World’s 1st Nanoporous Synthetic Iron Oxide Active Bed Air Filter

Share Article

Engineered Data, LLC has designed, tested and filed a patent application for the first commercial filter to use military-grade nano-porous synthetic iron oxide particles for remediation of small metal + inorganic pollution particles that standard hepa filters + activated carbon miss. Originally designed for air and gas filtration, with minor modifications, this filter can also be used for water filtration.

Five factors make Engineered Data's sorbent + filter revolutionary:

  •     1st, where filters that use nanotechnology today rely on membrane nano-fibers to deliver nano-scale remediation performance, Engineered Data's filter uses sorbent particles, not membrane fibers.
  •     2nd, the traditional method of manufacturing nano-fibers is electrospinning, which often requires dangerous solvents. New extrusion methods like meltblowing + nanotubing produce nano-fibers that lack the homogeneity that electrospun nano-fibers possess. Engineered Data's sorbent particles are manufactured by a simple, safe, inexpensive, and proprietary process known only to Engineered Data and its project development partners. Other applications for Engineered Data's sorbent exist in petroleum refining, medical applications and other markets, but these applications are unexplored.
  •     3rd, nano-particles pose a health threat, as particles with small nanometer range diameters can permeate human tissue and organs. Engineered Data's sorbent particles, having micron range diameters that are +/- 1,000 times larger than nano-particles, virtually eliminate this health risk.
  •     4th, in preliminary hygroscopic weight gain tests, Engineered Data’s sorbent particles displayed adsorption speed + capacity more than twice that of the traditional filter sorbents activated carbon and silica gel.
  •     5th, Engineered Data's filter design incorporates active sorbent bed + self-cleaning membrane functions to counter particle agglomeration, known in micro and nanotechnological applications to degrade sorbent capacity + product life.

Preliminary testing suggests Engineered Data’s filter will perform best in any environment known to possess high concentrations of small (<2.5 microns in size) metal and/or inorganic particles, where remediation speed is important. For outdoor air pollution remediation, environments known to have high concentrations of these particles include sites near [1] Superfund sites, [2] volcanoes, and [3] coal fired power plants. For indoor air pollution remediation, environments known to have high concentrations of these particles include [1] lead paint remediation sites, [2] indoor firearm shooting ranges, and [3] mines. The Engineered Data filter may also have applications where concentrations of small metal and/or inorganic particles are low but air quality is critical; for example, in [1] semiconductor manufacturing, [2] hospital neonatal & ICU rooms, and [3] nursery + elementary schools.

The image displays Engineered Data’s patent-pending 2nd generation filter, which possesses a secondary compartment and a top membrane that the 1st generation prototype does not.

Emerging technologies are nearly always prohibitively expensive when first introduced. Engineered Data's sorbent and filter, both currently made by hand, are no exception. The surest way to drive down emerging technology prices is with large scale demand.

For a limited time, Engineered Data is offering filter test drives, as a type of feasibility test, to entities with a large scale interest in small particle remediation. A filter test drive places Engineered Data's patent-pending 2nd generation filter, operated by Engineered Data and its technology partners, monitored by the feasibility tester's technicians, into a test environment relevant to feasibility testing organization, to [1] measure small particle remediation performance, [2] share test results, and [3] discuss application(s) feasibility.
