2018’s Best Reverse Osmosis Water Filters

2018’s Best Reverse Osmosis Water Filters

Water purification is quickly becoming an integral part in any household. Tap water has become less reliable either because of ineffective treatments processes or extensive chemicals. It has made tap water no longer viable from a hygiene perspective. It also raises health concerns. This is why having access to purified and safe drinking water has become very important today. When you use a reverse osmosis system, it does exactly just that. It delivers pure and safe drinking water. So if you are now convinced and in the market for one, read on to find out which reverse osmosis water filter is best suited for your needs.

What is a  Reverse Osmosis System?

To further appreciate what it does, let us explain what this system really is. A reverse osmosis system uses a tested, pump-driven high-pressure system that converts tap water, brackish or sea-water into potable water. This contemporary water purification system uses the same principle found in nature, only in reverse(hence the name).

What are its uses?

Reverse osmosis systems are used to successfully treat water in various conditions like desalination of sea water, purification of brackish water, conversion of waste- and tap- water into clean and safe drinking water. A reverse osmosis system is also one of the water purification systems that uses the least energy.

A reverse osmosis system can be used to purify water from:

  1. Waste-water – Purified even the worst waste water, including even industrial waste.
  2. Salt water – It successfully purifies ocean salt water into potable water.
  3. Tap water – Capable of purifying typical tap water.
  4. Brackish water – Reverse osmosis system can even purify brackish water.

So without further ado, here are the best reverse osmosis systems of 2018.

Now that you know which RO systems to go for, here’s an in-depth explanation on what features to look for when shopping for a reverse osmosis water filter.

Factors To Consider When Buying a Reverse Osmosis Water Filter

Wasted Water – Before we talk about this, let’s clarify the common misconceptions about the amount of water that is wasted in Reverse Osmosis filtration. When using sea water, there will naturally be high amounts of salt and other sediments. Filtering sea water will have a significant amount of water “wasted” to flush the membrane, but these are for large, commercial uses. Remember that the filtration systems in our guide are designed for home use. So it is significantly more efficient. Also, with improving technology, the amount of water needed to flush the RO membrane will decrease. So if you are questioning if the benefits outweigh the small additional cost of wasted water, then don’t. When choosing a system for you, check the water costs in your municipality and if see they are high enough to make an impact. If they are, you may want to go for a more efficient unit.

pH Levels – Reverse osmosis systems are designed to work with water of almost any pH level. Keep in mind that most public water supplies have neutral pH levels of around 6.5 – 8.5. As a general rule, reverse osmosis systems will make water slightly more acidic because they lower the pH value of the incoming water. Also, since the pH level will be lowered, the resulting water might have a taste that you’re not used to because most of the minerals have been removed. Fortunately, there’s a solution for that. You can use a remineralization system. This system will change the taste of the water and put the exact minerals in the water that you’re looking for.

Installation – Some systems are easy to install while others are complicated. That’s why the ease of installation is also another important factor that you should take into account when choosing an RO system. Ultimately, it will rely on whether or not you are comfortable installing it on your own to save on additional expenses or if you have the budget to hire a professional to do it.

Taste – The taste of the purified water is another big consideration that you need to look at. A good RO system should produce purified water that doesn’t alter the taste too much. After all, you will be drinking and using this water to cook. Luckily, these systems are designed to remove impurities that will affect the taste of the water, you will be ensured that the taste won’t be that. It is up to you which system produces a taste that you are comfortable with.

Stages – Most RO systems have a 7-stage purification process, but not all systems have all 7 stages. The good news is, it isn’t very critical for the quality of the water. In most cases, 5 stages are ofen enough for your needs, unless you have a personal reason for wanting all 7.

To give you an idea of the 7 stages, here’s a list. Keep in mind that this is universal.

Stage 1 – water passes to a filter that traps sediment to eliminate silt, dust, and large particles.

Stage 2 – a carbon filter removes odors, bad tastes, mineral oil and chlorine.

Stage 3 – additional carbon filter removes any remaining odors, bad tastes, or chlorine.

Stage 4 – This is where the reverse osmosis process happens. The water is pushed to a fine filter that removes around 95 percent of the remaining impurities like fluoride.

Stage 5 – With the use of a polishing carbon filter, the water in the reservoir will not form a stale taste.

Stage 6 – This stage is where the water is alkalized. The pH level is adjusted to 7 or above with the use elements like calcium and magnesium.

Stage 7 – Lastly, a special filter uses UV rays to kill germs and bacteria in the water.

Total Dissolved Solids – Total Dissolved Solids or TDS for short, is a measurement for the amount of sediments in drinking water. Sediments like magnesium, potassium, chlorides and sulfates and other organic matter are generally harmless, they are measure nonetheless to keep a standard. The EPA’s standard for a failing TDS score is 500 mg/L of water. The best RO systems can filter ip to 99.9% of these sediments.

How does a Reverse Osmosis System work?

With the use of extremely microscopic pores, an RO system will be able to filter out any impurity that is in the water. Although they are technically called “filters”, they are more like membranes because the pores are so thin that they allow only water to pass through just like a cell membrane. This leaves all the sediments behind, ensuring that you are getting pure water. All the pure water is then stored in a tank for consumption.

The great Reverse Osmosis filters can filter up to 99% of all contaminants in water. That is why it is very effective in turning even the most toxic and polluted water into pure drinking water that is safe for human consumption. Here’s a list of what an RO filter can filter out.

  • Phosphate: 97.1 – 99.8%
  • Arsenic: 98.4 – 99.9%
  • Lead: 99.1 – 99.9%
  • Iron: 98.4 – 99.5%
  • Fluoride: 94.5 – 99.1%
  • Chloride: 92.1 – 99.3%
  • Mercury: 96.2 – 99.5%

The downside of being able to remove everything from the water is it will also filter out essential minerals that are beneficial to you. Luckily, you can just add these minerals back in a mineral packet or an alkaline water machine.

Purification Performance of an RO System

There are a variety of factors that will affect the effectiveness of your reverse osmosis system. The RO system may underperform depending on the situation.  Here are some of the factors that can impact the performa

 nce an RO system:

Water Pressure – If there is insufficient water pressure to the RO filter, it may not be able to force the water through the membrane. This will result in a lot of wasted water.

TDS of Incoming Water – When there are more impurities in the water, there will be more stress put on the machine. This will result in replacing the filters frequently.

Temperature – In general, RO systems filter water best at luke warm temperature.

Quality – As always, you  get what you pay for.

FAQs

Is an RO system really needed for drinking water?

Reverse Osmosis systems are mainly used if your source of water is very impure or potentially dangerous. So, to answer the question, it is overkill for drinking water. If you want to improve the taste of your drinking water, going for a countertop water filter is a better option.

Is the water purified from Reverse Osmosis systems safe to drink?

The answer is a very resounding YES! Although it can sometimes result in lack of essential minerals, it isn’t inherently dangerous in any way. You may have to supplement some of the minerals you would have otherwise ingested from your tap water.

Can RO systems really filter even the most dangerous water sources?

RO systems are the most sophisticated systems for filtering water, so the answer is 99.9% of the time. There are very rare instances where an RO filtration is not acceptable. In these cases, you may want to use a water distiller. Keep in mind that this isn’t filtration, but it is able to produce 100% pure water. The only difference is it uses a significant amount of energy to produce.

What do the different RO stages mean?

Technically, reverse osmosis systems use membranes instead of filters. These membranes can remove sediments over 900,000 times thinner than a human hair. This membrane is usually used in one of the later stages of a Reverse Osmosis system. The first filtration stages work like your average water filter. Once it goes through the standard filtration processes, that’s the time where water is forced through an RO membrane. Advanced systems have an additional stage after the RO membrane. In this stage, it will usually use a UV light to remove germs and bacteria. Remember, the more stages, the more pure the water.

Do I need to do maintenance on my RO system?

Just like any piece of equipment, RO systems require maintenance every 6 months to 2 years, depending on how often it is used and the quality of the filters. Sediments will naturally build up in your filters over time. When that happens, the water will no longer pass through the stages at a reasonable speed, and will end up wasting nearly 100% of the water. That’s the main reason why you need to replace your filters every so often.  The good news is, the replacement process is quite easy and the water filters are quite affordable in general.

How do you install a Reverse Osmosis System?

Reverse Osmosis systems of the countertop and under-sink varieties, are very easy to install and do not require professional installation. All you need are some basic tools and a very basic understanding of where your incoming water pipes. There are numerous videos on YouTube and other sources that will show you step by step, how to install any model of reverse osmosis system.
