Air Filters

Air filters are fabricated to filter and remove variety of contaminants from air, involving molds, pollens, bacteria, gases, dirt and odors. They are made up from different fabric materials like gauze, polyester and metals like stainless steel. These are mainly applicable in building ventilation systems, engines, such as internal combustion engines, gas compressors, diving air compressors, gas turbines etc.

Efficiency and Applications of Air Filters

The filter efficiency of air filters is figured out by size of filter fiber, density of fibers and velocity of the air that moves through the filter. Air filters are used in several industrial applications like :

• Domestic and Industrial Appliances : Depending upon the requirement, different types and sizes of air filters are used in domestic and industrial sector to improve the quality of air. Clean and pure air assures long life to the individual machines like air conditioners, vacuum cleaners and humidifiers.
• Automobile Industry : Air filters are widely used in several form of vehicles to promote engine hygiene. Usually, cabin air filters and combustion air filters are used in automobile sector. Their main function is to prevent separate particle of matter from entering the engine combustion chambers, proper functioning of engines and raising their life.

Types of Air Filters

• Mechanical Filters
• Gas Phase Filters
• Electronic/Electrostatic Filters
• Ozone Air Filters
• Hybrid Filters

Buying Tips For Air Filters

Air filters play a vital role in improving the air quality that we breathe inside. Before picking up any filter, you must remember some essential points :

• Warranty: Good quality air filter provides longer warranty period.
• Cost: Firstly decide your budget, this will help you to get the appropriate one.
• Size: According to your need, pick up the air filter. For single person, it is usually smaller in size and capacity and vice versa.
• Noise : Some air filters produce lot of noise, hence this may create problem.
• Power Source: It completely depends on user requirement, still user must check the power source is either AC or DC.
• Efficiency % of particles: Depending upon the requirement of user need, you select the right filtration technology as some of them are efficient in removing smaller particles while some at bigger particles.
