“I know that our bodies were made only to thrive in pure air, ” stated John Muir, the famous American naturalist over a century ago. Though great advances in transportation, communication, and science has changed the world much since he made this observation, the need for pure air has not changed. Human beings still need clean, unpolluted air for the best health and life, and modern society has found an effective tool to make this possible–the air purifier or the best air purifier for pets in case they have pets allergy.
Health Benefits of Air Purifiers
The average person breathes in 2000-3000 gallons of air daily, which fuels every system in the body. Just as an automobile benefits from its built in system of air filters that enable it to run efficiently, so too the human body benefits with the help of a system to provide clean air such as an air purifier.
First, air purifiers remove allergens from the air. Some experts estimate that almost 25% of people suffer from certain respiratory allergies caused by airborne agents like pollen, dust, and mold. While many of these allergies only cause discomfort and mild irrigation, the number of life-threatening reactions have increased greatly in recent years. For example, the CDC reported that there were 3630 deaths due to asthma in 2013.
A second benefit of air purifiers reduction of respiratory illnesses. Experts estimate that over 6 million work and school days are lost each year due to allergies, and $17.5 billion is spent on allergy medicine. Yet, when a person uses a air purifier in the home consistently, it can remove dust, smoke, allergens, and viruses that are the root cause of such costs.
Finally, air purifiers reduce the cleaning costs of the normal household. In 1970 Americans spent $45 million on furniture polish. When operated regularly, a purifier removes dust from the home’s inner atmosphere, reducing the need to clean furniture and woodwork as often. Also, since purifiers serve to remove odors from the air, carpets, furniture, and draperies remain odor free and the homeowner can avoid costly steam cleaning.
Important Air Purifier Features
Two important features of air purifiers are the type of filtration system and the air moving capacity. There are five main types of methods purifiers use to clean the air: mechanical, UV light, ionization, electrostatic systems, and hybrid systems.
A second aspect is a purifier’s air moving capacity. Purifiers are rated by two measurements for this feature: air change rate per hour (ACH) and clean air delivery rate(CADR). ACH measures how many times the purifier cleans the room’s air in one hour. CADR measures how much cubit feet of air the purifier can clean in a minute in the area of pollen, dust, and smoke.
A third important feature to consider is the noise produced by the purifier. Noise from air movement, fan operation and motor vibration varies greatly from model to model. Generally, the more expensive purifiers operate quieter than lower priced models.
A final useful accessory is a filter alert. While this is not included on some purifiers, better models include an automatic sensor and notification system such as a light that alerts the owner when the filter needs to be replaced.
