Is Filtered Water Good For Plants? [The Answer Might Surprise You]

Our quest for a cleaner diet and a healthier life has led many of us to grow our own or potted herbs, add them to our meals, and even experiment with urban vegetable gardens.

Aside from looking great, indoor plants and herbs also help us to feel good when we're in our homes.

We must ensure that we take the best care of our plants if they help us become a healthier and happier version of ourselves.

Drinking unfiltered tap water is beneficial to humans. In addition, it also helps plants grow healthier. Furthermore, drinking filtered tap water will make your skin look younger and healthy. But is it good for your beloved plants too? We are wanna find it in this article-

Filtered water - what is it?

Drinking water is treated with a variety of technologies to remove contaminants.

Activated carbon filters are used in pitcher filters, under the sink or whole-house systems, while reverse osmosis utilizes in under-counter or whole-house systems. Water can be filtered in four primary ways:

  • Environmental Protection Agency (EPA) recommends activated carbon filters in pitcher-type filters, as they bind to contaminants and keep them from flowing through to your cup. This method might not remove bacteria and arsenic, but it removes some metals and visible sediment.
  • Water can be softened and demineralized using an ion exchange system. It is not commonly used to remove unhealthy toxins.
  • Molecular filtration by reverse osmosis (with carbon): Dr. Singh recommends this method based on carbon and tight membranes. As well as removing bacteria, viruses, and common chemicals, reverse osmosis can remove certain chemicals.
  • A distillation process involves boiling water into steam, then condensing it back into the water. Steam contains contaminants that remain trapped in the original container. As the water cools, bacteria can recolonize. Distilled water is very effective, but it is sometimes difficult to eliminate them.

How does filtered water work?

In nature, the filtering of water is a normal process. It cleans and purifies water as it moves through the world. The same thing happens in our homes with reverse osmosis systems.

Water passes through the membrane or filter, which removes impurities from the water. This purified water goes to your home’s plumbing system and continues its journey into your sink, shower, tub, and toilet.

We must first understand how water works to eliminate all these impurities.

Water molecules come together to form hydrogen bonds. These bonds allow the water molecules to hold onto each other and create a network structure. When hydrogen bonds break down, the water molecules lose their structure and become free to move around.

When the water molecules are free, they start moving around in any direction. They flow like water would if there were no obstacles in the path.

When the water molecules collide against something solid, they stick to that object. Therefore, the water molecules cannot pass through solid objects. That is why the water comes out clean and clear when you turn on the faucet.

However, when the water molecules hit another molecule, they bounce off and continue moving. Their movement creates friction, which causes heat. If the water hits too many other particles, it becomes so hot that it boils. As water molecules break down, they destroy.

However, water does not boil at room temperature because hydrogen bonds hold the water molecules together. In addition, hydrogen bonds prevent the water molecules from breaking apart.

This is why water is an excellent conductor of electricity. Electrons flow easily through the water molecules, creating a current.

Water molecules also conduct heat quickly. So when we use cold water to rinse off dishes, we are heating up the water molecules.

Because water has such amazing properties, we use it for everything: cooking vegetables, washing clothes, cleaning the house, drinking, bathing, and even making ice cubes.

Now the real question is, is filtered water good for plants?

The answer to this question is yes. In no uncertain terms, filtered water benefits plants in every way. It is important to provide your plants with the best and healthiest life, and you will need filtered water.

Why is filtered water good for plants?

Even humans can taste and smell many unwanted chemicals and contaminants lurking in tap water even when plants cannot. This is because tap water typically contains chlorine as its main chemical.

To reduce bacteria, parasites, and other natural and synthetic contaminants in our town water supply, disinfectants such as chlorine add before the water enters our water distribution system.

Some negative effects are associated with ingesting chlorine, including the ability to kill viruses and bacteria in our water supply. There is also an overall bad taste and smell to the water that can cause asthma symptoms, skin irritations, and lung irritations in humans.

Plants can be harmed by chlorine, especially if it is present in high concentrations. However, it is important to remember that plants are also living organisms. Therefore, if you do not want to drink or wash with chlorinated water, you should also avoid watering them with it.

Plants can be harmed by more than just chlorine. There is a particular sensitivity to fluoride in plants. Dental health improves by adding fluoride to water. Soil, rocks, and air naturally contain this mineral.

Enamel can be strengthened, cavities can be prevented, and teeth can even be remineralized in order to restore the worn-down enamel; tooth decay can be reversed, and oral bacteria can be prevented from growing.

A burned or browned leaf is the best indicator that your plant is sensitive to fluoride, according to Gardenoligist.

Tap water contains fluoride, which is toxic to many plants;

• Spider plants

• Palms

• Dracaenas

• Peace Lily

• Bamboo

• Spineless Yucca

• Boston Fern

Which water is best for plants?

Rainwater and filtered water are the best types of water for plants to avoid harmful chemicals.

Rainwater sitting in a tank for a while can also be contaminated with sediment and parasites, and not everyone has access to pure rainwater daily. You should use a home water filtration or purification system to give your plants the best water possible.

In addition, a wide variety of home filtration systems are available to reverse osmosis purifiers and activated carbon filtration systems. They include neatly plumbed systems under sinks and simple DIY installation portable units.

Whether looking for a stylish and portable Bench Top Water Filter or a neatly installed Under Sink Water Filter system that works great to clear the clutter off your kitchen bench, Pure Water Systems has the right water filtration system for you. Carbon block technology is used in both systems for town water to ensure peace of mind.

No matter what you choose, Pure Water Systems has the right system to ensure that your garden, indoor plants, and herbs are happy and healthy.
