Breathe Fresh Air
Air purifiers are devices that remove pollution that can cause health problems like asthma, allergies and infections from the air in a home.
These devices clean the air by using filters to remove dust and other particles that can cause breathing problems from the air. The filter to look for is a HEPA filter which captures 99.97% of the particles in the air. They use ultraviolet (UV) radiation generated by germicidal UV lamps to kill disease causing microorganisms such as germs, mold, bacteria and viruses. Such devices also use charcoal or activated carbon air filters to capture harmful chemical fumes and smoke.
Many air purifiers come with an added device called an ozone generator. An ozone generator makes ozone which is a chemical that masks many odors. Ozone can actually make respiratory problems worse because it irritates the throat and nose so it should be used sparingly.
Another process used in some air cleaners is ionization. This process gets particles out of the air by ionizing them which makes them too heavy to stay in the air. Some devices combine ionization and HEPA filters.
To be effective an air cleaning system must contain a fan. The only way such a device can clean all the air in a room is for the air to circulate throughout the room.
There are two main kinds of such devices out there, room air purifiers and whole house air filtration system. A room air purifier is a smaller device similar in size and shape to a space heater. These devices are relatively cheap and portable. The best models combine HEPA filters, germicidal UV lamps and activated carbon air filters. A few of them also add ionization and ozone generators.
Room air purifiers are often fairly cheap and can be purchased at large retailers. They require no installation but several of them maybe needed to clear the air in a home.
A whole house air filtration system is a larger version of an air purifier that is attached to a ventilation system or forced air heating system. This device cleans the air in the entire house. Whole house air filtration systems have to be connected by professional installers.
Air filtration systems or air purifiers come in all shapes. The best of them can help clean the air in house and improve your health in the process. With modern air cleaning technology nobody needs to up with polluted air indoors. |
