There are viruses that can infect bacteria, plant cells and animal cells. They basically use the cell's biochemistry to replicate. Viruses can only replicate by infecting a host cell. I hope maybe in a year or so MSR will find a way of using the same filter technology but in a unit half the weight and size of the Guardian - a lower price would be good too! That could then be a great filter for solo backpackers, even if the flow rate is half that of the current Guardian. So some advantages to the Guardian, some disadvantages - cost not being the least of them. One of the YouTube reviews also mentions it being very slow (he was filling another water bottle from the TT), the Guardian purifies water rather quickly. MSR claim the Guardian is freeze resistant, which I believe is a big problem on activated carbon filters like the TT. Other people note the problem with the bottles leaking around the cap - again not what you want if the water is really dodgy. I would have thought at least drying it off with a towel would be a good idea? The reviews on .uk are mainly good but someone mentioned theirs failed rather quickly (blocked up maybe?) and needed replacing. The vids of people sticking the bottle into a lake, putting the filter cap on and immediately drinking from it strikes me as a good chance of cross contamination, with water on the outside of the bottle running down to the cap which you drink from. Having watched a couple of YouTube videos of people reviewing the TT, I also thought to be super careful you would probably want some other bottle to scoop water up with and decant into the travel tap bottle. It also has the prefilter on the tube and the backwash meaning it could deal with muddy water that Travel Tap says you need to avoid (or prefilter in some way). Indeed if I have a go at the Pennine Way this summer, I might well invest in one.īut as you asked, firstly the tube on the Guardian means you can put it into tiny or very shallow water sources that you can't fill a bottle from. So again, the Travel Tap looks great - it might well be a better solution for a solo backpacker than the Guardian being a lot lighter besides anything else.

I dropped one star for the weight and the concern about breaking the ceramic filter so if that doesn't bother you then boost it to 5 stars.This feels a bit like you want one of the early Naughties internet-fights-to-the-death type threads but I haven't used the travel tap, so I can't review it in comparison. I'd seriously consider buying this again but I know filter technology is always progressing but I do rate this filter highly, four star in fact. The filter itself is heavy but overall I don't see it as excessive.I could shed a few lbs to make up for the extra weight of the filter. I do worry about cracking the cermanic filter from something like a fall or dropping it but you could carry a spare filter.

It does seem like they put some thought into how the filter will be used and how to design it so to minimize contamination risk from unfiltered water. I like the fact it screws directly onto the Nalgene bottles and the clean outlet from the filter is mostly kept protected from any exterior contaminants. I find the pump rate acceptable and only slows when filtering water with a lot of sediment. The water I've filtered has tasted great and I've had no ill effects from it. I've done a few hiking trips with this filter and I really like it, the more I use I the more I like it.
