Select the clearest available freshwater source whenever possible to support better flow and longer filter life.

Portable Collection Filter Into the Included Cup

The outlet hose can be secured to the supplied clean-water cup with the included clip for controlled water collection.

Water Intake Floating Pre-Filter System

The intake floater helps position the inlet away from heavy sediment at the bottom of the water source.

Best For Camping, Hiking, Travel and Emergencies

Suitable for outdoor recreation, preparedness kits, remote travel, and temporary freshwater filtration situations.

Freshwater use only: Do not use this filter with seawater, chemically contaminated water, carbonated drinks, sugary liquids, alcohol, milk, juice, flavored beverages, or other non-water liquids.

3-Stage Filtration System

02

Manual Pumping, Multi-Layer Filtration

Each movement of the pump handle draws freshwater through the external pre-filter and internal composite cartridge. The filter materials work together to help reduce sediment, suspended particles, chlorine, unpleasant taste, and odor before water reaches the outlet hose.

01

PP Cotton Pre-Filtration

Helps intercept sediment, soil, rust particles, and other suspended material before water reaches the finer filtration layers.

Sediment Control Particle Capture
02

Activated Carbon Fiber

Helps reduce chlorine, unpleasant taste, and odor to improve the overall drinking experience.

Chlorine Reduction Taste Improvement Odor Reduction
03

0.01 μm Hollow Fiber UF Membrane

Provides high-precision physical filtration through a compact hollow fiber ultrafiltration membrane.

0.01 μm UF Membrane Physical Filtration
Use the external pre-filter whenever possible: Keeping the pre-filter attached helps reduce the amount of visible debris entering the main cartridge. This can support steadier flow and help protect the internal filtration materials.

Replacement Filters & Components

03

Replace the Filtration Components, Not the Entire System

The internal filter cartridge and external pre-filter can be replaced separately. This allows continued use of the pump body, handle, hoses, connectors, floater, and clean-water cup.

Main Replacement Filter K8007 Replacement Filter Cartridge

The main cartridge combines PP cotton, activated carbon fiber, and a hollow fiber UF membrane. It installs inside the K8187 pump filter body and provides the system’s primary filtration performance.

PP Cotton Carbon Fiber 0.01 μm UF Up to 3,000 L
Compatible with K8187
Replace when: the rated capacity is reached, water flow remains slow after maintenance, taste or odor changes, or the cartridge shows signs of damage.
Water Intake Protection Replacement External Pre-Filter

The pre-filter attaches to the longer inlet hose and helps intercept larger debris and suspended material before source water enters the main filter cartridge.

External Intake Pre-Filtration Sediment Control Replaceable Part
Designed for the K8187 Pump Filter
Clean or replace when: visible debris accumulates, the material becomes damaged, or water intake remains restricted after cleaning.
Replacement reminder: Water quality and sediment levels vary by location. Do not rely only on the maximum liter rating. Inspect the filter components regularly and replace them earlier when condition, flow, taste, or odor indicates that replacement is needed.

Key Product Indicators

04
Maximum Flow Rate Up to 1,400 ml/min

Actual flow may vary depending on pump speed, source water quality, filter condition, hose position, and sediment level.

Rated Filter Capacity Up to 3,000 L / 793 Gallons

Actual filter life depends on source water quality, sediment level, maintenance, and frequency of use.

Filtration Method Manual Hand-Pump Operation

Repeated movement of the handle draws source water through the filtration system and directs filtered water through the outlet.

Main Filter Structure Replaceable Composite Cartridge

The internal cartridge combines PP cotton, activated carbon fiber, and hollow fiber ultrafiltration materials.

External Protection Replaceable Pre-Filter

The intake pre-filter helps reduce larger debris before water enters the primary filter cartridge.

System Type Portable Non-Electric Filter

Designed for situations where electrical power, charging, and fixed water connections are unavailable.

Hose Configuration Separate Inlet and Outlet Hoses

The longer hose draws untreated water into the system, while the shorter hose directs filtered water into a clean container.

Storage Shelf Time Up to 5 Years Before Use

Store unused components in a clean, dry, cool, and ventilated place away from direct sunlight and corrosive substances.

Care & Use Notes

05
01
Choose Clear Freshwater

Avoid heavily muddy water whenever another source is available. High sediment levels may reduce flow and shorten filter life.

02
Keep Clean and Dirty Parts Separate

Do not allow the outlet hose, clean-water cup, or water outlet to contact untreated water or dirty surfaces.

03
Do Not Use Detergent on the Filter

Do not clean the cartridge with soap, bleach, solvents, chemical cleaners, or abrasive materials.

04
Do Not Filter Non-Water Liquids

Carbonated, acidic, sugary, flavored, or alcoholic liquids may damage the filtration materials and affect performance.

05
Release a Stiff Handle Carefully

If the handle becomes stiff after storage, gently rotate it from side to side, pull upward, and pump several times.

06
Check the Pre-Filter When Flow Slows

Inspect and clean the external pre-filter when pumping becomes more difficult or water intake becomes noticeably slower.

07
Remove Residual Water

After each use, drain the hoses, cup, pre-filter, pump body, and cartridge as thoroughly as possible.

08
Dry Before Long-Term Storage

Allow washable components to air-dry in a clean, ventilated area before packing the system away.

09
Protect the UF Membrane

Avoid sharp impacts, freezing conditions, excessive heat, or handling that could damage the hollow fiber membrane.

10
Replace the Main Filter on Time

Replace the cartridge at its rated capacity, or earlier when flow, taste, odor, or physical condition indicates replacement.

11
Inspect Hoses and Connections

Check the hoses, connectors, seals, floater, clip, and pre-filter for looseness, wear, or damage before outdoor use.

12
Avoid Hazardous Water Sources

The filter is not designed to make seawater or water affected by fuels, industrial chemicals, or hazardous contamination drinkable.

Cold-weather warning: Do not allow a wet hollow fiber filter to freeze. Water trapped inside the membrane may expand during freezing and damage the filtration structure.

01

First-Time Assembly & Setup

Connect the inlet hose, pre-filter, outlet hose and collection cup before operating the pump for the first time.

1
Attach the floater to the inlet hose

Install the floater on the longer inlet hose. Position it so the intake remains below the water surface while staying away from heavy sediment at the bottom.

2
Connect the external pre-filter

Secure the replaceable pre-filter to the end of the longer inlet hose and confirm that the connection is tight.

3
Connect the inlet hose to the pump

Insert the opposite end of the longer hose into the water inlet near the lower part of the pump filter body.

4
Attach the clean-water outlet hose

Connect the shorter hose to the filtered-water outlet near the upper section of the pump body.

5
Secure the outlet hose to the cup

Use the included clip to hold the outlet hose above the supplied clean-water cup or another clean collection container.

6
Check all connections

Confirm that the hoses, pre-filter, main cartridge and collection container are correctly positioned before pumping.

First-use reminder: Pump and discard the initial filtered water until the flow appears clear and consistent.
02

Pumping, Collection & After-Use Care

Follow these steps when filtering freshwater and preparing the system for storage after outdoor use.

1
Choose the clearest available freshwater

Select clear stream, river, lake, spring or well water whenever possible. Avoid heavily muddy water and visible chemical contamination.

2
Place the pre-filter in the water

Submerge the pre-filter and inlet below the surface. Use the floater to help keep the intake away from bottom sediment.

3
Keep the collection side clean

Place the outlet hose and clean-water cup on a stable surface. Do not allow them to contact untreated water, soil or dirty equipment.

4
Operate the pump with steady strokes

Raise and lower the handle repeatedly at a controlled pace until filtered water flows steadily through the outlet hose.

5
Drain residual water after use

Remove the pre-filter from the source, empty the hoses and pump out as much remaining water as possible.

6
Clean and air-dry the components

Rinse washable external parts with clean water and allow the hoses, cup, pre-filter and pump components to dry in a clean, cool and ventilated place.

If the handle feels stiff after storage: Gently rotate the handle from side to side before pulling upward. Do not use excessive force or tools that may damage the pump mechanism.

Important Use Notes

Help protect the pump, filter cartridge and UF membrane
01 Freshwater Only

03 No Detergent on the Filter

Do not clean the cartridge with soap, bleach, solvents, corrosive cleaners or abrasive materials.

04 Protect Against Freezing

Do not allow a wet hollow fiber filter to freeze. Frozen residual water may damage the internal UF membrane.

05 Separate Clean and Untreated Parts

Prevent the outlet hose, filtered-water connection and collection cup from touching untreated water or contaminated surfaces.

06 Check the Pre-Filter When Flow Slows

Sediment on the pre-filter may restrict intake. Inspect and clean or replace the component when necessary.

07 Replace the Cartridge on Time

Replace the K8007 cartridge at its rated capacity, or earlier when flow remains slow, taste changes or damage is visible.

Very short lived filter that got plugged up fast

If ZERO stars was an option I'd give it a ZERO . . . . The pump filtered the first gallon of a clear-stream water just fine. For gallons 2-3 the flow became slow. By the 4th gallon the flow was 1/10th of the original. The pump never go to the 5th gallon. It just stopped filtering. On the 5th day of my hike I switched to my original filter which worked well for the last 4 years.

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.

No replacement parts to be found

Realize that you cannot purchase replacement parts/filters. None can be found on their website. Looks like it was meant to be disposable define and used to cost fifteen dollars.

Filter life depends on your water source and how often you use it. Contact support@purewell.com with your setup and we will recommend the right replacement schedule.

Water filter

Admittedly, the filter isn't the most convenient to use, but it is an essential item in emergency situations. What��s wrong with it? Well, pretty much everything right from the start. Try collecting and filtering water from an open source, and you��ll realize just how awkward it is��even though they didn't skimp on the hoses. After all, it��s the hoses that give you the maneuverability and convenience you need.

Thanks for putting it to the test outdoors �� if it did not perform the way you expected on your water source, contact support@purewell.com and we will help you pick the right setup.

Failed in the feild

Personally bad and had me come home early from my wild camping trip. Have 1 seal missing from the pump side and the filter is getting shut off by pressure from the pump so not getting much water. Bench test at home went well but rubbish in the feild. The bag was a plastic bag not the one shown. It pumps ok but gonna try and find a better internal filter.

Sorry it arrived damaged �� that is not the standard we hold ourselves to. Contact support@purewell.com with a photo and we will send a replacement or arrange a refund right away.

Filter scheint nur f��r geringe Wassermengen geeignet.

Keine Ahnung was mit dem Filter nicht stimmt. Nach etwa 100 l fast klares Regenwasser ist er so schwerg?ngig, da? er unbrauchbar ist. Vermutlich ist das Filter schon verstopft. Leicht Verf?rbungen vom Regenwasser konnte der Filter auch von Anfang an nicht beseitigen. Filter scheint nur f��r geringe Wassermengen geeignet.

Thank you for flagging this �� that is not the experience we want you to have. Please contact support@purewell.com and our team will make it right.

Not ideal
