What are the differences between a water filtration system with two stages and one that has a reverse osmosis system with four or three?
These are the most common questions we receive. There are many systems on the market, and many of them are just marketing-speak. Five-stage water filters, seven-stage reverse-osmosis systems sound better than two-stage or three-stage systems. However, once you know what contaminants you want to remove, you can begin to calculate how many stages your water filter unit will require. You’ll quickly realize that five, six, and seven stage systems are not necessary for purifying water. Three options are available for water filtration systems: Sediment & Carbon (2-stage), reverse osmosis (3 stages RO), and reverse osmosis/deionization (4 stage RODI). These three options are practical and affordable. All of this will be explained below.
How do you start? How do you intend to filter the water? You may want your drinking water to taste better. This would be possible with a simple water filtration system such as the Pure Blue H2O Reverse Osmosis Water Filtration Unit. The compact filter measures 6″Lx4″ Dx13″H and can be installed under a sink to dispense water through the included chrome faucet. This design is common in countertop water filtration units. Our two-stage unit can be mounted under a sink and dispenses water through the included, easy-to-install chrome faucet. This compact design is ideal for small spaces thanks to the pivoting cartridge heads. Our 5-micron Sediment cartridge is the first stage. This traps sediment and other particles that can affect taste and appearance. The Carbon filter cartridge is the second stage. Activated carbon reduces chlorine levels by 99 percent, eliminates odors, and improves water taste. The new Twist-In triple-sealed Twist design allows for quick and easy replacement of filter cartridges. This compact design is ideal for small spaces thanks to the pivoting cartridge heads. It is important to have a storage tank in order to store high-quality water.
What about reverse osmosis? There are many Reverse Osmosis water filter options on the market, making it difficult for consumers to choose the right one for them. This is a basic overview of how reverse osmosis systems work. The membrane is the heart of any reverse osmosis system. This membrane is usually made from a semi-permeable thin-film composite (TFC) material that can be degraded by chloride. To protect the carbon filter, it is recommended to use a sediment prefilter cartridge filter. These three components are required to complete all stages of reverse osmosis systems.
STAGE 1: Sediment filter to remove silt, dirt, and rust from your water. This protects the Carbon filter.
STAGE 2: Carbon filter with activated carbon to remove chlorine/or chloramines from the water and condition it prior to the reverse-osmosis membrane. Also protects the RO membrane.
STAGE 3: Reverse Osmosis Membrane is used to remove organic and inorganic compounds such as Fluoride. It also reduces impurities known by Total Dissolved Solids(TDS) from water down to 1/10,000 (0.0001), which reduces arsenic and lead, parasitic cysts, and copper.
STAGE 4: Color Changing Resin deionization Filter to remove any remaining total dissolved solids from membrane filtered water. The water will usually retain a small amount (usually 1%) of total dissolved substances (TDS) after it has been filtered through the membrane. It is crucial to eliminate any remaining TDS in aquarium water applications. The water is filtered through a resin that has been charged with Cation- and Anion resins (H+, OH-). The resin will absorb the TDS and change its color as it exhausts. Once all resin has changed colors, it’s time to replace the DI filter. This gives you an indication of when to change media.
