What is a HEPA vacuum?
HEPA (High Efficiency Particulate vacuums are vacuums that contain filters that trap extremely small particles. A high-quality HEPA vacuum can trap 99.99 percent of all airborne particles larger than 0.3 microns.
Is a HEPA filter vacuum worth it?
Yes, if you suffer from asthma or have allergies, a vacuum with a dust-removing HEPA filter is a great bang for your buck. Not only will your living environment be free of dust and allergens, you’ll be able to focus better, be more productive, and breathe cleaner air.
Why are HEPA filters so expensive?
HEPA filters have to move enough air to pull small particles into the air stream and through the filter media. HEPA filters also require extremely dense media.

What are HEPA filters?
HEPA means ‘High-Efficiency Particulate Air’. It is a label applied to filters that can trap 99.97% of particles as small as 0.3 microns. HEPA filters are known to improve the air quality in your home and help you live in the most clean environment possible.
The HEPA test and certification process was first established in 1983. The development of HEPA filters first started during WW2.
You probably didn’t know that the US created the first HEPA filter which was intended to capture radioactive scraps released while creating the atomic bomb.
This was happening during the Manhattan Project. Eventually, experts found out 0.3 micron particles escaped air filters, which meant vacuums didn’t fully suck up all the dust in the air.
Nowadays, HEPA filters are designed with interlaced glass threads. These threads are bent and twisted in multiple directions to produce a threadlike maze, and as particles cross this web, they are then taken out of circulation.
How do HEPA filters work?
Below is a brief overview of how HEPA filters works:
- Sieving: The airstream carries a particle between the two fibers. Then, the particle gets trapped because it is bigger than the gap.
- Direct Impaction: Big contaminants move in a direct trail, hit a fiber, and then end up clinging to it.
- Diffusion: Tiny particles are more likely to hit and cling to fibers since they travel more unevenly than bigger particles.
- Interception: Due to inertia, particles remain on their track and quickly stick to the sides of the fibers.
