Why Is filtered Water Good for Plants?

Filtered water is good for plants because it is reduced from harmful impurities, and it would promote plant development.

It would reduce chances of attracting diseases, and improves the plant’s ability to absorb water from the soil. Additionally, it will help the roots grow, and the fruit to be flavorful.

– Reduced from Harmful Impurities

Hazardous impurities and pollutants are removed from water filtered during the purification process; using such water is thus healthy for your houseplants. Filtration through water filters removes chlorine, fluoride, and heavy metals, among other contaminants. 

Reducing Harmful Impurities


The effects of tap water on plants are that plants are susceptible to damage from pollutants that may commonly be present in them. In short, when you irrigate it, the soil will be facing better a type of water, and as a result of this the roots will not be damaged in any way. 

– Promotes the Development of Plants

The growth of plants is stimulated by water that is filtered. This water can stimulate the growth of plant foliage by delivering the vital nutrients and minerals necessary for their continued survival. It is important to note, however, that if the water is filtered through a reverse osmosis, which is also known as RO water filter system, the water may be too pure for plants.

This is because the RO process also removes essential minerals necessary for plants’ growth. Hence this water becomes highly pure for plants, and in the short run, when you use this chemical free water, the plant will have a better development and growth, which means you won’t worry about any health deterioration. 

– Reduces the Probability of Contracting a Disease

Tap water can include impurities that encourage the growth of pathogenic bacteria and fungi, which can lead to plant diseases. Filtration reduces the risk of developing diseases of this kind by eliminating the pollutants that may be present in the water.

Filtered Water Reduces Disease

This is the reason because in some cases, the water you are irrigating would be contaminated, and it may promote diseases, however, with filtered water, the case is far away from this. 

– Improves Nutrient Absorption 

When soft water is filtered, it can make it easier for plants to absorb water and nutrients, leading to greater plant hydration and growth. When you irrigate with this type of water, the soil will not have excess of harmful nutrients, as a result, the roots will have a better ability to absorb the necessary minerals from the soil, because now, the roots have been in a peaceful condition.

Nutrient Absorption for Plants

On the other hand, if you have tap water as your only source, what you must do is to just let this tap water sit still for a day in a bucket or a container and the contaminants will settle down at the bottom. This is an easy and natural way to purify water.

– Promotes the Growth of Root Systems

A plant’s ability to generate robust root systems is critical to the plant’s overall health and growth, and the formation of such systems can be aided by using filtered water. Watering houseplants with water that has been filtered is better in comparison to softened water when it comes to root health. 

Growth of Root with Filtered Water

With water softener on hard water, the amount of salt is increased, thus watering plants with this affect plants, their average water balance and the health of the roots. Now, after a small time of using this irrigation system, the roots will have a more nourished state, and your plant’s growth will also change. 

– Improves Flavor

The act of filtering water can also improve the flavor of the water, which is vital for plants like orchids and terrarium plants that must have pure water to grow. Bottled water is also filtered and has excellent water quality, thus aiding the growth of such plants. 

But when it comes to filtered vs. distilled water for plants, filtered water is much better. Now, if you are wondering, is distilled water good for plants? It isn’t entirely true as the mineral content is low, though you should remember that it wouldn’t harm your plant, but instead, the fruit it will produce has a better flavor, away from all the chemicals that would have emerged in the taste.

How To Filter Tap Water for Plants?

You can filter water easily for plants in several easy ways, such as using home filters, distillation, RO or letting the water settle for some time. You can add activated carbon filters, such as this, can remove contaminants such as chlorine, lead, asbestos and benzene from the water.

Filter Tap Water for Plants

So, is Brita filtered water good for plants? Yes, it is. It can serve as the best water filter for indoor plants; otherwise, these pollutants could cause harm to the plants as well as the helpful microorganisms that live in the soil. 

Additionally, if you are wondering how to filter hard water for plants, know that the easiest way is to let it sit overnight so that the chlorine settles at the bottom of the bucket.

How Can Water That Is Filtered Be Used for Plants?

You can use filtered water for plants by watering in a regular form, or through a hydroponic system, and by misting it. You may simply irrigate it, or try the drip irrigation system, and lastly you can even try aquaponics.

There are numerous applications for using water filtered with outdoor or indoor plants, including the following. It is essential to remember that although filtered water may be beneficial to plants, it is equally necessary to ensure that the pH levels of the water are per the needs of the plants.

– Watering in a Regular Form

Filtered water can be used directly to water plants, either by hand or through a watering system or can. Hydrate the soil thoroughly and the foliage with water to keep them clean of dust and pests.

– Hydroponic Systems

When growing plants without using soil, the process of hydroponics is used. This is when the flowers or the vegetables that you are growing would sit in this water and grow as such, getting the right minerals from this water source.

Hydroponic Systems with Filtered Water

When you use water that has been filtered is a necessary component of hydroponic systems, replacing soil with nutrient-rich water.

– Misting Systems

To give plants the necessary humidity level for healthy growth, filtered water may be utilized in misting systems. In this case, what you should do is to spray clean water over leaves and stems to provide the required humidity and keep it clean.

– Irrigation

Water that is filtered may be combined with fertilizers for irrigation if it has been adequately treated.

Irrigation with Filtered Water

Irrigation is the simple process of watering the whole are properly and uniformly.

– Drip Irrigation

Water filtered can be utilized in irrigation systems known as drip irrigation, which supply water straight to the plant roots rather than the foliage. This will give your plant a chance to absorb the water you are providing in a smooth way, and a slow manner, where it will receive a proper amount, but in an extended amount of time. 

– Aquaponics

Water filtered can also be used in aquaponic systems, which mix hydroponics and aquaculture to grow plants and fish together in a mutually beneficial environment.
