Aquamira
The Aquamira Backcountry Plus Series IV replacement filter is the lightweight, modular answer for anyone running Aquamira's Series IV water filtration system on extended backcountry trips, hunting expeditions, or remote camp setups. This ultralight cartridge adds less than 1 ounce to your pack while dramatically extending your filtration capacity—critical when you're miles from resupply and water quality is unpredictable. Compatible with Aquamira's Frontier MAX and Shift Bottles systems, it gives you the flexibility to upgrade or replace your filter without replacing your whole rig.
With a 1000-gallon rating, the Backcountry Plus filter removes 99% of viruses, bacteria, and cysts—the three main waterborne threats you'll encounter in the field. Aquamira's four-level filtration approach means you're getting serious contaminant removal, not just sediment screening. For hunters, anglers, and backcountry campers who source water from streams, lakes, and uncertain sources, that kind of reliability matters. You're not gambling with your health on day five of a ten-day hunt.
This is a replacement cartridge, so it slots directly into your existing Series IV system. When your current filter has logged its hours, swap it out and keep moving. The modular design keeps your water solution field-serviceable and economical—no need to buy a new filtration system each time a cartridge wears out. For serious backcountry users, that's the difference between a tool you actually trust and one that costs you time and money.
| Brand | Aquamira |

| Filter Rating | 1000 gallons |
| Contaminant Removal | 99% of viruses, bacteria, and cysts |

The Backcountry Plus Series IV filter is compatible with any Aquamira Series IV system, including the Frontier MAX and Shift Bottles. If you're running a Series IV setup, this cartridge is a direct replacement.
The Backcountry Plus filter is rated for 1000 gallons of filtration. Actual lifespan depends on water quality and use frequency—heavily silted water will consume the filter faster than clear stream water.
This filter removes 99% of viruses, bacteria, and cysts, addressing the three main categories of waterborne pathogens you encounter in backcountry water sources.
The cartridge weighs less than 1 ounce, making it practical for ultralight backpacking, hunting, and remote camping where every ounce counts.
