The devastation of the world is becoming a problem in this generation thereby efforts at providing the best solution are prioritized; this devastation brought alarming effects such as flooding, pollution and most especially global warming. Scientists work hard to develop and improve a technology that specifically cleans the basic need of every people-air. Pollutants and contaminants present in the air can even penetrate in our houses thereby a reliable appliance in the form of air purifier is needed. Before purchasing specific air purifiers, you should consider factors such as the room coverage, the price, filtration technologies and product reviews.

Air purifiers can be classified according to room coverage; you can choose between whole house air cleaning system and portable air cleaners for your household air problems. Whole house air cleaning system protects your entire space but with it comes a price. The portable air cleaners on the other hand only cover 150 square feet to 2000 square feet of the room depending on the model; these portable air cleaners are appealing because it is cheap and transferable through out your house. The next thing that you should keep in mind after determining the specific air purifier best for your house is the filtration technologies best for your household. There are four basic air filters  such as of HEPA (High Efficiency Particulate Arrestor) filters, Carbon filters, Germicidal UV lamps and most especially Electrostatic air purifier (also called ionizers) that can also be impregnated on any HVAC (Heating, Ventilation and Air Conditioning) units.

HEPA filters are one of the best because it effectively delivers 99% of clean air. The carbon filters on the other hand are effective at adsorbing gaseous substances and odors such as smoke, cooking smells, smog and other VOC (Volatile Organic Compounds). The germicidal UV lamps are best at eliminating present micro-organisms like bacteria, viruses and molds. The last type is the electrostatic air purifier which is best at capturing dusts, pollens, dander and other airborne contaminants; ionizers carefully emit negative ions in the air which effectively bond with positive ions like contaminants and as a result, bonded particles settle in the surface. Bonded particles can easily be cleaned via vacuum cleaners. Furthermore ionizers are cost effective because it only requires frequent cleaning unlike other filters that need frequent replacements.

Manufacturers and products like IQair Compact, Blueair, Allerair and Austin air are the best in air cleaning business.
