Undersink System and Filters

Nothing can be more refreshing than drinking a glass of cool, crisp water. Water is necessary for everyday life; not only does it sustain us, but it keeps us rejuvenated and energetic as well. Our bodies are made of 55-70% of water, so it is important to drink plenty of water to keep our bodies replenished and healthy. Unfortunately, water is not everyone’s favorite drink, and sometimes that is due to the unpleasant taste of tap water.

The water that comes into our houses is treated with chlorine, which leaves a less-than-tasty effect on our drinking water, and it also contains impurities that, though not necessarily unhealthy, can have a negative effect, especially on the little ones. There is a solution to healthier, better tasting drinking water—an undersink filter system.

An undersink filter system fits under a sink, whether it is in your kitchen or in your bathroom or wherever. Undersink systems work similarly to countertop filter systems, except they attach to the faucet under the sink, a feature that saves counter space and annoyance. With an undersink filter, you do not have the annoyance of trying to get a glass of water around a sink full of dishes, and you also have more room for counter space and for washing dishes or brushing your teeth, etc.

Though undersink water filter systems usually require a bit of change to your plumbing, they are usually worth it in the long run. They generally last longer and are even sometimes more efficient than other drinking water systems. Also, many systems come with a dispenser that allows you to choose between filtered and unfiltered water. The best part is that you get clean, better tasting water!

Replacement Filters

The filter is the most important feature of any filtration system. The type of filter determines what types of particulates are removed, how many, and so forth. It is also very important to remember to keep your filters regularly replaced, which keeps the system more efficient and fresh, clean water always available.

Most filter cartridges for the undersink systems use carbon media. When a carbon source like coconut shell is activated with oxygen, millions of extremely tiny, highly absorbent pores are created in the media. This makes carbon media highly absorbent for trapping contaminants like odors, chemicals, and particulates in water.

We offer several undersink water systems and filters:


If you want better tasting water that is free of chlorine, bad tastes and odors, then Culligan is great for the job. Especially good for city or well water users, Culligan filters effectively reduce chlorine, bad tastes/odors, and particulates in water, delivering cleaner water with a great fresh taste!


We offer several replacement filter cartridges for GE undersink water filter systems. Some of them are single stage filters, some dual stage filters, but each lasts about 6 months before they need to be replaced. Different contaminants are removed depending on the filter. All of the filters make water taste better and fresher by removing chlorine taste/odor, sediment, and cysts. Others, depending on the filter, remove contaminants like VOCs, mercury, lead, asbestos, rust, turbidity, etc.

Crystal Quest

Crystal Quest is a brand that uses several stages of filtration to remove a wide variety of contaminants from the water. All of the filters use at least 6 stages of filtration, in which they remove contaminants such as suspended particles like silt, cysts (cryptosporidium and giardia), sediment, rust and sand; heavy metals like mercury, lead, copper, and nickel; and chemicals like VOCs, benzene, and pesticides. The double and triple cartridge systems have additional cartridges for capturing more harmful contaminants.


For water that is as clean and clear as water fresh from a mountain brook, ClearBrook water filters provides great tasting, high quality water. This long-lasting filter, which can last up to 5 years (depending on use and water quality), removes contaminants like chlorine, bad tastes/odors, sediment, VOCs, and organic chemicals. As an added bonus, the filter also inhibits bacterial growth, providing pure water with a great taste!

Aqua Pure
