Water filters eliminate unwanted impurities from tap water, making it safe for drinking. With the multitude of filtration systems available, it can be challenging to know which one is best for your family. To get started, order a water quality test to learn about the types of containments in your drinking water. Here are five common types of home water filters you might choose for your household.
Types of Home Water Filters: Activated Charcoal
Activated charcoal filters are one of the most popular home water filters. They contain carbon that attracts and removes chlorine, dirt, and volatile organic compounds. These water filters are easy to use and available in different styles. Purchase a pitcher filter, one that is attached to your kitchen sink, or opt for a whole-house filtration unit.
Ion Exchange Water Filters
If you notice chalky residue on your washed dishes, you may have a hard water problem. Ion exchange filters contain a substance that exchanges one type of ion for another as water passes through it. These filters replace magnesium or calcium ions, which contribute to water hardness, with sodium ions to soften the water.
Although an ion exchange filter helps soften hard water, it doesn’t remove bacteria, particles, or organic contaminants as effectively as other home water filters.
Reverse Osmosis Filters
A reverse osmosis filter is one of the most effective water filters. This filter uses a semipermeable membrane to block impurities while letting water molecules pass through it. The membrane has very tiny pores, making it possible to eliminate up to 99% of contaminants, including dangerous bacteria.
While these systems are becoming incredibly popular, reverse osmosis uses an excessive amount of water. They sometimes generate up to four gallons of waste water for every gallon of clean water produced. The process is also relatively slow, which can decrease water pressure. Inefficiency is why you won’t find a whole-house reverse osmosis system. The level of filtration they provide isn’t necessary for daily activities such as taking showers, flushing toilets, and doing the dishes.
UV Water Filters for the Home
As the name suggests, UV filters use ultraviolet light to eliminate viruses and bacteria. These rays attack pathogens and can destroy 99% of all disease-causing microorganisms. However, if you opt for a UV purifier, install a secondary water filter to ensure sediment and harmful contaminants are also removed.
Sediment filters remove sand, rust, and silt. Although you can use it alone, it’s always best to combine sediment filters with other types of filtration to get the best results. Sediment filters only remove contaminants larger than their micron specifications, meaning other pollutants will pass through and end up in your drinking water.
Have your water tested if you’re uncertain about the type of home water filter to purchase. Understanding what kinds of contaminants are in your drinking water will help you choose the best water filter for your household.
