There are at least fifteen major brands promoting air purifiers. Below you will find condensed air purifier reviews for four of the most popular brands:

Oreck Air Purifiers

The Oreck Super Air 8 Air Purifier uses four different technologies to clear your air. The pre-filter catches large particles such as dust and pollen. The charcoal filter captures some of the smaller particles and chemicals that irritate the eyes and throat. Then the electrostatic precipitator electronically charges small particles with a negative ion, and immediately a collector plate magnetically grips the charged particles. Simultaneously, the Oreck air purifier generates negative ions and sends them out into the air, causing pollutants to drop right out of the air.

Ionic Breeze Air Purifiers

The Sharper Image Ionic Breeze GP uses a combination of electrostatic precipitator, negative ion generator, and an ultraviolet light. The ultraviolet light is a new improvement to the unit, which works to kill bacteria and viruses. The Ionic Breeze air purifier generates high amounts of harmful ozone, so make sure you place the unit at least two to ten feet away from your bed and furniture.

HEPA that stands for High Efficiency Particulate Arrestor is a type of air filter used for cleaning the air specially in equipments like vacuum cleaners. These air-purifiers filter the particles in the airborne environment down to 0.3 microns in size and at a speed-rate efficiency of 99.97%. The HEPA air-purifiers with their high-efficiency level have trimmed the usage of age-old air-cleaners. They not only purify the air but also remove even the smallest microns of allergens like dust, smoke, pollen, animal danders, bacteria and other industrial/chemicals effectively from the atmosphere.

Working of the HEPA air purifiers

The HEPA air cleaners work by filtering the allergens in the air through a HEPA air-filter that traps the particles allowing the clean air to return to the atmosphere. The larger number of times that the air passes through the HEPA filters, the better and cleaner becomes the quality of the air. So till date the HEPA purifiers have proved to be the most tried-and-true air-cleaning instruments. The best part about HEPA air-purifiers is that they never emit any byproducts or secondary pollutants such as ozone and ions.

The main instrument that makes the HEPA purifiers work so efficiently is the fan inside the filter. The fans aid in the trapping of large particles in the fold of the filters while the small particles and chemicals gets attached to the charcoal in the filter.

Some of the HEPA air-purifiers have fans that have a straight design where the air is drawn in from the back of the purifier and blown out through the front of the purifier. These units clean the air specifically and prove to be truly effective for bedrooms and sitting rooms. Others have unidirectional fans that pull the air from all sides of the machine and blow the filtered air out in all directions. These types of HEPA air-purifier are needed for purifying the air in the entire home. So whether it’s the larger particles or the smaller ones, the HEPA air-purifiers can clean the atmosphere completely.

Are you suffering from polluted or allergen-rich air in your home and office? You should take some steps to prevent such air from flowing in your home and instead let fresh air fill up the atmosphere. You can use air-purifiers that are basically designed to reduce the dust build-up within the home and office environment. The air-purifiers are electronic in nature and use a basic filtering system to draw-in bad air, clean it and re-circulate fresh air outside.

Air purifiers are specifically designed to eliminate pollutants such as pollen and other airborne irritants from the environment. The working in air-purifiers is quite simple. The air in the room is drawn inside to the bottom of the cleaner and then is pushed forward through an aluminum mesh filter. It is this filter where the pollutants are captured before the air moves on to the next phase for getting cleaned.

Factors to be considered while purchasing air-purifiers

When you want to purchase an air-purifier, you should take into account several factors. The first is the size of the machine. If the area where purification should take place is large, then a machine can filter the air of the entire house. The purifier should then be lifted in the wall or in the ceiling for better results. The second factor is noise level. Some of the air-purifiers produce a lot of noise so if you want to maintain peace in your home, you should get a noiseless air-purifier. The third factor to be considered is air re-circulation rate, a quality that changes the room ambience at least for 3 times in an hour. The fourth factor is choosing the purifier that can be cleaned by hand, washed or vacuumed.

With the increase in pollution levels in the country, the customer’s demands for air-purifiers have been increasing at an alarming rate. The air-purifiers assist in purifying the contaminated air in your home and office thereby freeing the air from unnecessary pollutants. A close research on environmental sciences suggests that the air outside home is far more pure than the air inside the home. So the air-purifiers are known for converting the contaminated air to clean air and provide protection against pollutants.

The modern air purifiers have gained such popularity in the consumer market that they have well mutated the use of air-cleaners. While the air-cleaners clean the air, the air-purifiers absorb dust, pollen, viruses, molds, tobacco smokes, dust mites and other industrial/household chemicals, thereby purifying the air completely. The people who get mostly benefited from air-purifiers are those that suffers from constant allergies, asthma and other respiratory ailments.

Today the air purifiers come in a package containing top-class elements that have increased the usage of air-purifiers to a great extent. The air-purifiers contain HEPA [High Efficiency Particulate Air] filters, ion generators, ozone generators, electrostatic filters, ultraviolet light and other methods that help the air-purifiers to get rid off both large and miniscule particles.

Air purifiers come in various shapes, sizes, and types. Out of these various types of air-purifiers, while some of the air-purifiers draw in air via a fan, cleaning the air and re-releasing it, most of the other air-purifiers work by actually spreading the purified air in the entire room.

Following are the various types of air-purifiers available in the market:

1) Room air-purifiers – room air purifiers have replaced the tabletop units in the 1990s as the leading brand of air-purifiers. These are portable, lightweight and flexible in use. So you can install them almost anywhere in your room.

2) Ion generators – these air-purifiers work by generating charged ions into the atmosphere. The ions get attached to the dirt and chemical-contents in the atmosphere causing them to get attracted to the floors of the houses and get deposited in the grounds. You can then wipe them, mop them or vacuum them away from floors.
