Most people seem to be triumphant with using standard air filters for their HVAC system, while it is true that in most cases standard air filters will do the job just fine, under particular circumstances you might consider using more advanced filters, and but what exactly do these more advanced filters do? Well, it depends on what kind of air filter we’re talking about, first, the standard air filter blocks larger particles like dust, dirt, plus hair.
Filters made of spun fiberglass are the absolute cheapest, however they are also the least efficient… Other basic filters are made of cardboard plus paper, which provide a bit more efficiency, however not much.
Both of these types of filters are meant to be disposable, plus there’s no real point in attempting to scrub them; you just update them, and hEPA filters are far more effective at trapping both larger plus finer particles. HEPA filters boast the ability to block 99.97% of contaminants in the air. HEPA filters are disposable as well, however they do not need to be updated nearly as often as the other kinds of cheaper air filters, however surprisingly, HEPA air filters only need to be updated every 6 to 12 months compared to cheaper air filters that may need to be updated as often as once every two months, however more often, once every 90 afternoons. Finally, you have reusable air filters, which are far more efficient plus permanent; These air filters are also known as washable air filters, or electrostatic filters. True to their name, electrostatic air filters use static electricity to attract foreign particles. Though they are far more efficient plus permanent, you should scrub them once every thirty afternoons.
