Q:

How do electrostatic air filters work?

A:

Electrostatic filters use polypropylene and polyurethane materials that create static electricity when air particles pass through them. The static electricity attracts and traps the air particles in the filter.

Electrostatic filters can remove particles as small as 0.3 microns, which is 1/25,000 of an inch. For the purpose of comparison, a dust mite can be 100 to 300 microns, and staphylococcus bacteria is 0.7 microns. Particles between 0.3 microns and 0.9 microns pose the greatest risk to human health. The problem is that the particles within that range are too small for the tiny hairs that line the nose to filter but large enough that they cannot be exhaled. The health benefits are the biggest selling point of an electrostatic filter. People with asthma or allergies would benefit the most because it traps all of the dust, mites, pollen, mold and plant spores and pet dander.

Electrostatic filters also provide economic benefits. Electrostatic filters can be washed hundreds of times with mild soap and water and reused, according to Networx Systems. Standard paper filters cannot be reused. This equates to less money spent on air filters. The electrostatic filters help keep air ducts cleaner, requiring less money spent on contractors to clean the ducts. This also lowers the amount of dust in the house, which means less dusting. The air conditioner coils are cleaner, meaning that the system runs at optimal efficiency, also saving money in the long run.

  • Q:

    How does an air-cooled chiller work?

    A:

    An air-cooled chiller is a refrigerating system used to cool or dehumidify air by flowing a refrigerant over an evaporator tube bundle. This process draws vapors out of the evaporator and ultimately allows the pressurized refrigerant to condense on a system of tubes and cool the air. When the refrigerant passes through an expansion device, it lowers its temperature. Air-cooled chillers are used in a number of professional settings.

    Can you recycle Brita filters?

    A:

    Brita water filters can be recycled by dropping them off at a Preserve recycling location. Used filters can also be mailed to TerraCycle. Both companies turn used Brita filters into new products. Recycled Brita filters are turned into toothbrushes, watering cans, razors and park benches.

    How do air compressors function?

    A:

    For an air compressor to function, a solitary motor on the compressor converts electrical energy into kinetic energy, according to Popular Mechanics. Compressors increase air pressure by concurrently diminishing the size of the space holding the air, and this is done with two reciprocating pistons. As pistons move down, a vacuum is created above them.

  • Q:

    What temperature should you set your air conditioning?

    A:

    Setting air conditioning to 78 degrees Fahrenheit during warmer months provides adequate cooling while saving on energy bills. For the greatest energy efficiency, allow the temperature to rise while the house is unoccupied and while its occupants are asleep.
