Universal Filter System Designed for Wide-Mouth HydroFlask, IronFlask and ThermoFlask Water Bottles - Sport Cap Lid, Replacement Straws and Carbon Activated Cartridges (3), FT052X

I attached the filter to my COLDEST water bottle. I love that I can drink tap water that taste as good as VOSS water anywhere.

I put ice in this one day and there is still ice 24 hours later even after being in the car over night

I tried it out with a 32 oz hydro flask. With the filter part you only need 1-2 inches of the actual straw. We have city water and definitely smells of chlorine. Seemed to take most the taste away. Haven’t tired long term yet. I will update after I use it for a while.

This is a simple charcoal filter. Comes with a universal sip cap, fits hydroflask as well as Nalgene bottles. Two extra filters and two long straws comes with fklter. If using with 32oz or smaller bottles you end up with 4 straws. No instruction were provided in the package. Be sure to wash/flush the charcoal fklter before use, to get rid of any dust particles.

It looks like a useful product, but it was irritating, not to find any specific information about the filter, lifespan, the proper assembly method, or any details about the filter's operation. You were left to figure it out for yourself, and even though it isn't that challenging, you would think that a decent company would pay the money to include instructions, or at least print some on the back of the card packaging which is completely blank. 它看起来像是一个有用的产品，但令人恼火的是，没有找到有关过滤器、使用寿命、正确组装方法或有关过滤器操作的任何详细信息的任何具体信息。你必须自己弄清楚，尽管这并不是那么具有挑战性，但你会认为一家体面的公司会花钱包含说明，或者至少在卡片包装的背面打印一些说明，这完全是空白的。
