Shelf Life
Product is designed for long-term indoor storage and labeled with the manufacturing lot and expiration date. Follow the date markings on the pouch or case when planning rotation cycles as part of your emergency preparedness program.

Storage
Store in a cool dry indoor location away from direct sunlight, cleaning chemicals, and other contaminants. Pouches may be kept in classrooms, offices, closets, or other indoor areas. Avoid storage near chemicals, fuels, or strong odors that may permeate the pouch material. Protect cases from puncture or crushing during storage and handling.

Use in Emergency Kits
The easy-open pouch design supports hygienic distribution to students, staff, elderly individuals, or evacuees without shared containers. Single-serve units assist with rationing and reduce waste during short-term emergency events.

Why choose water pouches instead of regular bottled water?
Emergency water pouches provide a controlled serving size with a manufacturer-stated 5-year shelf life and US Coast Guard approval. The multi-layer foil pouch provides a complete barrier to light and oxygen that plastic bottles cannot match over extended periods, and the compact format simplifies distribution during emergencies. Unlike regular bottled water, pouches are single-serve, tamper-evident, and designed specifically for emergency storage and distribution.

How much emergency water should I plan per person?
A common planning approach is 8–16 oz of stored emergency water per person per day for short-term hydration needs during a shelter-in-place or evacuation event. With a 4.2 oz pouch, many organizations plan 2–4 pouches per person per day as an initial reserve while additional water sources are accessed. These are minimum reserves — FEMA recommends 1 gallon (128 oz) per person per day for full hydration and sanitation needs.

Is the water purified?
Yes. Mainstay emergency water is triple purified using reverse osmosis and UV sterilization, then vacuum sealed in a foil pouch for long-term storage. Kosher certified. Made in the USA. No additives or preservatives required.

Is the packaging free of BPA and harmful chemicals?
Yes. The multi-layer foil pouch eliminates concerns about plastic degradation during long-term storage and avoids BPA, forever chemicals, and other harmful substances associated with some plastic water packaging.

Can the pouch be resealed or refilled after opening?
No. Mainstay water pouches are single-serve and are not designed to be resealed or refilled after opening. For a resealable emergency water option, Ready H2O 20-Year Emergency Drinking Water in a rugged HDPE bottle is available and can be resealed, consumed over multiple hours, and refilled from treated water sources.

What makes Mainstay different from other pouch water brands?
Mainstay features an easy-open pouch design that makes it particularly accessible for elderly individuals, children, and anyone who may have difficulty opening standard emergency water pouches. It is triple purified using reverse osmosis and UV sterilization, kosher certified, and made in the USA.

Is pouch water environmentally friendly?
Foil pouches create far less volume than bottled water and reduce waste during storage rotation cycles. The 5-year shelf life can lower disposal and replenishment frequency for large emergency programs compared to annual bottled water rotation.

Who uses emergency water pouches?
Emergency water pouches are used by school districts, government agencies, military installations, senior care facilities, response teams, disaster relief organizations, and individual preparedness planners. Mainstay's easy-open design makes it particularly well suited for programs distributing water to elderly individuals, children, and others who may have difficulty opening standard emergency pouches.

What is the difference between SOS, Mayday, Datrex, and Mainstay pouches?
All four brands are US Coast Guard approved 4.2 oz emergency water pouches with 5-year shelf lives, made in the USA. Mainstay is distinguished by its easy-open pouch design, triple purification process, and kosher certification. SOS is also kosher certified and the only brand available as individual units and in multiple pack sizes. Mayday and Datrex carry additional SOLAS international maritime approval. Mainstay cases contain 60 pouches with a pallet of 5,040.

Can these be purchased in bulk?
Yes. Cases of 60 and pallets of 5,040 pouches are available. Purchase orders and tax-exempt orders accepted. Contact us at 888.733.7245 or quotes@moreprepared.com for volume pricing.

How should damaged pouches be handled?
Discard any pouch that shows signs of damage, leaking, or puncture. Do not consume water from a compromised pouch.
