One AraX filter purifies up to 300 liters of water — that's double what most competitors offer. For the average person drinking 2-3 liters daily, one filter lasts about 3-4 months. The smart chip tracks usage in real-time, and the app notifies you a week before it's time to replace. No guessing, no sudden drop in water quality.

Absolutely. ARAX is built for outdoor adventures. The nano-filter removes 99.9% of bacteria, viruses, protozoa, and sediment from natural water sources. The UV lamp adds an extra layer of protection by killing any remaining microorganisms. Whether you're filtering from a mountain stream or a questionable fountain, ARAX makes it safe to drink. Just avoid saltwater or chemically contaminated industrial water.

Yes, but rarely. The built-in battery powers the UV lamp, smart chip, and app connectivity. On a full charge, ARAX lasts 2-3 weeks with normal use (UV cycle runs automatically after each fill). Charging takes about 2 hours via USB-C. A low-battery alert appears in the app when it's time to plug in.

The mineral cartridge contains magnesium, calcium, potassium, and beneficial probiotics — all naturally sourced and carefully dosed for daily hydration. These are the same minerals your body loses through sweat and activity. The formula is designed for everyday use and supports energy, focus, immune function, and recovery. It's safe for most people, but if you have specific medical conditions or dietary restrictions, consult your doctor before use.

Let's do the math. In the US, 300 liters of bottled water costs around $60. In Europe, it's closer to €100. One ARAX filter costs $30 and handles the same 300 liters. That's a 50% savings in the US and over 60% in Europe. Plus, you're eliminating 200+ plastic bottles from landfills. Over a year (4 filters), you save $120-200 while reducing waste and microplastic exposure.

Yes, when empty. TSA and most international airport security allow empty reusable bottles through checkpoints. Once you're past security, fill your ARAX at any fountain or tap — even questionable airport water becomes clean and safe. The Travel version is also more compact and durable, making it perfect for carry-on luggage and rough handling.

ARAX's nano-filter is designed to handle tough conditions without clogging. Unlike cheaper filters that block up quickly with sediment, our multi-layer filtration system processes particles in stages. The pre-filter catches large debris, while the nano-membrane handles microscopic contaminants. If you're filtering extremely muddy water, flow rate may slow slightly, but the filter won't fail. Regular backflushing (instructions in the app) keeps it running smoothly.

Many smart bottles claim to filter water, but few provide proof. ARAX filters are independently tested and certified by accredited US laboratories to meet NSF/ANSI standards for contaminant removal. We publish our test results openly — you'll see exactly what gets filtered and by how much. Competitors often skip certification because testing is expensive and rigorous. We don't cut corners on safety. Your health depends on it.
