Can Air Filters Help With Allergies

Many people suffer with allergies and are eager to take any steps to help prevent or alleviate their symptoms. Over recent years, air filters have become more common in the home as a preventative measure. There are conflicting reports on the effectiveness of air filters for allergies, but most people find them to be helpful in reducing the flare-ups and symptoms of allergies.

There are several different types of air filters on the market today. Each type is supposed to work by cleaning the air of harmful particles and allergens that can be irritating to humans. Mechanical filters force air through a special mesh that traps particles like pet dander, pollen and dust mites. They also can capture harmful substances like cigarette smoke. A popular type of mechanical filter is a HEPA filter. To qualify as a HEPA filter, the filter must be able to capture 99.97% of all particles 0.3 microns in diameter or larger.

Electronic or ion-type filters utilize electrical charges to attract particles into the filter. The particles are then contained within a collecting plate. A disadvantage to this type of filter is that it releases an ozone byproduct. There is a hybrid filter which is a combination of the mechanical and electronic filters.

Gas phase filters do not remove particles, but remove odors and other non-particulate pollution. This type of filter can be effective for people who have asthma that is triggered by smells. Cooking odors, paint fumes and perfume are some odors that can be removed by this type of filter.

At present, there are no standards that have been issued on air filters. It is important that consumers research the claims and demand proof that the manufacturers' claims can be substantiated when comparing air filters. Some air filters are considered class II medical devices, meaning that they have been found to be safe and have a medical benefit.

There are many things to consider when purchasing an air filter. Where will it be used in the home? Air filters are available that clean one room or multiple rooms. Portable air filters are available that can be moved from room to room. The noise level of an air filter is also an important consideration. Air filters that are overly loud can impede sleep or rest. Consumers should also consider the maintenance of air filters. Filters within the device must be changed regularly to ensure proper function. The ease of changing the filter, in addition to the cost of the filters, should be researched.

A very important factor to consider is what substances the filter will remove from the home. Manufacturers do not have to prove their claims, but a reputable product will have studies and data that will support any claims that are made. Price is another factor that must be addressed. Air filters can be found in a wide range of prices. The most expensive air filter may not be the best air filter available and, likewise, the cheapest air filter may not meet the consumers needs.

Through diligent research and comparison, consumers should be able to find an air filter that is affordable and beneficial to their health.
