Are Electrostatic Air Filters Worth the Investment?

Electrostatic air filters are an effective way to filter out allergens from the air, such as dust, pet dander, and mold. The initial cost of an electrostatic filter may be high, but it will quickly pay for itself with the cost of replacing filters and shipping costs if you buy air filters online. Electrostatic filters are the clear winner when it comes to air filtration. Fiberglass filters are very economical, but they can only remove large particles from the air and offer little or no effect on improving air quality.

An electrostatic HEPA filter can offer additional benefits. Electrostatic filters have a slightly higher initial cost, but over time they save money, hassle, and frustration in maintaining your HVAC system. Your electrostatic air filter will save you money after just one year of buying it. Not only that, but because you wash and reuse the filter, they don't generate waste for the landfill.

These filters can be recycled by replacing the heating and cooling system. What makes this process so efficient is that the electronic air filter effectively removes microscopic impurities from the air, such as pet dander, dust, pollen, smog, smoke, and mold spores. All of these may be seemingly harmless, but they have the potential to make you and your family sick. When a traditional pleated filter starts to get dirty, it actually becomes more effective in a sense, as particles will have a harder time breaking through. Third, although electrostatic filters help remove dust and other pollutants from the air, they are not as effective at fighting allergies as other filters on the market. Oven air filters use a rating system called MERV (Minimum Efficiency Report Value) that rates the overall effectiveness of a filter on a scale of 1 to 20.

Instead of having a frame made of thick cardboard, the frame of an electrostatic air cleaner is constructed of aluminum. You can assume that the air filter that comes standard with your HVAC system is enough to combat this, but that's not the case. The original purpose of a fiberglass filter was to prevent debris from entering the oven; these filters were never intended to improve indoor air quality. Depending on the quality of the electrostatic filter, this process can be repeated several times before the air is cleaned and returned to your system. If you have asthma, allergies, or other respiratory illnesses, it is extremely important that indoor air is as clean as possible. Disposable filters come in several different styles, such as fiberglass, pleated, and disposable electrostatic.

Fiberglass filters need to be replaced every few months and are capable of filtering large particles such as lint, dirt and dust. As the air enters the filter, it receives a positive charge; as the positively charged air travels through the next layers of the filter, the charge is released and traps the particles inside the filter. Disposable pleated filters are made of polyester or a cotton paper blend with a rigid cardboard frame. By the time you remove a dirty traditional filter from your heating and cooling system, it could release dust everywhere. HVAC manufacturers have been testing the effectiveness of filters in protecting people from contracting Covid-19. The Centers for Disease Control (CDC) recommends improved air cleaners and air purifiers to improve indoor air quality (IAQ) and combat Covid-19, especially for people with respiratory diseases.
