water filters and reverse osmosis systems explanation on many stages are required
This is a common problem we often hear, there are many systems available, and unfortunately many of them are not just marketing hype designed to make the system look more beneficial. . .
The three-stage water filter, the seven-stage reverse osmosis system certainly sounds better than the first-stage water filter or the three-stage reverse osmosis system, however, in reality, this is more about the cartridges you choose to use in the system than how many stages the system has.
Here\'s a simple guide on how we can develop the best fit for your needs. Where to Start?
What do you want to remove from the water? E. g.
You may only want the water to taste better, which means reducing the box with 1 micron chlorine flavor and smell, on the other hand, you may want to remove specific contaminants such as lead or fluoride from the water, this requires a special toner cartridge.
Once you have an idea of the contaminants you want to remove from the water, you can start to understand how many stages your water purification unit needs.
We believe that in order to achieve the water quality you want, the fewer stages you have to use, the lower the cost of replacing the cartridge, and when you can get the same result with two stages, why use a system of seven stages.
There are two main options for water filtration systems, reverse osmosis or carbon filtration. This is what we think of these two options: carbon filter selection single stage or two?
In most cases, the two-stage filtration system is the best option, and the first phase is a cheap sediment filter that is only used to prevent more expensive carbon filters from being blocked by silt or sand.
If your water quality is good, you may not need to use a sediment filter.
Carbon filters are not all equal, there are many high quality cartridges that are perfect for removing chlorine, taste and smell in the water, if you want the cartridges to remove any other contaminants, you should choose a cartridge that has been certified by agencies like the NSF and say it\'s too easy for the carbon box to \"remove\" lead or cyst. The real question is what is the percentage and duration?
How about reverse osmosis?
With so many reverse osmosis water filters on the market, it is difficult for end users to understand which filter best meets their requirements.
Here\'s a basic 101 of how they work, and what everyone should pay attention to on stage, and how much is needed.
The core of each system is the membrane, in fact, it is not a reverse osmosis system if the system is not certified with the NSF 58.
Anti-permeable membranes are generally TFC that are very vulnerable to chlorine attacks, so it is necessary to remove chlorine from the water using a carbon filter, as we know, it is good practice to use cheaper sediment filters to protect carbon filters.
This leads to three phases required for most systems.
First stage sediment filter for removal of silt and sand (
Protect secondary carbon filter)
Phase 2 carbon filter for the removal of chlorine and/or chloramine (
Protective Anti-permeability film)
Why does a supplier offer a level 4 reverse osmosis system, or even a level 7 system, for organic and inorganic compounds such as fluorine removal by a stage 3 reverse osmosis membrane?
An additional stage after the Ro film is easy to explain, the water produced by the system is not very delicious and requires a toner cartridge to \"polish\" the water, in addition, the reverse osmosis water is usually kept in the tank, in the tank, it can collect smell and even harmless bacteria again. The fourth grade carbon filter will ensure that the water reaches the tap in its original state.
After the fourth stage, it becomes more difficult to put forward arguments that require more stages, in fact, reverse osmosis water is slightly acidic, so it is reasonable to use an alkaline carbon filter, but now there is a carbon filter that can alkaline the water and work on it. The only possible option after the fourth stage of \"polishing\" filtering all of this is to install a deionizer, we do not recommend the use of this method for drinking water, because if it is not maintained, it may result in the presence of traces of deionic resin.
All in all, using more stages than the water filtration system would only result in more maintenance and unnecessary costs.
