One of the cheaper water filtering solutions out there, yet a reliable one nonetheless as it even tends to the complete removal of total dissolved solids from the water you consume, the Aquatic Life is obviously one of our main recommendations for those who are on a budget and are seeking to drink only clean, pure water.
How Reverse Osmosis Works
The fact that the water we consume is not clean is not news to anyone, being no mystery behind the fact that each time we drink tap water we actually ingest a wide variety of contaminants. Although public water suppliers generally do their best to provide clean water for their customers, this does not happen due to a wide variety of problems, the water that comes out of the taps smelling and tasting bad, and being dangerous to consume.
Water filters use various types of technologies designed to capture certain impurities in the water. Reverse osmosis is one of the most popular technologies that are based on a rather simple process that occurs naturally. These filters include a semipermeable membrane that captures large molecules and particles from the water. Usually, a filter is paired with a sediment filter that retains sediments, rust, and calcium carbonate. In addition, these units also include an activated carbon filter that eliminates chlorine to prevent it from affecting the membrane. These combinations extend the lifespan of the RO filters and maximize their performance as well.
Provided Health Benefits
These water filters are gaining a rapid popularity due to their high efficiency and effectiveness. But with so many different types of water filtration methods out there, it can be hard to understand what makes reverse osmosis a great option to go with. To enlighten you, we will list the health benefits of drinking reverse osmosis water:
- Lead-free water
- No more cryptosporidium
- Removal of sodium
- Improved immune system
Lead is among the most dangerous contaminants that lurk in tap water, and unfortunately, it is mostly found in high numbers. Therefore, you cannot ensure that you will protect your health if you continue to consume this contaminated water. What makes lead a big enemy of your health is the fact that its consumption leads to problems with fertility, blood pressure, nerve damage, muscle damage, and even brain damage. But with the help of the filter, this won’t be an issue anymore as this type of system effectively removes lead from the water.
Cryptosporidium is a parasite that is found in contaminated water and that greatly affects the small intestines once it is ingested. Some of the unpleasant effects of ingesting it include diarrhea, cramps, and fever. Fortunately, reverse osmosis water is free of this very dangerous parasite, so you won’t have to worry that your health or the health of any other family member might be affected by it if you install this type of filtration system.
If you or any of your loved ones suffer from liver disease, kidney disease, or if you have high blood pressure, it is recommended to avoid consuming sodium. Unfortunately, sodium is found in pretty high numbers in the tap water that we consume, so you must find an effective solution to remove it. The best way to do this is by drinking filtered water because the filtration system that produces this healthy water removes the sodium molecules that it finds in the drinking water.
There are a lot of people who have weak immune systems and who are at risk for infections related to waterborne contaminants if they do not ensure that the water they consume is clean. This is especially true for children as their immune systems are in development, being very dangerous for them to drink contaminated water. Fortunately, with the addition of this type of a filtration system, you won’t only protect your immune system and the immune systems of your loved ones, but you will actually help improve it as well.
Useful Buying Guide
There are certain traits that characterize a top rated reverse osmosis filter, and in this section of the article, we will cover more details about them. By doing this, we hope to give you a bigger chance of investing in a quality product. Therefore, if you intend to buy this type of water filtration system, check out the following lines to have a better understanding of what you should look for.
Water Production Rate
The first spec that you should check out when buying an RO filter is the number of filtration stages that it passes the water through. Top brands offer products that feature 5 to 7 filtration stages, but there are models that exceed this number, like the Crystal Quest 1000C THUNDER Series that offers a staggering 12 filtration stages. The reason why it is important for these systems to have many filtration stages that are actually effective is that, during the filtration processes, various contaminants that lurk in the water are eliminated, every stage handling certain types of contaminants.
The water production rate represents how much drinking water the system can produce in a single day, and it is measured in GPD or gallons per day. To ensure that the RO filter you are checking out is actually of a superior quality, the GPD values should range from 50 to 90. Just know that the water production rate that is displayed on the spec sheet of the product is rarely achieved as there are various other aspects that influence the final number, like the water temperature, the quality of the water that runs through the pipes, and the incoming water pressure. Therefore, the numbers will probably be a bit lower than manufacturers advertise when it comes to the GPD rating.
The reason why it is crucial to check the lifespan of the filters is that they are the ones that influence the maintenance costs the most. If you invest in a low-quality ROOR filter, expect for it to have cheap filters that have a short cycle life and that need to be replaced very often, meaning that you will spend a lot of money on maintenance work. On the other hand, if you invest in a top quality system like the Crystal Quest 1000C or the iSpring RCC7, the filters will require replacement so rarely that you won’t be inconvenienced budget-wise.
Some systems come with extra features that add to their performance and that make them perform better in certain situations. The extra features that we recommend you look for include a UV light, a remineralization filter, and a pressure pump. The UV light is highly effective at killing microorganisms of all kinds, removing contaminants like bacteria, algae, fungi, giardia, E-coli, and Cryptosporidium from your drinking water. The remineralization filter is useful as it adds healthy minerals back to the water that you consume when the filtration process ends. When it comes to the pressure pump, this extra feature is useful as it increases the water production rate and the system’s efficiency by feeding more water pressure into the filter.
Pros and Cons of RO Filters
As any other home improvement you might make, these filters have their good and their bad sides and it is best to learn more about each one before finally making a purchase. Otherwise, you might not be happy with your new water filter. Without further ado, let’s see what are their pros and cons.
Better tasting water
One of the perks of using it is the fact that it does not require any electricity like other filters might. The entire process is developed energy-free so you will not add any costs to your household bill.
If you resort to an RO water filter instead of buying bottled water, you will save a lot of money because it will deliver gallons of water for a few dollars. Also, the purchase costs are not as high as other types of filters that are more complicated and require more filters.
Without a doubt, you will manage to improve the quality of your water which will also influence how your food will taste. The process is highly accurate in removing impurities and harsh minerals so that the resulted tap water will be far more qualitative.
Compared to other systems that are more cumbersome to maintain, this one only requires you to remove and replace one filter. It is as easy as that and in a few simple steps, you will refresh your filter and prepare it for more filtering.
The biggest downside is that it takes more time to filter the water, compared to other filters. It uses water pressure to push the water through the media, which is not a fast process. This means you will have to wait more time for your water to come from the tap. If you need a large amount of water and you empty the filter’s tank, it will take more time to refill it.
Due to all the impurities in the water, the media can get clogged very often if you do not ensure proper maintenance. A useful tip to prevent clogging is to install a pre-filter that captures the larger particles in the water thus, keeping the RO cartridge cleaner.
Another unpleasant side is the water waste that occurs every time you use it. During the process, up to 20 gallons of water are wasted for every gallon of filtered water, which is not a convenient aspect.
As it is our top choice, it should come as no surprise that the performance in terms of contaminant removal provided by the Pelican Pro 6-Stage highly exceed industry standards. It can remove up to 50 different types of contaminants it encounters, utilizes 6 different filtration stages to provide these great results, and it requires maintenance work less often than you would expect – you need to change the pre-filter only once every year and a half, while the post filter needs to be replaced once every 6 months. But the system we must admit caught our eye the most is the Crystal Quest 1000C THUNDER Series which is not only reasonably priced and thus affordable to a wider range of customers, but that is capable of removing up to 500 different contaminants lurking in your drinking water. However, if you have severe water quality issues and there is a ridiculously high number of contaminants found in it, we recommend the APEC ROES-50 Premium 5-Stage or the iSpring RCC7 5 Stage 75 GPD that are able to remove up to 1000 different harmful particles.
