta 3Pro has a 1.02 m² footprint, is 32 cm tall, and weighs just 2.28 kg.
Doing away with unnecessary features
Many room air purifiers in the market come with features such as smart app connectivity or claim to improve indoor air quality through ionizers and UV, which help significantly increase the markup and profit of those products.
As we explained earlier, the bulk of an air purifier’s job is performed by the fan and the filter. Thus, AirFanta decided to do away with unnecessary features and squeezed every single dollar into increasing the AirFanta 3Pro’s CADR, while maintaining a good balance in energy usage and noise level.
What about filter replacements?
Filter replacements also cost significantly cheaper than products that offer similar air cleaning performance.
The retail price of an AirFanta 3Pro (CADR: 702 m³/h) filter replacement set (4 filters in 1 set) is S$88, while the novita A8i’s filter replacement set (2 filters in 1 set) retails for S$268.
Assuming the AirFanta 3Pro’s filters are replaced once every 12 months, and the novita A8i’s filters are replaced once every 2 years per the manufacturer’s recommendation, in 2 years, the average filter replacement cost for AirFanta 3Pro would be S$176, 34% lower than the novita A8i’s S$268.
Conclusion
To sum it up, the AirFanta 3Pro offers superior air cleaning performance at a low cost for the following reasons:
- Four filters and four powerful computer fans increases fficiency and the volume of air that can be cleaned in a single pass
- Compact design helps to bring down production and shipping costs
- Doing away with unnecessary features to focus on providing a high CADR while balancing energy usage and noise level
