C-POLAR and NanoFlashing™ questions, with the company’s answers and the sources they come from.
Last reviewed: .
How does the Air page describe the NanoFlashing™ Air Filter?
The Air page describes the NanoFlashing™ Air Filter as a filter with a permanent positive polarity, a fixed positive charge, in these words: “The NanoFlashing™ Air Filter attracts and captures ultrafine particles and wildfire smoke, and destroys viruses, bacteria and fungal spores.”
NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The polarity is a positive electric charge at rest. The filter captures airborne particles mechanically and by electrostatic attraction. The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge. NanoFlashing™ is passive. It generates no ozone, releases nothing, and adds nothing to what passes through. The page describes the technology in a filter, not a size, a rating or an airflow; those belong to the finished filter and are stated by the manufacturing partner who makes it.

What evidence applies to the actual installed system rather than a material sample?
The company's evidence is evidence about NanoFlashing™ filter media and about the filters and sites named with it; evidence about an installed system in a particular building comes from that system's own commissioning and measurement.
The Terms of Use state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.” They also state: “Use evidence, specifications, instructions, and warnings specific to the actual finished product and use.” The label for the NanoFlashing™ Air Filter states: “Results in a building depend on the system, the airflow, and how well the filter fits its track.” The nearest published measurements of installed systems are on the Validation page, which reports two identical towers compared at a public hospital in Vancouver, and before-and-after air handling unit measurements at a financial landmark in London, a major international airport in the US and a public university in Melbourne, each over a stated period. At each site the Validation page reports bioaerosols, and at three of them particulates, independently measured with MicronView's 405 nm Bio-fluorescent Air Monitoring System. Each is one building over one period, and it is not a result for another building.

What measured pressure drop and airflow data apply to the exact filter configuration I plan to specify?
This site publishes no pressure-drop or airflow data for any filter configuration; the data for a specific configuration comes from the manufacturing partner who makes that filter.
The Validation page names Eurovent Certita Certification, Certificate No. 15.06.011, which certifies a ten-pocket bag filter at ISO ePM1 70% with an A class energy rating. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter; a rating belongs to the construction that was tested. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format. The label for the NanoFlashing™ Air Filter states a rated airflow and a maximum face velocity, and a replacement point set by pressure drop or by elapsed time, whichever comes first. The company names its manufacturing and distribution partners on the About page and the Air page: Aero Pro, AQ Filter, BGE Indoor Air Quality Solutions, Olympic International and VOLZ Filters.

All questionsDoes a reported rating depend on conditioning or charge state that differs from the marketed configuration?
The polarity in NanoFlashing™ is not the temporary charge that rating standards remove before testing; it is a permanent physical property of the filter media.
The Validation page states: “Industry standards ASHRAE 52.2 Appendix J and ISO 16890 test electrostatic filters after their temporary charge is removed, showing how they perform without it.” NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The air-filtration records named on the Validation page are LMS Technologies, Report LMS#9904, 28 April 2025, a single-pass fractional efficiency test on a 24 × 24 × 2 in. pleated air filter in an ASHRAE 52.2 test duct, in accordance with standard LMS aerosol test procedures, and Report 6847, ASHRAE 52.2 with Appendix J, and Eurovent Certita Certification, Certificate No. 15.06.011. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter, and Report 6847 is on a 24 × 24 × 30 in. pocket filter; a rating belongs to the construction that was tested. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.

Does a laboratory result tell me how the complete product will perform in my room or water system?
A laboratory result states what that test found on what it tested; how a complete product performs in a room is a property of the room, the system and the installation.
The Terms of Use state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.” They also state: “Use evidence, specifications, instructions, and warnings specific to the actual finished product and use.” The label for the NanoFlashing™ Air Filter states: “Results in a building depend on the system, the airflow, and how well the filter fits its track.” The nearest published measurements of installed systems are on the Validation page: two identical towers compared at a public hospital in Vancouver, and before-and-after air handling unit measurements at a financial landmark in London, a major international airport in the US and a public university in Melbourne, each over a stated period.

How do sealing, bypass, frame design and installation orientation affect the assembly evidence?
Sealing, bypass, frame design and installation orientation decide how much of the air actually passes through the media; the company's evidence is about NanoFlashing™ filter media and about the filters and sites named with it.
The label for the NanoFlashing™ Air Filter instructs: “Check that the filter sits square in the track with no gap at the frame. Air that passes around a filter is not treated by it.” It instructs that the filter is fitted with the airflow arrow pointing toward the blower, that is, in the direction the air travels. It states: “Improper installation can reduce airflow or damage the equipment.” and “Results in a building depend on the system, the airflow, and how well the filter fits its track.” The filter captures airborne particles mechanically and by electrostatic attraction, and it can act only on the air that passes through it. The company publishes no frame, gasket or bypass test for an assembly; the frame and the seal are part of the finished filter.

What documented checks are needed after installation to confirm fit and operation?
The label for the NanoFlashing™ Air Filter sets the checks for the filter itself: that it is fitted with the airflow arrow pointing toward the blower, and that it sits square in the track with no gap at the frame.
The label instructs that the system is switched off at the thermostat or at the unit's disconnect before the filter access is opened, that the used filter is removed and discarded as directed under Storage and Disposal, and that the access panel is closed and the system switched back on. It states: “Air that passes around a filter is not treated by it.” and “Improper installation can reduce airflow or damage the equipment.” It also instructs: “Do not use where this filter would restrict airflow beyond the system's specification.” The label covers the filter; the commissioning record for the system, including airflow and pressure readings after the change, belongs to the operator of that system.

What evidence supports any claimed energy saving after accounting for actual airflow and filter loading?
The company does not claim an energy saving for a filter in a system it has not measured.
On the Validation page the company reports a six-month measurement at a financial landmark in London, March 2024 to September 2024, made before and after the air handling unit filters were changed to NanoFlashing™, in which particulates, bioaerosols and energy were all measured lower. The Validation page also names Eurovent Certita Certification, Certificate No. 15.06.011, which certifies a ten-pocket bag filter at ISO ePM1 70% with an A class energy rating; a rating belongs to the construction that was tested. The Terms of Use state: “A reported result describes only what the identified test found.” They also state: “Use evidence, specifications, instructions, and warnings specific to the actual finished product and use.” That is one building over one period, measured after a filter change in its own air handling units; it is not an energy figure for another system, another filter configuration or another loading condition.

What temperature, humidity and loading limits are documented for the proposed installation?
The label for the NanoFlashing™ Air Filter sets the operating conditions: dry air only, at or below the rated airflow and maximum face velocity, with replacement at a stated pressure drop or after a stated interval, whichever comes first.
The label instructs: “Use in dry air only. Do not use in ducts carrying liquid water, steam or oil mist, or anywhere the media may become wet.” and “Do not install a filter whose media is torn, crushed, wet or visibly damaged.” For storage it instructs that the filter is kept flat or on edge in the original packaging, indoors and dry, away from direct sunlight and moisture. The conditions tested, listed on the Validation page, are heavy dust loaded, fast air flow, used filter for 1 year, after 60 washes, after 2 years of storage, and after 60C for 64 days. The company publishes no temperature or humidity range for a particular installation; those limits are set by the partner who makes the finished filter.

How does a downstream filter interact with the pressure loss of this material?
How a downstream filter interacts with the pressure loss of this media is a system calculation the company does not publish, and it is made from the data the maker of each finished filter supplies.
The company publishes no multi-stage design guidance and no pressure loss figure for the media. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. The filter captures airborne particles mechanically and by electrostatic attraction. The label for the NanoFlashing™ Air Filter instructs: “Do not use where this filter would restrict airflow beyond the system's specification.”

Is the filter suitable for airflow that reverses direction during normal operation?
The filter is fitted and used in one direction, so it is not offered for airflow that reverses during normal operation.
The label for the NanoFlashing™ Air Filter instructs that the filter is fitted into the filter track with the airflow arrow pointing toward the blower, that is, in the direction the air travels. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter, and the polarity is a positive electric charge at rest. The filter captures airborne particles mechanically and by electrostatic attraction. The company publishes no test of reversing airflow; an application with reversing flow is discussed with the maker of the finished filter, and enquiries go to [email protected].

Could a tightly packed installation prevent air from reaching part of the filter face?
A tightly packed installation can leave part of the filter face without airflow, and the label requires the filter to sit square in its track with no gap at the frame.
The label for the NanoFlashing™ Air Filter instructs: “Check that the filter sits square in the track with no gap at the frame. Air that passes around a filter is not treated by it.” It instructs that the filter is fitted with the airflow arrow pointing toward the blower, that is, in the direction the air travels. It states: “Improper installation can reduce airflow or damage the equipment.” and “Results in a building depend on the system, the airflow, and how well the filter fits its track.” The filter captures airborne particles mechanically and by electrostatic attraction, and it can act only on the air that passes through it. The company publishes no frame, gasket or bypass test for an assembly; the frame and the seal are part of the finished filter.

What effect does filter-frame deflection have at maximum airflow?
Frame deflection at maximum airflow is a property of the finished filter's frame, which the company does not specify.
The company publishes no pleat geometry, media area, frame specification or deflection data. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format, and the manufacturer and seller of a finished product are responsible for its design, manufacture, labeling, instructions, claims, sale, and warranty. The label for the NanoFlashing™ Air Filter instructs: “Do not cut, fold, trim, bend, puncture or alter the filter or its frame.” and “Do not install a filter whose media is torn, crushed, wet or visibly damaged.” The label also states a maximum face velocity, which is the upper condition the filter is to be used at or below.

Can a filter retrofit change the balance between supply and exhaust ventilation?
It can: the filter's resistance adds to the pressure the system's fan works against, and the label directs that it is not used where it would restrict airflow beyond the system's specification; what that means for the balance between supply and exhaust is settled by that system's own measurements, and the company does not publish a ventilation balance assessment.
