Everyday, dust mites feed off the 30,000-40,000 dead skin cells the body sheds every minute, but before they can, mites need dust to mature.  And one of the biggest methods for preventing dust from entering a home is a clean A/C or heater filters.  Even worse, old and worn-out devices can cause heavy loads of dust, lead to allergies and even asthma flare-ups. If you’re in the market for a new filter, here’s a quick guide for understanding the differences and usages for each one.

 

Fiberglass and Polyester

 

Considered the cheapest of the four, fiberglass and polyester capture large particles like lint and dust. However, because of their inability to capture smaller objects—like pollen or dander—people with sensitive noses can still experience discomfort. Still, because of their inexpensiveness and simplicity to dispose of, most people will choose these types of filters.

 

Washable and Reusable

Upping the purchasing cost, washable filters provide a convenient solution to protecting homes against large particles. Ideal for either furnaces or air filters, these products can be used for years, so long as they are cleaned regularly. For example, a replacement honeywell air filter can last a few months or a few years if the filter is washable. Disposable options also exist if the goal is immediate cost-savings.

 

Pleated

Compared to the previous two, pleated filters are easily disposed of while capturing larger particles through its mesh lining. Typically, pleated filters work well with protecting a household against dust mites and lint, but against smaller objects, like virus carriers, smog and smoke, these filters prove futile.

 

Electrostatic

Electrostatic filters offer protection against small and large particles, but compared to the others, requires constant changing to maintain its effectiveness. Still, an electrostatic furnace filter or an A/C unit will ward off pollen, smoke, smog, virus carriers and even mold. For individuals with intense allergies or asthma attacks should consider investing in electrostatic filters. The added quality ensures the best possible air quality with the fewest possible pollutants.

 

While each of the four provides its own advantages and disadvantages, they all help ward off some type of pollutant that can further aggravate asthma or allergies. Depending on your sensitivity to pollen or dust, you may not need an expensive filter. And to further prevent any flare-ups, ensure to clean your sheets, remove any carpeting and ensure carpets are vacuumed regularly.
