Quality Energy/Heat Recovery Ventilators (which are basically mandated by code [in some jurisdictions] in modern construction due to air tightness requirements) should allow you to select the filter with the MERV value that works best for your situation. But to be fair, you may have a good point. Vehicle emissions and tire wear generates particulates consider to be ultrafine (0.1 max nanometer), which is even difficult for HEPA filters to deal with. |
