NDūR’s One Litre Pull Top Canteen (38 oz)

“If ever I meet one of you Texas waddies who ain't drunk water from a hoofprint, I think I'll... I'll shake their hand or buy 'em a Daniel Webster cigar.” Rooster Cogburn, True Grit, 1969

They say you can live three days without water. Whether deployed, travelling or in an emergency survival situation, safe drinking water is key to survive and thrive. Consuming water saturated with microorganisms or industrial contaminants will simply make you sick and reduce your survival window. I have spent a good deal of time in SW and SE Asia working and travelling. On many trips or deployments, I would take a water filtration system and water purifying treatments. This was especially handy when in the Golden Triangle between Thailand and Burma, where there is ample water but little of it is consumable without filtration or treatment. These bulkier systems took up precious space within my loadout.That was until I stumbled upon the NDūR’s Pull Top Canteen.

It is a one litre (38 fluid ounces) squeeze bottle in the style of an old school military canteen.  A NDūR’s Advanced Filtration system is attached to the cap in line with the spout. NDūR makes similar filtration bottles in other styles and with other opening types but I selected this style for a few reasons. First, it has the most volume available in the NDūR line. Second, the shape of the bottle allows it to fit and stay in pack side pockets more secure. And, three, Pull Top bottle have less malfunctions than flip top bottles.

I prefer that the military canteen style bottle fits flatter
and therefore more secure in pouches than round bottles.

NDūR states that their filtration system:

• Removes up to 99.9999% of  viruses , bacteria  especially E-Coli 
• Removes up to 99.99% of Chromium 6, Chlorine, Lead, Mercury, Cadium , Aluminum,  Copper 
• Removes up to 99.9% of microorganisms including Giardia and Cryptosporidium

All of which are quite common contaminants in ponds, lake and streams around the world. In Canada, Guardia is particularly common. The filter has a useful lifespan of approximately 380 liters (100 gallons) before using a standard replacement filter.  That is 380 uses of the bottle!!  And, should be vacationing in Chernobyl, a CBRNe tasked trooper, or just wandering the Wastelands, NDūR has a Radiological Filter as well. It removes the same microorganisms and radiological contaminants.

We, Echo Tango 308 and I, took this canteen with us on an outing near Alquonquin Park, Ontario. The picturesque lakes and ponds in the area are populated by beavers, the cause of Guardia, as well as heavy sediment and tannic acid from fallen leaves. We found the water bottle to be an easy to use and effective water filter system.

Scoop water from an unproven source

Water on left is unfiltered straight from the lake.
Water on the right has been through
the NDūR Advanced Filtration system.

Taste Test. The filtered water tasted like bottled water.
It was clear of sediment and foul  taste or smells.
No gastroenteritis.

This squeeze bottle filtration canteen is a great piece of kit. With a long operational life span  it is simple to use and seems to do an excellent job filtering unproven water into safe drinking water. For the important role it fills, it is relatively inexpensive. Go ahead drink from that muddy hoof print now.

Take care out there.
