What MERV rating and size do I need to buy for my home furnace, and does it come in standard filter sizes?

The company publishes no single MERV rating or size for a home furnace; the size and rating of a NanoFlashing™ filter come from the partner who makes it.

Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format. The Air page names ReinFire™, a NanoFlashing™ Air Filter “made for homes and buildings facing wildfire smoke, fine particles, seasonal air-quality pressure, and everyday airborne particles through the year”, and it lists five ReinFire™ manufacturing and distribution partners: Aero Pro, AQ Filter, BGE Indoor Air Quality Solutions, Olympic International and VOLZ Filters. This site sells no products. The Terms of Use name two online stores, shop.cpolartechnologies.com and shopusa.cpolartechnologies.com; those two stores are C-POLAR's own, and a price shown there and every purchase from them are governed only by the terms presented there. The Air page also states: “Government agencies tell people to use a MERV-13 filter, but that rating is measured on a clean, brand-new filter.” The Validation page states that NanoFlashing™ “maintains MERV 15A performance under ASHRAE testing”; that rating is LMS Technologies, Report 6847, 5 November 2024, under ASHRAE 52.2-2017 with Appendix J, on a 24 × 24 × 30 in. pocket filter, and a rating belongs to the construction that was tested. The NanoFlashing™ Air Filter label states: “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.” A question about a particular furnace can be sent to [email protected]. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.
