This is the replacement HEPA filter for Smart Air India’s Sqair air purifier. HEPA filters capture particulate pollution like PM2.5 and pollen and are the key to clean air for you and your loved ones.


Sqair H12 HEPA Filter

Clean air in your bedroom

The Sqair HEPA filter protects you from Delhi air 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.







Huge surface area captures 99.5% of pollutants

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 H12 HEPA filter can clean 99.5% of above and below 0.3 microns, PM10, and even 0.005-micron particles.

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, no. 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.

    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.
