Which cleaning or maintenance steps could change the claimed performance or invalidate the warranty?

The care the filter is given is set by the directions printed on it, and a warranty for a finished product is the warranty of whoever issued it.

The NanoFlashing™ Air Filter label instructs: “Do not wash, vacuum, brush, blow out or reuse this filter.” “Do not cut, fold, trim, bend, puncture or alter the filter or its frame.” “Do not install a filter whose media is torn, crushed, wet or visibly damaged.” “Do not use where this filter would restrict airflow beyond the system's specification.” and “Do not run the system with no filter in the track.” The Terms of Use state that only an express written warranty that identifies C-POLAR as the warrantor creates a C-POLAR warranty, and that a warranty, manual, statement, order confirmation, or other document issued only by a manufacturer, seller, distributor, or other third party does not bind C-POLAR.

What a warranty for a finished filter covers, and what it asks of the buyer, are set by the maker and seller that issued it. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.
