MSR Hyperflow and Nalgene

Filtering water in the everglades is necessary as there are all sorts of bugs and floaties out there and it's also necessary to prefilter too as there are many sources of water that may damage normal sawyer-type hollow fiber filters stranding you in a place without water and few options other than getting off trail and genuine risk to human life.
Drink unfiltered water at your own peril.
Lot's of hikers have their own way to collect and filter water in Florida. Many use their Gatorade bottle to collect dirty water and filter that through a coffee filter into smartwater bottle. Some will filter that water into a clear bottle and some will drink directly from the filter. I'm not a fan of the later due to the possibility of cross contamination.

After my latest experience I have a new plan.

STEP 1: tie my sil-bucket to a piece of cordage. Put a rock in the bucket and toss it into the water. Pull it out and find a spot away from the waters edge.
This bucket weighs practically nothing carries plenty of water and gets you away from the waters edge where it might be dangerous.

STEP 2: At this point it might seem like a good idea to camel up whatever water you have but it's safer to have two bottles and combine whatever you have for the moment just in case the filter malfunctions and you have to ration what you have left.

At this point put the prefilter in the bucket and start pumping. Depending on the performance of the filter your container should be filled in just a few minutes.
I like to carry two 750ml smartwater bottles but it could easily be two 1L bottles. I drink more than the 1L per 4 miles that people talk about. Water is heavy and I also like a light and small pack. (very few small packs have deep pockets for a 1L bottle.

STEP 3: camel up and repeat steps 1&2 as needed.

STEP 4: clean the filter.
Trailshot
Hyperflow

Recently I started to consider a different MSR filter, the Hyperflow.

Features that make it interesting it the size of the prefilter, the length of the hose and the wide mouth bottle top and connector for the filter. The kit is heavier than the trailshot.
I purchased a clear Nalgene so I could see how clean the filtered water is. At this point I could always decide whether or not to add Chlorine or other tabs. These bottles are considerably heavier than the smartwater and I'm also less likely to carry more than one which makes my steps above a challenge.

But some things I noticed this weekend with my Nalgene...

[1] the wide mouth is great. But when it falls over dirt is caught on the lid's grip as there is not much of a lip between the lid and the sidewall.

[2] it does not fit all pack's side pockets

[3] the lid that came with the Hyperflow is probably not meant for long term use but just the filling process or some emergency should the original break. The MSR filter door kept opening.

[4] On a multi-day hike ICE is not usually an issue but when I iced my water this weekend the bottle had lots of condensation getting my pack and gear wet... so leave the ice at home.

One piece of interesting new is that there is a 48oz Nalgene bottle that seems to stand taller and not necessarily wider but I won't know until arrives. It's also an opaque white instead of clear. The white seems to be a lighter material than the clear so that might make for a better container.

Lastly while bushcrafter's like Dave Canterbury like stainless containers so purification is through heat they do not talk about water sources in Florida or water sources with high levels of particulates. They seems to like clear running streams. Also, fire means dealing with fire season and precautions.
