While air purifiers may not directly or immediately improve a person's health, studies indicate that these devices can help reduce exposure to harmful contaminants, which may have long-term health benefits. But will you feel something different? Hopefully, yes, and perhaps in more ways than one. A small-scale study conducted in China found that air purifiers reduced fine particles in the air (dust, pollen, dandruff) and improved participants' blood pressure levels and lung function. If you are thinking about buying an air purifier, you should know that it will not remove all harmful particles of your home.
A lot of particles can remain on soft surfaces (furniture, carpets, bedding, etc.). However, when used in conjunction with a filter and regular cleaning around the house, an air purifier is a fantastic way to improve air quality and your health. The EPA states that portable HEPA air filters have been shown to be beneficial for allergy and asthma symptoms, as well as cardiovascular health. Unfortunately, air purifiers are not designed to eliminate mold, nor can the devices eliminate musty odors associated with mold. They use fans to draw air through one or more filters, trap various contaminants, and then circulate cleaner air back to the room.
Air purifiers promise to clean the air in your home by removing airborne contaminants, such as dust, pollen, and smoke particles. An alternative type of air purifier uses ionizers instead of filters to create a static charge around particles, effectively reducing the amount of particles circulating in the air. But make sure your air purifier also has a HEPA filter to remove particles; a carbon filter alone won't trap dust or pollen. Fortunately, whether your suffering is due to pollen in the air or your boyfriend's cat sitting on your lap, an air purifier can provide some relief.
You'll never know how polluted the air inside your home is until you use an air purifier and see the particles accumulated in the filter. Air purifiers can help clean the air in the home from unwanted particles, such as pet dander, allergens, and smoke. For an air purifier to qualify as “suitable for medical use”, it must be able to prevent the smallest types of particles from penetrating, such as Viruses. Fine PM2.5 particles, the term for the smallest particles of PM2.5, cause most health problems because they can penetrate human airways and enter the air sacs of the lungs. Household air purifiers are becoming increasingly popular, especially as people are more concerned about the environment and air quality in general.
While a purifier doesn't replace prescription medications, it can help eliminate the problematic source of many allergy symptoms. He commented that, due to the turbulence they generate, for an air purifier to have a real impact it would have to be located a very short distance away.
