Countertop reverse osmosis removes lead and chromium-6 better than under-sink systems. HEPA filters and activated carbon target different air pollutants, potassium permanganate handles formaldehyde.

Questions this episode answers

About 20 million units sold in various channels; total AB Flex sales eventually about $300 million worldwide.

A negative-ion generator.

Pressurized holding tanks can become breeding grounds for bacteria and require annual professional sanitization; under-sink RO systems can also waste ~90% of input water (about 9 gallons wasted per 1 gallon purified).
