The researches & technologies behind
You deserve a better
understanding of your air.
Scientists learn the air from sampling, analysis, or microscopic observation. However, as normal people, how can we learn more about what we breathe without the gears and professional knowledge?
Normal air purifiers monitor the air with single sensor that tells one-dimensional data. In Jya, our engineers built three ultra-precise sensors into the air purifier to monitor 5 key elements in air quality: PM2.5/PM10(where pollen lands)/TVOC/Temperature/Humidity. With 100μg/m³ precision, the sensor observes the world on microscopic level, discerning nanometer-level particles, and report the data on OLED screen of Jya Fjord/Fjord Pro.
From the scope lens in laboratory to an OLED screen in your house, Jya creates a private air data station right in your living space. You can learn the air in an intelligent way, rather than smelling, or seeing.
Filters 99.99% of 0.1μm pollutants
Jya NanoGuard™
After years of development and countless times of tries and errors, Jya developed a technique that weaves ultra-thin organic fibers closely together in the filter. Through plasma electret technology, the woven fibers from Jya Nano Guard™ filter are polarized to create a static effect that catches even smaller pollutants atop of physical filtering, while the intricate nano-network structure catches the particles in the air and lock them down on the surface to prevent pollutant escapement. The result? More efficient in air purification than traditional HEPA filter.
Under standard test conditions, researchers took air samples on a set time schedule during the air purification, and analyze the data to see how fast the pollutants decrease over time. The results indicated that after 60 mins of air purification, Jya Nano Guard™ Filter was able to capture 99.99% of 0.1μm pollutants like smog/dust/pollen/bacteria, etc.

3. The counting efficiencf of samples for different particle sizes is as follows:
HEPA Vs. NanoGuard™ Filter
Normal Filter Folding Depth
Shallower, smaller capacity
NanoGuard™ Folding Depth
Deeper, larger capacity
Filter materials need to be folded into a barrel shape for the best efficiency in air purification. To decrease the air resistance, lower the wind noise, and increase the dust capacity of the filter, we implemented the folding depth of the material many times, and chose 21(Fjord)/34(Fjord Pro)mm, a depth that was deeper than most filters’ on the market, as our final solution. Through powerful folding of intricate machinery force, every folding depth remains the same, so that the air would flow through evenly.
Coal Active carbon
with better absorption force
Jya filter‘s material chooses coal active carbon with bigger surface area. 10g of coal active carbon can cover more than 11500m² of area*, equivalent size of 1.5 standard(7140m²) soccer fields, absorbing more odor/TVOCs.
Under standard test conditions, researchers conducted filter tests between plant-based active carbon and coal active carbon. The test results indicated that coal active carbon has a bigger capacity for pollutants. Through comparison, the coal active carbon has more gaps in smaller size, and the distribution with more patterns to contain more pollutants.
