Heating, Cooling & Air Quality

They do opposite jobs:

• A humidifier adds moisture to dry air, which is common in winter when heating systems run.
• A dehumidifier removes excess moisture from damp spaces like basements and bathrooms, where humidity can lead to musty odors.

Many homes use a humidifier in winter and a dehumidifier in humid summer months. Shop both in Humidifiers & Dehumidifiers.

Indoor humidity between about 30% and 50% is generally recommended for comfort. Below that, air can feel dry and staticky. Above it, spaces can feel muggy and become more prone to mold. A humidifier with a built-in sensor, like the Smart Sensing Digital Ultrasonic Humidifier, can adjust its output to help keep humidity in range.

An ultrasonic humidifier uses high-frequency vibrations to turn water into a fine, cool mist. That makes it very quiet, which is ideal for bedrooms and nurseries. Clean it regularly and follow the manufacturer’s instructions, and use distilled water if the manual recommends it to reduce white dust. Shop ultrasonic options in Humidifiers & Dehumidifiers.

To use a space heater safely, follow these basics:

• Keep it at least 3 feet away from anything that can burn, like curtains, bedding, and furniture.
• Plug it directly into a wall outlet, not an extension cord.
• Never leave it running unattended or while you sleep.
• Choose a model with tip-over protection and overheat shut-off.

Many electric fireplaces include a built-in heater, while others only create the look of flames for ambiance. Check the product details to see if a model provides heat and how large a space it’s designed for. Electric fireplaces need no chimney, gas line, or venting, so they can go almost anywhere with an outlet. Browse Indoor Fireplaces.
