Source: aquamira.com (verified 2026-08-11). Aquamira's own Frontier MAX product page confirms an interchangeable Series IV cartridge system, with the Backcountry+ cartridge rated for 1,000 gallons (3,785 L) of bacteria removal and a separate Worldwide cartridge rated for 120 gallons of virus removal, plus Miraguard antimicrobial treatment to suppress microbial growth in the housing. The page does not publish a micron pore-size rating, a flow-rate figure, a product weight, or field-cleaning/backflushing instructions, so those fields are left null/false rather than assumed. Protozoa removal is not explicitly claimed on either cartridge variant on this page, so the combined removal descriptor reflects only the tested claims (bacteria on Backcountry+, plus virus on the separate Worldwide SKU).
