SAWYER Micro Squeeze Water Filter

Product detailed description

The Sawyer Micro Squeeze water filter comes with a new, softer 1-liter bottle, a syringe, a neoprene case, and adapters for screwing onto a PET bottle and for the outlet—which comes in handy when you want to flush the filter but don’t have the syringe with you. Simply screw a PET bottle filled with clean water onto the outlet and rinse it out. We tested the flow rates of each version for you using a one-liter bottle. We first pushed half a liter through each filter to wet the membrane and ensure the filter reached maximum performance.

Here are the results:

The most reliable system on the market

The Sawyer Micro Squeeze  is the lightest (in the SP128 version) and most versatile filtration system on the market. The filter uses hollow ceramic microfibers, whose walls form a membrane with a maximum pore size of 0.1μm.& nbsp;With a total weight of 60g (filter and 1-liter bottle) and the ability to roll it up into a small package, it takes up almost no space in your backpack.

PointONE™ technology with an absolute pore size of 0.1μm, used in Sawyer filters, guarantees the removal of 99.99999%& nbsp;all harmful bacteria (salmonella, cholera, E. coli, etc.) and parasitic protozoa (giardia and cryptosporidium), exceeding the very strict U.S. EPA and NSF standards. It also removes 100% of microplastics.

Water filtered through the Sawyer SP128/129 meets the drinking water standards applicable in the Czech Republic and the EU: (SOP 06.0.52, ČSN EN ISO 9308-1 and SOP 06.0.3, ČSN EN ISO 6222). The Sawyer SP128/129 filtration system meets EU requirements under 2008/60/EC, 95/45/EC, and 2008/84/EC. Sawyer also collaborates with the World Health Organization (WHO) and provides significant support to more than 100 nonprofit organizations in over 70 countries worldwide.

Usage

Usage is simple – fill a bottle or bag with water from a lake, stream, or river, screw the Sawyer filter onto it, and you have three options:

• Squeeze the bottle to filter the water into your clean drinking bottle or any other container.
• Drink directly from the filter—it includes a flip-top cap.
• Connect the filter’s outlet to a PET bottle using an adapter and transfer/filter the water into it.

The filter can also be used with a regular PET bottle instead of the included collapsible bottle. This is quite convenient, as it’s easier to fill a PET bottle with water and drink from it. Another excellent option is the CNOC, which has a wide mouth like a CamelBak and makes it easy to scoop water even from shallow pools. We’ve filmed this helpful video on how to use and maintain the filter in practice.

The latest SP2129 Micro includes:

• A collapsible 1.0L bottle (new, softer, with a longer lifespan).
• Sawyer PointONE™ filter with a thread for screwing onto the bottle and a flip-top cap on the outlet.
• Syringe for cleaning the filter.
• Protective neoprene case.
• Adapters for a PET bottle on the outlet.
• Adapter for connecting a hose to the inlet (if you want to use a gravity system).
• Straw.

Lifespan: filters over 378,000 liters of water!

Filter benefits:

• It is lightweight and compact.
• Compared to any competitor, it has smaller pores, ensuring higher filter efficiency.
• It has no moving parts that could break.
• No pumping required.
• Uses no chemicals, so it does not negatively affect the taste of the water.
• Higher filter flow rate than other competitors.
• For the average person, it essentially has an infinite lifespan—if the filter gets clogged and the flow rate decreases, you can easily rinse it yourself using the included syringe.
• You can drink directly from the source through it like a straw.
• The filter bottle serves as a great water reservoir; once empty, you can pack it away and it won’t take up space in your backpack like a plastic bottle.
• You can purchase filter bottles in various sizes.

Disadvantages:

• It must not freeze, as this would damage the porous membrane (this applies to virtually all porous ceramic filters).
• It is more difficult to scoop water from shallow sources into the filter bottle—for these cases, it is a good idea to carry a small cup made from a cut-off PET bottle.
• The included filter bottle has a lifespan of only a few hundred cycles (for multi-month expeditions, it’s a good idea to have a spare).

Although this is the best mechanical filtration on the market, the filter cannot remove dissolved chemicals—this requires more expensive and heavier technology, which, however, has a very limited lifespan. From Sawyer, these include foam filters Sawyer Foam Filter S1, S2, and S3 (compatible with the Micro filter). However, when used in nature, outside of industrial areas, this is not a problem. Furthermore, chemical tablets or UV water treatment do not address the issue of dissolved chemicals either.

If the filters are good enough for the World Health Organization (WHO) and its projects in developing countries, they will be good enough for our nature treks as well. "On our 4,500 km long Continental Divide Trail, we relied exclusively on the Sawyer SP129 for water; in the deserts of New Mexico and Wyoming, we filled up countless times from cattle troughs and always without any issues. The filter works perfectly."
