GRAYL UltraPress 16.9 oz Water Purifier & Filter Bottle for Hiking, Backpacking, Survival, Travel (Olive Drab)

Por suerte compré lo que yo pensé sería un filtro de repuesto pero me llegó sin el filtro que ya deporsi debería de traer me sentí un poco estafado sobre todo porque lo abrí 2 días después que pasaron los 30 para devolverlo

Works fantastic a real life saver

Overall solid quality and it seems to filter well (purely subjective as I didn’t do any water quality tests). Easy to use -separate the inner from outer container, fill the outside, loosen the cap on the inner, and then push the inside container down into the water filled litter container. If you use your body weight to push its easy. I used this to fill my other water bottles that were larger - took a few minutes but easy to do. My only suggestion is that the fill line should be in a high contrast color to see where to fill the water up to. The loop / hook on the top is fine to use to attach to a bag. The rubber grip on the bottom is a good add - keeps it from sliding around on wet rocks. Didn’t leak in my bag.

Para que llevar sistemas baratos de filtrado a la montaña para chupar de la botella si con este artículo puedes PURIFICAR el agua! Que pesa más? Si, pero por unos pocos gramos extra de peso voy más seguro que los sistemas de filtrado y eso vale la pena.
