Replacement HEPA filter for The Sqair
- The HEPA filter is the core of any purifier. We analysed the performance of over 30 different filter types before selecting the H11 filter. Why? When we tested The Sqair with the H12 filter, the airflow was reduced so although the H12 captured more particles in the first pass, the H11 gave 27% more clean air overall. The H11 captured 95% in a single pass and 99.75% in the second pass. When matched with the fan power of The Sqair, the H11 is the most efficient grade filter to clean the air
- Sqair HEPA has a huge surface area: 1.5 m2 of high-grade HEPA material equivalent to 22x A4 sheets
- Sqair HEPA captures PMs, pollen, moulds, allergens, dust etc. It even captures viruses and nanoparticles
- Size: 295 x 295 x 50 mm
- Filter lifespan - Up to 1400hrs on the highest speed (see product description)
Our HEPA filter has a lab-tested lifespan of 6 months if used 8 hours a day in a 40m2 room. As lab conditions don’t mimic real life and there are so many variables that can affect the life of your filter, we put our HEPA filter to a real-life test by running it in a Beijing apartment with the windows open. Our data shows a lifespan of 1400 hours, after which the efficiency is down to 50% which is pretty similar to the lab results. But remember to adjust this figure to your own environment. For example, if you live in a less polluted city than Beijing, run the purifier in a smaller space than 40m2 or you run it on a lower setting, your filter will last longer.
