What FDA pathway, if any, would apply to the specific proposed medical use?

A submission for a finished device is made by the party that sponsors that device, for that device, and nothing held by another party carries over to it.

The Terms of Use state that, as of their effective date, the Medical devices chapter describes a Research Application, and that it does not describe a finished product currently available from C-POLAR for that use. They also state: “Do not use Site Content to diagnose, treat, or make a patient-care or infection-control decision,” and: “Laboratory results report the organisms, particles, and endpoints that were measured. C-POLAR makes no clinical or medical claim from them.”

The Terms of Use state: “A citation, quotation, name, logo, link, or third-party test does not by itself mean that the third party sponsors, endorses, certifies, or approves C-POLAR, a C-POLAR product, a Site claim, or a proposed use.”

The NanoFlashing™ Air Filter label states: “It is not a medical device and is not intended to diagnose, treat, cure or prevent disease.”

Can a workplace purchaser treat an EPA identifier as evidence of OSHA suitability?

An EPA establishment number identifies the place where an article was produced, and it identifies nothing else; it is not a finding about workplace suitability.

A device is defined at 40 C.F.R. § 152.500(a) as “any instrument or contrivance (other than a firearm) intended for trapping, destroying, repelling, or mitigating any pest or any other form of plant or animal life (other than man and other than a bacterium, virus, or other microorganism on or in living man or living animals) but not including equipment used for the application of pesticides (such as tamper-resistant bait boxes for rodenticides) when sold separately therefrom.” NF Technical Products Inc. classifies the NanoFlashing™ Air Filter as a device under Section 2(h) of the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. § 136(h), and that definition. Its Statement of Classification states at 3.6 that a charge is a physical property, that it is not a substance or a mixture of substances, and that the filter therefore incorporates no substance or mixture of substances to perform its intended pesticidal purpose.

Under 40 C.F.R. § 152.500(b) a device is not required to be registered under FIFRA section 3, and the requirements that apply instead are labelling; establishment registration and reporting; books and records; inspection of establishments; violations, enforcement and penalties; import and export; child-resistant packaging; and the Agency's authority under FIFRA section 25(c)(4). For the same filter in the European Union, C-POLAR Technologies, Inc. classifies it as neither a biocidal product nor a treated article under Regulation (EU) No 528/2012. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.

The company classifies its own article. No agency has approved, registered or cleared the filter, and for a device there is no such approval to obtain, because EPA does not review a device for safety or efficacy before it is sold.
