The Water Purifier Bottle is when compared with various water bottles with filters on Amazon. The Brita, Berkley, Camelbak and LifeStraw Go are in contrast to the Water Purifier Bottle by Survival Hax.
All 5 bottles have quality filters and therefore are BPA Free. 3 out from the 5 can purify volatile organic compounds. 2 out of the 5 can filter more than 200 gallons. Simply one of them has filtration capabilities of .1 microns.
The Lifestraw go and Survival Hax bottles have removable survival water filtration straws which can be back washed.
For office use the Berkley, Brita, and Camelbak are best. They have better water flow compared to other 2 bottles. For camping, prepping, backpacking, and bug out bags, The Lifestraw and Survival Hax are superior.
