The short answer

For most homes, stored water is the simplest, most reliable emergency plan, so SmartWaterBox is the easier starting point. Water Freedom System suits DIY-minded readers who want a project, with realistic expectations about output.

SmartWaterBox

Focuses on keeping a household supplied with water in an emergency, covering storage and alternative sources per the vendor.

Water Freedom System

A long-running guide about a device that condenses water from air. Output depends heavily on humidity, temperature and power, so treat any figures as the vendor’s claims.

Drinking water safety

Drinking water must be stored and treated safely. Follow your water company, gov.uk or CDC guidance, and treat DIY methods as a supplement.

Safety first: generators, batteries, fuel and home-built power systems can cause fires, electric shock and carbon-monoxide poisoning. Never run a generator or fuel heater indoors, fit a CO alarm, and use a qualified electrician for anything connected to your home wiring. Drinking water must be properly treated: follow official guidance (in the UK, your water company and gov.uk; in the US, ready.gov and the CDC). For official emergency-preparedness advice, see gov.uk/prepare or ready.gov.

Common questions

How much water should I store?

Official guidance often suggests several litres per person per day for a few days. Check gov.uk or ready.gov for current advice.
