Types of Countertop Water Filters

The three types of water filters for the countertop are:

Faucet Based Filters

Carbon-based faucet water filters are quite effective in reducing pollutants, chlorine, and total dissolved solids. They also remove lead, mercury, sand, and sediments as well as disease-causing cysts. Most faucet-based filters are easy to install and you do not need any major plumbing changes.

First, the filter should be easy to use and install. You should not need any plumbing changes. Second, if it is electrical and needs plugging in, find out its voltage requirements. Finally, make sure that the filter gives you pure water at desired temperature in minutes and not hours.

Comes With Adequate Storage Capacity

If possible, select a unit having a reservoir that meets your family’s daily drinking water needs.

Has a Long-Lasting Filter

The last thing you want is a filter that needs frequent replacement of its cartridge which can be quite expensive. A high-quality water filter can last several 1000 gallons or up to 2 years.

Ease of Filter Replacement

This is also an important feature to consider while selecting best countertop water filters. Make sure that the filter is easy to replace, not too expensive, and is as easy as turning the unit and screwing in the filter.

What Contaminants Can Water Filters Remove

The EPA or the Environmental Protection Agency classifies contaminants into the following types:

Pathogens

Pathogens include parasites, bacteria, fungi, and viruses. They also include cysts of protozoa such as Giardia and Entamoeba as well as cryptosporidium. The recommended absolute filter pore size for removing these pathogens is 1 micron. Most countertop water filters listed above are known to eliminate these pathogens.

For removal of bacteria like E. coli, salmonella, and shigella, the recommended pore size is 0.2 to 0.4 microns. Viruses like rhinovirus are very small and many filters are unable to remove them. Filters with Reverse osmosis and UV technology can kill some of these viruses.

Organic and Inorganic Chemicals

Petroleum, plastic, coal, herbicides, rust, corrosion from plumbing, and the erosion of natural deposits can, overtime, cause certain cancers. These chemicals also damage the delicate organs. Distillation and reverse osmosis can remove most chemicals.

Disinfectants

Water treatment plants add chlorine to the water to disinfect it. However, chlorine, chloramine, and other by-products and additives can, over time, cause cancer as well as diseases of the liver, kidneys, and neurological systems.

Radionuclides

The good news is that US water does not contain too much radioactive contaminants. However, the ones that are present are the result of erosion of natural deposits of minerals. Although filters with ion exchange, Reverse osmosis, and lime softening can remove these contaminants to an extent.

Difference Between Water Filter and Water Purifier

Often, the terms water filter and purifier are used interchangeably. In general, a filter is any device that removes contaminants from water. This can be as crude as a coffee filter although, these days, filters mean devices that have some sort of membrane. Most basic water filters remove protozoa, bacteria, and some other common contaminants.

However, contrary to popular belief, they do not remove minerals, heavy metals, and salts. Lastly, according to the EPA, a water purifier is a special type of water filter that reduces all contaminants to 99.999% levels. That is why; a certified purifier or filter is the best because it is sure to offer protection from most water contaminants.
