At $165.99 this is the cheapest way to filter water for a whole house, and at 14.37 by 7.48 by 15.55 inches it is roughly half the height of the three-housing models, which matters in a tight utility cupboard or a crawl space. Five stages of media at 5 micron across two housings, with iron and manganese reduction claimed. The trade is capacity and depth against the larger units, and there is no published NSF/ANSI mark. Waterdrop lists $164.99 in its own spec table against the $165.99 the store charges, so check the price at checkout.
