G'day Amy,

The Guardian Purifier filter should not be dried out at all.
Check out MSR's article explaining why here.

G'day Floyd,

Great question, but unfortunately not.  I've tried this one out in store and the MSR Guardian is too wide to screw onto any jerry can.
You can absolutely hold it inplace over the jerry can mouth, but it won't screw on or attach in any way.

G'day David,

The thread on this water purifier is fairly universal and should suit most wide mouth style bottles. We know it fits the Nalgene Wide Mouth Bottles and all of the current model Camelbak Chute, Eddy, Carry Cap and Chute Mag bottles. Outside of these brands that we carry it's hard to know for sure what will fit. 

G'day Lyn,

You can download the user manual directly on the MSR website, they also provide lots of great FAQs if there is anything you need to know. I hope that helps.

G'day Lea,

Yes the Guardian Water Filter is designed to connect to the Dromeday Bags.

G'day Adriane,

The purifier doesn't have a shelf life/expiration date, however, it is recommended that you sterilize the purifier before or after long term storage of the unit - there are instructions for this in the manual.

Hi Blair, there is a replacement available which we would likely be able to get but we don't carry it as a core line. The existing filter lasts 10,000 litres of water so they are not an item in heavy demand.

G'day Eddy,

Great question! I've had a chat with the supplier and the Guardian doesn't have a carbon filter as it has the Advanced Hollow Fibre as its filter which treats up to 10,000 litres of water and requires no backflushing or scrubbing! The MSR Miniworks EX microfilter has the carbon component if you were needing this for your travels.

G'day Mark,

I've just tested this out and the water outlet nipple on the Guardian Water Purifier is a little smaller than Camelbak Tubing. So you could use it, but it won't create a seal, so you'd have to find a way to secure it to the tubing, or hold it while pumping.

G'day Janet,

The MSR Guardian won't remove salt from water, a filter with a carbon element such as Lifestraw Go 2 may help improve the taste.
