Models LA 1400S and LA 2000S ceiling- or wall-mount commercial-grade air cleaners offer a capacity of 800 to 2,100 cfm and gather over 95 percent of particulate down to 0.01 micron, the company states. Each unit has a variable-speed control. Cabinets are available in white, black, or wood grain. All power supplies are wired with solid-state components instead of circuit boards. There are no soldered wires. The lightweight cells weigh 13 pounds and will fit in a standard dishwasher, the manufacturer says. These models replace Models LA 1400 and LA 2000.
