These types of air purifiers don't heat up or have dangerous parts to worry about when left unattended. Keeping the air purifier on all day will ensure that the air in your home is constantly being filtered and purified, so you can breathe comfortably without suffering from allergies such as cough, sinusitis, eye redness, headache, and itching. However, it is important to remember to clean the filters about once a month.
Filters trap large amounts of dust and allergens, which can be harmful to sensitive groups if not cleaned constantly.

Smart Air is a social enterprise that creates simple and sensible air purifiers and provides free education to protect people's health from the effects of air pollution. The right type and size of air purifier can significantly reduce the operating time of the air cleaner.
This is usually not a problem with a decent air purifier because the air moves directly to the filter. Therefore, running the air purifier at all times is the best way to ensure that your family breathes clean indoor air that is constantly cleaned of new pollutants and other harmful particles entering your home.Leaving an air purifier day after day is the best way to ensure the highest possible level of air quality. Every little effort counts. If you prefer fresh night air to enter through the window at night, your air purifier won't be as effective.
