Everything You Need to Know Before Purchasing the QDH Humidifier

The QDH Humidifier has become one of the most popular humidifiers on the market, beloved for its efficiency, versatility and smart features. But with so many models and options to choose from, it can be tricky to figure out which QDH humidifier is right for your needs and budget. This comprehensive buying guide will walk you through everything you need to consider before purchasing a QDH humidifier, from understanding the different types available to key factors like humidistat settings, tank capacity, coverage area and more.

How Does the QDH Humidifier Work?

All QDH humidifiers work by dispersing a cool or warm water mist into the air to increase humidity levels. The mist is generated by either an ultrasonic vibrating diaphragm that vibrates at a high frequency to create microscopic water droplets, or by a central wick filter that absorbs and evaporates water. The added moisture in the air provides relief from dryness, alleviates respiratory problems, and helps maintain optimal humidity levels between 30-50%.

The ultrasonic models use high-frequency sound vibrations to generate a cool mist, and tend to be quieter. The evaporative or wick filter models draw water up into an absorbent wick filter to evaporate it into the air as a warm mist. Filter types include natural materials like ceramic and wicks.

Types of QDH Humidifiers

QDH offers both cool and warm mist humidifier models to suit different needs:

• Cool Mist Humidifiers: These produce a visible, odorless cool mist using ultrasonic technology. They are ideal for warm climates and families with children, since the mist doesn’t heat the room or pose burn risks.
• Warm Mist Humidifiers: Warm mist models use evaporative wick filters to produce a visible warm steam vapor. They efficiently raise air humidity and are well-suited for cold climates when you want the comfort of moisture without a chill.
• Humidifier-Air Purifier Combos: QDH’s 2-in-1 models combine humidifying with air purification and aroma diffusing options in one unit. They filter out airborne allergens and pollutants for cleaner air.
• Top Fill Humidifiers: QDH’s latest top fill humidifiers allow you to conveniently fill the tank from the top rather than having to flip the unit over each time. This makes refilling a breeze.
• Smart Humidifiers: QDH’s smart humidifiers can connect to your smartphone via WiFi and the Q Home app for remote monitoring, scheduling, voice control and custom settings.

What is the Water Tank Capacity?

QDH humidifiers come in tank capacities ranging from 1 gallon to 1.6 gallons. The larger the tank capacity, the less frequent you’ll have to refill it. A good standard tank size is 1.5 gallons, which can provide continuous mist for 24-36 hours on low settings. Larger rooms and high mist output will deplete tanks faster. If you don’t want frequent refills, opt for 1.6 gallon or multi-room models.

Is the QDH Humidifier Suitable for Large Rooms?

Many QDH models are designed for large rooms up to 753 square feet. The higher the mist output rating measured in milliliters per hour (ml/hr), the larger room it can accommodate. Look for mist output over 300 ml/hr and multiple mist settings for sufficient humidity control in spacious areas. Some industrial QDH humidifiers can cover rooms up to 1,215 square feet.

Does the QDH Humidifier Have an Auto Shut-Off Feature?

Yes, most QDH humidifiers have an auto shut-off feature as a safety precaution. Once the tank runs out of water, the unit will automatically power off to prevent damage from overheating. Some models also have sensors that detect abnormal conditions to shut off operation before hazards occur. This provides peace of mind and protects your investment.

Where Can I Buy the QDH Humidifier?

You can purchase QDH humidifiers from major online retailers like Amazon, Walmart and eBay. QDH also sells directly from their website with regular coupon codes and discounts. Brick-and-mortar stores like Bed Bath & Beyond, Target and Costco may carry select models in-store and online. Shopping directly from QDH.com gives you the full range of models plus bundle deals.

How Do I Clean and Maintain the QDH Humidifier?

To keep your QDH humidifier operating efficiently, follow these cleaning tips:

• Daily: Empty the tank, rinse thoroughly, wipe exterior with a soft cloth and refill with fresh cool water.
• Weekly: Disinfect interior tank with a dilute bleach solution. Rinse thoroughly afterward.
• Monthly: Deep clean the tank and base with hot soapy water. Remove scale buildup with vinegar. Replace filters.

Refer to manual for comprehensive cleaning details. Proper care prolongs performance and prevents bacteria or mold growth.

Is the QDH Humidifier Quiet Enough for a Bedroom?

QDH ultrasonic cool mist humidifiers operate at less than 30 dB on low settings – about the same volume as quiet conversation. This makes them very suitable for bedrooms. The evaporative warm mist models produce some fan noise around 35-50 dB. If you prefer near silent operation, look for the ultra quiet night mode on select models.

Does the QDH Humidifier Come with a Filter?

Most QDH humidifiers come with either a reusable pre-filter, wick filter, or built-in replaceable filter cartridge:

• Reusable foam pre-filters trap minerals and impurities in the water to keep mist pure. Rinse regularly to refresh.
• Wick filters in warm mist models need occasional replacement when worn.
• Cartridge filters need replacing every 1-2 months to sanitize mist.

Filters protect the humidifier interior, clean the mist, and remove bad odors for healthier air.

How Long Can the QDH Humidifier Run on a Full Tank?

Depending on the mist output setting, a 1.5 gallon QDH humidifier will run between 24-36 hours on a full tank before needing a refill. At lower humidity settings, it can operate even longer up to 60 hours. The larger 1.6 gallon models may run for up to 50 hours per fill. Just monitor the tank levels and refill once empty.

Is the QDH Humidifier Energy Efficient?

QDH humidifiers are designed for energy-efficient operation. Features like:

• Auto shut-off when tank is empty
• Sleep and eco modes
• Adjustable humidistat
• Timer settings

All help conserve energy by allowing customized runtimes. The warm mist models tend to use a bit more energy. But selecting cool mist and lower settings saves on your electricity bill. QDH humidifiers cost pennies per day to run.

Key Considerations When Buying a QDH Humidifier

Keep these important factors in mind when choosing your QDH humidifier model:

Humidistat Settings

Look for units with adjustable humidistats that allow you to dial in your desired moisture level from 30-80% RH. Humidistats automatically regulate mist output to maintain set humidity so you don’t have to constantly monitor conditions. This prevents over-humidifying and saves energy.

Tank Capacity

Choose a 1.5-1.6 gallon tank capacity to avoid frequent refills, unless you want a small personal unit. Larger tanks run 20-40 hours per fill. But they are bulkier. You can also opt for top fill designs for easier refilling.

Room Coverage

Confirm the square footage the QDH humidifier can handle matches the size of your space. Cool mist outputs starting around 300 ml/hr cover up to 750 square feet for whole home humidity.

Runtime Per Tank

At lower settings, 1.5 gallon models run for 24-36 hours on a full tank for all day use before refilling. Larger tanks extend runtimes up to 50 hours per fill.

Filter Types

Evaluate whether replaceable filter cartridges or reusable wick/pre-filters best suit your needs and budget long-term.

Noise Level

Ultrasonic cool mist models are near silent at under 30 dB for bedroom use. Evaporative units have some fan noise. Look for nighttime modes and low settings if using in quiet rooms.

Safety Features

Look for auto shut-off when tank is empty along with tip-over switches and overheat protection for safe unattended operation. Cool mist is safer if you have kids.

Special Features

Consider convenient top fill tanks, aromatherapy, air purification, and smart app connectivity for advanced humidifier benefits. Remote controls also provide easy control.

Cost

QDH humidifiers range from $50 for 1 gallon models to $250 for large smart humidifiers. Determine how much you want to invest based on features, runtime, and tank capacity.

By carefully comparing the different options using these criteria, you can zero in on the best QDH humidifier for your budget and needs. Choosing the right model will help you efficiently and safely control humidity levels.
