The Best Water Filters Out The Market
Cheap water filters do very little to purify drinking water. About the only thing they are good for is costing consumers a lot of extra money when purchasing replacement filters. Yet a high quality filter will give the owner years of service, thus saving money. Generally, if it costs less than a couple hundred dollars, then put it back on the shelf. Let’s take a look at a few simple steps to take when buying the best water filters to ensure that they will be cost efficient, highly effective and last for years to come.
The first step is to decide what you want to accomplish with a water filtration; do you want to reduce chlorine, stop bacterial growth and cysts, or would you like to deal with a wide range of organic and chemical contaminants all at the same time? The best water filters can do all of these things at one time. You should also consider whether or not you want to remove the healthy minerals from your water, such as calcium and magnesium.
If you take a look at loose carbon filters, you will discover that they are actually bacteria factories. They allow oxygen to exist within the filter, which encourages and enhances the growth of bacteria. Although this type of filter is very cheap to purchase, it is expensive in the long run, since the filters must be replaced frequently.
Distillation is effective when filtering bacteria, solids, sediments and organic or chemical contaminants that will not evaporate. There are some chemical contaminants, such as MTBE, that will evaporate, so distillation is not effective in filtering that.
Ultraviolet (UV) light is sometimes used in conjunction with other filters to kill bacteria, and has been found to be a very effective tool. The light affects an organism’s DNA, so it cannot replicate. If it cannot replicate, it is harmless.
Reverse osmosis (RO) is a filter which reduces fluoride, radium and numerous other contaminants to a very high degree, although it does have its limitations. There are a large number of contaminants found in water that will easily pass through an RO filter. Reverse osmosis is also used in conjunction with other filters to be very effective, though the process does remove the healthy minerals as well. RO by itself is capable of reducing contaminants such as radium, arsenic, barium lead, nitrates and nitrites, as well as giardia and selenium that are found in tap water.
The best water filters tend to have a long life capacity, and that is what saves money. Be on the lookout for a water filter that has a capacity rating of six months or longer, and understand that this number is an estimate. The actual lifespan of the filter depends on the quality of your water. If your water has a lot of contaminants to filter, then your unit will clog sooner.
