Review: Wanted to Love - I was really excited to finally find a filter for my hydro flask. Super easy to use and nice concept. I even enjoyed the multiple lid options. However, it is not easy to drink out of. It is almost like drink through a half clogged straw. Review: Works great! Used for trip to Bali - Used for trip to Bali due to groundwater contamination concerns. Never got sick. Used with our Takeya water bottles from Costco, and the lids fit perfectly! Straw can be a little hard to suck from at times. Very happy with purchase! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07K2K6MLQ | | Brand | Epic Water Filters | | Brand Name | Epic Water Filters | | Capacity | 2 Pounds, 2.5 Pounds | | Container Type | Bottle | | Customer Reviews | 4.1 out of 5 stars 17 Reviews | | Manufacturer | Epic Water Filters | | Package Information | Bottle | | Part Number | EPC-OD-ANS-FTR-40 | | UPC | 688713576939 | ## Product Details - **Brand:** Epic Water Filters - **Capacity:** 2 Pounds, 2.5 Pounds - **Manufacturer:** Epic Water Filters - **Package Information:** Bottle - **UPC:** 688713576939 ## Images ![The Outdoor Answer | Hydro Flask Compatible Water Filter System | Filter Straw Lid Combo | American Made Nano Filter Removes 99.9999% of Fresh Water Contaminants (32 & 40 OZ) - Image 1](https://m.media-amazon.com/images/I/71OOzxyWlLL.jpg) ![The Outdoor Answer | Hydro Flask Compatible Water Filter System | Filter Straw Lid Combo | American Made Nano Filter Removes 99.9999% of Fresh Water Contaminants (32 & 40 OZ) - Image 2](https://m.media-amazon.com/images/I/8156AzpRCFL.jpg) ![The Outdoor Answer | Hydro Flask Compatible Water Filter System | Filter Straw Lid Combo | American Made Nano Filter Removes 99.9999% of Fresh Water Contaminants (32 & 40 OZ) - Image 3](https://m.media-amazon.com/images/I/91D1ZLtiyoL.jpg) ![The Outdoor Answer | Hydro Flask Compatible Water Filter System | Filter Straw Lid Combo | American Made Nano Filter Removes 99.9999% of Fresh Water Contaminants (32 & 40 OZ) - Image 4](https://m.media-amazon.com/images/I/71XqhKCKeRL.jpg) ![The Outdoor Answer | Hydro Flask Compatible Water Filter System | Filter Straw Lid Combo | American Made Nano Filter Removes 99.9999% of Fresh Water Contaminants (32 & 40 OZ) - Image 5](https://m.media-amazon.com/images/I/51y0Pyfw-DL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Wanted to Love *by R***I on November 25, 2019* I was really excited to finally find a filter for my hydro flask.
