Jason-

So what I need to do is place my HyperFlow in-line in the extended position, pumping a couple times beforehand to purge the air, and my gravity feed is good to go? This is just the bladder? No tubing, cartridge sleeve, or shut-off valve? Can I also backflush using gravity, instead of pumping? As an alternative, can my HyperFlow also be used in place of the cartridge on the AutoFlow...albeit, at the lower flow rate (ie: function, tubing diameter)? Thanks again!

Unfortunately the picture posted is the wrong one. What is pictured is the AutoFlow, so I would go to www.cascadedesigns.com/msr and check out the Hyperflow Gravity Kit. It's comprised of everything you see with the AutoFlow except the AutoFlow filter element and hose (the kit does include the tube pincher). You simply remove the prefilter from the Hyperflow and attach the Hyperflow's hose to the gray spout. Fill the 4 liter bag with water, hang, extend the Hyperflow (no need to pump), and let gravity do its thing.

The cartridge cannot be used by itself to replace the AutoFlow's filter element. You can backflush the Hyperflow by reversing the flow using gravity, but you must also reverse the orange and black 'duckbill' rubber valves as you would whenever you backflush the Hyperflow. This is not as effective FOR THE HYPERFLOW (not the AutoFlow) as the regular method of backflushing. The only way to backflush an AutoFlow is reversing the flow because of it's self-containment.

I believe this is a huge advantage of the HyperFlow over all other filters on the market because it is so easy to not only pump, but gravity feed as well. Having used it in both configurations in the field many times, I can stand by the claims it makes. Obviously as the filter is used, it will get slower, but that should be expected. (I will work with backcountry.com to get the picture changed to the actual product description...)

How does this work? I have the Hyperflow filter, but how does it connect? Also does the filter have to be backwashed every 7 L like when using the filter?

Best Answer Responded on

This gravity filter works & connects very easily. Simply fill & hang the reservoir. Connect the hose @ the bottom making sure the shut-off clamp is closed. Fill your water container on the clean side of the black filter element by opening the clamp, close when filled. Back flush only when the water flow slows down.

How much does this weigh? I'm considering buying the Hyperflow filter and getting this for trips i dont care about weight, or should i just go with the MSR Autoflow gravity filter?

Best Answer Responded on

It weighs in at about 6 oz. I've used this a few times and really like the versatility. By using the Gravity Kit, I could filter, without pumping, at about a liter and a half per minute. It made the camping chores much nicer... The benefit of going with the HyperFlow and the Gravity Kit is simply having many options. The fact that the HyperFlow will filter at 3L per minute when pumping and then having the Gravity Kit for basecamp purposes makes it very desirable. What I would recommend is carrying the pump and letting a fellow backpacker carry the gravity kit. It's also great knowing that I own a pump filter that will also gravity feed faster than most pumps!

Not the pictured product.

The picture on this Backcountry ad shows the "kit" as a hangable dirty water bladder, hoses, and a FILTER.

This picture is beyond misleading, it is in fact, a lie.

The "Hyperflow(tm) Gravity Kit" is MERELY THE BLADDER. The kit contains NO FILTER, and NO HOSES. It is unusable, by itself, for filtering water.

If Backcountry uses the picture on the product's box, each customer will see "Use With The ... Microfilter..." and would see ONLY a picture of the bladder.

Backcountry, please clarify this product page.
This product page has worked on me as a bait-n-switch.
