A filtered water bottle has filters that remove microplastics, bacteria, sediment and harmful contaminants like lead and pesticides from water. To find the best filtered water bottle, I visited a freshwater source in Southern California's Santa Monica Mountains. I tested the bottles in a tiny pool of water that looked the least stagnant. After filling the bottles, I drank the water and poured some out to see how clean it looked. Once I drank and examined the water from each filtered water bottl

The deadline to pay your taxes is days away. If your tax bill isn't paid in full by April 15, you may receive a letter from the IRS saying your taxes are overdue. That can lead to interest, fees and in extreme cases, possible jail time. I've been an accountant for more than a decade and I can say that jail time is rarely the first step the Internal Revenue Service takes if you owe money.

I'm addicted to blow-dry brushes, full stop. I've been styling my hair almost exclusively with a blow-dry brush of some kind for the past two years, ranging from the high-end Dyson to the affordable Revlon Volumizer. All of these brushes are pretty similar in the way they dry your hair: hot air blasts out around the bristles, allowing you to style your hair while it dries. While it works well enough, it does result in some frizz and is sometimes less polished than you'd hope. Overall, they're al

Big-ticket electronics like TVs and soundbars may be at the front of the line.
