When the taps stop, the shops empty first

A storm, a burst main or a supply cut – and bottled water sells out in hours. Most homes have nothing in place. A filter straw is the simplest back-up you can own: small, cheap to keep, and it works with water you can actually find.

Before and after filtering

How it works – 3 steps

1. Open – take off both caps.
2. Drink – put the bottom in the water and sip. Or fill the pouch and squeeze water through into a cup.
3. Clean & store – blow air back through, flush with the syringe, cap both ends. Ready for next time.

What's in the kit

Full kit
  • 1 × filter straw (21 × 3.5 cm) with lanyard and two protective caps
  • 1 × fold-flat water pouch
  • 1 × extension tube
  • 1 × back-flush cleaning syringe
  • 1 × carabiner clip

One for every place you might need it

🏠
Home kit
For power cuts, storms and water supply problems.
🚗
Car kit
Glovebox-sized, for breakdowns and winter roads.
🎒
Day bag
Walks, picnics and camping – carry less water.

💡 Tip: the 4-Kit Family Pack covers the house, two cars and the walking bag – and is the lowest price per kit.

What it does – and doesn't – do

The straw uses a hollow-fibre membrane that physically blocks dirt, sediment and other particles as you drink. It's made for fresh water: streams, lakes, rain water and tap water.

⚠️ Please note: it does not remove viruses, chemicals, salt or heavy metals. Do not use it with seawater or water you suspect is chemically polluted. If your water company issues a boil-water notice, follow their advice.

❄️ Winter tip: a new, dry straw is fine in a cold car. Once it has been used, keep it from freezing – ice can damage the filter fibres – so dry it fully or store it indoors.

About our reviews

🟠
The reviews below were written by real customers who bought this filter straw range from our supplier's store – imported in full, including lower ratings. Most were left for the standard blue model (rated 1,500 L). This kit is the upgraded orange model – same straw-filter design, rated up to 5,000 L by the manufacturer, and supplied with the water pouch, syringe and carabiner. Each review shows which model was bought.

FAQ

Is it hard to drink through?

The first few sips take a little more effort while the filter gets wet. After that it works like a thick straw.

Can I fill a bottle with it?

Yes – fill the pouch, attach the straw and squeeze clean water into a cup or bottle.

How do I keep it clean?

After each use, blow air back through and flush with the syringe. Let it dry with the caps off, then cap both ends.

Can I use it with seawater?

No. It is for fresh water only and does not remove salt, chemicals, viruses or heavy metals.

Can I keep it in the car over winter?

Yes – keep it unused and dry in its caps. After use, dry it fully or keep it indoors, because freezing can damage a wet filter.

Good filters for water purification from bacteria (not viruses or heavy metals), convenient, compact, can be used to drink water directly from a pond, stream, etc. source, and the bottom of the filter has a thread that fits onto most standard plastic bottles; there is also a hole for a straw

It looks fine until you shine a flashlight on it and realize that the entire filter is as big as a coin. This product is dangerous to health, it is impossible for it to filter viruses and bacteria. I ordered the r

I got this item on sale for a ridiculously low price, so i'm not going to complain too much, but the quantity is nowhere near the same as other brands. I'll use it in water that seems clean but not dangerous.

The filter (hollow fiber membrane) is 3 fingers in size and of very low quality! It filters the SIM, but that doesn't mean any security at all! I did a test and it only filters slightly dirty water like from a river, and even then you have to use chlorine/boiling water with a bit more dirt, which makes the water turn yellow! There is no mechanism to improve the taste; I also put a few drops in my mouth to test, and the taste is just like dirty water! If you're going to use it seriously and your budget can't afford a better quality product. First, decant, then filter through the device, and finally boil or chlorinate.

The filter it comes with is very small, nothing like the description provided. I thought it would come with a larger internal filter due to its size, but you can see that the filter is very small. I will use it because of its price, but next time I will buy one of higher quality. I highly doubt it will filter the particles it claims to.
