The Best Water Filters Today
For even the savviest of shoppers, buying a water filter in today’s marketplace can be confusing. Hopefully, this article can assist you in making the right choice when purchasing a new filtration system for your home or business. When it comes to water purification, there are quite a few different technologies to choose from, such as loose carbon, distillation, ultraviolet light, reverse osmosis and carbon blocks. Let’s take a look at what are the best water filters available today and how each of them works.
Like everything else, when it comes to the best water filters, quality tends to cost money. Typically, a good quality water purification system will cost a couple hundred dollars to buy, but will end up saving you money in the long run because they give you delicious and clean water that is fit for human consumption for a fraction of the cost of replacement filters.
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.
