Allergy Air Filters Review (Asthma)
Electronic and Mechanical Purifiers
If you sniffle and sneeze your way through the year; installing an allergy air filter is one way to bring instant relief. Poor air may not be the sole cause of your complaint (you may have to also think about keeping pets outdoors and putting a ban on indoor smoking), but clean air will go a long way to alleviating allergies and asthma.
Today more people than ever are suffering from the debilitating effects of asthma and allergies. The reasons are manifold, but the finger of blame is most commonly pointed at the rise in airborne pollutants.
The air that we breathe contains microscopic particles which are invisible to the human eye; many of which are potential irritants, such dust and pollen. However, what’s really interesting is that the Environmental Protection Agency has recorded an average of between two and three times as many pollutants indoors compared to outdoors. Hence, it’s easy to see why “allergy free” air filters are becoming an increasingly commonplace feature of people’s lives.
“Allergy free” air filters come in all shapes and sizes (depending on which particles you want to remove from the indoor environment); but basically function in one of two ways:
Mechanical filters work by forcing air through a screen that traps the particles. They remove most irritants, including: dust, smoke and pollen. The most well known mechanical filter is the HEPA filter, which captures a minimum of 95% of the particles that pass through it.
Electronic air filters work by creating an electrical charge to attract airborne particles which are then collected in a designated plate. Electrostatic filters are a simple way of removing potential allergens and work especially well when combines with a circulatory fan.
If you’re thinking of investing in an allergy air filter is worth doing as much homework as possible before making any firm commitments. Combine your research with a visit to a physician or an allergy specialist to establish which irritant triggers your reaction. And remember with 40-50 million allergy sufferers in America alone, there’s plenty of help at hand.
