KATADYN Water Purifier BeFree AC Bottle 0.7L - Sky Blue

It has a dual-layer cartridge: a 0.1 micron hollow fiber membrane removes bacteria, protozoa, cysts and microplastics, and activated carbon improves taste and reduces odors and chlorine, at up to 2 L per minute.

No. The manufacturer's manual states that the product does not remove viruses; if the water may carry viruses, treat it separately or use a reliable drinking water source.

The hollow fiber membrane cartridge lasts up to 1,000 liters and the activated carbon up to 200 liters, both depending on source water quality. The carbon also has a time limit: replace it 3 months after first use. Replace the membrane as well if the flow stays slow or stops even after cleaning.

The manufacturer's specifications list tap water and clear water as water source types, and the product description says the activated carbon improves taste and reduces odors and chlorine.

When the flow slows, fill the bottle with water, reattach the cartridge and shake it vigorously, or hold the cartridge and swish it in water to clean it; untreated source water can be used, and no backflushing or tools are needed. However, the outlet (mouthpiece) must not touch untreated water; keep it clean after cleaning. The manual recommends cleaning at least every 5 liters to extend the membrane's life; if shaking or swishing does not restore the flow, replace the EZ-Clean Membrane. The manufacturer's specifications say the cartridge can be cleaned in the field.

Yes. It is a lightweight, squeezable bottle that stands on its own, and hand squeezing speeds up the flow. It comes with a carry loop and a sealed flip cap, and the mouthpiece is a removable silicone one.

The cartridge specs are the same. The 0.7L weighs 93 g and measures 95 x 75 x 236 mm; the 0.9L weighs 104 g and measures 95 x 75 x 278 mm, making it taller and heavier.

The manufacturer's spare-parts page lists a BeFree AC Bottle replacement cartridge, BeFree AC activated carbon replacement pads (3-pack), a BeFree AC flip cap, and silicone mouthpieces (3-pack). Contact Mabu Valley for availability.

Before first use, filter and discard 1 liter of water to flush the EZ-Clean Membrane; do the same after opening the activated carbon holder or reinserting the carbon. Maintain it every 100 liters of use or before storage by following the maintenance steps in the manufacturer's manual, and let every component air dry completely before reassembling. After long-term storage, flush the system with 1 liter of filtered water to remove dust, particles and stale taste; if no water flows, fill the bottle and let it soak for at least an hour.

No. The manufacturer's manual says to filter fresh water only (untreated water from lakes, rivers, streams, wells, taps and so on), never salt or brackish water; filtering anything other than fresh water may damage or contaminate the EZ-Clean Membrane.

Not recommended for water that may be chemically contaminated. The manufacturer's fact sheet and manual describe the activated carbon as improving taste and reducing odor and chlorine; pesticides and heavy metals are not mentioned, so no removal can be assumed. Use a reliable drinking water source instead.

Per the manufacturer's manual: filter fresh water only; the product does not remove viruses; do not let the EZ-Clean Membrane freeze; do not rinse it under direct running water or touch the hollow fibers with tools or fingers; keep the outlet (mouthpiece) away from untreated water; screw the filter onto the bottle straight and tight to avoid cross-threading, which could let unfiltered water bypass the membrane, and make sure the air vent and bottle seal are tight with no unfiltered water leaking; do not use it if the membrane is damaged or contaminated; if it is dropped hard and may be damaged, follow the manufacturer's website instructions for a filter integrity test.

The fact sheet lists the flip cap, silicone mouthpiece, activated carbon, handle, EZ-Clean Membrane and bottle; the manual's parts diagram also labels an air vent and a bottle seal. The manual lists four replacement parts: the EZ-Clean Membrane, activated carbon fiber, flip cap and silicone mouthpiece, and the manufacturer's spare-parts page lists the same four types; the air vent and bottle seal are not listed as separate replacement parts.
