Membrane Solutions Squeezable Water Filtration System - Portable

In this review of the Membrane Solutions Squeezable Water Filtration System the bottom line is simple: this kit is for hikers, campers and emergency preppers who want a lightweight, practical way to get safe drinking water on the trail. The reviewer found the pack useful because it pairs two compact 0.1 micron filter straws with six squeezable 23oz bottles, so you can draw clear water fast without carrying heavy gear. The SGS certificated filter design and the claim of up to 1,320 gallons lifespan make it an appealing backup or primary purifier for short trips.

Key Features

• Survival readiness: The kit combines two filter straws and six collapsible bottles, providing immediate tools for multi-day group outings or emergency use.
• High filtration accuracy: The 0.1 micron hollow fiber membrane removes a very high percentage of harmful particles while keeping the flow rate usable for drinking and refilling bottles.
• Long service life: Each straw is designed to deliver up to 1,320 gallons (5,000 liters) of water before replacement, extending value for frequent users.
• Compact and light: At about 7.1 in long and 1 in diameter, the straw and the 23oz collapsible bottles pack down small and add minimal weight to a backpack or survival kit.
• Five-stage filtration: The combination of a coarse screen, double-layer PP cotton, coconut shell activated carbon and ultrafiltration membranes reduces odor, chlorine and organic contaminants while improving taste.

Who It's For

This kit is best for solo hikers, small groups and family campers who need a compact, easily stowed purification solution that fits common 28mm threaded bottles and soft water pouches. It is also a sensible addition to a bug-out bag or travel pack for areas where potable water access is uncertain.

Those who need very high-volume basecamp filtration, multi-person long-term water processing, or removal of dissolved salts should look at larger gravity systems or reverse osmosis options, since this unit does not lower TDS and is optimized for portability and microbiological filtration.

Pros & Cons

Pros

• Lightweight, pocket-friendly straws and collapsible bottles that fit 28mm threads for versatile on-the-go use.
• Smaller 0.1 micron pore size for higher particulate and microbial removal than many market straws.
• Multi-stage filtration including activated carbon to improve taste and reduce odors and chlorine.

Cons

• Does not lower TDS, so dissolved minerals and salts remain in the water.
