Aquatabs Water Purification Tablets (397mg, 100 Pack). Water Filtration System for Camping, Boating, Emergency Water, Survival Kit, and Marine. Easy-to-Use Water Purifier Treatment.

I have 133 gallon rain barrel I use these to actually help keep the water clean. They work amazing I purchased both sizes. Just remember that how many used depends on if the water is clear or not. Every home should have these as a precaution because you never know what might happen, had a citywide water shut off. They allowed us to be able to use our rain water instead of standing in line for bottled water.

Excellent product. Safer then liquid bleach and self life is far longer if kept dry until use. We use it in the watering tanks or buckets for our animals. It works. Safe for humans too.

I put these in my RV for hikes and use when camping off-grid. They work well. Easy to carry.

Which one you get depends on what your use needs are. They are all very similar.

A person can go 3 days without water. This is one of six different ways I have to procure suitable drinking water. It comes in a small bottle. A must for every backpack.
