Most air purifiers stop at HEPA-13 and a colour ring, then call it good air.
STĀCK’s four-stage filtration with HEPA-14 lets through 10x fewer particles than HEPA-13, down to 0.3 microns. Its high-precision SenseQuad™ tracks four environmental parameters: PM2.5, PM10, temperature, and humidity, to give you a true reading of your air quality.
Your home deserved this a long time ago. We took three years to build something worthy of it.
Good air days are coming soon
Don't worry, be HEPA-14
Indian air comes with its own mix of pollutants: construction dust, pollen, agarbatti smoke, cooking fumes and more. STĀCK was designed for this: clinical-grade HEPA-14 filtration captures particles as small as 0.3 microns, about 200 times thinner than a human hair.
0.05% vs 0.005%. Doesn't sound like much.
Until you have to breathe it in.
HEPA-13 filters stop 99.95% of particles. HEPA-14 stops 99.995%. That's 10× more efficient at stopping the finest particulate matter
SenseQuad™
Four Parameters. One display. Zero Guesswork.
PM10
The visible villain. Dust, pollen, pet hair, the stuff you can see floating in the air. PM10 tracking tells STĀCK when the larger particles rise, so it can respond before you sneeze.
PM2.5
Invisible, odourless particle that goes straight to your lungs. 0.3 microns wide. SenseQuad™ watches it so you don’t have to wonder.
Relative Humidity
Humidity determines how fast pollutants travel, how long they stay airborne and how your body responds to them. Tracked live. Factored in automatically.
Temperature
Pollution levels change with temperature because pollutants and Volatile Organic Compounds (VOCs) release faster in the heat.
Thou shall not pass. Not even at 0.3 microns.
DeepStack™ sends your air through four stages, each built for a different pollutant.
DeepStack™ sends your air through four stages, each built for a different pollutant.
1. Polyamide Pre-Filter
The stage most purifiers skip. Catches finer dust and pollen before they can clog the HEPA core, which is why STĀCK’s HEPA-14 lasts longer than single pre-filter air purifiers.
2. Blue Polypropylene Non-woven Pre-Filter
Hair. Dust. Anything big enough to see. Gone before it gets anywhere near the filter that matters. Washable, reusable and designed to last.
3. Clinical Grade HEPA-14
99.995%. That’s not a rounding difference from 99.95%. It's 10× more efficient at eliminating the particles that enter your bloodstream.
4. Activated Carbon
Volatile Organic Compounds (VOCs) are gaseous pollutants released by paint, cleaning products and cooking. Activated Carbon traps them, along with the smells they bring.
