According to a study by WaterFilterGuru.com, water bottles can be that unhygienic.

The research found reusable water bottles contain an average of 20,800,000 CFUs, or colony forming units – a calculation of the number of viable and reproducing cells in a sample.

Lanham captioned across her video, "Here's your reminder to wash your emotional support water bottle so it doesn't grow mold and make you sick."

The WaterFilterGuru.com study compared the germs on the bottle to household items, showing just how gross they can be if you're not careful.

On average, an unwashed reusable water bottle had 40,000 times the bacteria of a toilet seat, 14 times of a pet bowl and even five times the amount found on a computer mouse.
