What is a Water Bottle Filter?
Many people have become aware of how important drinking pure, clean water is to health. As a result, bottled water has become very popular. There are two main disadvantages to drinking bottled water however. First, it can be quite expensive. Second, there is a huge environmental burden being created by all the plastic bottles needed for bottled water. Even with recycling programs in place, a massive amount of energy is used to recycle plastic. Often, all those little plastic bottles simply end up in landfill. The water bottle filter, or personal water filter, is an excellent alternative to bottled water.

Types of Water Bottle Filters
Most water bottle filters consist of a sports water bottle sized container that has a filter installed in the lid or drinking straw. Usually it is an active carbon or charcoal filter, or a ceramic filter. A portable water bottle filter is not able to use reverse osmosis to filter water, as the system requires a lot of space and wastes quite a bit of water.
Depending on the model, a water bottle filter is able to clean water of sediments and contaminants such as lead and mercury, while allowing healthy minerals to pass through. The water bottle filter is also able to filter out bacteria and viruses, as well as the chlorine that is added to treated water.
Cost of Water Bottle Filters
The amount of water that a water bottle filter can clean will vary with each manufacturer. Most will be able to filter about 100 litres of water before needing to be replaced, depending on the cleanliness of the water supply to begin with. The cost of the replacement filter may be nearly as much as the original water bottle purchase, so it is best to get a water bottle filter that will last. Ceramic filters can also be cleaned, and therefore last for quite a bit longer than sealed cartridge types. Most water bottle filters are in the $20 to $40 range, so the initial outlay is quite low. Compare this cost, plus the amount of water that a filter can clean, with the cost of the same amount of water in bottled form, and there will be a clear advantage to buying a water bottle filter.
Advantages of the Water Bottle Filter
Carrying a portable water bottle filter makes it possible to have clean drinking water available at anytime. Not only can they be used to filter out common contaminants and chemicals from a city water supply, they are also able to filter water from other sources, such as lakes and rivers. This makes them ideal for carrying in your car, RV, boat, or any other recreational vehicle.
A portable water bottle filter is also an excellent travel companion, for filtering water in hotels and the like. It is probably best to use bottled water in potentially dangerous places, however. There is still the possibility that some pathogens may get past the filter, so relying on the filter when another source of clean water is available may be taking an unnecessary risk.
A Personal Water Filter
Carrying a portable water filtering system in the form of a personal water filter, or a water bottle filter is an excellent alternative to buying bottled water. Not only is there the price advantage, but the water bottle filter does not contribute to landfill. The water bottle filter can be used to filter city water of dangerous chemicals, and also to filter lake or river water if you are in the outdoors. The water bottle filter is also very useful for travellers, acting as a guard against potentially dangerous pathogens that can lurk in hotel water supplies.
For those concerned enough about their health to drink bottled water in the first place, the water bottle filter is a sound investment whose benefits will far outweigh the cost.
