Unlike bulky pitchers, these filter systems efficiently use space beneath the sink. They also reduce the number of empty water bottles sent to landfills and oceans yearly.
Choose a system to target specific contaminants that your local tap water may carry. Check the product description for cartridge replacement schedules and other maintenance needs.
Better Tasting Beverages
An under-sink water filter is an investment in your home but one that could save you money in the long run. It removes contaminants from your water and can be installed in a location that’s easy to access. You can choose from several models designed to fit in your kitchen. Many also offer extra functionality that makes your time in the kitchen more enjoyable.
Most under-sink filters use either carbon or reverse osmosis filtration to eliminate unwanted particles and contaminants. Carbon models work by binding to the substances, while reverse osmosis systems force the water against a semipermeable membrane under high pressure. Both methods are more comprehensive than pitcher or refrigerator-mounted filters and help address various issues, including taste, odors, chlorine and other chemicals.
Many under-sink filters include a dedicated faucet to deliver the filtered water. They’re designed to intercept and redirect the cold-water line through the filter to prevent mixing with unfiltered water. This allows you to access filtered water at any point in your household and reduces the number of plastic bottles you need to buy.
You can find simple under-sink filter systems for less than $100 that’ll give you a few months of clean drinking water before the cartridges need to be replaced. According to financial experts, more robust options are available that will keep your water pristine for up to three years and cost between $150 and $250.
Some under-sink filter systems, like this one from Kraus, have a digital display monitor that shows how much contaminant has been removed and how much of the filter’s life remains. This feature is useful for monitoring the effectiveness of your filter over time and allowing you to plan for replacement.
A downside of under-sink filters is they typically have lower water pressure than regular kitchen taps. This means it will take longer to fill a glass and it may not be as cold as you’re used to. Some models have a built-in chiller that can make your drinking water more refreshing, but it comes at an additional cost.
Fewer Plastic Bottles
If you want to reduce the number of plastic bottles in your kitchen, an under-sink water filtration system is a great way to go. They offer several benefits that make them well worth the investment.
They’re easy to access, convenient and more comprehensive than pitchers, fridges,s or faucet-mounted filters. They eliminate sediment, chlorine, lead and other contaminants from drinking water before it reaches your glass. They also help improve tap water’s taste and quality, making it easier and more enjoyable to drink.
Under-sink filters can be more costly than pitchers and jugs, but they typically pay for themselves over time, thanks to the money saved on bottled water purchases. An under-sink filter could save you hundreds of dollars a year, depending on your water usage.
The best under-sink filters have multiple stages of filtration to ensure that your drinking water is as clean and healthy as possible. Look for systems that have been certified to filter a wide range of contaminants, including fluoride, arsenic and asbestos. Many brands also include an alkaline filter to add back in minerals that are often stripped in the filtration process.
One downside to an under-sink water filtration system is that it can take up room underneath your sink, and you may need to rearrange or redecorate your cabinets to fit the new equipment. This is especially true if you choose a multi-stage system like the iSpring RCC7AK 6-Stage Reverse Osmosis System, which includes a sediment pre-filter, reverse osmosis membrane and two final filters that address odor and taste and remove contaminants such as chlorine, pesticides, and lead.
Regardless of what under-sink water filter you choose, you should always follow the manufacturer’s instructions for installation and maintenance. For example, shut off the water supply to your system before installing or replacing the filter cartridge, and flush the system following your manufacturer’s guidelines. This helps to remove loose carbon fines and debris that might otherwise build up in the filter, extending its life. It’s also a good idea to invest in a high-quality water filter that independent experts have thoroughly tested to meet the highest quality and performance standards.
More Efficient Space
The cabinet underneath the sink is where many homeowners keep cleaning chemicals, making it an ideal spot for a water filter system. Unlike standalone filters that occupy a corner of the kitchen bench, under-sink systems divert cold water from the main pipes to a special tap for filtered drinking water. Because they don’t require a storage tank or drain, under-sink filters take up less space than their countertop counterparts.
Some under-sink filters are designed to be compact and work with existing faucets, while others use a separate dedicated faucet to dispense filtered water. The former option is typically the most cost-effective, while the latter often comes with a sleek design that can help add a touch of modern style to the kitchen.
Undersink water filters are also designed to be easy to maintain. Most models only need cartridge changes, usually performed in under a minute. Also, under-sink filters don’t require any other complex maintenance procedures.
When comparing different under-sink water filter systems, it’s important to consider their filtration capacity and the number of contaminants they can remove. Single-stage systems are the most affordable options and tend to focus on one specific contaminant, while multi-stage filters can tackle more of them.
For example, this under-sink water filter from Aquasana uses two separate filtration stages to reduce up to 61 contaminants, including chlorine (which affects taste), lead and other heavy metals, plus PFOs and PFOAs. This makes it an excellent choice for households with well water tested for these substances.
When choosing an under-sink water filter, it’s essential to read the product description and check for third-party certification. This is the best way to ensure a filter can remove all the contaminants listed rather than just a few. Once you have found a suitable model, it’s time to enjoy your fresh, healthy, clean tasting drinking water.

Less Waste
An under sink water filter system in your kitchen is a great investment that will help you reduce wasteful plastic bottles that can cause harm to the environment. It can also help you save money by eliminating the cost of buying bottled water at the store and by cutting down on other costs associated with consuming contaminated drinking water like detergents, soaps and energy bills.
Undersink filters are very easy to maintain and don’t require much complex maintenance work to keep them performing properly. In most cases, you only have to replace the filter cartridges every 12 months, which isn’t too bad for a system that will help you reduce potentially harmful contaminants and improve your family’s overall health.
Depending on your preferences and budget, you can choose between a simple carbon under-sink water filtration system or more robust reverse osmosis options. Both options can help improve your family’s water quality, but there are some important differences between the two. A simple carbon filter intercepts your cold water supply underneath your sink and diverts the water to a special faucet for filtered consumption. The regular cold and hot water functions of your sink remain unaffected.
On the other hand, a reverse osmosis under-sink system works differently in forcing your water through a semi-permeable membrane at high pressure to remove unwanted contaminants. This process can reduce a larger range of contaminants and minerals, including lead, chlorine odors and unpleasant tastes, and PFOAs and PFAS.
A reverse osmosis under-sink water filtration system is a bit more expensive. Still, it may be worth the extra expense for those who are looking for an under sink filtered water system that is capable of reducing a greater range of contaminants. These systems are also more difficult to maintain since they will have an additional water storage tank and drain line that needs to be connected.
You must read the product manual for any under sink water filtration system before installing it yourself. You should only try to do this if you are confident in your plumbing abilities and are comfortable following instructions. Otherwise, you should consider hiring a plumber to ensure the job is done correctly and will last for years.
