If you ask me which household appliance is essential to my family, I would like to tell you that it is a reverse osmosis system which I use to get filtered water to drink, cook and wash. We cannot live without water and our body contains too much water. How to drink water healthily is very important. A reverse osmosis system is a water treatment device which we can use to purify water. Compared with other water treatment devices, RO water filter can provide us with plenty of pure and healthy water to drink and cook.
I hate tap water due to its bad smell and taste; I didn’t enough water every day before, even if I knew that drinking 64oz water at least per day is essential. After buying my best reverse osmosis system, everything has been changed. I have enough filtered water to drink and cook, as well as my wife and kids. I also don’t buy bottled water because the filtered water smells and tastes very well.
You may think there are so many types of water treatment devices and why do you need to purchase a RO system. This is because reverse osmosis is the most economic and effective way to purify water. Other types of filters, like water pitcher filters, active carbon water filters, water distillers, or refrigerator filters, aren’t able to effectively remove most main contaminants in our tap water.
The reason I don’t drink bottled water is that RO filtered water is considered as the safest and most healthy water for drinking. Now I like to drink water and I can’t live with my best RO system.
Why do you need a reverse osmosis system?
- Our tap water contains many contaminants and our RO systems can remove them effectively.
- RO filtered water tastes and smells great as well as bottled water and we don’t need to buy bottled water because we don’t know what’s in the bottled water.
- RO water can make our drinks or food not contaminated and tastes better. For example, we can use RO water to cook tea/coffee or make juice for a better taste.
- RO water is also perfect for some appliances which need to use water, like irons or humidifiers. RO water can protect them and make them work more effective.
- Our pets or plans may also need RO water because of its purity.
Best Reverse Osmosis System
We’ve done a lot of research and have chosen the 5 best reverse osmosis systems available on the market. They are different from brands, stages and functions, but they are all high-quality and highly rated.
1.Home Master TMAFC Artesian Full Contact Reverse Osmosis System
Up to 98% of contaminants (like heavy metals, chemicals, sediments etc.) can be effectively removed by this RO system. The most impressive feature it is that it can restore essential minerals our body needs, like natural calcium, natural magnesium,etc. This filter is able to product about 2,500 gallons filtered water without replacing filters. What’s more, it also comes with a fast flow RO kit and this kit is able to make the water flow doubled when opening your faucet.Read Full Review
2. iSpring 75GPD 6-Stage Reverse Osmosis System (Alkaline Mineral Water)
This filter is an updated version of iSpring 75GPD water filter. As a 6-stage filter, it is a real RO Alkaline filter. The water from its faucet is PH-balanced water (alkaline water). Heathy minerals such as calcium, magnesium, potassium ions as well as sodium will be added back into the filtered water. These healthy miners are essential for our health and our body is able to 100% absorb them. This filter can work at a low water pressure as low as 45 PSI. However, if the water peruse is lower than 45PSI, a booster pump is necessary.
3. Home Master TMULTRA ULTRA Reverse Osmosis Under Counter Water Filtration System
This water filtration system is not only good for tap water but also perfect for not only tap water but also well water. If you live in a rural area and want a filter to purify your well water, it is the right choice. It is able to remove up to 98% of all kinds of contaminants, such as chemicals, heavy meats, sediment etc. It also can remove over 99.9% of bacterial and viruses as well as other microorganisms. It also has fast flow RO kit and an alert indicator which can remind you when to change your filter.
4. iSpring 75GPD 5-Stage Reverse Osmosis System
If you live in a low water pressure area, this RO system is your best choice, because it allows water pressure as low as 30 PSI. It is capable of removing all kinds of contaminants effectively. To my surprise, a luxury faucet that is free is also included for an updating. If don’t have enough budget to buy Tap Master TMAFC, you can buy a 5-stage RO filter like this instead. It deserves buying.

It is so easy to install that you can install it by yourself.
What is Reverse Osmosis?
Well, we should know what reverse osmosis is. Reverse osmosis water filters can effectively remove no matter organic matters or other dissolved solids. Generally, a basic RO system contains 3 stages of filters – a pre-filter, a semi-membrane (the key filter) as well as a post filter. The process is as the following: At the beginning, sand, dirt, silt as well as chlorine will be removed by the pre-filter. This process is also helpful to protect the membrane. Then the semi-membrane will only allow water to pass through but other contaminants (like heavy metals, chemicals and other contaminants) will be left on the other side of the membrane. This is the core process of a RO system and this process remove main contaminants in our water, making it distinguish from other different types of water filters. The waste water that contains separated contaminants will be Discharged to the sewer, while clean water will be stored in the water tank which is connected to your faucet on the countertop. Once you open your faucet, the stored filtered water will flow out of our faucet. Before that, the post filter will purify water again to remove odors as well as sediments.
Of course, membranes are the most important parts for RO systems, because they determine the ability to filter what types of contaminants in our water. Generally, most membranes that are used in commercial RO plants are made from polyamide, acetate and polysulfonate. And the membrane is only made up of a 100-micorn of support layer and a 0.25-microns skin. As a griddle, only water molecules are allowed to pass through the skin.
Generally, water has an amount of dissolved solids. The amount is a constant percentage of dissolved minerals in feed water. For example, if the TDS (total dissolved solids) is 400 ppm, the water purified water by a RO system may have 20 ppm or 40 ppm, which means Reverse osmosis methods can remove 95% or 90% dissolved solids in the feed water. Most RO systems are designed based on TDS of feed water. Of course, the lower PPM in purified water is better.
Well, if you want to have clean, healthy water to consume and want to pick up the best reverse osmosis system, the above top 5 best RO systems can help you quicly find water you really want.
