In the United States, most households use water from a public utility company. It is typically stored at a reservoir and piped to a treatment facility, many of which use a reverse osmosis water filter system as one step of their complete system.
One of the problems is that to provide “safe” drinking water, treatment facilities must disinfect water that has been sitting in their tanks or reservoirs. The most commonly used disinfectant is chlorine. Chlorine is also added to the water to protect the membrane or the reverse osmosis filter from rot and algae growth.
Chlorine is a chemical that at one time was believed to be safe for human drinking water, but more and more studies are linking the chemical to cancer and other health conditions.
Chlorine is not the only contaminant in the water. The list of chemicals and other contaminants that have been found is longer than this article, but it is one that a reverse osmosis water filter does not effectively remove.
Chlorine makes your water smell bad and tastes bad. It’s not safe to breathe the chlorine vapor that builds up in the bathroom during a shower and, of course, it’s not safe to drink.
Knowing this, people look for home water purifiers and they see the highly advertised Pur water filter. If your water comes from a well, instead of a public reservoir, the water might not contain chlorine. Therefore and a reverse osmosis filter is the best purification system against contaminants. These contaminants could include Sediments or Rusts, Microbial Cysts.
But since majority of the population use public utility water, the water has already passed through a reverse osmosis filter. Most public utility companies use a reverse osmosis system during one step of their operation. The system removes contaminants and chemicals, organic and synthetic organic pollutants such as pesticides, agricultural runoff, and household cleansers.
So in this article, we take a closer look at reverse osmosis water filter and Pur water filter.
Pur Water Filter vs Reverse Osmosis
The difference between activated carbon filters and reverse osmosis water filters is the method of filtration.
The reverse osmosis system filters particles depending on their relative molecular size. Due to their relative bigger molecular size compared to chemicals, the minerals and metals get stuck while the chemicals flow right through.
Activated carbon filters bond chemically with the organics and synthetic organics which come from pesticides, agricultural runoff, and household and industrial waste, thus not allowing them to pass through into your glass.
There are a lot of questions regarding reverse osmosis water filter systems. So let’s take a closer look at how reverse osmosis works and PUR water filter and their pros and cons.
Reverse Osmosis System
One of the problems of using well water or if your source of water is a river, is the Acanthamoeba, a microscopic organism that can cause illness and death. This organism enters the body through the skin or the eyes or through tiny scratches or scrapes infecting the entire body.
You’ll need a micron filter to keep yourself from Acanthamoeba, microscopic organisms, and bacteria. A quality Reverse Osmosis Water Filter system will effectively remove these microorganisms and other contaminants.
A reverse osmosis system is used in home and commercial filter systems to produce filtered water as essentially pure as distilled.
So the how does reverse osmosis system works?
How Reverse Osmosis Works
Water under high pressure is forced through several porous membranes. These membranes are semi-permeable and eventually allow only “pure” water to pass through. Anything heavier or molecularly larger than the water is removed. Anything smaller or lighter passes through with water.
A multi-stage Reverse Osmosis system includes a 5-micron sediment filter to trap sand and rust, a 5-micron activated carbon filter to filter free chlorine and other substances that can affect the odor and taste, a 5-micron carbon pre-filter to block free chlorine from entering the RO system, and the RO Membrane which completely removes dissolved solids such as sodium, perchlorate, chromium, arsenic, copper, and lead. GAC is the final filter that filters the water used as it leaves the storage tank on its way to the faucet.
In kidney dialysis machines the reverse osmosis filter is used to clean the blood.
Reverse Osmosis filter systems provide the purest drinking water and the safest, demineralized water without the concern of corrosive chemicals, heavy metals, or pharmaceutical residues for use in machinery and household and kitchen appliances.
Due to this, reverse osmosis filter systems can lengthen the life of kitchen appliances by filtering out chemicals that can clog or corrode metal, plastic pipes, and tubing downstream from the RO system.
The reverse osmosis water filter was designed for large-scale operations, industries that require mineral-free water, and for people traveling in outlying areas without public water. Film development, for example, requires de-mineralized or distilled water.
Studies have shown that drinking water without minerals is bad for the digestive system. Without these calcium and magnesium, the pH of the water will change. The reverse osmosis water will taste like dead water.
The water will turn from alkaline to more acidic. Acidic water can have several unhealthy consequences with prolonged use. Re-mineralization is thus necessary when a reverse osmosis filter or distillation is used.
But, there are even more disadvantages to a reverse osmosis filter in the home. Reverse osmosis water filter systems are expensive and inefficient. They cost more initially and they cost more to maintain.
They waste more water than they clean. The amount of water wasted will depend on which reverse osmosis filter you choose. But, the most effective ones waste the most water. On average, about 5 gallons are wasted for every one gallon that is cleaned. If your water is free, then maybe that’s okay, but for most of us, that’s not the case.
Reverse osmosis filters require electricity to work properly, thus higher electrical bills. It also requires pressure and a pump.
The membranes are difficult to replace and prone to manufacturing defects. The size of the pores determines what contaminants will be blocked. The molecular size of chlorine, for example, is small enough to pass right through the pores. Microscopic bacteria referred to as cysts will also pass through.
So what is the alternative? PUR water filter is a technologically advanced system is that uses an activated carbon-based filtration system to removes harmful chemicals while leaving minerals and natural metals intact.
Pur Water Filter System
Public utility companies hold that the level of free chlorine used in the treatment plant is safe for human consumption, but more and more researchers are questioning that. This means that we need to deal with the free chlorine ourselves, at home. The reverse osmosis water filter will not effectively remove chlorine.
PUR Water Filters have created a convenient, easy-to-use home water filtration system that works very effectively. These water filters are NSF-certified to decrease chlorine, minerals, and major microbiological contaminants at an affordable price.
Pur water filter, without any doubt, is supposed to be stand amidst the top-rated water filters present in the market. Drinking water from a PUR Water filter promotes more hydration. It also improves our cognitive function and even brain performance.
Since we are drinking water without harmful chemicals, we have good reason to believe that our digestive health is improved. Besides, water also improves the condition of the heart.
Beyond the health benefits, you also save a lot of money by not spending it on bottled water. Using a PUR Water Filter is easy. It takes only a few minutes to assemble and installed no tools are required.
Once assembled and running, there is built in indicator to alert you when you should replace the water filter.
PUR water filters include a chart that shows the reduction or removal of unhealthy additives.
What is nifty about the Pur water filter is that it can reserve seven to eight glasses of filtered water and you can push the button to flavor the glass you were drinking, but the residue of the water was unflavored. You still have the clear filtered water, yet push a button and you have a fruit-flavored drink.
The flavor packet built inside has no added calories. The fewer calorie alternatives to juice provide you with different fruit flavors, but still, give you water that has been treated with chemicals.
PUR water filter replacement cartridges are easily found in the market. They are also cost-effective. So here these are some of the best PUR water filter replacement cartridges in the market today.
PUR RF-9999-6 3 Stage Faucet Mount Filter, 6-Pack
These need to be used on PUR faucet filtering systems. The filter will need to be replaced after 3 months. Most contaminants in the drinking water are removed thanks to the activated ion exchange carbon and resin.
Chlorine, mercury, and lead are also removed. Apart from that, you can remove agriculture as well as chemical and industrial filthy agents from the water as well as any sort of sediment.
This PUR water filter replacement product comes as the 3 stage product, which means that it is going to clean the water by removing contaminants permanently, makes it healthy.
The final step gives the water a fresh and clean taste. The product is also conveniently priced.
This is a two-stage water filter, which and has 3 filters in one pack. They can be used in PUR Ultimate Water Filtration Dispenser and Pitcher.
This water filter can remove 99.99% of the sediment-first stage — as well as removing asbestos, lead, mercury, and harmful bacteria in the 2nd stage. So if you are living in a region with plenty of industrial wastes in the water supply, this is the right PUR water.
How long do PUR filters last?
Typical the cartridges last 2 – 3 months or 100 gallons. PUR water filter has an indicator right on it that is so easy to use. The automatic gauge is standard on all PUR filters. The long-life is a huge selling point.
Practically, PUR Water Filters make sense.
The main reason for this decline in the liking of Pur water filters is their inability to get rid of various types of contaminants. These filters are especially effective for cysts, and microbes like giardia and cryptosporidium. It can eliminate 99.9% of microbiological cysts and cryptosporidium from the water.
But they cannot simply remove other contaminants like prescription drugs, pesticides, etc. These contaminants are extremely harmful to our health.
Pur also does not filter fluoride from the water.
Pur water filter still hasn’t found out a way to recover from plumbing line problem of scale expansion that guides to the unknowing consumption of hard, impure, and unhealthy water.
Mineral like magnesium or calcium are useful for human body and helps to build the skeleton.
Water is the driving fuel of the human body and yet it is ignored so much as to the extent that most people don’t even realize that the water they are drinking could be contaminated.
Whether we choose to employ the reverse osmosis system of the PUR water filter system or any other water filter, we all should recognize that we better ensure our drinking water is safe to drink.
