Eliminator Reverse Osmosis by SpectraPure 

Three-Stage Eliminator Reverse Osmosis Systems by SpectraPure remove damaging contaminants and salts from both city and well water. Each are a full-size, wall-mount RO water purification system. Heavy duty enough for the serious grower. 

All plants need clean water. Orchids & bonzai trees are very sensitive to water contamination. The Eliminator Series provide superior rejection of ionic, organic and particulate impurities and thus produce contaminant-free water, using 3 filtering parts:

High-silicate removal Reverse Osmosis Membranes, (1 for the MPRO-90, 2 for the MPRO-180), a high-efficiency MicroTec™ 1 micron sediment pre-filter and a high-capacity carbon block pre-filter (9000 gallon chlorine removal).

Clear filter housings help you monitor filter replacement. MPRO-90 filters 90 gallons per day. The MPRO-180 filters 180 gallons per day. Comes with filter wrench and garden hose adapter. Dimensions: 14" x 6" x 15".
