Vent-Axia ISO ePM2.5 70% Filter 411692

Vent-Axia 411692 — Sentinel Econiq M, L, MCP, LCP and Cool-Flow ISO ePM2.5 70% (F7) Filter, 1 per Pack.

The Vent-Axia 411692 is the genuine OEM ISO ePM2.5 70% (F7) supply air filter for the Lo-Carbon Sentinel Econiq M, L, MCP, LCP, and Cool-Flow MVHR units, supplied as a single filter per pack. Formerly classified as F7 under the EN779 standard and now rated as ISO ePM2.5 70% under ISO 16890, it is the highest-grade supply filter available for this unit family — designed for dwellings in urban, roadside, or high-pollution environments where removing fine particulate matter from the incoming supply air is a priority for occupant health and indoor air quality.

The Highest Supply Filter Grade for the Econiq M/L Range

The F7 sits at the top of the Sentinel Econiq M/L filter hierarchy. Where the G4 standard filter captures coarser particles and the M5 pollen filter (411691) captures particles down to 10 microns, the F7 goes further — capturing 70% or more of particles in the PM2.5 size range. At this level the filter intercepts the very fine particulate matter found in exhaust fumes, industrial emissions, smoke, mould spores, and bacteria — particles small enough to penetrate deep into the respiratory system. For occupants in city-centre properties, homes near busy roads, or any dwelling where outdoor air quality is a concern, the F7 provides the most comprehensive supply air filtration the Econiq M/L system can deliver.

Supply Air Filter Only — Extract Uses Standard G4

The Sentinel Econiq M, L, MCP, LCP, and Cool-Flow units use separate filters for supply and extract air paths. The 411692 replaces the supply air filter only — the G4 extract filter continues to protect the heat exchanger and is replaced separately using the G4 two-pack. Because the F7 is a denser filter medium than the G4 or M5, it will load up with captured particulate more quickly in heavily polluted environments.
