Water Filter For Under the Sink

Take a look at Multipure’s Aquaversa: it’s powerful, it’s convenient, it’s easy to use, and it’s affordable. No wonder it’s one of the most popular countertop and under sink filtration systems we’ve had to offer. 

Every home deserves clean drinking water, safe for you and safe for your family. For most communities, tap water is disinfected before it goes out to homes and businesses, making it generally safe to use. Unfortunately, there are new contaminants and new dangers discovered in water supplies regularly, waiting to be discovered in your water.

Good thing for everyone that Multipure is here with the best countertop and under sink water filters on the market.

Benefits & Features

The Aquaversa’s features make it more useful and convenient than other countertop or under sink filtration systems on the market. These features include:
  • Better Tasting Water – Ever wonder why tap water sometimes tastes funny? That’s the chlorine, chloramine, or other contaminants in the water. Ever wonder why bottled water sometimes tastes funny? That’s the plastic, or the fact that it may just be bottled tap water. When you drink water that's been filtered by the Aquaversa, you’ll taste the difference – not just with every glass of water, but for the taste of coffee, tea, juice mixes, and whatever other beverages you make with it.
  • Healthier Water – As an NSF-certified water filtration system, the Aquaversa can help protect your family from harmful contaminants in tap water. Many filtered pitchers or under counter water filters don’t do more than improve the taste of the water. With the Aquaversa, your water is protected from a wide range of hazardous compounds and chemicals in your water.
  • Better Cooking – Have you ever seen someone crack open a half dozen bottles of water to cook with? Probably not, because that’s both tedious and expensive. But not a lot of people think about cleaner water for preparing foods or cooking. Cooking with water filtered by the Aquaversa countertop or under sink water filter system means that contaminants are treated before they can affect your food. Aquaversa filtered water is perfect for making pasta, soups, sauces, and any other foods that need water.
  • Versatility to Meet Your Needs – You can have your Aquaversa water filter ready to go almost immediately, installed to fit the needs of your kitchen and your space requirements. If there's no room on the counter, set it up as an under sink filtration system installation. If there’s no room under your sink, install it on the countertop next to the sink. The Aquaversa is designed for flexibility and convenience.
  • Treat Your Pets Right – Don’t buy expensive bottled water for your pets, and don’t risk feeding them potentially contaminated tap water. Fill their bowls right from the Aquaversa filtered water spout, confident that they are getting the same cleaner, healthier water that you are.
  • Save Money – End your relationship with bottled water for good with your Aquaversa installed on the counter or as an under sink filtration system. Ditch the high cost of disposable plastic bottled water, and reduce the burden that plastic bottles have on the environment.

Order your Aquaversa now, and enjoy the benefits of cleaner water for better health and better lives.

System Options

Base System

The base Aquaversa system can be used in-line with other existing hardware (e.g., existing faucet, ice maker, etc.), but includes no additional plumbing hardware. It can utilize compatible below-sink and countertop parts and accessories.

Below-Sink Kit

This installation kit includes a stand-alone chrome faucet and the necessary hardware to attach the system to a cabinet wall below the sink. The system connects to the cold water line with an included Adapta Valve, and the faucet requires a 0.5” hole available in the countertop or sink for installation.

A below-sink Aquaversa is intended for a more permanent installation, although it can be removed and converted for countertop use with the optional countertop kit. The below-sink Aquaversa is designed to mount on the side of the cabinet, but can rest on the floor of the cabinet with an optional acrylic base (MC840).

Countertop Kit

The standard countertop installation kit includes a dual-hose diverter valve and an acrylic base that allows the system to sit on top of the counter next to the sink. The system connects to the sink faucet with the dual-hose diverter valve, outputting filtered water from a spigot on the diverter valve itself. Filtered or unfiltered water can be selected by a push-button on the diverter valve.

Due to the many varieties, styles and sizes of kitchen and bathroom faucets, Multipure cannot guarantee that the countertop kit and adapters will be compatible with your faucet. Please contact Multipure’s Customer Care department for assistance.

Single Hose Diverter Kit

This installation kit includes a single-hose diverter kit and an acrylic base that allows the system to sit on top of the counter next to the sink. The system connects to the sink faucet with the single-hose diverter valve, outputting filtered water from a faucet attached to the top of the system housing. Filtered or unfiltered water can be selected by a push-button on the diverter valve.

Due to the many varieties, styles and sizes of kitchen and bathroom faucets, Multipure cannot guarantee that the countertop kit and adapters will be compatible with your faucet. Please contact Multipure’s Customer Care department for assistance.

Capacity Monitor

Includes a battery-operated capacity monitor that measures the amount of water processed through the drinking water system and reminds you when to change the filter; an included light indicator is located at the base of the faucet and lights up when the filter needs to be changed. NOTE: The Capacity Monitor is recommended for Below-Sink Kits.

NOTE: Both the monitor and light indicator are battery-powered (2 x AA batteries not included); batteries need to be changed each time the filter is changed.

    Easy installation

    The new design is easier to install with the quick connectors and the versa valve. Also the wall plate was nice.

    Working good

    Posted by Ralph Paul Finklea on Mar 13th 2023

    I have only had 2 weeks. Installation was pretty easy under sink. The filtered water taste better than my tap water. If the filter continues to perform up to advertisements it is a 5 star filter.

    Installed today and I'm very happy

    Posted by Joanna Jimenez on Jan 27th 2023

    in New York City the old filter from a year ago was dark brown. It caught a massive amount of pollutants in a sink top model 400. Now I have space on my sink top and a higher capacity filter.

    Excellent product

    Posted by Steve Dean on Dec 3rd 2022

    Yields the best tasting clean water. This is my 4th below sink unit as we have moved several times and I always leave the unit in the house as it is a positive selling feature. My first unit was a model 500 back in 1989. The housing units are bullet proof, have never leaked nor failed in any way. Filters are easy to change and I have peace of mind knowing we are consuming good, pure water!

    Aquaversa Below Sink model

    Posted by Joanne Kraft on Nov 9th 2022

    I have had my Aquaversa filter for 34 years. I simply change the NSF Certified cartridge 1/year. At $0.12/gallon, I can afford to rinse my vegetables/fruit, water my house plants and to give filtered water to my pets! The Multipure product warranty continues to protect my Aquaversa filter. It is the best appliance purchase that I have ever made! My Mulitpure unit is the only appliance in my home that I have not replaced! I have saved so much money by using my

    This is a great filter and one we've had for over 25+ years. Way better than lugging home cases of water from the store and much better quality drinking water.

    This solid carbon block filter changed everything…

    Posted by Denise Downey on Nov 8th 2022

    When we first tried our Multipure Aquaversa and tasted really clean water, it was very easy to start drinking fresh water every day… And when we started brewing our coffee with Multipure water, that sold us completely! Aside from great taste, knowing that Multipure removes 99.99% of all harmful contaminants, gives us total piece of mind - in the house, on the road, camping, everywhere! Thank you, Multipure, for this life-changing technology - we love it!!

    I’m a WATER SNOB!

    Posted by Diane Dvirnak on Nov 8th 2022

    I have been using a Multipure Aqua versa since 1992. I have owned several in each home I have owned. My kitchen unit is always hooked into the ice maker in my kitchen and also at the kitchen sink. All my cooking, washing of fruits and veggies is done with MULTIPURE! I’m so spoiled! I carry my water wherever I go. Yes, I’m a water snob!
