The system uses a five-layer purification process, including:

1. Non-woven fabric – Blocks large particles and sediment.

2. UF membrane (0.1 micron) – Removes bacteria, protozoa, and microplastics.

3. Activated carbon fiber – Improves taste and removes odors.

4. Ion-exchange resin – Reduces heavy metals and harmful ions.

❓ Frequently Asked Questions

Q1: How long does the filter last?

A: The filter can purify up to 1,400 gallons (5,300 liters) of water under optimal conditions. Actual lifespan depends on water quality and frequency of use. Regular backflushing helps maintain flow and extend life.

Q2: Can I drink directly from the straw?

A: Yes! While the system is designed for gravity filtration into bottles or cups, you can also use the straw independently by attaching it to the hose or drinking straight from a water source.

Q3: Does it remove viruses?

A: The 0.1-micron filter effectively removes bacteria (like E. coli) and protozoa (like Giardia and Cryptosporidium), but it does not remove viruses. For viral protection, we recommend boiling, chemical treatment, or UV filtration in high-risk areas.

Q4: Can I use it with a dirty pond or river?

A: Yes – it's designed to handle untreated freshwater sources such as lakes, rivers, and streams. However, extremely turbid or silty water may clog the filter faster. If possible, let the sediment settle or pre-filter through a cloth.

Q5: How do I clean or backflush the filter?

A: Use the included backflush device (syringe-style). Fill it with clean water and flush through the straw in the reverse direction to remove debris and restore flow. We recommend doing this every 10–15 liters or when the flow slows down.

Q6: Is the bag durable?

A: Absolutely. The 1.5-gallon bag is made from thick, BPA-free TPU material that's resistant to punctures, tearing, and leaks. It's built to withstand tough outdoor use.
