Q: What is the decibel rating when operating? Considering it for a nursery.
A: The Shark HC455 operates quietly enough for use in a nursery, particularly in fan or purifier mode, making it an excellent choice for when a baby is asleep. These modes ensure minimal noise disruption. While the heater mode might produce slightly more sound due to the increased airflow, it still falls within a tolerable range for most households, ensuring comfort without compromising peace.
Q: What size room does this comfortably heat in terms of sq feet?
A: The Shark HC455 3-in-1 Air Purifier, Heater & Fan is designed to heat and purify rooms up to 500 square feet comfortably.
A: If the air quality percentage on your air purifier drops to 0 and stays there, it may be due to environmental factors. Activities like smoking, burning candles, running a humidifier, opening windows, and cooking can add pollutants to your air. Make sure to check your surroundings and remove anything that could be causing low air quality. If the issue persists, please call our Customer Service team at 1-855-427-5127.

Q: What happens if the product is not 3 feet from the wall?
A: Hello there, Thank you for asking such a great question! If the unit is placed too close to a wall, it can restrict airflow, which may prevent the air purifier from operating efficiently. For optimal performance, we recommend positioning it a three inches away from walls or corners to allow proper circulation. Hope this helps!
A: You’re right. The air purifier should be placed at least 3 feet (0.9 m) away from walls, large objects, or electronics to allow proper airflow. To find the Owner's Guide online, you can download it from our Shark Clean website.
Q: Is this product safe to use in a room closed off for cats?
A: Yes, the Shark 3-in-1 air purifier is safe to use in a room closed off for cats, as it uses a True HEPA filter and operates without emitting harmful substances when used as directed.
