Indoor water features like fountains and waterfalls can greatly enhance a home or office environment. The pleasant sights and sounds of flowing water have been shown to reduce stress, lower heart rate, and blood pressure, and promote feelings of tranquility. However, without proper humidity control, indoor water features can also lead to issues like mold growth, condensation dripping, musty odors, and general discomfort.
In this comprehensive guide, I’ll discuss best practices for balancing indoor air quality when installing indoor fountains or water features. Carefully controlling humidity levels with quality dehumidifiers, paired with good ventilation and air circulation, allows you to enjoy the benefits of indoor water elements while preventing potential downsides.
Introduction to Indoor Air Quality and Humidity Control
Indoor air quality refers to the comfort and healthiness of the air inside a building. Good indoor air quality means maintaining acceptable temperature, humidity, and ventilation rates. It also involves minimizing air contaminants like dust, odors, mold, and chemicals.
Humidity is the amount of moisture or water vapor present in the air. Humidity directly impacts indoor air quality and human comfort. The ideal indoor humidity range for health and comfort is generally 30-50%. Below 30% can feel too dry, while above 50% promotes mold growth and that “damp” feeling.
Controlling indoor humidity is crucial when introducing new moisture sources like indoor fountains and waterfalls. Dehumidifiers remove excess moisture from the air to regulate humidity. Meanwhile, ventilation strategies like opening windows, running bathroom fans, and using air conditioners also modulate moisture levels.
Benefits of Indoor Water Features for Mental Health and Aesthetics
Before covering humidity control, let’s discuss the many positive effects that indoor water elements can have in homes and workplaces:
Reduced stress & improved relaxation: The sights and sounds of gently flowing water have been scientifically shown to lower heart rate and blood pressure. Water features promote calmness and serenity.
Increased air quality: Fountains and waterfalls add moisture to dry indoor air, which can improve respiratory health, skin moisture, and general well-being when maintained in moderation.
Enhanced ambiance: The tranquil sounds of a water fountain or waterfall can mask distracting noises like traffic or conversations. This improves your environment’s ambiance.
Customizable aesthetics: Indoor fountains come in limitless styles, materials, sizes, and designs to match any space’s desired look and feel.

When thoughtfully incorporated into a space, indoor water elements like fountains or waterfalls provide relaxation, beauty, and unique design aesthetics. Just be sure to control the resulting humidity levels!
Potential Downsides of Indoor Water Features: Increased Humidity and Mold Risk
While indoor fountains provide many benefits, they also introduce substantial new moisture into a space. Some potential problems resulting from unregulated humidity are:
Mold growth: Excess moisture promotes the growth of mold, which impacts air quality and human health. Mold can damage surfaces, walls, and objects in a space.
Condensation & dripping: Humid air condenses on cooler surfaces like windows and walls, leading to potential dripping, stains, and water damage.
Musty odors & scents: Stagnant water and dampness produce musty, unpleasant scents in an indoor environment.
Discomfort & allergies: Many people feel uncomfortable and stuffy in perpetually humid, clammy indoor air. Increased humidity also worsens allergies and asthma.
Bacteria & pests: Damp indoor environments allow bacteria, dust mites, cockroaches, and other pests to thrive.
Carefully controlling humidity via dehumidifiers, ventilation, and air circulation prevents these indoor air quality issues.
Function of Dehumidifiers for Regulating Indoor Humidity
Dehumidifiers are appliances specifically engineered to remove excess moisture from indoor air and regulate humidity. There are two main types:
Refrigerant dehumidifiers cool air to condense its water vapor, then collect and drain away the condensate. They’re the most common type.
Desiccant dehumidifiers use materials that absorb moisture, then heat to evaporate the moisture and exhaust it outside.
Good dehumidifiers for home or commercial use should:
Maintain optimal 40-50% relative humidity.
Offer humidistat controls for customized humidity settings.
Have sufficient moisture removal capacities for the space size.
Be Energy Star rated for efficiency.
Run quietly so they don’t disturb occupants.
Offer convenience features like timers, auto-restart, filters, and alerts.
Provide options for continuous draining via pump or gravity.
With the right dehumidifier model and settings, indoor humidity can be perfectly balanced to allow indoor water features while preventing mold, condensation, discomfort, and stuffiness.
Key Factors in Selecting Dehumidifiers for Indoor Water Feature Spaces
Choosing an appropriately sized and featured dehumidifier is critical for indoor fountain/waterfall spaces. Key factors include:
Room size – Consider room square footage and height to calculate the required pint/day moisture removal rate.
Air circulation – Rooms with high air circulation require more dehumidification power.
Outdoor humidity – Homes in humid climates need larger capacity dehumidifiers.
Water feature size – Larger water elements with more exposure release more moisture.
Occupancy – More people means more breathing/perspiration moisture.
Ventilation – Rooms with more ventilation from windows, fans, or HVAC systems need less dehumidification.
Energy efficiency – Look for Energy Star-rated units to save on electricity costs.
Humidistat – Models with adjustable humidistats maintain custom humidity levels.
Selecting the properly sized and featured dehumidifier, and pairing it with ventilation strategies, provides optimal humidity control for indoor water features.
Recommended Humidity Levels for Health and Comfort with Water Features
Here are the ideal humidity ranges to target for indoor spaces with fountains and waterfalls:
General comfort range: 40% – 50% relative humidity.
Warm/humid climates: 40% – 45% relative humidity.
Cool/dry climates: 45% – 50% relative humidity.
Lowest mold risk: 40% – 45% relative humidity.
Maintaining 40-50% relative humidity balances comfort and mold prevention in homes or offices with indoor water elements. Utilize a humidistat-enabled dehumidifier and hygrometer to monitor conditions.
Anything below 40% humidity tends to feel too dry for most people, contributing to sinus congestion, dry skin, and static electricity.
Humidity levels consistently over 50% promote mold growth and that damp, stale air feeling. Allergies and musty odors also increase.
Shoot for 40-45% humidity to get the benefits of water features while minimizing risks. The dehumidifier, ventilation, and hygrometer work together to maintain ideal conditions.
Strategic Placement of Dehumidifiers Relative to Indoor Fountains
Properly situating dehumidifiers maximizes their efficiency at controlling humidity from indoor water features. Recommended placement includes:
Near the water feature – This directly captures the released moisture.
Near known humidity problem areas – Place near windows prone to condensation or dripping.
Central to the space – Centrally located units dehumidify the whole room’s air.
Near room entrances – This captures moisture entering from other humid zones.
Away from corners – Don’t hide dehumidifiers in corners or alcoves. Allow air circulation.
Elevated if possible – Raising units off the floor enhances airflow and moisture capture.
Strategic Placement of Dehumidifiers Relative to Indoor Fountains
Take humidity readings around the room with a hygrometer to identify problem areas. Position the dehumidifier accordingly to create the maximum impact on moisture control.
Sizing Dehumidifiers Appropriately for Room and Water Feature Size
Inadequately sized dehumidifiers struggle to control humidity from large water features in spacious rooms. Follow these guidelines:
Measure room size and multiply by two for fountains – This estimates the needed pint/day capacity.
Add capacity for humid climates or poor ventilation.
Add capacity if the water feature is large, open, and actively misted.
Look for dehumidifiers matching your calculated capacity, or size up.
Supplement with additional units if needed to control humidity sufficiently.
A 2,000 ft2 room with an open evaporative fountain may need a 200-pint/day unit, for example. An undersized dehumidifier leads to humidity control issues and mold risks.
Models of Energy Efficient Dehumidifiers to Consider
Numerous companies make residential and commercial dehumidifiers that fit various needs. Some top energy-efficient models to consider include:
Frigidaire – The FFRD7033R1 70-pint dehumidifier efficiently handles large spaces.
Honeywell – The TP50WK Through-the-Wall Energy Star 50-pint dehumidifier installs neatly out of sight.

The desiccant material (rather than cool coils) absorbs and traps moisture, then expels it outside. Look into desiccant models like the Aprilaire 1830 for state-of-the-art humidity control.
Programmable Humidistats and Hygrometers for Customized Humidity Control
Today’s dehumidifiers offer advanced humidistat controls for custom humidity targeting:
Adjustable humidistats (35% to 80% RH) let you define the optimum moisture level.
Humidistats maintain this target by automatically cycling the dehumidifier on and off.
Built-in hygrometers measure and display the current humidity reading.
Some models integrate humidity sensing with smart home platforms.
Program the humidistat to your optimal RH setting between 40-50%. The dehumidifier cycles on when humidity rises above this point, shutting off once the target is reached.
Monitor conditions with a hygrometer, and adjust the humidistat as needed to remain in the ideal zone. This allows automated, customized control over humidity for indoor water features and comfort.
Signs of Excess Humidity to Watch Out For
In addition to monitoring humidity readings, be alert for these signs of excessive moisture indicating a need for increased dehumidification:
