Air Cleaner:
An air cleaner, also known as an air purifier, is a device designed to remove pollutants and improve indoor air quality. Here are some common features found in air cleaners:

Filtration System: Air cleaners often utilize various filters to capture airborne particles such as dust, pollen, pet dander, mold spores, and other allergens. Common types of filters include pre-filters, activated carbon filters, and True HEPA filters, which can remove fine particles.

CADR (Clean Air Delivery Rate): The Clean Air Delivery Rate measures how efficiently an air cleaner can remove specific pollutants from the air. Higher CADR values indicate faster and more effective air purification.

Air Quality Sensors: Some air cleaners have built-in air quality sensors that detect the level of pollutants in the air. These sensors can automatically adjust the fan speed or other settings to optimize air purification based on real-time air quality readings.

Multiple Fan Speeds: Air cleaners often offer multiple fan speed settings to adjust the purification intensity. Lower speeds can be suitable for quieter operation during sleep, while higher speeds provide faster air cleaning.

Humidifier:
A humidifier adds moisture to the air to increase humidity levels in indoor spaces. Here are some common features found in humidifiers:

Humidification Technology: Humidifiers use different methods to add moisture to the air, such as ultrasonic technology, evaporative wicking, or steam humidification. The specific technology employed may vary depending on the model.

Humidity Control: Many humidifiers allow you to set and control the desired humidity level in the room. They may have built-in sensors to monitor and maintain the set humidity level automatically.

Water Tank Capacity: The water tank capacity determines how long the humidifier can run before needing a refill. Larger water tanks provide longer continuous operation without frequent refills.

Mist Output Control: Humidifiers may feature adjustable mist output settings, allowing you to control the amount of moisture released into the air. This feature provides flexibility to meet your specific humidity needs.

Safety Features: Some humidifiers include safety features such as automatic shut-off when the water level is low or when the desired humidity level is reached. These features help prevent damage and ensure safe operation.
