bought this as a back up. you never know when you will need an xtra.
Great filter, but watch the silt.
- Familiarity: I've put it through the wringer
After 2 years I just ordered this replacement after I ruined the cartridge that came with my MSR Sweetwater. I never had any trouble filtering water from mountain lakes and streams, even some places that were a bit sketchy came out clear and tasteless. However on our last outing it rained and turned the clear creek a creamy coffee color with silt. This quickly clogged the filter beyond cleaning. MSR makes an external SiltStopper filter but backcountry doesn't carry it.
Overpriced, but the best
I'm glad I got a replacement before they decide to stop making these. Sweetwater system has been an integral part of my pack for years, and I don't plan on changing that anytime soon. Not sure why theses filters have to be so dang pricey (i.e. HALF the price of the whole thing), but I suppose it's a priceless piece of gear in the end.
Keep A Spare on Hand
I believe 200 gallon cartridge life is a bit of a stretch, but it's close. You can extend the life by routine brushing until the inner matrix is exposed by being worn away, then replace. Routine brushing also increases flow rate. It's not necessary to carry a replacement unless the water quality dictates it or you're traveling to a 3rd world country & be gone for awhile, but keep an extra @ home just to be safe.

MSR vs Guardian - are these sweetwater units the same thing except for color? ie do the replacements for each work with the other?
Is one better than the other?
I have the original too. Yes, the parts and filters are interchangable.

I have just purchased a replacement cartrige for my purifier. My old cartrige has the "in" port nipple on the cartrige but the new cartrige has none. Does part of the old cartrige have to be removed and placed into the new cartige, and if so, how does this come off? I have about a 25 year system.
sounds like your older system isnt the same. the MSR version of the sweetwater (& I think the older Sweetwater Guardian is the same) has the input nipple on bottom of the red pump cylinder that screws inside the cartridge - it then appears exposed underneath the unit to connect to the "in" hose

sweetwater filter sprays water where the pump shaft (clear tube) exits from the very top. I noticed small pieces of beige gasket material when this happened. Is this internal seal servicable? Looks like the top is glued on to the threaded housing.
The top pump seal/gasket has been compromised however this doesn't effect the water being filtered. It's still filtering like it should. Don't try to service the unit on your own but rather explain your situation to the store where you purchased it & they should replace the unit for you. Mine did the exact same thing & the entire unit was replaced.

I have a MSR Sweetwater filter and it is leaking at the top where the pump protrudes. After I opened it up, i found that the filter was cracked the whole length. Was this the reason for the leakage? Or is it some other problem. Thanks
your filter is probably so dirty that water cant pass through the filter. there is a relief valve at the top of the filter that the water will leak out of. you just need to replace your cartridge.
Before replacing it, take a stiff toothbrush and scrub the inside really well and see if that improves it. On longer trips I always take a toothbrush for the pump, just in case the 'leaking' becomes too disruptive.
Brush the inside of the cartridge first to see if cleaning eliminates leaking but most likely anytime your filter leaks @ the top, the cartridge element/membrane has been compromised. This is the built-in fail safe that Sweetwater originally designed into the filter to visibly display the need for replacement.

will this filter work in my Sweetwater Guardian?
Yes it will
