Waterdrop G3P800 Reverse Osmosis System

The G3P800 is a tankless under‑sink reverse osmosis system that eliminates the bulky storage tank, freeing up cabinet space while providing on‑demand filtered water.

With a five‑stage filtration process and a high‑rejection RO membrane, the system removes up to 99% of contaminants, delivering up to 800 gallons of clean water per day. Designed for DIY installation, it includes pre‑drilled fittings and clear instructions for a hassle‑free setup.

APEC ROES-100 Essence Reverse Osmosis System

The ROES-100 is the high-output model in APEC's Essence series, a five-stage under-sink reverse osmosis system rated at 100 gallons per day. That capacity is the reason to choose it over the more common 50 GPD systems: a higher production rate means the storage tank refills faster, so a busy household is less likely to run the tank down between uses. APEC states the system removes up to 99 percent of contaminants. The five stages combine sediment and carbon pre-filtration, the RO membrane itself and a final polishing stage, which is the standard under-sink RO arrangement. APEC sells a deep catalogue around it: replacement filter sets, tanks, pumps, leak detectors, housings and faucets, plus alternative configurations including tankless, countertop, UV and pH-remineralising variants.

Designed for easy DIY installation, the RCC7 includes a clear housing for filter changes, a dedicated faucet, and a storage tank that provides up to 50 gallons of purified water. It’s NSF certified and comes with a limited lifetime warranty on the tank and a 1‑year warranty on the filters and membrane.
