LifeStraw Peak Series Solo Bundle vs LifeStraw Personal Water Filter Straw

Both are LifeStraw membrane filters with the same 0.2-micron protection against bacteria, parasites and microplastics. The Peak Series Solo is the better everyday and travel pick: it screws onto standard 28mm bottles, flows at about 3L/min, and each filter is rated for 2,000 liters. The Personal Straw is the better emergency and backup pick: it filters up to 4,000 liters, has unlimited shelf life when unused, and weighs slightly less. Owners rate the straw 4.9 out of 5 and praise its reliability and neutral taste; the main trade-off is that you drink directly through it rather than filtering into a bottle.

• Choose the Peak Series Solo Bundle if you want to filter into or through a standard water bottle, want a faster flow, and like having three filters to split between a pack, a car and a travel kit.
• Choose the Personal Water Filter Straw if you want one compact filter with double the rated capacity and unlimited shelf life for a go-bag, hiking pack or emergency kit.
