Different Types of Air Filters Explained


If you want better indoor air quality, then you require an excellent air purifier. Air purifiers reduce the airborne pollutants which aggravate asthma and allergies. As dirty, polluted air flows through the air conditioner, clean, fresh air flows into your home. The type of air filter in an air purifier decides how the air purifier operates – and how well it works.

HEPA Filters

HEPA air filters establish the standard for air cleaners now. From the 1940s, the U.S. Atomic Energy Commission developed HEPA (High Energy Particulate Air) filters in an effort to filter radioactive contaminants. To be classified as a HEPA filter, then it must catch a minimum of 99.97% of pollutants at 0.3 microns.

HEPA filtration captures particles 25-50 times smaller than the eye can see. The ultra-fine fibers in HEPA filters capture microscopic particles through a mix of diffusion, interception, and inertial impaction. With bigger particles, diffusion takes place whenever the random movement of the particles causes them to collide with fibers. Interception occurs when larger particles directly collide with a fiber. When a particle’s inertia contributes to its collision with a fiber, then this is referred to as inertial impaction.

HEGA Filters

You may also have heard of HEGA or High Efficiency Gas Adsorber filters. Particular to Austin Air, HEGA filters have to demonstrate a minimum efficacy of 99.9%, per criteria of the Institute of Environmental Sciences, also use « adsorber » filter to filter out chemicals, gases, and odors.

Adsorber filter combines carbon or carbon/zeolite pellets into a carbon cloth filter to trap gaseous particles. Particular to the HEGA filter, the adsorber filtration system must be designed, assembled, filled and packaged to adhere to these specific standards. The HEGA air filter should also remove irritants like pollen, dust, mold spores, bacteria, and pet dander to be regarded as a HEGA filter.

 

The Austin Air Allergy Machine Series comprise HEGA filtration. Austin Air discovered and developed the new HEGA technology, which entails weaving carbon into a lightweight fabric. The Austin Air Allergy Machine is the ideal air purifier for somebody who wants to remove gases, vapors, and odors as well as allergens and other particulate matter.

Activated Carbon Filters

Activated carbon filters remove gases, odors, and chemical toxins. Carbon, or activated charcoal, is treated with oxygen to open up the millions of tiny pores between the electrons.

The activated charcoal adsorbs odorous compounds from gases or fluids. The term « adsorbing » refers to the way the pollutants attach to the charcoal by chemical attraction. The huge surface area of the activated charcoal gives it tens of thousands of pores for trapping pollutants. As compounds and pollutants pass the carbon surface, they are immediately attracted and captured within the filter.

Some carbon filters are treated with additional chemicals like potassium iodide or potassium permanganate which improve the carbon filter’s ability to catch Volatile Organic Compounds (VOCs) and other chemically reactive gases. Activated carbon filters adsorb a larger array of contaminants.

AllerAir air purifiers utilize an activated carbon filtration system to effectively clean indoor air. AllerAir models feature a cylindrical shape for optimum air flow, an effective four-stage filtration system, and a silent fan.

Electrostatic Filters

Like Activated Carbon filters, Electrostatic filters bring pollutants. Instead of carbon, Electrostatic filters use electrostatic charges to clean the air. Electrostatic charges are created by pushing air through a maze of static vulnerable fibers. As airborne particles proceed past the static vulnerable fibers, they become drawn to the static charge and are recorded inside the filter. The particles remain on table plates until they are hand washed or eliminated by a HEPA vacuum cleaner.

By utilizing static electricity, you can’t need to worry about replacing the filters, because most electrostatic air cleaners use collection plates to capture pollutants and can be washed easily. On the other hand, the collection plates must be cleaned frequently to make sure effective air cleaning. Additionally, unlike HEPA filters, some electrostatic filters emit ozone, a dangerous lung disease that can trigger asthma and asthma symptoms, in addition to other respiratory issues.

Procuring an air cleaner which does not emit any ozone increases the amount of truly clean air in your property. Friedrich air purifiers have the best electrostatic filter in the marketplace and emit minimal amounts of ozone.

Charged Media Filters

Charged media filters also utilize electrostatic energy. Made from synthetic fibers, the press filter is charged via the production process and keeps the charge during its usage. This charge attracts airborne particles, giving them an electrostatic charge before trapping them within the fibers of a conventional filter.

Social media filters present relatively low energy prices and are really efficient. However, as the filter becomes bloated, it will become resistant to the airflow, making it less effective the longer soiled it’s. Therefore, charged media filters must be changed regularly for peak performance.

Charged media air cleaners have been famous for their energy-efficiency and quietnessnonetheless, some of them might emit ozone. Blueair air purifiers utilize the best charged press filtration, do not emit ozone, and are very quiet and efficient.

Hybrid Air Filtration Systems

The Hybrid air filtration system optimizes its effectiveness through the utilization of numerous technologies. Hybrid air purifiers use a mix of filtration procedures, each filter comprising to the general effective quality of the air purifier. Most effective air purifiers a use mixtures of the filters listed above.
