Are you looking for a superior water filter to reduce the contaminants found in your tap water? Then you have come to the right place.
The fact is that with a variety of home water filtration systems on the market, you are probably confused as to which one to purchase.
What you need is a way to properly evaluate the effectiveness of a water filtering system.
There are two main ways to evaluate whether a drinking water system can be regarded as a superior water filter:
1. The system’s potential contribution to health and well-being
2. Its comparative performance and cost
Let us evaluate how carbon filtration, water distillation and reverse osmosis (arguably the three most common filtering systems) stack up against each other in regards to the above mentioned criteria.
Superior Water Filter – Potential Contribution To Well-Being
How effective are the most common water filtering units in removing the four general types of water supply contaminants?
* Micro-biological* Heavy Metals* Organic Chemicals* Inorganic chemicals
Carbon Filter: This device is excellent at removing organic chemicals from drinking water. Many of these chemicals have been linked to cancer, liver and kidney illnesses.
However, carbon filters won’t remove inorganics, heavy metals and the vast majority of microbiological contaminants.
Some carbon drinking water filters can also remove cysts such as cryptosporidium and giardia (which are micro-biological contaminants).
Unlike, a reverse osmosis unit or distiller, carbon filters don’t strip water of its beneficial mineral content. So your water ends up having a crisp taste after the other impurities have been removed.
Reverse osmosis filter: It won’t remove micro-biological contaminants but will remove organic chemicals. This system will partially remove inorganic chemicals and heavy metals.
Bear in mind that many synthetic chemicals, such as herbicides and pesticides are smaller, molecularly, than water. Therefore, a reverse osmosis filter won’t effectively remove those contaminants from your tap water.
In order for a reverse osmosis unit to be able to remove a wider range of synthetic contaminants, it needs to be used in conjunction with a carbon filter.
Reverse osmosis systems are expensive to maintain and typically waste a lot of water in order to produce 1 gallon of filtered water.
Another drawback is that this device strips water of its beneficial mineral content so the product water may end up tasting flat.
Water distillation unit with carbon filter: Can effectively remove all four categories of contaminants.
It is important to use a distiller in conjunction with a carbon filter. This is important because distillation alone can effectively remove organic chemicals that have boiling points below that of water.
A carbon filter will reduce those organic chemicals that distillation alone is unable to.
Distillers excel at removing micro-biological contaminants from drinking water. These contaminants are arguably the most harmful of the water supply contaminants.
More people globally have become sick from ingesting biological contaminants in drinking water than any other type of water contaminant.
Since a household point-of-use distiller is very effective at removing micro-biological contaminants, it is considered by some experts as a superior water filter.
Superior Water Filter – Comparitive Cost & Performance
Home water treatment systems do not have a limitless lifespan. Over their lifetimes, their effectiveness will diminish with use.
Hence in the early stages of using a new home water treatment system, it will remove the highest amount of contaminants and produce the best quality tap water. After continued use, the performance of the device and the quality of tap water will diminish.
This is a fact many water filter manufacturers fail to mention and an issue many consumers are unaware of.
When you evaluate carbon filters, distillers and reverse osmosis units in the context of cartridge replacement costs and performance, distillers come out ahead.
Both carbon water filters and reverse osmosis filtration systems use expendable internal elements and membranes that are more easily exhausted over time. Those elements must be replaced at a set time and there is a cost attached to doing so.
By comparison, water distillers produce very clean water for longer periods of time. This is because these devices use natural processes, steam and gravity, to remove drinking water contaminants. These natural processes are always on the job.
To maintain distillers is normally cheaper too. You’ll need to periodically drain the boiling chamber to remove any loose particles and liquid residue. Also, you need to clean the boiler with vinegar or a powdered descaler.
If you use a water distiller that has a carbon filter attached, you’ll need to change that filter. Carbon filters can be breathing grounds for bacteria if it is not replaced according to the manufacturer’s recommendation.
The downside with distillers is that they use electricity; the cost of producing one gallon of steam distilled water will range between 15 cents and 35 cents per gallon.
Superior Water Filter – Conclusion
On the evidence of the above, a point-of-use distiller (with carbon filter attached) is a superior water filter in terms of the range of health-damaging water supply contaminants it can remove.
However, the cost/gallon of “treated water” it can produce, can be a bit high.
If you can tolerate this and the slow rate at which a distiller produces distilled water, then this is the system for you.
A carbon filtration system and reverse osmosis filter won’t remove the range of drinking water contaminants that a distiller (with carbon filter attached) can.
Besides a point-of-use reverse osmosis filter wastes a lot of water so it is normally more costly to operate than the typical point-of-use carbon filter.
A carbon filter typically will produce filtered water at a faster rate than the other two systems.
