What Medify Air H13 HEPA Filter's Out
2.5-10 microns
Dust contains various tiny particles that may lead to irritation and allergic responses, like pollen, smoke, bacteria, ash, and dead skin. Medify Air's H13 HEPA filter technology aids in capturing the smallest dust particles.
5-10 microns
The microscopic fragments of deceased skin and hair that an animal sheds are recognized as dander and can incite allergic responses in certain individuals. Fortunately, our air purifier is meticulously crafted to eliminate pet dander.
2-100 microns
Moulds quickly proliferate by releasing numerous microscopic spores that travel through the air and can cause respiratory irritation. If left unchecked, mould can harm your health, damage your furniture and fabrics, and create a musty odour. The Medify Air air purifier helps filter out mould spores, ensuring you breathe safe and clean air.
1-3 microns
Single-cell organisms survive on non-living surfaces and can multiply rapidly, leading to infection and disease. The Medify Air air purifier uses HEPA 13 filtration to filter out bacteria, ensuring clean, safe indoor air.
0.1-0.5 microns
This virus spreads through small liquid particles in the air when an infected person breathes, talks, or sneezes, ranging from 0.1 to 0.5 microns. The Medify Air unit's medical-grade HEPA 13 filtration technology filters out viruses, even COVID-19 particles.
Our HEPA 13 filter removes 99.99% of particles up to 0.1 microns, targeting mould, dust, pollen and pet dander.
