Product Description

water filter straw blue CHE -A+-1 1464

What is the shelf life of it?

Our personal water filter straw will be indefinite if unused and stored in a protected environment, moderate temperature, low ozone, etc.

Can be connected gravity bags and disposable water bottles?

Our upgraded straw can not only connect disposable water bottles of 28mm threading as squeezable water filtration system but also as a replacement filter of different gravity systems. Of course, it also applies to our 6L gravity system "B08ZYMXLMH".

What is different from the upgrade of the straw water filter and before?

The upgrade water filter has a larger filtration capacity of 5,000 L (Can only filter 1,500 liters before), and the water flow rate is getting faster.

How to drink filtering water quickly?

1) When Water Filter is dry, stand it up in drinking water for 1-2 mins or rinse the water filter straw under the tap from the "mouthpiece" side, until the inside is wet; 2) After each use, backwash by clean water, and vertical placement to dry.

How to extend the straw water filter lifetime?

We suggest that you always use the best fresh water source to backwash the straw filter after each use. Note: Be sure to remember dry then storage and doesn't work for seawater.

Does the job- perfect fit
5 Stars
Does the job- perfect fit
I go camping alot and sometimes it becomes a pain to have to boil water when you want clean drinking water when you run out of any water you might of brought with you so I bought these for the convenience. We are also “preppers” in a sense. Nothing extreme but we like to have extra of everything just in case because of the way things have been lately with food and fuel or even any natural disasters that can occur. But I bought them originally for camping and have actually used them. It was great because when the kids come camping they don’t have the patience to wait for us to boil some water and then actually let the water cool off so we bought these for each of our kids. They each have one in their bag and it was pretty simple to use. The 5 step filtration system gives me that piece of mind that when it’s being used that we are drinking clean water. I like that both ends of the straw are removable so that I can clean the filter to help it last longer. But it’s a great quality product to add to your camping/survival kits.

I love the fact you can attach it to a water bottle (I tried it on a 16.9 FL Oz water) it would make collecting water super easy when camping/hiking etc. It has a convenient lanyard so you can hang it around your neck or wherever really. Great product for the decent price point.

These are amazing. I have many of these packs in my bugout bags and prepping boxes. I like tonuse these though when I'm out and about with my water bottles. The water tastes much better and I feel that I'm getting a cleaner resort of water. The use of these are super easy. These are something that is more of an extra assurance in filtered water when you're not near a filtered water station. We love our filters at home for our kitchen, but these provide and amazing resource when traveling or just away from the luxury of filtered stations. Stay safe.
