Choosing a home water filter can be daunting given the numerous options in the market. However, the task gets easier once you establish the kind of contaminants you want to get rid of. The decision further depends on the volume of water you want to filter and the budget. This guide explains all you need to know about home water filters.
The water in your tap could contain all sorts of contaminants, including chlorine, fluoride, nitrate, viruses, bacteria, and heavy metals among others. While some of the elements are necessary for our well being, they turn harmful when they exceed allowable levels. You should look at the most recent annual water report by your city to know which contaminants are present.
Types of Home Water Filters
It requires different approaches to get rid of the contaminants found in water. While some methodologies are simple, others call for the use of sophisticated filters. There are five types of filters commonly used for water filtration today. These include activated carbon, reverse osmosis, ultraviolet, infrared, and ionization filters.
- Activated carbon filters — these work by attracting large particles so that the final product is clean. They also eliminate bad odor and excessive chlorine.
- Reverse Osmosis — these filters have the ability to remove all contaminants thus producing very safe water for drinking. Unfortunately, they waste a lot of water and are not the most eco-friendly.
- Ultraviolet filters — the contaminated water passes through ultraviolet rays that in turn kill all bacteria present. These are some of the most eco-friendly filters since no chemicals are added.
- Infrared water Filters — Infrared filters use heat and light to charge the contaminated water negatively. They are mostly used to soften hard water.
- Water Ionization Filters — Water passes through electrically charged plates which in turn separate into acidic and alkaline streams. These are mostly used in locations with hard water.
Other Considerations When buying a Home Water Filter
Home water filters are further categorized as a point of entry or point of use filters. In the case of POE filters, all water used in your household passes through the filter. These fillers are more expensive but have higher levels of water safety. On the other hand, POU filters are only fixed at the water outlet. These could be used to filter water for drinking or cooking.
Finally, home water filters are available at different prices. Choose a filter that falls within your budget range as long as it fulfills the other requirements. Also, check the possible costs of repairing the unit to avoid unmanageable maintenance costs.
The choice for a home water filter largely depends on the contaminants you want to eliminate. Choose a filter that falls within your budget range while serving all your filtration needs.
