This air purifier has two filters – a 4” deep carbon pre-filter and a 12” deep main filter.
- Better than HEPA (99.99%+ at 0.3 microns)
- Main filter has 4-39X more filter media - lasts longer and quieter
The main filter is the same industrial filter that is trusted by hospitals and removes much more than any true HEPA filter. It has 195 sq feet of filter media and that is more than 4 times our closest competitor and up to 39 times what other air purifiers have.
Most HEPA air purifiers have a thin filter and while marketed as HEPA they do not achieve HEPA performance. We have tested just about every filter that is out there and haven't found one that can meet this standard. This is important because they are not as effective in removing the smallest sized particles which are the one's that stay suspended in the air the longest and get breathed deep into your lungs. To remove these particulates an industrial grade filter is required, the more filter media the better.
Having more filter media means the main filter will last longer (3+ years) and it creates less air resistance. By not having to work as hard the motor can spin at a slower, quieter rate.
These are the same filters used in Hospital Operating Rooms, Clean Rooms, the Nuclear Industry, Containment units, Laboratories, and Pharmaceuticals. Filters are custom sized and made by the only company in the US that makes its own HEPA media.
