Undersink Water Filters vs. Pitcher Filters Comparison

August 20, 2023 3 min read

When it comes to improving the quality of your drinking water, there are several options available, including undersink water filters and pitcher filters.


Both of these systems offer unique advantages and drawbacks, and choosing the right one for your needs can be a challenge. In this article, we will compare undersink water filters and pitcher filters, discussing their respective features, benefits, and limitations to help you make an informed decision. Let's explore the world of water filtration!

Undersink Water Filters: An Overview


Undersink water filters are installed directly under your kitchen sink and connected to your home's plumbing system. These filters effectively remove a wide range of contaminants, such as chlorine, heavy metals, and harmful microorganisms, to provide clean, safe, and great-tasting water straight from the tap. The Awesome Water Filters H2O Undersink Water Filtration System Kit is a top-notch example of an undersink water filter system.

Pitcher Filters: An Overview

Pitcher filters are portable water filtration devices that consist of a water container equipped with a replaceable filter cartridge. The water is poured into the pitcher and passes through the filter, which removes contaminants before the water reaches the bottom of the container. These systems are easy to use, affordable, and do not require any installation.

Key Comparisons

  1. Filtration Efficiency

Undersink water filters generally offer superior filtration efficiency compared to pitcher filters. They typically use multi-stage filtration processes and can remove a broader range of contaminants, including heavy metals, chemicals, and microorganisms. In contrast, pitcher filters are usually less effective at removing certain contaminants, particularly heavy metals and some chemicals.

  1. Convenience and Accessibility

Undersink water filters provide clean water directly from your tap, making them a more convenient option for daily use. With a simple turn of the faucet, you can access filtered water for drinking, cooking, and other household tasks. Pitcher filters, on the other hand, require manual refilling and can be cumbersome if you need large volumes of filtered water.

  1. Installation and Maintenance

Undersink water filters require installation, which may be a drawback for some homeowners, particularly those who rent their homes or lack DIY skills. However, once installed, these systems offer low maintenance, with filter replacement typically needed every 6-12 months. Products like the PP Filter and Carbon Water Filter Cartridge and the HiFlow 0.5 Micron Inline Water Filter Replacement Cartridge make filter changes straightforward. Pitcher filters, on the other hand, do not require installation but need more frequent filter replacements, often every 2-3 months.

  1. Cost

Undersink water filters tend to be more expensive upfront but can be more cost-effective in the long run due to their longer-lasting filter cartridges and superior filtration performance. Pitcher filters are usually more affordable initially, but the ongoing cost of replacement filters can add up over time.

  1. Space Considerations

Undersink water filters are installed beneath your kitchen sink, conserving counter space and keeping your kitchen clutter-free. Pitcher filters, on the other hand, take up counter or refrigerator space, which can be a concern for those with limited storage options.

  1. Environmental Impact

Undersink water filters are generally more eco-friendly, as they produce less waste in the form of disposable filter cartridges. In contrast, pitcher filters require more frequent filter replacements, which can contribute to increased plastic waste. Additionally, using an undersink water filter reduces your reliance on bottled water, which further lowers your environmental impact.

  1. Customizability

Undersink water filters offer more customization options, as you can choose from various types and configurations to address specific water quality concerns. This versatility allows you to find a system that best meets your needs. Pitcher filters typically have fewer options, with most models targeting a limited range of contaminants.



Ultimately, the choice between undersink water filters and pitcher filters depends on your specific needs, preferences, and budget. Undersink water filters offer superior filtration performance, convenience, and cost-effectiveness over time, making them an excellent choice for homeowners seeking a long-term water filtration solution. However, pitcher filters may be more suitable for those who require a portable, affordable option with no installation requirements.

If you decide that an undersink water filter is the best fit for your home, consider investing in a high-quality system like the Awesome Water Filters H2O Undersink Water Filtration System Kit to enjoy clean, safe, and great-tasting water straight from the tap. By carefully considering your needs and weighing the pros and cons of each option, you can make an informed decision and choose the best water filtration solution for your home.
