Aqua Classic II 100 GPD RO w/ Postfilte

The Aqua Classic II 100 GPD RO System (ACII-TLC-100) delivers high-volume reverse osmosis purification with a dedicated post-filter for a clean, polished finish. Rated at 100 gallons per day across four stages, it is built for households that draw heavily on their drinking water and want both fast tank recovery and refined taste from a compact under-sink system.

Four-stage treatment

Water passes through sediment and carbon pre-treatment to protect the RO membrane, then through the semipermeable membrane that removes a broad range of dissolved solids. A final post-filter stage polishes the stored water just before it reaches the faucet, removing any residual taste or odor it may have picked up while sitting in the tank, for a crisp, fresh result in every glass.

The Aqua Classic II platform retains the line's serviceable design, making routine cartridge changes straightforward for homeowners and installers with easy-access housings beneath the sink. The high 100 GPD membrane rating keeps the storage tank topped up even during heavy use, so there is rarely a wait, while the post-filter ensures the water tastes fresh right up to the moment it is dispensed.

To maintain consistent quality, replace the sediment, carbon, and post-filter cartridges on schedule so the membrane stays protected and the polishing stage stays effective. The post-filter in particular is what guarantees that stored water reaches the tap tasting clean, so it should not be overlooked at change time. For larger families or anyone who wants maximum output combined with a clean, finished taste, the Aqua Classic II 100 GPD with post-filter is a capable, well-balanced reverse osmosis solution.

Installed beneath the sink and tied into the cold-water line, the system delivers freshly polished RO water through its dedicated faucet, with the post-filter ensuring nothing in the tank dulls the taste. For larger families that want maximum output paired with a clean, finished flavor, the Aqua Classic II 100 GPD with post-filter is a high-capacity workhorse for the kitchen.
