KATADYN BeFree AC | 1.0 L Rock Blue

2 liters per minute

Take the 1L collapsible water filter bag into the mountains, and bring it along for daily life and travels. The 0.1-micron hollow fiber membrane handles filtration, while the replaceable activated carbon improves taste and reduces chlorine odor. The manufacturer specifies a maximum flow rate; however, activated carbon can restrict flow, and actual performance will vary based on water quality and filter condition.

plan how you will stay hydrated.

To get started, remember these three steps

The following is an operation summary; please continue to refer to the original manufacturer's manual for initial use, cleaning, and storage.

01

先濾掉 1 L 水

首次使用先過濾並倒掉 1 L 水。打開或重新裝入活性碳後，也要依說明書沖洗。
02

選水源，再裝水

選擇可取得的較佳清澈淡水，避開滯水及人畜密集活動水域。取水時，讓吸嘴與出水端保持乾淨。
03

旋緊，輕擠補水

裝妥濾芯、旋緊瓶蓋，打開翻蓋後輕擠飲用。需要清潔濾膜時依原廠方式搖晃或在水中擺動，不用水柱直沖。

Easy to carry and convenient to take care of.

For daily use and travel, I want to use a collapsible water bottle to stay hydrated and improve the taste of chlorine.

These situations require separate arrangements.

FAQ

What can the BeFree AC 1.0L Slate Blue filter out?

The manufacturer lists the 0.1 micron hollow fiber stage as effective against bacteria, protozoa and microplastics; the activated carbon improves taste and reduces odor and chlorine. It does not remove viruses, and it is not a seawater desalination device.

Can the activated carbon in the BeFree AC 1.0L Slate Blue handle pesticides or heavy metals?

Not recommended for water that may be chemically contaminated. The manufacturer only says the activated carbon improves taste and reduces odor and chlorine, so removal of pesticides or heavy metals cannot be assumed; use a reliable drinking water source instead.

Will the BeFree AC 1.0L Slate Blue always deliver 2 L per minute?

No. 2 L/min is the manufacturer's maximum flow rate; actual flow depends on water quality and the condition of the cartridge, and the dedicated manual notes that the activated carbon limits the flow.

Do I replace both cartridges of the BeFree AC 1.0L Slate Blue at the same time?

No, they are counted separately. The hollow fiber membrane is rated at up to 1,000 L depending on water quality and condition; the activated carbon is replaced after 200 L or 3 months after first use, whichever comes first. If the membrane is damaged, stop using it even before it reaches its rated volume.

Can I use the BeFree AC 1.0L Slate Blue without the activated carbon?

Yes. The manufacturer's design allows leaving out the activated carbon; the EZ-Clean membrane must still be installed correctly and kept intact. Without the carbon you lose its taste improvement and chlorine reduction.

Can I clean the BeFree AC 1.0L Slate Blue membrane directly in a stream?

Fill the flask with water, reattach the cartridge and shake it vigorously, or hold the cartridge and swish it in water; untreated source water can be used. The outlet (mouthpiece) must not touch untreated water; keep it clean afterward. Hold the flask end lightly while swishing; do not squeeze the filter itself. Do not blast it with running water or touch or squeeze the hollow fibers with tools or fingers. For the full procedure, follow the manufacturer's manual.

Do I still need drinking water in my emergency kit with the BeFree AC 1.0L Slate Blue?

Yes. A filter does not make water and cannot handle every contaminant; prepare drinking water and a water plan first, and treat the filter as a supplement when a suitable fresh water source is available.

Where can I check the manufacturer's specifications and care instructions for the BeFree AC 1.0L Slate Blue?

The Slate Blue model is 8021402. The fact sheet lists capacity, weight and cartridge data; for use, integrity checks and storage, see the manufacturer's BeFree AC manual.
