What Is Dehumidifier Water

Dehumidifier water is the liquid that dehumidifiers extract from the air. This process involves pulling moisture from humid air. The result is cleaner, drier indoor air and collected water.

This water is often considered “gray water.” It is not suitable for drinking but may be useful for other purposes. Understanding its composition helps in finding safe uses.

Common Uses of Dehumidifier Water In Households

Using dehumidifier water for houseplants is particularly beneficial. It helps reduce waste and conserve fresh water. Plus, it provides a steady supply for plant care.

Here is a quick comparison of common uses:

Chemical Composition of Dehumidifier Water

Understanding the chemical composition of dehumidifier water helps you decide if it’s good for houseplants. This water can be beneficial, but its composition matters.

Mineral Content

Dehumidifier water often has a low mineral content. This makes it similar to distilled water. Houseplants can thrive on low-mineral water.

Using a filter helps improve the water’s purity. Filtered water is safer for plants.

Why People are Considering Dehumidifier Water for Plants

Many houseplant enthusiasts, myself included, have started wondering if the water collected by dehumidifiers could serve as a sustainable and free alternative to regular tap water. In homes where dehumidifiers run constantly to manage indoor humidity, the water they collect is often discarded. This has sparked interest in whether that water could instead be used to benefit indoor plants.

For environmentally conscious plant owners, repurposing dehumidifier water aligns with eco-friendly living. It feels wasteful to simply pour away gallons of water, especially when indoor plants are in constant need of hydration. However, the question remains—can dehumidifier water truly replace traditional watering methods for our green friends?

Is Dehumidifier Water Safe for Houseplants?

Before you start watering your plants with dehumidifier water, it’s crucial to understand its composition and whether it’s safe for houseplants.

The Composition of Dehumidifier Water

Dehumidifier water is often referred to as “gray water.” It’s technically distilled since it’s formed by condensing moisture from the air, leaving behind minerals and other impurities. This process makes dehumidifier water relatively pure. However, it’s important to note that the water may also carry contaminants like dust, mold spores, or bacteria from the surrounding environment. The condition of the dehumidifier itself plays a role in this; a poorly maintained device can harbor mold or bacteria, which can end up in the water.

Potential Concerns and Risks

One concern is that while dehumidifier water lacks the chemicals commonly found in tap water (like chlorine and fluoride), it might introduce other impurities. Depending on how well-maintained your dehumidifier is, the water may contain dust, dirt, or traces of mold, all of which could affect plant health. Some experts recommend that if you have sensitive plants, like orchids or ferns, you should be cautious when using this water. As Marie Jones, a botanist from GreenEarth Gardening, puts it:
“While dehumidifier water can be a sustainable option, always ensure it’s clean and free from contaminants to avoid risking your plant’s health.”

I decided to test this theory on my spider plants by using water from my Frigidaire 70-Pint Dehumidifier. Over the course of a few weeks, I didn’t notice any visible negative effects. However, I made sure to clean the dehumidifier filter and reservoir frequently to reduce any risk of contamination.

Benefits of Using Dehumidifier Water for Houseplants

So, why should you consider using dehumidifier water for your houseplants? Let’s explore some of the key benefits that make it a popular choice among eco-conscious plant parents.

Eco-friendly Solution

One of the most appealing benefits of using dehumidifier water is its contribution to reducing water waste. Instead of letting this resource go down the drain, you’re reusing it to nourish your plants. This aligns with a sustainable approach to home gardening, where you minimize waste and make use of what’s available.

Cost-Effective

Watering houseplants can significantly add to your water bill, especially if you have a large indoor garden. By using dehumidifier water, you reduce your reliance on tap water and save money. This is especially beneficial in humid climates where dehumidifiers run frequently, meaning you’re collecting ample water for reuse.

Neutral pH Levels

Dehumidifier water tends to have a neutral pH, which is often ideal for plants. Many houseplants, like ferns and African violets, thrive in water that doesn’t contain the high levels of minerals found in hard tap water. The lack of chemicals such as chlorine and fluoride makes dehumidifier water a softer option, which can be beneficial for plants that are sensitive to chemical additives.

My LEVOIT Smart Dehumidifier produces gallons of water each week, and I’ve used it for my pothos and peace lilies. I’ve noticed the plants are healthier, and there’s no longer any mineral buildup on the soil or pots, something I previously encountered with tap water.

Potential Risks

Using dehumidifier water for houseplants has its potential risks. Though it seems convenient, this water might not always be safe for your plants. Let’s explore the possible dangers.

Contaminants In Water

Dehumidifier water can contain various contaminants. These include dust, mold spores, and bacteria. The water collects from the air, which is not always clean.

Here is a table showing common contaminants:

These contaminants can be harmful to houseplants. Mold spores and bacteria can lead to root rot and other issues.

Impact On Plant Health

Using dehumidifier water can have a negative impact on plant health. The impurities in the water can affect the soil’s quality.

Some plants are sensitive to poor water quality. Here are some effects:

• Leaf discoloration
• Stunted growth

Plants may struggle to absorb nutrients. This can make them weak and more prone to diseases.

It’s crucial to monitor your plants closely. If you notice any signs of distress, stop using dehumidifier water immediately.

How to Use Dehumidifier Water with Indoor Plants

Using dehumidifier water with houseplants requires a bit of care. Here are the best practices to ensure your plants thrive with this new watering method.

Cleaning and Maintaining the Dehumidifier

First and foremost, your dehumidifier needs regular cleaning. The water collected can become contaminated if the machine isn’t well-maintained. Dust, mold, and bacteria can accumulate inside the dehumidifier, and you don’t want those particles in your plant water. Cleaning the water tank, coils, and filters on a weekly basis can prevent this.

Proper Storage of Dehumidifier Water

If you’re not planning to use the water immediately, be sure to store it properly. Leaving water to stagnate in a bucket or tank can lead to bacterial growth. Use a sealed, clean container and try to use the water within a few days. Always inspect the water before using it; if it smells odd or looks cloudy, discard it.

Best Practices for Watering

It’s a good idea to introduce dehumidifier water gradually. Start by mixing it with regular tap water and monitor how your plants respond. This way, you can assess any potential negative effects before fully switching to dehumidifier water. Also, remember that different plants have different water needs—what works for your ferns might not be ideal for your succulents.

For my fiddle leaf fig, I’ve been alternating between dehumidifier water and rainwater. Using my hOmeLabs 50-Pint Dehumidifier, I’ve found that this method works well without overwhelming the plant’s soil with a sudden change in water composition.

Should You Filter Dehumidifier Water?

If you’re still uncertain about the cleanliness of dehumidifier water, you might want to consider filtering it before use.

Using Carbon or Reverse Osmosis Filters

A simple carbon filter or reverse osmosis system can further purify dehumidifier water by removing any remaining dust, mold spores, or bacteria. This step is particularly useful if you live in a high-pollution area or if you’re concerned about your dehumidifier’s cleanliness.

Pros and Cons of Filtering

While filtering adds an extra layer of security, it can also be time-consuming and costly. For most hardy houseplants, filtered water might be unnecessary, but for delicate plants, it’s worth the effort to ensure the water is as pure as possible.

I began filtering dehumidifier water through my Brita pitcher filter before using it on my more sensitive plants like air plants and ferns. Since implementing this, I’ve noticed an improvement in their overall health, particularly in avoiding fungal issues.

Types of Houseplants That Thrive with Dehumidifier Water

Not all plants respond the same way to different types of water. Let’s explore which houseplants might benefit the most from dehumidifier water.

Plants That Prefer Distilled or Low-Mineral Water
