A-Type Portable Water Filter Straw

A compact straw-format water filter offered in Blue, Brown and Green. The supplied information describes a multi-stage design, but combines specifications for several A, B and C versions; exact filter media and verified performance for the selected A-type model must be confirmed before use.

Supplier specifications and model limits

• Listed as a seven-stage system incorporating prefiltration, iodine resin and activated-carbon components.
• The supplier gives a product-family weight range from 15 g to under 90 g, without an exact weight for this option.
• Listed water-temperature limit: below 50°C.
• Stated service capacities: Type A 1,000 L, Type B 700 L and Type C 70 L. These are unverified supplier figures, not guaranteed lifetimes.
• The source reserves heavy-metal filtration features for A-2, B-2 and C-2, and the 0.01-micron membrane specification for B-3. Neither feature is established for this listing.
• The source gives a 3–5-year period after first use, but no validated replacement schedule or storage-life evidence.

Use and care notes

The supplied directions describe drawing water through the mouthpiece, discarding the initial mouthful, clearing residual water after use, then covering and storing the device in its case. Follow the instructions supplied with the exact model; replace it if flow becomes blocked rather than assuming blockage is a reliable end-of-life indicator.

• Do not use with salt water or chemically contaminated water.
• Do not microwave.
• Choose the clearest available source water where possible; heavy sediment can clog the filter and shorten its life.

Important water-safety information

No independent test report is supplied to substantiate the original bacteria, virus, parasite or chemical-removal claims. Do not assume this straw alone makes untreated water safe to drink. Confirm the exact model's tested capabilities and follow current public-health guidance for water treatment. For general guidance, see CDC water-treatment advice for hiking, camping and travel.
