RO4000 Benchtop Reverse Osmosis Water Filters - Product Spotlight

In this article, we are going to look at three Benchtop Reverse Osmosis Systems currently known as the RO 4000 Range.

The difference between the two models is that the second model has an alkaliser cartridge on the top to bring the pH back up to neutral.

 

In this video, we take an in-depth look at the two models of the RO 4000 Benchtop Reverse Osmosis System, including the standard version and the upgraded model with an alkaliser. Learn how these systems filter your water in stages, from sediment removal to carbon filtration, and how the alkaliser adds beneficial minerals, raising the pH for healthier, more alkaline water. Whether you're after pure, pH-neutral water or prefer the added benefits of alkalisation, find out which model suits your needs best.

Note: We have a 3rd version of RO 4000 which is the RO 4000 Benchtop Reverse Osmosis Water Filter System with American Alkaline.

What’s Inside The Box?

The RO 4000 has 4 cartridges inside the box, no different to any other RO System except that the RO 4000’s are made with inline cartridges so they're just a bit different to other under sink RO systems that you might have seen before.

Inside the box of both RO 4000 models, they're both exactly the same.

How It Works

The diverter connects straight onto the kitchen sink tap. You turn the water on, the water flows into the sink like it always has. You've got the little lever on the side that you lift up when you want the water to flow into the RO system. The water will stop pouring into the sink and it will push the water through the pipe and into the RO 4000.

Stage 1:

The water first flows through a sediment cartridge that takes the lumps, bumps and dirt out.

Stage 2:

Then it goes through a carbon cartridge, taking out the chlorine and the chemical load in the water. It also protects the membrane in stage three.

Stage 3:

The RO membrane then splits the water into clean water and wastewater, sending the contaminants to waste and the clean water to your tap.

This is where the Reverse Osmosis membrane filters out organic and inorganic compounds such as fluoride and heavy metals. This stage will also completely strip the water from Total Dissolved Solids (TDS) like sodium, calcium, magnesium will be reduced to near 0.

Once the water goes through the membrane half of the water will go down the drain (black pipe), and the other half will continue to the next stage.

Stage 4: 

Once the water comes out of the membrane, it goes through the last carbon to polish the water up.

Reverse Osmosis Creates Acidic Water

Drinking 6pH water will flush the body out.

It’s okay if you know you need to consume acidic water for a specific purpose, perhaps to detox.

If you've been to the doctor and that was his advice, you may come for one of these and give yourself a good clean-out.

The health professionals all insist that the only water you should be consuming is of a neutral pH or higher. Read more about Why Your Water Should Be In A Healthy pH Range.

The RO 4000 with Standard Alkaline includes an Asian Alkaliser (lasts up to 1 year) while the American Alkaliser is made from USA Omnipure (lasts up to 2 years). Both cartridges sit on the top of the system.

As the water comes through the alkaliser cartridge, it will elevate the pH again, the water that flows out of this system flows out at around 8.5 pH. It might even be 9 pH when it's new.

Flush Valve/Flow Restrictor

If you ever get any muck in the pipe of your Reverse Osmosis RO 4000, you can hit the flush valve button and it pushes water through.

Flow Rate and Water Storage

Reverse Osmosis systems are very slow at creating water. You’ll notice a flow rate of about 200ml per minute and most under-the-sink systems will have a tank to store the water in as a backup. The RO 4000 on the other hand, doesn’t have a tank, so owners need a bottle or a jug to store their water.

Flexibility

These are great little systems too for putting in the laundry.

You can get a simple laundry connection and just cut the diverter off the end, and plug that pipe into the 3/4 inch washing machine adaptor. So the washing machine pipe still runs like it always has and we just put a little tap off to the side, and then we can get the water through the RO4000 and operating in the laundry if that's the best place for your system.

Summary

The RO 4000 has been around for years. It creates great quality water and we highly recommend it.

Our choice is always going to be the RO 4000 with the Standard Alkaliser.

There really is no better foundation for creating the best water you can with Reverse Osmosis, at such an affordable price.
