You're choosing between two different water-filtration purchases: a compact inline filter and a protective case made for a similarly compact filter. The decision isn't which brand is better-it's whether you're missing filtration or missing protection.
Quick verdict
The Products Mini Water Filtration System is the actual filter in this pair. It's built for portable use, connecting to bottles, hydration packs, pouches, or a straw for direct drinking, and it lists for USD 23.47.
The Waterproof EVA Case for Sawyer Mini Water Filtration System is the protective half of the pair. It's a hard-shell travel case for a Sawyer Mini filter, and it lists for USD 15.98.
If you need filtered water on the go, choose the filter. If you already have a filter and need a carry shell, choose the EVA case.

Product notes
Products Mini Water Filtration System
This is the filtration tool in the comparison. It's designed for outdoor recreation, travel, and emergency preparedness, and it attaches to a drinking pouch, a standard 28 mm disposable water bottle, a hydration pack, or a straw for direct drinking. The listed capacity is 100,000 gallons, the body weighs about 41 g, and a cleaning plunger is included. Its stated removal profile targets bacteria, protozoa, and microplastics.
The limitation is that this is a filtration device, not a storage shell. The included items are the filter and the cleaning plunger, so it doesn't serve as a carry case.
Waterproof EVA Case for Sawyer Mini Water Filtration System
This case is the storage half of the head-to-head. It's made from high-quality, shockproof, waterproof, and tear-resistant EVA material, so it's meant to protect a compatible mini filter from scratches and impacts. The hard shell opens with a smooth 360-degree zipper, includes a comfortable handle for portability, and has a built-in mesh pocket for accessories. In short, it's a travel companion for a filter you already own.
The limitation is that it doesn't filter water on its own. It only makes sense after you already have a mini filter to carry.
Final choice by use case
Choose the Products Mini Water Filtration System when you need the filter itself. Choose the Waterproof EVA Case for Sawyer Mini Water Filtration System when you need a padded travel shell for a mini filter you already own. One is for producing filtered water; the other is for keeping your existing filter safe.
