Filter Systems

3-Stage whole-house and 6-Stage under-sink reverse osmosis. Engineered for Florida water.

3-Stage Whole-House System (WH300)

Whole-home filtration using sediment, carbon, and Filtersorb SP3 salt-free descaler. Each stage is chosen from your water test to target specific contaminants.

Oasis Purely Water WH300 3-stage whole-house water filter system
WH300 whole-house system — sediment, catalytic carbon, Filtersorb SP3.

Three stages of filtration

  • Stage 1 — Sediment: Dual-gradient polypropylene filter media reduces dirt, rust, and sediment. High flow rate and long-lasting capacity to protect downstream stages.
  • Stage 2 — Catalytic carbon: Highly activated catalytic carbon cartridge reduces heavy metals, sulfur odors, chlorine taste, and chemical impurities including VOCs, TTHMs, and PFAS.
  • Stage 3 — Filtersorb SP3: Specialty ion-exchange resin removes PFAS (including PFOA and PFOS), nitrates, sulfates, arsenic (arsenate), chromium-6, cyanide, radium, uranium, and strontium. This stage removes most of the toxic chemicals in your water for whole-home safety.

6-Stage Under-Sink Reverse Osmosis (RO100MP)

Under-sink reverse osmosis with sediment, GAC carbon, carbon block, RO membrane, Mineral-PLUS remineralizing alkaline media, and post-carbon polishing. Delivers clearer, crisper water at one dedicated faucet or through the Titan water selector at your existing faucet.

Oasis Purely Water RO100MP 6-stage under-sink reverse osmosis system
RO100MP 6-stage reverse osmosis — drinking, cooking, ice, and more.

Ideal for drinking water, ice cubes, cooking and food prep, humidifiers, aquariums, pets, steamers, and baby formula. Remineralization media adds back beneficial minerals and improves taste and alkalinity of RO-filtered water.

Six stages of filtration

  • Stage 1: Reduces particulate matter (dirt, rust, sediment) to protect the RO membrane and system.
  • Stage 2: Coconut shell GAC (granular activated carbon) reduces chlorine, taste, odor, and cloudiness.
  • Stage 3: Solid carbon block cartridge with NSF-certified coconut shell PAC (powder activated carbon) for chloramines and other chemicals.
  • Stage 4: Polyamide thin-film composite RO membrane — filters to 0.0001 micron at 75 GPD for fast production.
  • Stage 5: Mineral-PLUS remineralizing beads replace minerals lost during RO, improving taste and pH.
  • Stage 6: Coconut shell carbon polish reduces residual impurities for better-tasting, better-smelling water.

Titan water selector: Use your existing faucet with no new holes in the counter. A push-button under the counter edge delivers clean RO water to your glass.
