Frequently Asked Questions
How do these purifiers remove contaminants and what kind of water sources are they safe for?
Each purifier uses a different method! Some, like the SteriPEN, use UV light to nuke microbes. Others, like the SimPure and Survivor Filter, use filters with tiny holes to block bacteria, protozoa, and even some viruses. The product descriptions detail what each one removes, so check that out to see which one fits the water sources you plan to use. If you use a purifier that needs clear water, maybe filter the water first to make the purifier work.
What is the filter lifespan for each product and are replacement filters available?
Filter lifespans vary. The SimPure Gravity Filter lasts for 5,000L, while the Katadyn Hiker Pro’s cartridge lasts for roughly 300 gallons. The SteriPEN is different; it’s rated for 8,000 uses of its UV lamp. Replacement filters are generally available for the filter-based systems, like the Katadyn. Check the product pages for replacement options.
Are these purifiers easy to use for someone without much outdoor experience?
Some are super simple, like the SimPure Gravity Filter – just hang it and let gravity do the work! The SteriPEN is also straightforward; just dip and stir and you’ll be good to go.. Others, like the Survivor Filter PRO and Katadyn Hiker Pro, need a bit more effort since they’re hand pumps. But overall, none require rocket science to operate!
What are the power requirements and battery life considerations for electric or UV-based purifiers?
The SteriPEN Ultra UV has a rechargeable battery and should be good for many uses. The Electric Water Purifier is solar-rechargeable, giving another option when you are outdoors. Remember temperature can mess with performance, check product details!
How do these purifiers affect the taste of the water, and do any specifically improve taste?
The SteriPEN doesn’t alter the taste since it just uses UV light. The Katadyn Hiker Pro actually improves taste because it has activated carbon. Other filter-based purifiers should remove any funky tastes from sediments or larger particles, but they don’t actively change the taste like the Katadyn does.
