How to use

Purify water in 4 steps

Simple, repeatable and ready anywhere. Always follow the dosing printed on your pack.

1
Start with clear water
Collect water from the clearest source you can. If it looks cloudy, pour it through a clean cloth or a filter first, then treat it.
2
Drop in the tablet
Add one tablet to your container, matched to the dosing printed on your pack. The 397mg tablet treats up to 4 gallons; the 49mg tablet treats 0.75 to 2 liters.
3
Wait 30 minutes
Let the tablet dissolve and work for a full 30 minutes. Give the container a gentle swirl so the water reaches the lid and threads too.
4
Drink or store
Your water is ready to drink. Pour it into clean, covered containers to keep it for later.

Safety

One tablet. Thirty minutes. Safe to drink.

Always follow the dosing instructions printed on your pack. Tablets treat microbes only: they do not remove chemicals, heavy metals or salt. Keep out of reach of children.

What it does not treat

Aquatabs disinfect. They don’t filter.

Salt Heavy metals Chemicals Sediment

For cloudy water, strain it through a clean cloth or filter first. For chemical or salt contamination, you need a different source.

Pair with a filter or Mylar-stored backup water for full coverage.

FAQ

Questions before you buy?

Call or text a real person, 11am–5pm CST: 213-523-3329

How long do I wait before drinking?

Wait a full 30 minutes after the tablet is added. Cold or very cloudy water may need a bit more care, so check the dosing on your pack.

What is the difference between the 397mg tub and the 49mg 100-pack?

The 397mg tablet is the larger size, treating up to 4 gallons at a time, and comes in a compact tub. The 49mg tablet treats 0.75 to 2 liters, so it suits single bottles and packs, and each tablet is sealed in its own foil strip.

Can it remove heavy metals or chemicals?

No. Aquatabs disinfect water by treating bacteria, viruses and cysts. They do not remove heavy metals, chemicals, salt or sediment. For cloudy water, strain or filter it first.

Can I use it in salt water?

No. Aquatabs are made for fresh water sources and do not remove salt.

Do they have an expiration date?

Yes. Check the date printed on your pack and keep tablets sealed in a cool, dry place for the longest shelf life.

Will it taste like iodine?

No. Aquatabs avoid the harsh iodine taste, and the water has no bad color or odor.
