Purewell Outdoor Water Filter – 0.01 μm ultra-fine filter removes 99.99% of bacteria & heavy metals | 1500L filter capacity | Portable drinking water filter with neck strap for survival & outdoor

1500 L capacity per 1 piece (filter) gives you 1000 days of clean drinking water if you dink 1.5 L per day (a very realistic scenario in survival conditions). How much is 1000 days? It is exactly 2 years and 9 months of clean, drinking water. So, if you purchase a bulk of 4 filters, you have: 1000 days for a family of 4 or 2000 days (5 years 6 months) for a couple or 4000 days (11 years just for yourself). Please, mind that the label says the shelf-life of this filter is 5 years. I am pretty sure it still functions after date of expiry but perhaps its efficiency may be impaired. This is an amazing product for the price if you thin about it, what it provides you with. VALUE 4 MONEY! Money well-spent. I do recommend this product.

The order was despatched as was stated,was delivered wrapped well and in perfect condition.I cannot give the product a review as I have not opened them,they are in case of emergency but I'm sure they will be fine,they look well made.

Great for its price! Its easy to use and works it still tastes like a bit of mud but it's still drinkable the only issue is when you suck it out directly it takes a while and hurts my lips but you can squeeze it out with an old coke bottle or a water pouch! comes with instructions and is very easy to use! Great quality and is half the price of the original brand life straw!

I bought 3. I can say they are a useful size for carrying, using and storing. I've used one, the others are spares. Used when drinking from streams and springs in the UK Peak District. Very drinkable although the water still retains a `peaty' flavour due to the local geography. No internal issues so must conclude they work! I'd suggest every hiker carrys one. You never know when you might need one and it doesn't add to your walking load or take up space.

Great at what they do

Packed in 2s, good to have for an emergency

Nice and handy to have just in case. Have not used yet

very handy good price

Sicuramente farà il suo lavoro di purificazione poi si vedrà quando sarà il momento di usarla..la delusione è la foto ingannevole,l'ho acquistata perché dalla foto pensavo fossero 3 in quanto volevo regarne 1 ad un mio parente e con sorpresa è stata consegnata senza avvisarmi il giorno prima col rischio che qualcuno la potesse rubare..quindi mezzo soddisfatto..

Wat zijn sterren waard? Ze zijn prima verpakt voor langere opslag. Ik hoop ze echter nooit te hoeven gebruiken, maar het is wel een geruststellend idee de sloot te kunnen leeg slobberen in noodgeval.

Schnell geliefert! Da die für den Notfall sind habe ich die nicht geöffnet, sehen aber aus wie auf dem Foto.

Je trouve pas assez puissant en matiere de filtrage, mais peut dépanné

Pas enconbrant , pratique pour rando
