Which removes more, the iSpring or the Practical Survival?

The iSpring claims more: up to 99.9999% bacteria plus virus and lead reduction through its electro-positive membrane. The Practical Survival claims over 99.99% bacteria only.

The Practical Survival, by far. Each filter is rated for 1,800 gallons versus 132 gallons per iSpring element, and the pack includes 5 filters.

Is the iSpring worth the extra money?

Yes if you need virus and lead protection or better-tasting water. If you only need bacteria removal for emergencies, the Practical Survival pack is cheaper and filters more water.

Can I use either on a water bottle?

The iSpring fits standard 28 mm soda bottles and includes a silicone hose. Practical Survival lists no bottle adapter, so plan to drink directly from the straw.

Which is better for a bug-out bag?

Practical Survival: lighter, 5 filters, a 6-year shelf life and a flushing plunger. The iSpring is the better pick if your bag is for international travel where viruses and lead are a concern.

Do either work on salty or very dirty water?

No. Practical Survival caps max TDS at 500, and the iSpring is a straw filter, not a desalinator. Both suit freshwater sources, not seawater.
