The health benefits of using an air purifier are many. To begin with, they remove pollutants from the air. They also remove microns fro the air. These two factors alone leave the air cleaner and easier to breathe.
Many of the models that are available also use a HEPA filter. These filters remove impurities from the air. Individuals with breathing issues and allergies have attested that using a purifier with a HEPA filter have virtually eradicated their symptoms.
Another benefit that has been overlooked is that purifiers can cut down on the amount of housekeeping that must be done. In removing impurities and dust from the air, people have to clean and dustless. This frees up more personal time allowing for the easing of stress and the full relaxation of the individual. The lack of pollutants in the air also protects furnishings from aging faster.
One disadvantage of having an air purifier is that they tend to need frequent cleanings in order to maintain optimal benefits. Some units have also been found to produce ozone and ions in the air. Many of these models have been removed from the market.
