Why do you need an air purifier?
The air purifier contains one or more filters and fans. A fan (or possibly an internal fan system) draws in air that passes through an internal filter. These filters trap contaminants such as dust, pollen, and bacteria and return clean air to the room. This filtration process maintains healthy air circulation in the room.
Types of air purifiers
Most air purifiers include HEPA (high-efficiency particulate air) filters, but some air purifiers include other types of filters, such as activated carbon and ultraviolet light. Certain technologically advanced air purifiers include a combination of two or three types of filters. This section describes different types of air purifiers and their features.
HEPA Filter – An air purifier with a HEPA filter can capture contaminants as small as 0.3 microns. These tiny particles are invisible to the human eye. The smallest particles we can see are at least 50 or 60 microns in size.
Activated Carbon: An activated carbon filter air purifier effectively traps odors. It cannot capture viruses and bacteria like HEPA filters.
Electrostatic Precipitator – An electrostatic precipitator air cleaner uses high-voltage electrical energy to charge particles as they pass through a filter. Dead pathogens continue to accumulate on the electrostatic plates. To maintain filter efficiency, these electrostatic plates must be replaced periodically, increasing maintenance costs. Electrostatic precipitators also release ozone, a reactive gas that can damage the lungs.
Ultraviolet Air Purifiers – These air purifiers use ultraviolet light to kill bacteria floating in the air. Some UV air purifiers emit ozone, so check before you buy this type of purifier.
Ozone generator: An air purifier equipped with an ozone generator absorbs odors. The high levels of ozone emitted by these air purifiers make them unsuitable for use in rooms for the next 24 hours and are therefore commonly used in hotels. Exposure to low levels of ozone can cause chest pain, coughing, and shortness of breath. Prolonged exposure damages the lungs and exacerbates respiratory problems.
The air purifier market is full of options, but in the end, the customer must first determine what type of protection they are looking for. Whether looking to alleviate allergies or filter smoke from a room, customers need to choose the best air purification solution like levoit vista-200 for their illness and other air pollutant protection needs. .. We hope this page has given you a solid and useful introduction to air purifiers and what they can do. Every day, many people and the medical community seem to be becoming more aware of the need for clean air.
