Common Types of Water Filters

Due to a large selection, shopping for a water filter is not always as straightforward as it sounds. Fortunately, as you learn more about the many types of water filters, you’ll find it easier to decide on the one that’s best for your home.

Before we discuss the most common types, let’s examine the many methods of water filtration:

  • Activated alumina water filter
  • Filter with activated carbon
  • Ceramic filter
  • Reverse osmosis filter
  • Ultraviolet water purifier
  • Water distillation

Now, with that in mind, here are the most frequently used water filters in American homes:

1. Water Filter Pitcher

Not only is a water filter pitcher affordable, but its portability makes it a top choice.
These pitchers are designed to have two parts:

  • The upper part, which houses a filter with activated carbon
  • The lower container, which is where the water is housed before pouring


  • Portable
  • Affordable
  • Low cost
  • Effective in removing minerals and chemicals


  • Slow
  • Confined capacity

2. Faucet Water Filter

On the surface, this is nothing more than a small device that attaches directly to your faucet. With this arrangement, it filters the water as it comes out of the faucet.


  • Affordable
  • Compact
  • Easy to install
  • Convenient


  • Doesn’t work with all types of faucets
  • Slows down the flow of water

3. Showerhead Filter

This is exactly what it sounds like: a filter that fits onto your showerhead, much the same way as a faucet filter

It’s perfect for people who are concerned about the purity of their bath water.


  • Inexpensive
  • Easy to install
  • Compact
  • Removes contaminants to improve skin and hair health

4. Countertop Water Filter

These devices, which also connect to the faucet, are perfect for people who want to purify their water without the need to constantly fill a jug.

With the ability to purify water from the moment you turn on your tap, it’s among the most convenient options.


  • Greater filtration than a basic faucet filter
  • Affordable (although more expensive than a faucet filter)
  • Fast purification

Under Sink Water Filter

As one of the most effective water filtration systems, these are popular in many homes. Located under your sink, it removes pollutants and bacteria from your water at a fast rate.


  • Ability to treat more water in a shorter period of time
  • Hidden under the sink for a cleaner look
  • Can filter more contaminants than other types


  • Difficult to install
  • Expensive

Whole House Water Filter

If you want to filter every bit of water that enters your home, this is the way to go. It’s typically, but not always, installed in homes where tap water is unavailable.

Most of these filters are installed at the water tank, so they can connect to the main line that runs into the home.


  • Filters water as it enters the home, so you don’t need separate filters
  • Most effective in removing contaminants
  • Cost savings over the long run


  • Requires professional installation
  • Expensive

With so many types of water filters to consider, it’s essential to keep an open mind. Now that you understand the pros and cons of all your options, you’re in position to make an informed decision.
