What Is A Water Filter?

The main purpose of a water filter, in a nutshell, is to provide you and your family with clean drinking water. A water filter can help you take care of undesired chemical compounds, organic and inorganic materials, as well as biological contaminants in your water. Although tap water is generally safe in the USA, it can still be an improvement to install a water filter in your home.

Over time, certain types of impurities commonly found in your water supply can take their toll on your and your family’s health. There are several benefits of getting a water filter in your home. It will improve your drinking water’s taste by removing chlorine and bacteria that often make your water taste flat or chemical, and will make it taste fresher and cleaner.

This will likely make you and your family drink more water, which is an added health benefit in and of itself. It can remove lead, which can be a toxic chemical to ingest over long periods of time. It will lower the amount of money that you spend on filtered water, since getting a water filter will eventually be much cheaper than buying a bunch of water bottles.

It will lower your chance of getting cancer by removing chlorine, which can cause rectal, colon, and bladder cancer. It will also remove harmful minerals, but leave the beneficial minerals that will be good for your health. It can also remove bacteria that can cause an upset stomach, which is especially important since new evidence is now showing there is a significant link between your stomach bacteria and your mental health.

Getting a water filter for your home can be a great thing to do for both you and your family. However, it is important to know which type of water filter to get, and which would be the best option for your household. There are several different types of water filters, but by far the most popular seems to be a reverse osmosis water filter.

What Is A Reverse Osmosis Water Filter?

As mentioned above, reverse osmosis water filters are the most popular types of water filters. As the name suggests, a reverse osmosis system filters your water by pushing it through a semipermeable membrane, called the RO membrane, or the reverse osmosis membrane. Your water goes from the concentrated side (the one with the most contaminants), through the reverse osmosis membrane and into the less concentrated side.

The water that remains on the concentrated side is called the wastewater or the brine and the water that comes through to the less concentrated is called the permeate. The reverse osmosis membrane filters your water through small pores, through which water molecules can pass through, but not contaminant molecules. This is how this type of water filter achieves a very efficient level of filtration that earns its place as the most popular type of water filtration system. Reverse osmosis water filters also boast both a pre-filter and a post-filter for more accurate filtration. The pre-filter removes sediment and chlorine and the post-filter that polishes the quality of the drinking water.

What Is An Under Sink Water Filter?

An under-sink water filter is a type of water filter that is point-of-use (POU). This means that it is attached directly to where you need it (it connects right on your waterline), be it a kitchen sink faucet, a fridge water dispenser (with the refrigerator kit that can be acquired separately). An under-sink filter is one of the most popular types of water filters because it is a more budget-friendly option to whole house water filter systems, and it is a more space-saving option than countertop systems. Most people do not have a need for filtered water for their showers or to wash their dishes and their clothes, so an under-sink system is usually preferred if all you need is good, clean drinking water and nothing else.

What Are The Pros Of The WaterChef U9000 Premium Under-Sink Water Filtration System?

The WaterChef U9000 Premium Can Filter Through Several Contaminants

The Waterchef U9000 is a very powerful filter. It can get rid of an impressive 50 contaminants. This includes VOCs (Volatile Organic Compounds), chlorine, chloramine, pesticides, herbicides, arsenic, cysts, as well as 99% of lead, one of the most toxic contaminants found in drinking water. It does this at a flow rate of 0.75 GPM.

It does not, however, filter out fluoride. Some people are concerned about fluoride in the water supply, but overwhelming evidence shows that it is actually good for you. It was added to the US water supply in the mid-1940s to help prevent tooth decay, and since it was added, dental issues in the United States have definitely decreased. Nowadays, with the invention of fluoridated toothpaste and other dental products, there is less need for fluoride in the water, but it has not been shown to have any real health implications.

It does, however, make sure to add essential minerals back into your drinking water, such as calcium, magnesium, and potassium. Both of these minerals can be good for your health and can improve bone strength, mood, immunity, blood sugar regulation, and sleep quality. These are, however, the minerals responsible for hard water, which might harm your pipes and water-based appliances. If you do find that you have an issue with hard water in your area, you might want to consider getting a supplemental water softener that can take care of this issue and prolong the life of your pipes and appliances.

The WaterChef U9000 Premium Is Certified to Both NSF And ANSI Standards

Both the National Science Foundation and the American National Standards Institute are organizations that provide certifications to not only water filters, but different types of home water treatment systems also, such as water softeners, water ionizers (alkaline machines), fluoride filters, and many others.

The National Science Foundation is an independent federal agency created in 1950 to promote the progress of science; to advance national health, prosperity, and welfare. The American National Standards Institute is a private non-profit organization that checks the development of voluntary consensus standards for products, services, processes, systems, as well as personnel in the United States. The fact that the WaterChef U9000 is certified by both these organizations is an extremely good sign and makes this product much more transparent and reliable.

The WaterChef U9000 Premium Has A Fantastic Design And Great Quality Build

The WaterChef U9000 is designed with a complete stainless steel filter housing, which not only means it will last you longer than other types of water filters, it also means it will break much less than other products on the market. It also makes for a much more attractive product since the stainless steel gives it a polished and modern look.

You are also allowed to choose different colors for your filter in case you would like to personalize it. You will not be able to really see the filter once it is installed, since it will be installed within your water line, but it is always nice to buy an aesthetically pleasing product.

This water filter is also fairly small, at least smaller than other similar products on the market. This means that it will save you space in your kitchen and make sure you can place it wherever you would like, even if there is little space for it. Additionally, this WaterChef water filter also has a temperature range of 34 to 100 degrees Fahrenheit.

The WaterChef U9000 Premium Boasts Big Block Filtration Technology

The Big Block Filtration Technology that they have added to this product makes it so that the WaterChef U9000 is one of the best water filters on the market in terms of performance. This means that you will have great-tasting water as well as better-smelling water.

The WaterChef U9000 Premium Features An Intelligent Monitor

Yet another fantastic added feature to the already great WaterChef U9000 is its intelligent monitor that you can install on your designer faucet, or any regular faucet as well. This little piece of technology will let you know when it is time to change the filter, so you will not find yourself drinking contaminated water by mistake or doing guesswork about when you might need to change them out. The indicator light will let you know when it is time to change it by showing a red light. If the light is green, then the system is alright and does not need filter replacement.

The WaterChef U9000 Premium Boasts Low Maintenance Costs and High Durability

Due to this water filter’s fantastic construction, there is quite little maintenance needed for this system. Point-of-use (POU) filters, although small and compact, sometimes require a fair bit of maintenance. Their small size often means they need regular replacements over the span of one year. Most filters on other products usually need a cartridge replacement every 300 to 500 gallons or every six weeks.

The WaterChef U9000 is much more durable than others on the market, however. Their filters are made to last one year at the very least, so you will only need to buy one set of replacement filters per year, which considerably lowers the cost of maintenance for this great product.

The WaterChef U9000 Premium Has A Large 1000 Gallon Capacity

Even though this water filter features only one filter cartridge with a solid carbon block, with a proprietary blend of additional filter media, it can still get through up to 1000 gallons of water. This is on par with the advertised filter duration of 1 year, and is a much higher gallon capacity than most other carbon filter products of this kind on the market.

The WaterChef U9000 Premium Offers A Lifetime Warranty

The Waterchef U9000 also features a very generous lifetime warranty. This shows you just how much confidence they place in their product that they are willing to provide you with lifetime assistance in the off-chance that you might need it. Additionally, there is a 60 days cash-back guarantee in the case that you are delivered a faulty product by mistake.

The WaterChef U9000 Premium Is Delivered To Your Home

You can have this product delivered directly to your home by ordering it on Amazon.

What Are The Cons Of The WaterChef U9000 Premium Under-Sink Water Filtration System?

Really, the only problem with the WaterChef U9000 is that It does not filter mercury, bacteria, and asbestos. This can be an issue if your water supply has particularly high levels of either of these water contaminants since they can cause harmful health effects to you and your family.

Mercury is a naturally occurring metal that can emerge either from the natural degassing of the earth’s crust or the combustion of fossil fuels, as well as other kinds of industrial release. This kind of contaminant, in high levels and over significant periods of time, can cause damage to your brain, your kidneys, as well as developing fetuses. It can cause you to become a more irritable person, it can give you shyness tremors, and it can affect your vision and your hearing, as well as lead to memory problems.

Although bacteria are found everywhere in the environment, high levels of them or incidence of the kinds that can make you sick can really harm your health. Bacteria in your drinking water can cause you to have diarrhea, vomiting, muscle cramps, nausea, headaches,  fever, fatigue, and even cause early death sometimes.

There are groups that are more at risk for these types of issues, such as infants, children, elderly people, and people with weakened immune systems. You can read more about the harmful effects of bacteria on the Minnesota Department of Health website. Asbestos naturally-occurring fibrous silicate mineral that gets into your water through your pipes.

Between the 1930s and the 1970s, water pipes were built with cement, which included asbestos in its construction. As these begin to crack over time, the asbestos is able to get out and infect your water supply. Asbestos is a highly toxic element that can cause malignant mesothelioma, asbestosis, and asbestos lung cancer, among other dangerous diseases.

The WaterChef U9000 Premium – Is It Worth It?

The WaterChef U9000 can be an absolutely fantastic product to get if you are worried about your drinking water and you want a good, high-quality water filter that will not take up much space in your home. The only situation in which this water filter might not be the ideal choice for you is if your home has a high occurrence of mercury, bacteria, and asbestos.

Thankfully, it is possible for you to find out what kind of contaminants are in your water supply and how many of them there are. There are several different types of tests that you can do yourself in your own home without having to call your county’s health department or a state-certified laboratory to go through this process for you. Here are some of them.

Test strips are a cheap and convenient way of checking for water contaminants.

Test Strips

As the name suggests, there are small strips that you can use only once and test for the concentration of one specific chemical. All you need to do is get a water sample, dip the test strip into it, swish it around for a little bit, and wait. After you have waited for a little, you can take the test strip out, which will change color depending on the concentration of this chemical in your water. Then, you can refer to a color chart that will tell you just how much of that chemical there is in your water. These are the simplest tests to use, although they are also the least accurate.

Color Disk Test Kits

These kinds of tests, called the color disk test kits, can test for a wide array of chemicals. To use this specific type of test, all you need to do is get a water sample in a plastic tube. Then, all you need to do is add the powder packet or drop a few drops of the liquid reagent. At this point, you will be able to place the plastic tube in a small plastic viewing box that will have a plastic disk with a color gradient printed onto it.

The kit itself will tell you how long to wait to get the most accurate color on the sample. You can rotate this disk in order to find the color that best matches the one in the sample, and from then you will be able to tell how much of a specific chemical is in your drinking water. These are more complicated test kits to use, and they are also a little bit more expensive than test strips, but they are much more accurate in the end.

Hand-held Digital Instruments

There are several different types of hand-held digital instruments. There are lightweight and portable digital meters, there are colorimeters, and there are photometers. Out of all the three testing methods, these are the ones that provide the most accurate test results, but they are also unsurprisingly the most expensive as well as the most complicated to use.

They require the use of batteries and calibration, so they are usually only recommended to certified field technicians that use them for the regular testing of water supplies for counties’ health departments. If you are inexperienced with these types of machines, you might want to go for one of the two testing methods mentioned above.
