Congratulations on your purchase of the PortaWell™ portable water filtration system. This patented system is made in the USA and is designed to provide an affordable and efficient method for filtering potentially harmful contaminants (both biological and chemical) from a non-potable water source in an emergency or off-grid camping situation to make it suitable for human consumption.
PortaWell is shipped with three general purpose filters: Sediment for the reduction of particulate such as silt and sand, ceramic for reduction of biologics such as bacteria and cysts (i.e., giardia) and Activated Carbon Block for reduction of chlorine and volatile organic chemicals (i.e., herbicides, pesticides).
The PortaWell™ design provides the following:
- It is compact and portable (weighs less than 10 lbs.)
- It is designed to fit in a standard 5-gallon dual purpose bucket for ease of storage or transport.
- It uses standard commercially available 10-inch filters (filters can be tailored to specific contaminant needing removal).
- It provides two-stage filtration for effective removal of most common water borne contaminants.
- A small 12-volt battery (optional) that is rated a minimum of 7 to 10 Amp hour can be used to power the PortaWell. A 30-to-50-watt solar panel (optional) can be used to recharge the battery or extend the battery pumping time.
- It effortlessly provides up to 1 gallon per minute flow rate allowing a larger volume of water to be processed than alternative gravity fed or mechanically pumped systems.
- Use good judgement when selecting a water source to be filtered and always seek the best fresh water source available. Avoid water sources that are obviously contaminated with chemicals, heavy sediment, algae bloom, and/or biological waste (animal or human) products. If viral contamination of the water is suspected, consider post treatment of the water with a chlorine solution and let sit for 30 minutes.
- The pump is not designed for continuous duty operation. To extend the life of the pump, best practice is to operate for up to 30 minutes and rest for 5 minutes. If the ambient temperature is above 90 degrees F, reduce the operating time and extend the rest times accordingly. Always shield the pump from direct sunlight when operating to help minimize pump overheating.
- Do not store the PortaWell™ in below freezing conditions unless the system has been winterized to remove all water from the filter housings, transfer tubes and pump.
- Do not store the PortaWell™ in direct sunlight. This is to prevent deterioration of the filter housing.
- Do not pump anything other than water through the PortaWell™ .
- Do not power the PortaWell™ with any source other than 12 volts. Solar panel (if used) should be connected to a battery and battery to the PortaWell™. A 110 volt to 12-volt (5 amp) transformer (optional) may be used to power the PortaWell™.
- Do not operate the pump without the screen inlet filter. This is to prevent debris from entering the pump.
- Do not store the PortaWell™ with water in the filter housings for more than 72 hours. This is to prevent any algae buildup.
- Do not use with a damaged or cracked filter cartridge. Use care in handling the ceramic filter as it is fragile and easily broken.
Setup - Filter Installation
The PortaWell is shipped with a ceramic filter to reduce pathogenic bacteria and cysts, a carbon block filter to reduce organic chemicals and chlorine and a sediment prefilter.
- Wash hands before handling filters.
- Installation of OBE (Open Both Ends) filters:
- Remove filter housing by unscrewing the transparent canister bowl from the top and remove from the PortaWell. Take care to not lose or damage the bowl O-ring.
- Remove the filter from the packaging and place (with washers) into the bowl and over the bottom sealing protrusion. Orientation of the OBE filter does not matter as there is no top or bottom. The Doulton Ceramic filter (if supplied) must be installed with the open end at the top.
- Reinstall the bowl to the housing top. Move the bowl around until the top of the filter engages the top protrusion making sure the sealing washer is still intact. (If bowl will screw into the housing top, the filter is securely installed).
- Hand tighten the bowl to the housing. A small amount of plumber’s silicon grease on o rings and gaskets ensures a secure fit.
- Remove PortaWell from the 5-gallon bucket and place on a stable level surface.
- Attach the clear plastic inlet tubing to the inlet barb of the pump. Tubing is attached by pressing the tubing onto the barb. The inlet tubing has the screen filter on one end. A clamp is not necessary because this is a low-pressure fitting.
- Attach the clear plastic outlet tubing to the outlet barb of the filter housing. Tubing is attached by pressing the tubing onto the barb. A clamp is not necessary because this is a low-pressure fitting. Note: Use caution to keep the outlet tubing clean and free of any contamination as this is used to transfer the clean, filtered water to the potable water storage container. Do not interchange the inlet and outlet tubing.
- Place the end of the outlet tubing into a clean container. Best practice is to use a food grade rated container that has a lid to store and transport the filtered water.
- Place the end of the inlet tube (end with the small screen filter) into the non-potable water source. Best practice is to bucket the water from the source (stream, river, lake, pond etc.,) and then pump from the bucket.
- Connect the power pigtail to the pump.
- When ready to begin pumping, affix the alligator clamps to the battery taking care to connect red clamp to the positive battery terminal and black clamp to the negative battery terminal and switch the PortaWell to the on position.
- When starting and stopping the pump, switch PortaWell to off rather than disconnecting the waterproof connector.
Note: Maximum operating pressure of the pump is 45 psi at which point an internal limit switch will stop the pump. If pump fails to run continuously when switched on, it is usually because the ceramic filter has been plugged and needs to be cleaned before proceeding.
When the PortaWell™ will not be operated for more than 72 hours, it is important to remove the water from the filter housings and filters to prevent possible algae growth.
- Run the pump to expel as much water as possible from the housing. (Pump can be run dry with no damage)
- Remove the housings and the filters from the PortaWell.
- Empty the filter housings of any residual water. Take care to not let any unfiltered water in the housing come in contact with the inside (clean side) of the filter.
- Shake any residual water from the water filters.
- Air dry the housings and filters for 24 hours or until all residual water is evaporated.
- Remove the tubing between the outlet of the pump and the inlet filter housing to drain any excess water.
- Reinstall filters and housings.
Note: Care must be taken when removing the ceramic filter for storage that the inside of the filter (clean side) does not become cross contaminated with water from the outside (unfiltered side). Best practice is to rinse the housings and ceramic filter in a 1% chlorine bleach solution for 10 minutes before air drying and storage. 2 tablespoons bleach per 1-quart water will give a 1000+ ppm disinfecting solution

Selection of Filter and Filter Sequence
Note: This table is for information only and it is the responsibility of the user to select the appropriate water source and filter setup as some water sources may have additional contaminants than shown below.
– Bacteria, Cysts (>.5 to 1-micron diameter)
– Virus (< .5-micron diameter)
- Organic Chemical
– Total Organic Carbon, Industrial Solvents,
– Aromatic compounds
– Algae color and cyanobacteria toxins
- Organic Plant
– Algae, Moss, plant/animal decay
- Inorganic Chemicals
– Dirt, silt, sand
Treatment Purpose/Filter sequence
- Chlorination Treatment (used to kill when high levels of pathogenic bacteria and virus are present)
- Sediment Filter (Used to remove particulate >1 microns)
- Ceramic Filter (Used to remove .5 to 1-micron biologic contaminants including giardia, crypto and bacteria)
- Carbon Block Filter (Used to reduce volatile organic chemicals, toxins, and chlorine)
Note: The filters listed above do not remove inorganic dissolved solids such as magnesium and calcium (hard water). They also do not remove salt from seawater.
Water Contamination Filter Selection Guide
In cases where water source is heavily laden with multiple contaminants, it may be necessary to filter the water twice, changing filter types between treatments based on the table above.
Note: Best practice is to always place the carbon block filter after the ceramic filter. This prevents the carbon filter from becoming potentially contaminated and prevents premature fouling of the ceramic filter due to shedding of small carbon particles during the initial phase of filtration.
