HEPA is a very qualitative air purifier that is used in conditioning systems, HVAC units, cleaning units, etc. Unlike cheaper industrial and regular constructions, HEPA air filter traps exceptionally tiny pollutants (smaller than 0.3 microns): bacteria, fumes, smoke, spores, etc.
How do HEPA filters for AC work?
It catches air contaminants in a complicated network of synthetic fibers. Type of filtering depends on particle diameter & size (it might be diffusion, sieving, etc). Large specks are caught through sieving system or internal impaction: this way, pollutants cannot penetrate fibers and stay on their surface. Mid-size pollutants are blocked by interception while tiny air molecules start colliding with HEPA air filter and stay on fibers.
Coupled with carbon layers, such construction interlocks petty particles and allows for reaching ideal air purity. Odors, chemicals, smoke or bacteria are caught and totally eliminated. Thus, consumers buy HEPA filter when they need to ensure total cleanliness in their house. This is a perfect option for houses with kids, allergic & sensitive people, pets, or properties located in polluted area.
Advantages of HEPA filtration:
- Captures small or ultra-fine specks;
- Compatible with various HVAC units, vacuum cleaners;
- Availability & cost-efficiency;
- Should be rarely replaced (once in 3-6 months).
Are all HEPA filters the same?
There is slight difference between models complying with European standards and options made to comply with American standards.
- European filters can catch 85% of pollutants 0.3 micron in diameter.
- American models can catch 99.97% of pollutants of the same or smaller size.
If you see a model labeled “Captures 99.9% of particles”, it means it’s good at catching large ones, but not necessarily ultra-small ones. Note to the size/diameter of bits mentioned on labels.
Note that not all models are designed to remove allergens from air. It does a great cleaning job in vacuums, but should be combined with other filters to reach exceptional cleanliness. Same applies to HVAC systems & conditioners. Read label or ask seller to inform you about quality of material.
