Tier1 delivers the all in one for RO systems with the 5 Stage Tier1 Reverse Osmosis Home Drinking Water Filtration System with 4 Reusable Glass Water Bottles. This offer includes the 5 stage reverse osmosis system with four reusable glass water bottles.

The filtration process begins with a set of sediment and activated carbon filters to remove larger particles and chlorine so the RO membrane can focus on the more nasty components and deal with less additional particle waste.

The RO membrane then rejects particles such as larger dissolved metals, minerals, and salts and sends them down the separate wastewater drain, then reduces contaminants like barium, cadmium, chromium (III and VI), copper, fluoride, lead, mercury, nitrates, nitrites, radium, selenium, and total dissolved solids (TDS). This high-quality membrane allows for only very small water molecules to pass through, which can be attributed to its high contaminant rejection abilities.

The last step of the process is a carbon post-filter that removes any residual odors and bad taste from chlorine.

Water is stored in the RO tank and available for on-demand use. Water can be dispensed via the use of the chrome faucet included with the system. This water can be additionally stored in the glass water bottles in the fridge to be kept cold or taken on the go. These bottles are reusable and BPA free, making them ideal for replacing expensive single-use plastic bottles. The system comes prepared with starting filters, membranes, housings, brackets, shut-off valve, saddle valves, tubing, fittings, standard long-reach chrome faucet, and installation instructions so you can get it installed and set up in no time. Enjoy fresh filtered water with Tier1 and protect every drop.

Reverse Osmosis

Reverse Osmosis is the process of forcing water through a semi-permeable membrane, which allows water molecules to pass, but captures water-soluble toxins, such as heavy metals, organics, bacteria, and pyrogens. Reverse Osmosis captures a significant percentage of high toxic impurities, such as asbestos, hexavalent chromium, and lead.
