Why is my Insignia Air Cleaner so loud or have poor air flow?
Your Insignia Air Cleaner might have poor air flow or be loud due to several reasons. Ensure your air purifier is on a flat surface and that nothing is blocking the air inlet and filtered air cover. Position your air purifier at least 1 foot (.3 meters) away from walls or large objects. Check the condition of the filter and replace it if it’s dirty. Also, ensure you remove the plastic bag from the filter and that the filter is seated correctly.
