4 Tips for Choosing an Air Purifier
Choosing the right air purifier for your home depends on several important factors, including home size, health and environmental conditions. Many choices are available, fitting within most budgets. The main types of air purifiers include:
HEPA Air Purifiers:
HEPA, or High-Efficiency Particulate Air filters trap microscopic contaminants, eliminating 99.97% of all particles larger than 0.3 microns. HyperHEPA filters remove particles as small as 0.003 microns!
The HEPA filter’s fibers are essential for trapping particles in the air flow. Passing through the filter, the air carries various contaminants. Particles larger than one micron stick quickly to the fibers as the air flows through. Smaller, lighter particles keep “going with the flow” longer before bumping into a fiber. However, the HEPA’s accordion-style pleats create many obstacles, ensuring that even the tiniest particles get trapped by the fibers.
Allergy and Asthma Air Purifiers:
These types of air purifiers are perfect for those who suffer from severe allergies, as they capture airborne pollen, dust and other allergens. They often feature HEPA and/or activated charcoal filtration. Note that air purifiers can’t actually cure allergies or asthma; however, an air purifier designed to filter airborne allergens offers substantial relief by reducing triggers.
An activated charcoal filter works by removing microscopic particles via chemical adsorption. By treating it with oxygen, carbon becomes activated, opening up millions of tiny pores between the carbon atoms. This creates a huge surface area in a small space, perfect for absorbing microscopic contaminants like dust and pollen.
Smoke and Odor Air Purifiers:
Powerful charcoal filters make it easy to eliminate the toughest smoke and/or odors from your indoor air. Living with a smoker may be a fact of life for many people, but living with smoke doesn’t have to be. The home environment can be purified and kept fresh with an air purifier designed to eliminate smoke and odor-bearing particles.
The Mayo Clinic states that secondhand smoke is related to low birth weight, sudden infant death syndrome (SIDS), childhood asthma, bronchitis and pneumonia.
The Centers for Disease Control and Prevention (CDC) also reports that lung and heart disease from secondhand smoke kills over 41,000 people annually. These are strong reasons for using an air purifier.
Medical Gas and Chemical Air Purifiers:
Medical-grade purifiers eliminate gas and chemical pollution. Many medical conditions require a vigilant strategy of purifying the air to reduce health risks and improve overall comfort. Elderly people, those with compromised immune systems and chronically ill individuals are especially vulnerable to airborne toxins. Medical-grade purifiers eliminate chemicals and emissions, improving the home environment and quality of life.
