I bought a Air Purifier yesterday. Its brand name is Vicks.
Vicks® True HEPA Air Purifier
* Advance 4-stage HEPA filtration system captures airborne particles and bacteria as small as 0.3 microns, such a Bacteria, Dust, Smoke, Pet Dander
* Four speed Settings include Turbo and quiet settings
* Easy to replace drop-in filter cartridge
* Certified to filter the air in an average size room (12 x 18 feet) up to 5 times per hour
* Ionizer freshens and helps remove particles from room air
* 3 year Warranty
* Uses Kaz Replacement Carbon Pre-Filter CF1 and HEPA Replacement Filter HF130
After these two day’s use, I feel it is good for my home.
It has 4 speed fan. The quiet speed is really quiet.
WHAT ARE PORTABLE AIR CLEANERS?
Portable air cleaning devices assist in reducing indoor air pollutants.
WHAT TYPES ARE AVAILABLE?
HEPA FILTERS are the most efficient mechanical filters for removing small particles which can be breathed deep into the lungs. The highest efficiency air cleaners, widely available today, remove 0.3 micron (1 micron = 1 millionth of a meter) sized particles at a minimum of 99.97% efficiency.
ELECTRONIC AIR CLEANERS (NEGATIVE IONIZERS), in their simplest form, include negative ion generators that charge airborne particles so they become attracted to and settle on room surfaces. Activity within a room, however, may stir up and release the settled particles back into the air. More effective units called electrostatic precipitators electrically charge airborne particles and then trap them on oppositely charged metal plates. These plates must be cleaned regularly for proper performance.
GAS PHASE FILTERS are often attached to air cleaning devices to filter specific gases, vapors and odors.
PERSONAL AIR PURIFIERS use corona discharge technology to purify air within your personal breathing space. They are worn around the neck and use a combination of technologies to eliminate bacteria, airborne dust, and contaminants. Most run on battery for up to 50 hours.
HOW DO I CHOOSE?
PORTABLE AIR CLEANER
Generally, portable units are used when air cleaning is desired in a room. You should match up the area of your room to the specified cleaning ability of the particular unit.
The efficiency of an air cleaner is measured in terms of the particle size that the device can capture. In most cases, very small particles are the ones that penetrate deep into the lungs, causing health problems. Look for mechanical filters such as HEPA filters and electronic air cleaners that can effectively trap large and small particles.
CLEAN AIR DELIVERY RATE
The overall effectiveness of an air cleaning device depends on the efficiency of the unit and on the amount of air drawn through it. Although no industry-wide set of performance standards exists to help consumers compare units, the Association of Home Appliance Manufacturers (AHAM) has developed a standard for portable air cleaners called the Clean Air Delivery Rate (CADR). The CADR expresses the number of cubic feet of clean air a unit delivers each minute.
Some air cleaners (called ozone generators) use an electrical charge to generate ozone. Although ozone (also referred to as trivalent oxygen or saturated oxygen) is a necessary part of the upper atmosphere (10-30 miles above us), in the part of the atmosphere we breathe, ozone is a potent lung irritant. It can have damaging health effects, especially for persons with asthma and other lung diseases, children and the elderly. It is produced directly by ozone generators and indirectly by ion generators and some other electronic air cleaners. The FDA has set a limit of 0.05 parts per million of ozone in indoor air. Ask whether any electronic air cleaner you are considering buying has been tested for ozone production. The American Lung Association suggests that ozone generators not be used.
