A fan and one or more filters are components of air purifiers. Air is drawn in by the fan (or occasionally a set of internal fans), and is then passed via the internal filters. Clean air is sent back into the space after being captured by these filters, which also scatter germs, dust, and pollen. Indoor air circulation is kept in good condition by this filtration procedure.

Air Purifier Types
Although HEPA (High-Efficiency Particulate Air) filters are included in the majority of air purifiers, some models also have UV or activated carbon filters. A few highly developed air purifiers combine two or three different kinds of filters. This section covers the many kinds of air purifiers and their functions:
HEPA Filters: Mold spores and other contaminants as small as 0.3 microns can be captured by air purifiers that use HEPA filters. Human eyes are not even able to detect these little particles. At least 50 to 60 microns in size are the smallest particles that are visible to us.
Activated Carbon: Odors are efficiently captured by activated carbon filters used in air purifiers. But unlike HEPA filters, activated carbon filters are unable to catch germs and viruses.
Electrostatic Precipitators: High voltage electrical energy is used by air purifiers with electrostatic precipitators to charge the particles that pass through the filters. On the electrostatic plates, the dead germs continue to accumulate. These electrostatic plates need to be changed often in order to keep the filter operating as efficiently as possible, which raises the expense of maintenance. Oxygen is another reactive gas that electrostatic precipitators emit that may harm your lungs.
Ultraviolet Light Air Purifiers: These air purifiers work by destroying airborne bacteria with UV light. Make sure the UV light air purifier you’re purchasing doesn’t emit ozone before making the purchase.
Ozone Generators: Odors are absorbed by air purifiers that have ozone generators. They are frequently found in hotels since the significant amounts of ozone these air purifiers generate render the room unfit for occupancy for the next 24 hours. Chest discomfort, coughing, and shortness of breath can all result from exposure to ozone, even at low levels. Extended exposure exacerbates respiratory issues and destroys the lungs.
Portability: A portable air purifier’s design makes it easy to move and utilize in a variety of settings. Compared to other kinds of air purifiers, it usually has a smaller size and weighs less, making it easier to travel and more flexible. A variety of efficient filtration methods and features are still available in many small air purifiers, even if some may have fewer sophisticated features than bigger versions.
FAQ
Can coronavirus be avoided using air purifiers?
No, there isn’t any proof that air purifiers can get rid of the coronavirus. Particles as thin as 0.3 microns are often captured by HEPA filters, but the coronavirus is much smaller. There are studies that indicate that UV-lit air purifiers may eliminate tiny germs, but none that demonstrate their ability to eradicate the new coronavirus.
Do air purifiers improve your quality of sleep?
Yes, by clearing your home of allergens, air purifiers improve your quality of sleep. Some people may have signs of disturbed sleep in response to allergens. Having trouble breathing, sneezing a lot, or coughing often are examples of allergic responses that might interfere with your sleep. Air purifiers work by capturing contaminants in the air, which reduces the likelihood of allergies. An atmosphere that is fresh and clean helps you sleep better. Your mood and cognitive abilities are also enhanced by getting a good night’s sleep.
How much time does a room need to be cleaned by an air purifier?
The majority of air purifiers clear a room in 30 to 2 hours. The length of time is determined by the room’s dimensions and the air purifier’s ACH rating. The amount of times per hour that the total volume of air in your room is filtered is indicated by the ACH rating. The best air purifiers filter four or five times in an hour. Whenever you are in the room, it is advisable to leave the air purifier running.
What location is best for my air purifier?
You may put the air purifier in your bedroom or living area. The goal is to breathe clean air in the areas where you spend the majority of your time. The air purifiers are portable, so if necessary, you can transfer them from room to room.
Do air purifiers pose a health risk?
Not every air purifier is unhealthy. Certain air purifiers that release ozone can be dangerous. They produce coughing, chest discomfort, and dyspnea. Increased ozone exposure can harm your respiratory system. Generally speaking, using air purifiers with HEPA and activated carbon filters is safe.
Are air purifiers effective?
Indeed, a significant portion of the airborne allergens and irritants that pass through the filters of air purifiers are captured. They improve the interior air quality in the process. A plentiful quantity of pure, fresh air is provided to you. One of the several actions you can do to lessen indoor air pollution is to use air purifiers. Other measures to keep your interior space clean include cleaning your floors, carpets, and upholstery and permitting cross ventilation.
