Why My Reverse Osmosis Water Has Bubbles?

The RO water machine is a great way to get safe and pure water for drinking, cooking, and other purposes.

But if you’ve ever noticed your Reverse Osmosis water has bubbles, you may be wondering why that is.

Don’t worry; you’re not the only one. Most people who have a RO water softener installed in their homes will experience this issue at some point.

In this blog post, we’ll explore the causes of those tiny bubbles and how to get rid of them. Stay tuned!

Why does my reverse osmosis water have bubbles?

There may be various reasons behind trapped air bubbles like:

1. How long is the system been used?

The longer you have your water treatment system, the more time it has to collect minor contaminations in the membrane.

As a result, the bubbles will stick on the Reverse Osmosis membrane surface and won’t go away even if you’re running hard water through it.

To solve this issue, replace your RO membrane or clean it.

2. The more water contaminations in the incoming water, the more bubbles you get.

The bubbles are the contaminants in the RO faucet water supply. Replace your RO membrane or clean your whole system with a cleaning solution to solve this issue.

3. Low-quality water inlet pipe and tubing.

If your water inlet pipe is made of low-quality material, the contaminants will easily stick to the inside of your water tubing, which will cause bubbles and cloudy water.

Replace your whole RO with a high-quality water filter system to solve this issue.

4. The wrong way of installation.

If you have a complete RO system with a storage tank, your inlet water flow pipe should only send the filtered water back to the storage tank.

Otherwise, the bubbles will mix with filtered water.

Ensure your RO cold water system is installed correctly to solve this issue.

5. Low water pressure.

The pump will not push the incoming cloudy water through a membrane filter if the tap water pressure is too low.

As a result, your system will not filter as expected, and the bubbles will stay in your filtered water.

To solve this issue, make sure you have a high-quality pressure pump.

6. The wrong way of pre-filtration

Your water filter system may have the wrong types of pre-filters, which are not made for the contaminants in your incoming cold water supply.

As a result, the contaminants will be stuck in your pre-filter, which is not designed to filter them out.

Replace your whole pre-contaminant filter with the correct one to solve this issue.

How to get the air out of the reverse osmosis system?

If you have any trapped air bubbles problems, in your Reverse Osmosis water don’t panic! We will explain how to solve each issue below.

1. Replace your RO membrane;

2. Clean your whole system with a cleaning solution;

3. Replace your whole RO water filtration system;

4. Make sure you have a high-quality pressure pump;

5. Replace your whole pre contaminant filter;

6. Adjust the water pressure by adjusting your pressure pump.

How to properly maintain a reverse osmosis system for optimal performance?

  • Don’t forget the membrane of your water treatment system. It’s a delicate piece of equipment, so you have to handle it with care.
  • Ensure you’re not touching the membrane and wash your hands before touching it.
  • If there’s any contamination on the membrane surface, clean it with a cleaning solution. You can use a brush to scrub the Reverse Osmosis membrane gently.
  • Please do not use an abrasive material or other tools to damage the membrane.
  • Also, don’t forget to wipe off all cleaning solutions before starting your system again.
  • Do not try to use the membrane of your water purification system for too long.
  • If you still think it’s not in good condition, replace it with a new one.

Is reverse osmosis water good for you?

Yes, reverse osmosis water is one of the best kinds of pure water you can drink.

It will remove 99% contaminants from your cloudy water, even fluoride.

It will make your RO faucet water taste great and give you healthy minerals too!

So don’t worry about tiny bubbles or other water issues you may have in your Reverse Osmosis system; we’ve given you the best solutions.

Now it’s time for you to take action and enjoy your fresh, pure drinking water quality, the same as bottled water.

Tips on choosing the proper reverse osmosis system for your home or office

1. Make sure you have enough water in your area

2. Check the RO system’s warranty

3. Ensure that the return policy is good

4. Verify the quality of the filters used in RO water filtration

5. Make sure that the system has a membrane that is made from strong material

6. Whether the system purifies a wide range of contaminants or just a few

7. Ensure that the system is certified by local authorities and industry associations


1. What kind of water should I get?

Not all RO water purification machines can remove fluoride. So make sure that the system you’re choosing can remove fluoride.

In general, TFM recommends that customers choose RO water systems that produce water purified from more than 99% of all contaminants.

2. How much water can my system produce?

It depends on the capacity of your membrane, water flow rate, and system configuration.

As a general rule of thumb, a 5-Stage Reverse Osmosis System with 40 to 100 psi can produce up to 20- 80 gallons of purified drinking water per day.

3. How often do I have to change filters?

The filter has an average life of 3 to 4 months and depends on your hard water quality. Usually, the more contaminants are in your incoming tap water source, the more you will have to change filters.

Clean it once a month if you want to make your RO system last as long as possible. You can use a cleaning solution to ensure that you have clean membranes.

4. How often do I have to change the membrane?

Usually, the membrane has a pretty good lifespan as long as it’s well-maintained, and it can last up to one year or even longer.

You can use a cleaning solution to ensure that you have clean membranes.

5. How can I reduce the amount of space my RO system takes up?

There are some Portable Reverse Osmosis Systems available on the market, and these systems are smaller and can fit under your sink.

So you have more space on top of your sink, and you can also take the system with you when you leave your house.


It is essential that you take care of your RO water softener to remove 99% contaminants from cloudy water, even fluoride.

Please follow the instructions in your user manual to ensure that you have clean RO membranes.
