HEPA filters capture particulate pollution like PM2.5 and pollen, and are the key to clean air. This is the replacement H13 HEPA filter for the Ladakh air purifier.

Ladakh H13 HEPA Filter

Clean air in your office and hospitals

The Ladakh HEPA protects you from Delhi pollution

India’s air pollution is a serious problem. Even though the COVID-19 lockdown had reduced air pollution, Delhi air still remained above WHO limits, and cities like Kolkata and Mumbai saw no major improvement in air quality.

The Ladakh’s HEPA filter effectively traps particles like PM2.5, dust, pet fur, viruses and mold. You won’t have to worry about your allergies or asthma any longer!

Ladakh HEPA’s massive area captures 99.95% of pollutants

The Ladakh HEPA filter is huge — 20 times the size of our Original DIY HEPAs.

We tested over 10 different HEPA materials before deciding on using an H13, 99.95% grade HEPA filter. That means it can capture 99.95% of those particles above (and below) 0.3 microns!

Are HEPA filters effective against COVID?

A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. HEPA filters removes 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 often should I change the HEPA?

We tested a HEPA in real Beijing air for 200 days to get a sense of how long HEPAs last in real Beijing air.

Based on that data, Paddy estimated a HEPA lifespan of 5280 hours for the Ladakh. This is roughly equal to 22 months at 8 hours of use every day. If you use it more or less, you can calculate lifespan using the total number of hours below.

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 Ladakh HEPA filter after the maximum hours of use.

At ₹11,799 for two years of clean air, the Ladakh HEPA offers you the best prices for clean air.

Time to change the HEPA?

You’ll only need to change it every 22 months, but we still tried to keep things simple.
