TYPE OF PURIFIER
This is a portable UV water purifier. The Freedom is the smallest and lightest of the models.
USB rechargeable and comes with a USB cable and an AC adapter.
The Freedom model uses instant-on technology. It is activated simply by placing it in water and turns off when disinfection is completed.
FOR WHAT CIRCUMSTANCES
For travel, outdoors and emergency preparedness – in situations where you will be using water that has not been treated.
Intended for clear water. Significant discoloration or particulate matter can reduce effectiveness. If needed, you can prefilter with a coffee filter or bandana to remove sediment, or allow very fine sediment to settle on the bottom of your vessel.
WHAT IS ELIMINATED?
- 99.9999% virus
- 99.9999% bacteria
- 99.9999% protozoa
This includes cryptosporidium and giardia, and travel pathogens that cause diarrhea, dysentery, hepatitiis and polio. Also effective on disaster risks that cause cholera and other water-borne illnesses.
Extensive testing has proven SteriPEN to be safe and effective, eliminating over 99.9% of bacteria, viruses and protozoa that cause water-borne illness. SteriPEN has earned the Water Quality Association’s Gold Seal, certifying its effectiveness.
HOW DO THEY WORK?
You put the lamp in water and stir gently.
Ultraviolet (UV) is a long-proven technology for water purification / disinfection. UV light is short wave, which is invisible, high energy light. These purifiers use the UV-C spectrum that destroys the DNA of microbes in seconds. Microbes are rendered harmless. They can’t make you sick or reproduce.
There is a visible blue light included so you know your purifier is working.
The Freedom model uses instant-on technology, turning on your lamp when you submerge it. (No activation button needed.) There are built-in controls for temperature and operation time. After the appropriate number of seconds, it turns itself off.
The Freedom purifies 16 ounces per treatment in 48 seconds.
COMPARISON TO OTHER TYPES OF FILTRATION
These handheld UV units are water purifiers, not filters. They work through disinfection by UV light, working on bacteria, viruses and protozoa. They are not intended for cleaning municipal water, but for untreated water.
(Many of the products we sell are filters, designed to remove all kinds of contaminants. Other filters chemically alter contaminants, and render them inert through ionic exchange and other processes including magentic attraction and adsorption.)
We do not sell any filters or purifiers that add anything harmful to the water.
WHAT IS INCLUDED?
- Built-in rechargeable battery
- LED flashlight function
- USB cable
- AC Adapter with USA prongs
- Autotimer built in
- Neoprene carrying case
FREQUENTLY ASKED QUESTIONS
Is the UV light dangerous?
All SteriPEN models are equipped with water sensors that prevent them from being used unless the lamp is under water. Drinking containers made from glass, ceramic, metal and nearly all plastics block UV-C transmission. When a SteriPEN lamp is in a drinking vessel, the UV light is well contained.
There are very few materials that are transparent to UV-C light. These include optical grade quartz (which the lamp material is made of) and a few fluoropolyers in the Teflon family.
Will the water taste be effected?
How fast does it work?
There is a built-in microcomputer that controls the operation time. Normally 48 seconds. It also has temperature sensors.
Will it work in very cold temperatures?
Yes, they have been successfully used on Kilmanjaro and Everest. If the temp is below freezing, put the lamp in your interior pocket for a little while to warm it.
