Under Sink Water Filters for Healthy, Great-Tasting Water

Under sink water filtration systems are a popular way to get healthier, better-tasting water because they remove more contaminants than most pitcher-based options and even bottled water. These systems are installed below your sink, enabling you to instantly enjoy clean water straight from the tap without taking up valuable counter or fridge space. By connecting to your water line, under sink filters provide a constant supply of filtered water — so you don't need to worry about refilling a tank or waiting for water to trickle through a filter block like with a traditional pitcher filter system.

Clean, healthy water is essential. After all, you use water for so much — from washing produce to watering plants to filling your family's glasses and your pets' bowls. The majority of municipalities use chemicals such as chlorine and chloramines to treat drinking water for bacteria, but the process can miss other contaminants that may be detrimental to your health. This is why we recommend installing a water filtration system under your sink, on your countertop, or for your whole house.

Compared to most pitchers, Nin Water Services' under sink water filters reduce 15x more contaminants. In fact, our filtration technology removes up to 99% of harmful contaminants including chlorine, chloramines, lead, microplastics, fluoride, PFAS, pesticides, herbicides, mercury, asbestos, and

others from your tap water.

Choose the Best Under Sink Water Filtration System for Your Home

We offer several under sink water filters to fit the unique needs of your home and family, and many include a dedicated faucet that dispenses filtered water. To help determine which under sink water filter is best for your home, start by reading your water quality report and consider what level of filtration you'll need to reduce contaminants present in your water.

All of our under sink water filters are tested and certified to reduce chlorine, chloramines, herbicides, pesticides, PFAS, pharmaceuticals and more in your tap water.

If you prefer a countertop water filter, we have options that also use tested and certified filtration technology proven to remove up to 99% of lead, asbestos, chlorine, chloramines, and more for a total of 78 harmful contaminants.

Under Sink Water Filtration System FAQs

What does an under sink water filter do?

Under sink water filters are a type of water filtration system installed below a sink and improve water quality by removing contaminants like lead, mercury, chlorine, and others. By removing contaminants, homeowners can improve the taste, smell, appearance, and overall safety of tap water to make it healthier and more enjoyable to drink.

Are under sink water filters worth it?

Under sink water filters offer a great combination of performance and affordability. They're a great choice for people who want to improve their water quality well beyond what's offered by a pitcher filter, but without the high cost of a whole house system. Overall, their straightforward installation, high performance, and ease-of-use make under sink filters a great choice.

How long does an under sink water filter cartridge last?

The lifespan of an under sink water filter cartridge depends on the type and usage. Typically, under sink filters will need to be replaced every 6-12 months. However, some filters have a longer lifespan than others. Usage can also affect how long a filter lasts, and heavy usage may cause a filter to exceed its capacity before the recommended replacement time.
