Electronic Air Cleaners and Indoor Air Quality
A large electronic air cleaner (ea-clean) is a portable electrostatic air cleaner that is powered electrically and blows out air through a filtering pad to remove large particulate matter from the air. Electronic air cleaners are most often intended for cleaning larger areas like offices, hospitals, warehouses, or apartment buildings where the air quality is significantly less than in large commercial centers. An electronic air cleaner has many benefits over other types of electronic air cleaners. These benefits include:
The electronic air cleaner passes an ionizing charge through the air. The particles, attached to the charged plates, are excited and discharge to the outside atmosphere. The negative ions created in the process remove larger particles than positive ions, thus making it a safer filter than other types of filters. This is because one type of ionization produces more negatively charged ions than positive ones.
This type of filter is more expensive than a typical ionizer but has a longer life span. One disadvantage of an electronic air cleaner is that it only works on particles that have a charge. Other types of filters that work by releasing airborne particles only when the filter becomes wet can also work better than a stationary ionizer. The electronic air cleaner will also need to be constantly recharged because airborne particles tend to become damp over time. However, this advantage allows the electronic air cleaner to be used in places that do not have electricity or other sources of power.
One of the benefits of using an electronic air cleaner is that it can target specific pollutants or allergens. It works by passing an electrical current through moistened plates which then attract airborne particles. The charged plates pass the charged particles onto a filter containing electrostatic precipitators that traps the pollutants or allergens.
There are many different types of electronic air cleaners and each has its advantages and disadvantages. For example, electrostatic precipitators are used in many types of filters to trap larger particles such as dust. However, this method can sometimes clog larger than normal filters. Some homeowners use electrostatic precipitators on their own to clean their homes, even if they have a clean air filter. However, this method can also be dangerous, as the homeowner could easily shock their family with static electricity. Also, the large number of small particles that can accumulate in a large electrostatic precipitator can create very bad odors.
Another type of electronic air cleaner uses a combination of air filters. Some electronic air filters clean the air via electrostatic attraction, while others use magnetic induction. This method is also not without its flaws. Electrostatic attraction does not catch all the particles in the air, as dust and pollen are attracted to a magnet. Magnetic induction can sometimes create a smoky or clouded view of the room if a sufficient charge is applied to the filters. In addition, the presence of magnetic fields can interfere with the operation of some electronic devices.
Many manufacturers of residential and commercial HVAC systems incorporate the use of electronic air cleaner systems into their systems. Some of the most popular brands include; Honeywell, Whirlpool, GE, Hoover, and Valves. The electronic air filters are usually mounted on airflow plates situated between two ductwork panels. These plates catch the air as it passes through the ducts and the air is then collected by the plates and transported to a central location.
The air is then compressed by an electric motor to remove any moisture present. The compressed air is then released through the vents to the outdoor control panels. Some electronic air cleaners and air filters use airflow plates that are mounted on the ceiling or other obvious locations in the home. The plates can also be fixed to walls to increase the overall ventilation of a room. In addition, electronic air cleaners use special nebulizers that convert water vapor into dry air.
