About this item

  • AUTHORITATIVE CERTIFICATION: The Purewell Water Filter Straw is a certified survival essential, rigorously tested and approved by SGS and TÜV (Report No. ASH15-005515-01). This portable personal water filter is a must-have piece of emergency equipment for a wide range of activities, including camping, hiking, climbing, hunting, trekking, backpacking, biking, boating, RV travel, and wilderness adventures.
  • 5-STAGE FILTRATION SYSTEM: Our advanced outdoor water purifier employs a comprehensive 5-stage process. Featuring a hollow fiber ultrafiltration membrane, coconut shell activated carbon, mesh plugs, and double-layer medical-grade PP cotton, it effectively removes up to 99.9999% of bacteria, parasites, microplastics, odors, residual chlorine, and other organic matter. Please note: It does not reduce the TDS value, ensuring essential minerals remain for balanced and healthy hydration.
  • SUPERIOR FILTRATION ACCURACY: As a key piece of survival gear, this purifier boasts a 0.01-micron pore size for exceptional filtration, significantly finer than many other filters (0.1 microns). Despite this superior accuracy, it maintains an optimal flow rate of 550 mL/min, allowing for quick and easy hydration on the go.
  • HIGH CAPACITY & PORTABLE DESIGN: This durable survival water filter provides a long lifespan of up to 1,500 liters of clean water. The included 22 cm flexible hose allows for comfortable drinking. Weighing less than 100 grams and compatible with any standard 28mm threaded bottle, it is the ultimate portable solution, easily fitting in your hand, pocket, or emergency kit.
  • PREMIUM, FOOD-GRADE MATERIALS: Crafted from robust, BPA-free food-grade plastic, this filter straw is built to last. Its versatile design features multiple connection modes, allowing it to attach easily to standard water softener bags or disposable water bottles. This ensures a reliable source of safe drinking water anywhere, making it an indispensable tool for everyday hiking and travel, as well as critical emergency survival situations.

  • 2
    Add Washer and Gasket Place the washer and gasket in the correct position.
  • 3

  • 3

  • 2
    Secure the Filters Use the filter washer and wing nut to hold each core filter in place.
  • 3
    Check Stability Make sure each core filter is firmly installed before adding water.

How It Works

How the Filter System Works

Water is added to the upper chamber and moves through the center filter by gravity. After filtration, water collects in the lower chamber and is ready to dispense from the spigot.

1. Fill the Upper Chamber

Add water to the top chamber. The system works without electricity, plumbing, or pressure.

2. Gravity Moves Water Through the Filter

Water naturally flows downward through the center filter element, where the filtration process takes place.

3. Filtered Water Collects Below

After passing through the filter, water collects in the lower chamber for storage and daily use.

4. Dispense When Needed

Open the spigot to pour filtered water for drinking, cooking, or everyday hydration.

Filter Replacement

Filter Replacement Guide

Replacing filters on time helps your filtration system keep working properly. It also helps maintain water flow, drinking water taste, and everyday use confidence.

!
Track Usage Time & Filter Life

Filter life may vary by water quality, usage frequency, and total water volume filtered.

Rated Filter Life Reached

Replace the filters when they reach the rated lifespan listed for your filter model.

Water Flow Becomes Slower

If filtering takes much longer than usual, clean or replace the filters as needed.

Taste or Odor Returns

If unwanted taste or smell becomes noticeable again, it may be time to replace the filters.

Source Water Matters

Rain, river, stream, or well water may shorten filter life compared with regular tap water.

What to Check Before Replacing Filters
Confirm Compatibility

Choose filters that match your filtration system, filter series, and setup.

Prepare New Filters

Prime, rinse, or flush new filters according to the product instructions.

Check Seals & Washers

Make sure washers, seals, and threaded parts are installed correctly.

Clean the System

Empty and clean the upper and lower chambers before installing new filters.

Replace Sets Together

If your system uses paired filters, replace matching filters together when needed.

Record the Date

Write down the replacement date and set a reminder based on your usage.

Used once

Filter was slow and barely dispensed water after one filter. Backwashed and cleaned and still took excessive amount of time to fill water bottles.

Sorry the flow is slower than expected �� filters usually speed back up after a quick back-flush, and heavily silted water can clog them sooner. Contact support@purewell.com and we will help you get it running at full speed.

These are a necessity.

I want to have these on hand just in case of power outage. I haven��t tried them so I pray they work.

Thanks a lot for the great review! Stories like yours keep us motivated. Cheers to great-tasting water!

Avoid buying this brand, get one that attaches to a bottle making it easier for a child to use.

I won't purchase this item again because of the need to having to purchase an additional piece in order to hook up to a bottle making it easier for a child to use. I wasted my money buying this brand.

Sorry for the trouble �� this is not the quality we stand behind. Contact support@purewell.com and we will resolve it for you right away.

En mi opini��n no funciona

Yo pas�� agua por ese filtro y cuando lo med�� result�� que ciado el agua pas�� , ten��a m��s metales que antes de filtrarla , ciertamente no me atrevo a usarlo, y lo med�� con mi medidor de agua y el agua la extraje de mi grifo y media menos del grifo 184 y cuando el agua pasa por el filtro cojio un nivel alto de TDS , superior a 200 algo que no debe de suceder , deber��a estar al 000

Thanks for the note on filtration performance �� the specialty filters target fluoride, chlorine and PFAS specifically. Contact support@purewell.com and we will recommend the right combination for your water.
