Air purifiers can remove contaminants from an indoor environment and give you cleaner air, fresher air to breathe. Whether for your home, office, or car, there are air purifiers that will suit your needs. Many are light and portable, making them convenient to have.What is an air purifier, and what does it do?
An air purifier is an instrument that is designed to filter out dust, pollen, mold spores, dust mites, pet dander, smoke particles, allergens, and bacterium from the air in a specific room or area. These kinds of pollutants are harmful to people, particularly those who suffer from allergies or asthma. Air purifiers can be used in many different types of environments and come in a variety of shapes and sizes, but they all serve a similar purpose and that is to improve the air quality in your home or work space.Are there different kinds of air purifiers?
Although all air purifiers remove contaminants and pollutants from the air, there are several different ways an air purifier can do this. These purifying designs can include the following:
- Filter-based: This design works by capturing molecules in a filter when air is forced through the device. A true High-Efficiency Particulate Arrestance (HEPA) filter can remove 99% of small pollutants. HEPA filters are the most common type of air purifier found in households. They don't generate any harmful byproducts and can be added to HVAC systems and filtration systems or purchased as stand-alone products.
- Thermodynamic sterilization: This design uses heated sterilization technology to incinerate up to 99% of microbiological particles that pass through the purifier.
- Ultraviolet germicidal irradiation: This design sterilizes air by forcing it to travel through ultraviolet lamps. The UV light kills harmful bacteria by damaging the cells’ DNA beyond repair.
- Ionization: Ionic purifiers create electrically charged ions that attach to harmful molecules. The particles are caught on a collection plate and filtered out. Ionic air purifiers can be mounted in homes or industrial settings and are also sometimes called electrostatic precipitators.
- Ozone generators: Ozone generators are intended for empty spaces and not filtration systems as it is not healthy to breathe the gas. They are typically used for commercial settings and use a gas to oxidize and filter other chemicals and allergens.
There are also many different sizes of air purifiers to choose from. They range from commercial-sized purifiers for large work spaces to personal air purifiers for an individual room in your home. They also can be manufactured as large units that can be attached to HVAC systems. You can even purchase small, light, HEPA filters that are designed for travel.
