Technology: The purifier works on patented High Capacity 4 Stage Technology

Stage 1 – Five Micron Sediment Filter

The purifier comes with five micron gradient pore structure – which works two ways. The outer section traps large particles like sand and dust. The inner section acts as a second filter used for trapping the smaller particles of the same. The stage filter process is unique as it purifies rust particles too.

Stage 2 – Coconut Based Activated Carbon Block Filter

Harmful chemical residues and carcinogens are removed in the second stage. Cleaning of the water and removing foul odour from it is also done by this filter.

Stage 3 – Reverse Osmosis Membrane

The Reverse Osmosis Membrane of this purifier is a real advanced one and is NSF/ANSI 58 Certified! The company lists a number of harmful contaminants (provided at the end of the review) and claims to purify with 99 percent accuracy. Several reports on Zero Installation Purifier membrane suggest their claim to be true.

Stage 4 – Exclusive AlcaPure Post Filter

Calcium and Magnesium and some other essential minerals are required for our body. The RO membrane eliminates them and the 4th stage filter reimburses them in the water back again. This is where the waters alkalinity is also maintained to a perfectly balanced level of 7-8 pH.

Portability and Flexibility

As with all the other countertop ROs you need no installation for this machine which means no messy hoses or leaky diverter valves.

75 gallon of purification every day

The purifier is huge in regards to the volume and capacity of water it purifier per day. The system purifies 75 gallons of water per day which is twice the capacity of other countertop water filters. The recovery rate is pretty effective – 50% (1:1) which is the best among the same range of reverse osmosis filters.

Efficiency

The machine uses only 24W of power which is less than a light bulb which means it saves a lot on your electricity bills. This feature makes it a very convenient model for carrying along in RV’s as electrical power has a lot of value in those vehicles.

Rating – 10/10

APEC specialises in purifiers. The company manufactures all kinds of water servicing machines, ranging from huge industrial purifiers to the small single user ones.

This one is a very popular mid range RO water purifier. Compact and sleek design makes it very portable. The horizontal shape is unique, because mostly purifiers and dispensers have a vertical built.

The purifier uses a 4 stage purifying system. The RO membrane goes down to 0.0001 microns. The first and second filter needs to be changed every six months, whereas the third and fourth lasts for at least 3 years.

Most of the contaminants are removed by the machine; however removing of chloramines remains a question. You need a Omnipure K2526-JJ for chloramines. The K2520-JJ filter installed in this product does not filter chloramines.

The machine does not have an alkaline addition feature too. If you want, you need to buy separate alkaline filter.

In general the machine uses high quality filtration components which protect and prolongs the lifespan.

Installation

The installation process is easy, but the only limitation is that it does not fit to all the faucets. If your sink has pull-out faucets, special size designer faucets and sprayer faucets then you need to change to a standard one.

Design

The actual purpose of this RO is to serve condos, motor homes, retirement homes, seniors, students & travellers and so is designed accordingly. You will not come across many ROs having a horizontal built. This one is! The reason is that it fits easily in vehicles and RCVs.

What is a Counter Top RO Filter?

A counter top RO filter is on the counter machine for purifying water, which needs not to be fixed. Before recently most of the systems were designed as under-the-counter units, commonly installed under a sink cabinet.

People who don’t have own houses had a lot of issue installing RO’s in their rented apartments. According to US rental laws, even a small modification in the house needs to be sanctioned by the owner, and installing a fixed under the counter RO required changes in the drainage and sink counter.

Other than the rent payers, a fixed RO was a hassle to even the hotel owners and people who give their houses for rent. Even college going students and single bachelors had to spend a lot many dollars just on the installation – after the purchase of the machine.

Then there a lot of frequent travellers, who just want to rent an apartment for a month or so – and buying a fixed a machine was never an option for them.

Counter-Top RO’s are the best possible solution, because they can be easily attached to new and existing faucets and no installation is required.

Secondly because the counter-top machines are small, compact and usually tank-less – they serve best if you want to carry them along on your short trips too. You are going camping, or just want to enjoy this summer with your family you can put them in your recreational vehicles and enjoy pure water through-out your trip.

But are – Counter-Top RO’s as effective ones as the fixed ones? Let us analyze the working of a counter-top RO.

How Does a Countertop RO Work? 

A counter-top RO system is highly effective in producing water quality comparable to the standards of under-counter RO systems, and if you are comparing bottled water, than this machine can guarantee higher standards and better quality. They are purer and fresher than bottled water (more on this later).

Once you purchase the system and it is delivered home – all you have to do is to connect it to a sink faucet through a faucet head adapter and turn the faucet on. This process is as easy as connecting your phone to its charger, and requires no technician. The good thing is that most of the counter-top RO’s fit to all kinds of faucets.

Once plugged in – open the diverter valve on the adapter. The water will be channelled through a tube away from the faucet and will flow through 3-4 different purification cartridges. A counter-top RO’s filtration process is very similar to a fixed ones filtration process.

The Stages of filtration are:

  • 1st Stage: Spun fibre removes sand, particles, dust, mud etc.
  • 2nd stage: Granular Carbon Filters chlorine, organics, odour, smell, turbidity, etc.
  • 3rd Stage: RO membrane removes bacteria, dissolved metals, chemicals, salt, other minerals, and other dissolved matter in the water.
  • 4th Stage: Post carbon filters dissolved gasses and any cleanses the water from foul smell and taste.

Modern counter-top ROs are highly effective in purifying the water, removing almost all the contaminants and adding back the required mineral back. And this is not all – as some purifiers even allow control over taste. You can choose the kind of taste you want – and can even have coconut water or rose water taste!

Some high end counter-top RO systems even offer alkaline water. They make the water basic – by adding organic bases. More alkaline water is extremely beneficial for the human body and is recommended for its health benefits.

Once the water has passed through all the above filters and the required minerals are added, you can open the tap and enjoy fresh, pure and healthy water.

But there is an important thing to note. Generally counter-top RO’s do not come with a storage tank. The water is purified in some seconds and then comes out of the tap. No stored water is available for instant use. If you want to store the water, then you need to do it in a separate pitcher or jug.

For single users and users on the go – this is not that big a problem but is an inconvenient feature for big families and house owners. However now manufacturers are offering all the features of a fixed under the counter RO – in counter-top RO’s. In fact you can get a RO machine which acts as a water dispenser – having cold and hot water dispensing provision.

Earlier Countertop RO’s were not fully automated. So you had to wait until the filtration progress used to get over and then manually turn off the faucet and the diverter valve. This was very time consuming and a hassle to use. So if you are planning to buy a counter-top RO, look whether it is manual or automated.

Because of the easy working, hassle free installation and almost similar features in comparison with a fixed RO system, more consumers including homeowners are inclined to buy a countertop system overlooking the option of installing a regular under-counter machine.

If you are trying to choose between these two types, below is a list (just key points) highlighting countertop system’s advantages and limitations.

Countertop ROs advantages and Limitations in comparison with Fixed ROs

Flexibility

Advantage – Countertop ROs are very flexible than the latter. They are compact so they can be easily carried too.

Most importantly the installation-free feature is a welcome benefit. The system is easy to install without tools or drilling required, so one can do it without any support, which again saves you a lot of dollars.

And the system attaches to any faucet head so that does not require you to modify you sink or sewage plumbing.

Limitation – Tank-less system makes the product a little inconvenient for larger families.

Secondly if the system requires manual operation than a lot of time gets wasted in switching the system off and on.

Maintenance

Advantage – Counter-tops are easy on pockets as they require less maintenance. With them leakage and plumbing issues are minimum.

Secondly the system uses disposable inline pre-filters which can be easily replaced and are hassle free. In addition to that the replacement of the filters does not require the housings to be replaced.

Limitations – The filters are inferior in comparison to the fixed RO filters. The maximum period they can support is 6 to 8 months. After that the quality of the water gets affected. In a fixed one you can stretch the filter to a year, and sometimes to 14 months.

Quality

Advantage – There is not a percents difference regarding the quality of water produced by both the machines. The water tastes same and has no contaminants like the fixed ones. In fact as the system is tank-less the users are subjected to instantly purified water.

Secondly the machines hardware is also rough and tough to support the portability and travel wear and tear.

Limitations – There are no limitations in regard to the quality of the water. The only issue you can face is the collapsing of the system if you have chosen a low quality machine.

RO Purifier Water VS Bottled Water

Water treatment by Reverse osmosis process was developed more than 40 years earlier – as a means of creating clean freshwater from saltwater. The available water treatment sources at that time were very expensive and consumed a lot of energy resources. Reverse Osmosis guaranteed the treatment at an affordable price and by conserving the energy resources too.

In spite of this history – There is a lot of misconception that bottled water is manufactured according to the highest purity standards, and hence is the healthiest of all the available sources.

But this is not 100 percent true. People spend a lot of money on it, especially corporate offices and public and private organisations. Especially when outside – bottled water is the only choice. Drinking RO water on recreational trips was never a fashion until recently.

Below are some points which provide end to end comparison between bottled, natural and RO purifier water.

Bottled Water:

  • It is manufactured according to guidelines set by the FDA, not the EPA
  • The test requirement for microbiological contaminants in bottle water plants in only once a week.
  • Elimination of Chlorine-resistant bacteria is not covered in FDA guidelines, and hence bottled water does not screen these kinds of bacteria.
  • Average manufacturers actually fill tap water in bottles and add some mineral salts (according to a study of 103 brands of bottled water). So basically bottled water is literally nothing but municipal tap water.
  • Contamination due to plastic containers is an unavoidable factor. If the water is bottled in any organic container, then the cost will rise to several dollars.
  • Bottled water costs an average of over $1 a bottle. Sometimes the cost rises to 5-10 dollars. An average $7 billion per year is spent on water in America alone.
  • Some studies claim that the risk of birth defects rise due to tap water as it is a contaminated source.

Natural Water

  • Ponds, lakes or any other surface or groundwater does not provide purity. The contamination does not stop – because these are natural sources.
  • A lot of medical problems are associated with drinking natural water from its source. The most common are kidney stone, diarrheic conditions and a sudden increase in blood pressures.
  • Natural water after being treated in a municipal water plant travels hundreds of miles of pipeline before reaching your home faucet. Just imagine the amount of contaminants present in the pipelines which can spoil the water.

Filtered Water:

  • Can be used in all household uses and provides cleaner and better results even when used for cooking, and dishwashing.
  • A study claims that filtered RO water removes 2,100 known toxins found in drinking water, some of the most harmful being chlorine and lead.
  • Filtration removes contaminants which are harmful to the body, incites diseases and are even affect cells on a molecular level.
  • Removes lead which can cause learning disabilities in children.
  • Removes fluoride which is the most used chemical additive municipality tap water. Fluoridation till this day remains a topic of debate its affects on human health.
  • Protects children’s developing immune systems.

So whenever and wherever you are, RO filtered water is the best available source for pure and healthy water. And water is life, so even while not at home you can always take portable RO filter system with you, connect it to a standard water supply and enjoy the best of the waters.
