* Flow rate will vary based on water quality and filter maintenance. Back-flushing is recommended every few days, or more frequently in areas with very poor water quality.

How do I backflush the filter?

To backflush the filter, use the included 16 ounce water pouch or a clean water container (like a Smartwater bottle). Fill the clean water container with clean water and connect to the output end. Disconnect any tube or containers from the input end. Then squeeze the clean water container to force clean water back through the filter and out the input end. This will flush any debris within the filter. Back-flushing is recommended every few days, or more frequently in areas with very poor water quality. 

How do I improve my filter flow rate?

Since the system relies on gravity to filter water, hang the 6L water bladder as high as you can above the water output container.

Also, make sure to purge air out of the hose. To do this, let a bit of water flow through the hose before clamping the hose and attaching the actual filter. This will ensure all air inside the hose is removed.

Finally, air can also get trapped within the filter and reduce the flow rate. If you're seeing slow flow rates, give the bladder a squeeze (with the top rolled closed) to push water into the filter and clear out any trapped air.

Can the filter be used on it's own, like a straw filter?

Yes, you can definitely use the filter like a straw. Simply connect the hose to the input end and submerge in the water source. You can then drink from the output end. To help with this, you might want to cut a short section of hose to attach to the output end. This will help make drinking easier and more comfortable.

Can the filter be used with squeeze bags, like the CNOC VECTO Bags?

Yes, the filter can be combined with 28mm thread bags on the input end to create a squeeze filter if needed.

How do I remove kinks from the hose?

The hose may arrive with kinks from being stored folded up. Simply run some hot water over the hose for 20-30 seconds to soften it and remove any kinks.

How do I store the system at home?

Let the filter and bladder dry completely before putting away. If you want to wash the bladder, use a mild soap and flush with clean water. Keep the system in a dry place in the included mesh storage sack.

Super Fast Passive Filter!!

I've tried a number of different backpacking filters, both passive (gravity-fed) and active, such as a pump filter. Many passive filters slow down quite quickly and have to be flushed often. I took this filter for it's maiden voyage on a hut trip weekend with 17 people and it filtered water for half the weekend before needing one little flush, then continuing to filter. Excellent product at the right price point.

6L gravity water filter system

I bought this to try out over small 1L bags which can take time to fill.
I love this system. It's easy to scoop up water from a brook ,river or lake .with one scoop you can snag 6L of water and go.
I like the straps to help carry to camp, it also helps to hang in a tree and fill as you need. The Paria water filter works fine as well ..I have always used sawyer. But I've filtered only maybe 19-20 liters so far but no issues. Back flush is simple.. easy to clean the bag when home.
I really recommend this product ..it's not only good ,it can be half the cost of other brands that you are basically paying for the name .

Needs improvement

Just ok. Took a chance on this filter because of the price and I have other Paria products that are great. Used it on a 9 day float trip on cold, clear lakes and rivers in AK (virtually no silt and nutrient poor). Found that for every 6L filtered, we had to back flush the filter once or twice to keep water flowing at a reasonable pace which seems excessive compared to other similar filters I've used on other trips with poorer water quality. The strap attachment is also cheap and annoying to clip around a tree or branch when the bag is full. Otherwise, it was easy to use, and when it was working, did provide fine filtered water.
