Dirt, pollen, and any air born particles larger than the filter is designed to remove.
Are filtering air to remove dust and pollen a physical and chemical change?
Filtering air to remove dust and pollen is a physical change. This is because the process does not alter the chemical composition of the air or the dust/pollen particles. Instead, it simply separates the particles based on their physical properties.
What is the best way to remove the stains from Stargazer Lily pollen?
The best way to remove stains from Stargrazer Lily pollen is to rub the stained area with a clean area of the same fabric. This method has been known to work. Another method is to use ordinary scotch tape first to remove as much of the pollen as possible, then wash it as usual.

A cell that engulfs another cell?
A cell that engulfs another cell is known as a phagocyte. Phagocytes are a type of white blood cell that engulf and digest foreign particles, such as bacteria or dead cells, through a process called phagocytosis. This process helps the immune system to remove pathogens and cellular debris from the body.
Which system has got cilia to remove the foreign particles?
Respiratory system has got cilia all over the tracheobronchial tree. This protect the respiratory system from damage.
What is the function of globlet cells and cilia in trachea?
Goblet cells in the trachea produce mucus that helps to trap and remove foreign particles and pathogens from the airways. Cilia are hair-like structures that line the trachea and sweep the trapped particles and mucus up and out of the respiratory system toward the throat to be swallowed or expelled through coughing. Together, goblet cells and cilia help to protect the lungs from harmful substances.
Is filtering air to remove dust and pollen a physical or chemical change?
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.
What is a pool filter for?
A pool filter is there to remove particles of foreign matter from the pools water. Without a filter to remove this material it would not take long for the pools water to become cloudy and dangerous to the health of the swimmers.
What are cells that reach the surface either secrete mucus or bear cilia that sweep away mucus and trapped foreing particles?
The function of cilia is to remove foreign particles and mucus from the surface of the respiratory system. This is to prevent the blockage of airways.
What are the substances being secrete by ciliated epithelium?
Ciliated epithelium secretes mucus, which helps to trap and remove foreign particles and pathogens from the respiratory tract or reproductive system.
