Even the best HVAC (heating, ventilation and air conditioning) systems cannot completely control the air. Moisture has a tendency to get into homes and businesses, even when windows and doors are well-selaled and walls and floors are well-insulated. Moisture causes mildew and mold, the odor of which quickly spreads throughout a home that has central air.

Once in the ventilation shafts, it can be difficult and expensive to get rid of, often requiring a professional HVAC cleaning service. Other things like pollen, germs, and irritants like tobacco smoke can be carried around the home in the same way. These all cause discomfort, allergies, and other health problems for family members and pets. Under extreme circumstances, some of these can even be life-threatening.

However, a good air purifier solves most of these problems before they begin. Below is a list of the many benefits they provide homes and businesses a like.

The first line of defense in a good electronic air cleaner is direct, chemical-free air filtration. Whether close to the source of the problem or in proximity to the affected person, filtration eliminates most odors while blocking airborne particles before they can spread. Filtration techniques include activated carbon, a safe, natural system that traps dangerous chemical molecules, and specially-designed HEPA (High-Efficiency Particulate Arrestance) filters.

The next defense is air purification. This includes many methods. The newest include polarized-media electronic air cleaning (which charges bad particles and traps them through electromagnetism), ionization, and photo-catalytic oxidation (PCO, which blocks impure air). Other methods include titanium dioxide nanotechnology and ozone generation.

Most state-of-the-art purifiers include silent or near-silent running modes. They are also high efficiency and low energy, making them greener than earlier generation products. Remote activation and atmosphere-based automation allow these items to work while the no one is there, or be operated through smart home technology.

Air purification is also a mainstay in cleaning technology. Vacuums, steam cleaners, and other electronic sanitation products employ HEPA technology as well as other amenities that reduce allergies, eliminate odors, and eradicate dangerous airborne and surface toxins.

When looking for the best product, customers should take into account the dimensions of the room in which it will work (including the room's height). The total space of the home or business may mean more than one purified is necessary. The purifier should have a high clean air Delivery Rate, a measure which was created by the Association of Home Appliance Manufacturers (AHAM). Quality, well-researched air purifiers will provide a family or business with health benefits for years to come.
