Under Sink Water Filter

A fter the Flint incident, people all over the U.S. have realized that trusting the work done by the municipality might not always be the best solution. Water is something that we cannot live without, we need it for hydration, cooking, cleaning, and washing. But it is not a matter of quantity alone as the quality of the water matters just as much, if not more, reliant on the use you intend for it and the specific pollutants that alter it.

To fix these issues, you require an effective filtration means set in place, and in this article, we will explore the capabilities of under-sink water filters. More convenient installation-wise as they are out of sight and don’t need much space either, they provide the benefit of pure potable water at the faucet. Their proficiency is similar to that of whole-house systems, the sole dissimilarity standing in the fact that their action affects a single tap, the one afferent to the sink you set it up for, rather than for the entire house.

As more research has gone into development, their efficiency in pollutant removal has grown as well, and hereafter, we will present you with what we view as the most effective models at the moment.

If you want to have clean, uncontaminated water pouring from all the taps in your home, check out the best whole house water filters for well and install one to never have another water purity issue.

Under Sink vs Countertop Water Filters

Under Sink Water Filters – Pros & Cons

Pros:
  • Out of sight: What is undoubtedly the most obvious advantage of the under sink system is that it stays out of sight. This means that it won’t interfere with the design of your kitchen, allowing you to preserve the room as you like when it comes to its appearance.
  • Free up counter space: Counter space is precious, especially in small-sized kitchens. With it, you can rest assured knowing that no space will be lost as it doesn’t reside on the counters you need for placing appliances and cooking tasks.
  • Great filtration rate: When pinned side by side, under-sink models generally boast better filtration rates as opposed to their countertop counterparts. This implies a higher efficiency in cleaning your drinking water, and thus are a better choice for your health.
  • Keeping healthy minerals: What quality systems have in common is the fact that they help preserve healthful minerals in the water, minerals which include magnesium and calcium. Thus, you won’t only hydrate with clean water, but the liquid you consume will provide you with the needed minerals for an improved and boosted overall health.
Cons:
  • Harder to install: In contrast to countertop models, they are more difficult to install as they require some level of handy work. However, you need not get discouraged as the installation process is generally simplistic and explained in detail in the installation manual that accompanies each product.
  • Larger in size: Don’t get us wrong, when we refer to the systems being large in size, we mean when compared to countertop models. Evidently, their footprint is larger, but it isn’t all that big as to become an issue, and seeing how they install underneath the sink where it is unlikely that you keep anything else, size won’t ever be an actual issue.

Countertop Water Filters – Pros & Cons

Pros:
  • Small footprint: As they are intended for placement on the counter, these products tend to boast a small size that makes them quite a discrete addition to the kitchen.
  • Easy to install: As these systems generally only require a connection to the faucet, they are simpler to install, the procedure usually taking only a few minutes.
Cons:
  • Slow filtration: These systems take a longer amount of time to filter the same amount of water as under sink models do, which is an obvious downside as it compromises their efficiency.
  • Occupy useful space: No matter how compact the system is, one thing is for sure – it takes up counter space. For those who have small kitchens where the counters are already cluttered with other useful appliances, this aspect is a negative one for sure.
  • Design wreckers: If you care for the design of the kitchen, you won’t be delighted by ruining it with the addition of a bulky and mismatched appliance like the countertop water filter.



Common Tap Water Contaminants


While the list of potential pollutants that could be afflicting the tap water quality is in the order of thousands, there is a shorter list of pollutants you are most likely dealing with, irrespective of the area you live in. Woefully, the effects these pollutants have on your health can be devastating depending on the period of ingestion, contamination levels, and your health state when exposed to them. Water filtration is the sole solution to keep the health effects of these contaminants at bay. To increase awareness regarding potable water purification, we will talk a bit about some of these common pollutants.

Chlorine:
Intentionally added by multiple community water systems into the water supply to regulate the growth and spreading of microbes, chlorine not only impacts human health through direct consumption or bathing, but it can cause air quality decrease indoors when it evaporates from the bath/shower, and causes an unpleasant taste and smell of the water.

Chlorine – Health Effects
Nose irritations, Skin irritations, Eye irritations, Dry hair, Dry skin

Chloramines:
Generally added as an extra measure of disinfecting water in the municipal system, chloramines form when free chlorine water is mixed with ammonia.

Chloramines – Health Effects
Aggravation or causation of respiratory problems, Asthma, Mucous membrane damage, Skin irritations, Eczema, Red eyes, Digestive disorders, Gastric cancer, Ammonia toxicity

Lead:
A toxic metal that is dangerous even in low levels and that you must make sure to never consume.

Lead – Health Effects
Leaning disabilities, Growth retardation, Weakened hearing, Impaired formation of blood cells, Peripheral nervous system damage, and Short stature in children, as well as Increased blood pressure, Raised incidence of hypertension, Reproductive problems, and Decreased kidney function in adults

Pharmaceuticals:
Synthetic chemicals that are found in medication, pharmaceuticals are common in water streams because of improper disposal and uncontrolled manufacturing facilities.

Pharmaceuticals – Health Effects
Developmental issues in children

Cysts:
Microbial parasites that are resistant to the disinfection processes used by municipalities on the water supply, they enter the water through sewage and leaks.

Cysts – Health Effects
Intestinal illnesses, Nausea, Breathing difficulties

Volatile organic compounds:
VOCs are chemicals emitted as gases, and your body absorbs them when water is heated and vaporized.

VOCs – Health Effects
Eye irritation, Nose irritation, Throat irritation, Headaches, Kidney damage, Liver damage, Central nervous system damage, Allergic skin reaction, Dyspnea, Fatigue, Emesis, Epistaxis, Cancer

Mercury:
A liquid metal that enters our water through landfill runoff, cropland runoff, erosion of natural deposits, and discharge from factories.

Mercury – Health Effects
Brain damage, Kidney damage, Vision and hearing quality decrease, Memory problems, Irritability

MTBE:
MTBE, which is short for methyl tertiary butyl ether, is used to reduce ozone and carbon monoxide levels from auto emissions in gasoline. It ends up in our tap water through spills, pipelines, discharge from engines, and seepage of underground storage tanks.

MTBE – Health Effects
Headaches, Nausea, Dizziness, Throat irritation, Liver damage, Cancer

Conclusion

While not as proficient as whole house systems, but not as limited as pitchers, under-sink filters provide an effective means to enjoy clean drinking and cooking water as they remove contamination from the water that runs from the tap to which you connect them.

Here, we have provided you with the best under-sink water filters at the moment, but before we end, we want to go through some of the entries among them so that you get a clearer picture of what system is most beneficial for your needs and expectations.
