What it does: Makes and sells high-end home water-filtration systems, primarily under the Aquasana brand.
Why it's growing: Recent studies showing that chloroform and other carcinogens are absorbed and inhaled in the shower have driven sales of Aquasana shower filters. Sun Water also makes the Beauty Water shower filter, a private label for celebrity hairstylist Jonathan Antin. Marketed for its ability to soften hair and skin, the filter has been selling well on QVC and in the Sephora and Victoria's Secret catalogs.
