What is a Water Filter Gravity Bag?

Have you tried a portable water filter gravity bag? If you’re into preparing for the unexpected, then chances are you have a survival water filter in your emergency supplies. However, gravity bags are not as well known but after using one, I believe every prepper should have one in their bug out bag or stashed with their emergency supplies!

What is a water filter gravity bag? Many survival water filters use a straw or small hand pump to suck water from a stream, river, or lake through a filter into clean drinking water. With a water filter gravity bag, a person would use it to collect water from a water source and then hang it so that the water filter is lower than the bag of dirty water. The weight of the dirty water automatically pushes the water through the straw filter and produces cleaner drinking water. The bag is perfect for hiking, backpacking, camping and in disaster preparedness. 

So why is this a great product to have in a bug out bag? Its ability to filter 1 gallon of water in several minutes using gravity. The bag also makes it far easier to collect a lot of water at once. It’s compact, lightweight, and doesn’t require any specific skills to use, making it suitable for general family use.

The price for these bags ranges from $39.95 – $109.95 depending on the brand name. It’s important to pay close attention to how many liters the gravity bag can carry, 2-4 liters seems to be the common range. 

HydroBlu Go Flow Water Filter Gravity Bag

I chose to review the HydroBlu Water Filter Gravity Bag because it holds 10 liters and currently sells at a lower price point. HydroBlu also makes good quality products.

What the kit includes:

• (1) 10 Liter Water Gravity Bag
• (1) 35 inch Detachable Hose 
• (1) Water Filter Straw
• (1) Hose Clamp to stop water flow
• (1) Removable Carrying Strap with Hook Clamps
• (1)  Small Bag that fits all the above items

How to Use a Water Filter Gravity Bag

Step 1 – Fill up the gravity bag with water.

Step 2 – Roll and clamp the open end of the gravity bag closed.

Step 3 – Attach the shoulder strap and hang the gravity bag from a tree.

Step 4 – Attach the water filter straw to the opened end of the hose.

Step 5 – Close the white clamp that’s attached to the hose so water won’t be able to come through.

Step 6 – Attach the other end of the hose to the gravity bag.

Step 7 – Open the white clamp when you are ready for filtered water to come out of the water filter straw.

Cons: (I’m trying to be objective but it’s hard to come up with cons)

• Other gravity bag kits weigh less, mostly because they only hold 2 liters of water instead of 10 liters but for some people, every ounce added to a bug out bag matters.
• Some gravity bags come with a tree strap for hanging from the trunk of a tree instead of a shoulder strap which can be used to hang from a branch of a tree. Personally, I prefer the shoulder strap.
• Like most filters that hold water – it can freeze – so it’s just something to be mindful of. 

Before heading out to the next hiking, camping or hunting trip, get a Water Gravity Bag with Filter and experience the difference. Make sure it has a large carrying capacity to ensure you won’t keep on rushing back to the nearest water source for more drinking water giving you peace of mind to enjoy the adventure. You also reduce the baggage of carrying safe drinking water from home.
