PurifiCup™ Portable Water Purifier (Natural Water Series)

For those who are passionate day-hikers like me, you are always looking to lighten your pack and heighten your emergency preparedness. I’ve had my eyes peeled for a portable, packable water filter that is very lightweight with a small footprint. Pump water filters work great but are somewhat bulky, taking quite a bit of valuable pack space. Enter the PurifiCup™ Portable Water Purifier just slightly larger than a soda can and weighing less than 11 ounces (305 grams) an ideal addition to any hiker’s tool belt.

Disclosure: I contacted Independence Sales & Marketing, LLC to try their PurifiCup™ Portable Water Purifier product at no cost to me. My only responsibility was an agreement to provide a product review. I was not pressured in any way to make a positive endorsement.

Product Description

The world’s first and only portable water purifier to adopt nano-silver technology, PurifiCup™ eliminates more
than 600 kinds of bacteria, providing you safe and clean drinking water worry-free. PurifiCup™ is a portable water
filtration system perfect for travelers or for outdoor enthusiasts such as hunters, hikers, campers, boaters and
anglers. It is also a necessity for any emergency preparation kit.

With PurifiCup, you can enjoy convenient drinking water on the go whether the water source is tap or a freshwater stream, waterfall, river, or lake. PurifiCup’s world-patented design uses a nano-silver membrane filter to destroy up to 99.99% of bacteria, parasites, and pathogens such as e.coli, giardia, cryptosporidia, etc. Utilizing the natural anti-bacterial and anti-fungal properties of silver, bacteria are removed from water as it is filtered through PurifiCup’s exclusive silver membrane.

There’s no need for boiling water after it is filtered and each filter provides up to 11 gallons (100-150 cups) of pure water. The PurifiCup’s absolute 1 micron filter will more consistently remove bacteria such as crypto than a nominal filter.

Exclusive 3 Stage Filter Technology

  1. Ion exchange resin: Turn hard water into soft water by removing heavy metals (lead, copper, cadmium, mercury, etc.) and calcareous (magnesium, calcium ions).
  2. Activated carbon: Remove chlorine and other organic odor including THM, organic solvent, and pesticides.
  3. Nano-silver membrane: The membrane kills 99.99% of the pathogens in natural water sources such as streams, falls, creeks, and rivers. It is located on the inlet and exit of the filter circulation channel, preventing the filter cartridge from contamination.

Both a water filter and BPA-free storage bottle, PurifiCup™ is NSF, SGS, and EEC Certified, and uses only FDA approved material. It fits easily into your carry-on, back-pack, or handbag and requires no hoses or attachments. It can also be attached to filter into a standard water bottle. The PurifiCup™ Natural Water Series comes in two different colors, green or purple.

Field Testing

Before taking the PurifiCup™ on a hike with me, I first tried it at home to learn how to use it. I’m glad I did this because I did have a couple false starts. I am a Meanderthal, after all. I used it on the water straight out of my tap and noticed leaking around the core filter housing. I thought to myself that can’t be right, and sure enough, eventually discovered I simply didn’t have the housing screwed on tightly enough. The instructions warned against applying the lids too tight, so being anal, I also didn’t get the filter housing tight enough. Once solved, the water was filtered completely leak free.

The design is really quite simple (see pictures below). It is basically a cup within a cup with the filter in between. Because there are no pumps involved in the filtration process it works via gravity and vacuum the actual filtering of the water seemed time consuming, at first. I just placed the unfiltered water container on top of the filter and it drained the 10 oz. contents in about two minutes. I tried it again and this time it took almost three minutes. After consulting with the company representative, I learned a few tricks. First, I shook the filter to make sure all air was out of it, and second, I pressed the unfiltered water container securely on the core filter housing thereby creating a vacuum. I was then able to filter 10 oz. in less than a minute (about 50 seconds). That’s more like what I had hoped for. Certainly more than acceptable.

The filtered water itself tasted remarkably fresh and pure. There was no tell-tale taste of chlorine and metals like we have become accustomed to with domestic tap water. Now that I knew how to use it, and satisfied the filtration was working properly, I was ready for a hike.

Streams and Waterfalls

Drinking from the PurifiCupI’ve been fortunate over the years to never contract giardia or any of the other nasty bacterium found in mountain water. Of course, I just don’t drink right out of the creek. I learned that lesson from the story my brother tells of battling giardia for more than a month many years ago. It’s nasty, nasty stuff. So there’s obviously a certain amount of trust you have to put in a filter when trying it on a real, live mountain stream.

The first test of the PurifiCup™ was in Matthews Creek in the Mountain Bridge Wilderness of South Carolina. I purposely picked a pool in the stream where there was algae and moss to put the filter through its paces. As with tap water at home, the PurifiCup™ filtered 10 ounces in just under a minute. The filtered water was perfectly clear. There was no green tint as there had been in the unfiltered container. Best of all, there isn’t much that is more refreshing than cold, winter mountain water… crisp and invigorating. The taste was fresh and pleasant.

Next I wanted to try lake water at valley level. The usual problem with drinking lake water is pesticides that have drained from agriculture, and herbicide runoff. My experience with the filtration was similar in time and effort, and again the water was crystal clear and clean and pleasant to the taste.

We scheduled another hike in Mountain Bridge Wilderness, this time to Falls Creek Falls. Another danger with mountain water is heavy metals, in particular mercury. When we reached the falls, I put the container cup under the cascade then attached it to the core filter housing. The water flowed clear and clean through the filter. The hike up to the falls had been very steep and tiring, so the cold water from the PurifiCup™ hit the spot. It was delightful. Later on that day when we reached another waterfall my companions asked if I would filter some water for them. They too wanted to savor some of that cold mountain freshness. I think I have a couple more fans.

Conclusions

The PurifiCup™ is easy to maintain. It doesn’t require regular cleaning or specialized detergent. Just use a regular dish soap in the sink occasionally and you’re good to go. It’s not a good idea to put the cups in the dishwasher because of the heat. It is all self-contained. All components fit within the outer cup. The core filter housing has a counter table that can be used to track the number or purifications with this filter.

Silver has been long recognized as antibacterial and anti-contaminate, and is commonly used today in the medical industry to prevent contamination to surgical equipment. It is not stimulating and does not cause allergy. It is not sensitive to PH level. The PurifiCup™ nano-silver membrane filter is a powerful guardian for the quality of drinking water.

The PurifiCup™ Portable Water Purifier (Natural Water Series) has a MSRP (Manufacturer’s Suggest Retail Price) of US$59.99. This is a relatively new product that has been on the market less than a year, so there are only a few retailers, but Independence Sales & Marketing, LLC will be gearing up their efforts very soon. You can presently purchase one at Amazon.com. There is a sister product, the PurifiCup™ Portable Tap Water Purifier that is designed for home use.

I have been quite pleased with my PurifiCup™. I would, and have, recommended it to friends. It is lightweight and compact, a nice fit in my pack. I feel more secure now that I will have the ability to create an emergency water supply should I run out or get lost or injured on the trail. If need be, the core filter housing is designed to filter water directly into generic plastic water bottles for storage. The most important thing is that I have not gotten sick from any of the tap, stream, lake or waterfall water that I have filtered through the PurifiCup™. This is a great product that I think will become very popular with the hiking community.
