Good quality drinking water is important when it comes to your family’s health. Using a water filter is a great way to stop spending money on bottled water while still enjoying clean, pure water that tastes great and is free from harmful contaminants. Read on to learn about five types of water filters for the home.
1. Reverse Osmosis Water Filters
A reverse osmosis filter uses water pressure to force water through a finely perforated semipermeable membrane. The fineness of the filter removes impurities like sulfates, pesticides, nitrates, chlorine, fluoride, and even lead.
Reverse osmosis home water filters are highly effective, but their filter membranes are delicate and can be easily damaged. The membrane’s perforations can also clog because the mesh is so fine. The filters need to be replaced over time and the entire filtration system should be cleaned yearly.
2. Activated Carbon Water Filters for the Home
Activated carbon water filters are appealing due to their natural approach to water filtration and the fact that they are very affordable. The porous surfaces of the activated charcoal pieces remove impurities from the water without added chemicals.
However, activated carbon filters only remove particles from the water that are attracted to charcoal. This includes heavy metals, sodium, nitrates, microbes, and fluoride. Activated charcoal also takes time to do its job, meaning that the filtering process is slower compared to other water filters for the home.
3. Water Ionizers
Water ionizers remove the vast majority of lead compounds and other contaminants from your drinking water. The ionization process takes place after contaminants such as bacteria, heavy metals, and unwanted minerals are filtered out. Ionizers work by using electrolysis to separate acidic and alkaline components from the water they process, meaning that you can enjoy alkaline water on demand.
The cons of these types of home water filters are mainly cost-related. Not only are these filters expensive upfront, but their repairs are pricey. Many of the claims that alkaline water offers health and anti-aging benefits remain scientifically unproven.
4. UV Water Filters for the Home
Ultraviolet (UV) home water filters are popular for decontaminating water in areas where bacteria and other microorganisms are prevalent in the water supply. These filters work by using ultraviolet light to destroy the DNA of water-borne pathogens, making this type of water filter effective at eliminating harmful bacteria without the use of toxic chemicals.
Unfortunately, UV filters only serve to kill off microorganisms and do little to filter out heavy metals, chlorine, other chemicals, or particulate matter.
5. Water Distillers
Water distillers effectively remove particulate matter and minerals from the water that may cause an unpleasant smell and taste. They also do a passable job of killing bacteria during the distillation process, although some microorganisms are left behind, along with volatile organic chemicals.
A primary con of water distillers is that they remove minerals indiscriminately, stripping the good along with the bad. They’re also relatively inefficient in their use of water and can contribute to indoor humidity while taking up a great deal of counter space.
Shopping for a Water Filter
The best way to make a decision when shopping for water filters for the home is to have your water tested so you know the contaminants in your local water supply. Filtration systems take different approaches to water purification, so knowing the pollutants and contaminants in your water supply will help you make the best choice for your home.
