Sqair H11 HEPA Filter
Clean air in your bedroom
The Sqair HEPA filter protects you from Delhi pollution
India’s air pollution is a serious problem. Even though the COVID-19 lockdown had reduced air pollution, Delhi’s air still remained above WHO limits, and cities like Kolkata and Mumbai saw no major improvement in air quality.
The Sqair’s HEPA filter effectively traps particles like PM2.5, dust, pet fur, viruses, and mold, giving you cleaner air in your bedroom. Sleep more easily without worrying about allergies or asthma.

HEPA filters are simple – larger filters can clean more air. The Sqair HEPA filter has an expanded area of 1.55m², equivalent to 22 sheets of A4 paper.

Effectively traps particles as small as 0.005 μm
The Sqair’s H11 HEPA filter can clean 95% of above and below 0.3 microns, PM10 and even 0.005-micron particles.
Why H11? We actually found the H11 filter to be more effective than an H12 filter for the Sqair.

Can HEPA filters capture the coronavirus?
A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. HEPA filters remove particles greater than or equal to 0.3 microns, but virus particles are smaller. The coronavirus measures 0.06 to 0.14 microns in diameter. Are air purifiers then powerless against viruses?
Actually, HEPA filters actually work great at capturing viruses. This is because a HEPA filter works not like a net, but through a process called diffusion. Learn more about how this works here.
How long can I use the Sqair HEPA filter?
HEPA lifespans are tricky. Purifier companies like to give lifespan numbers without proper reasoning. Clearly, the HEPA filter will not last as long in Delhi air as compared to Swiss air.
We estimated the lifespan of the Sqair’s HEPA filter using two methods. From the data, we recommend up to 800 hours of use. This is roughly equal to 3 months if you use the purifier 8 hours a day.
On high mode, this is equivalent to:
Can I wash a dirty HEPA filter?
Unfortunately not. We ran experiments to test this and found that washing HEPA filters does not prolong their lifespan. In fact, washing HEPA filters with water actually decreases performance. That’s why we recommend you replace your Sqair HEPA filter after the maximum hours of use.
At ₹1499 for half a year of clean air, the Sqair HEPA filter offers the best prices for clean air.

Happy customer since 2019 – generally replace the filters at least once a year (just before the Delhi winter smog descends!). Best air purifier and best HEPA filter in terms of performance and value for money 🙂

The best in class – in terms of value, quality, and efficiency. We won’t find them advertising big – unlike other international brands – because this social enterprise keeps its product cost low by saving on brand promotion. Instead, it relies on customers like us, to give our honest feedback. I have been its happy customer since 2018.
