Air filters are rated according to their Minimum Efficiency Report Value (MERV) rating, which indicates their effectiveness in capturing particles in the air. Electrostatic air filters have a MERV rating between one and four, and can capture less than 20% of the dust. When it comes to air filters for HVAC systems, electrostatic filters are the clear winner. Fiberglass filters are economical, but they can only remove large particles from the air and offer little or no effect on improving air quality.
Each type of filter has its own advantages and disadvantages, depending on the purpose for your home. If you need an HVAC system filter that keeps the air free of allergens and other contaminants, or just a basic filter to get the job done, you'll want to consider factors such as cost, whether there are pets in the house, if mold or mildew is a threat, and how often filters should be changed. It's wise to talk to an HVAC professional before making any decisions about air filters. Media filters provide the same level of filtration as a high MERV filter, but without the negative consequences of airflow or static pressure.
They have a larger surface area, which successfully avoids significant static pressure and provides better filtration. An electrostatic air filter is also washable and reusable, so you don't need to have a stack of disposable filters on hand to replace them on a monthly basis. A well-built, washable electrostatic air filter is designed to last longer than the HVAC system itself. It is made of a non-porous filament that does not absorb or retain ambient moisture, and is impervious to mold, bacteria and fungi.
It also addresses environmental concerns associated with disposable air filters. EPA uses four measurement standards to determine how well an air cleaner can remove particles from the air. UV filters are excellent for killing microorganisms that could be hazardous to health, including mold spores. An electrostatic air filter is a washable filter that traps dust and other particles to keep the air clean.
MERV (Minimum Efficiency Report Value) is a standard that rates the overall effectiveness of air filters. If you're still not sure which one is best for you and would like to learn more about these oven filters, call Simply the Best Heating & Cooling and we'll be happy to give you more information and help you make the most informed decision for your home air filtration system. To work effectively, air filters must be replaced or cleaned every 4 to 6 weeks (depending on the individual application). Pleated filters should be changed every 3 months, while electrostatic filters should be cleaned monthly. Because static electricity remains constant over time, these filters will never lose their electrostatic properties, regardless of how long they are used or how often they are washed. In conclusion, electrostatic air filters are an excellent long-term investment for someone who doesn't have strong preferences about HVAC filter types and doesn't need any special filters.
They provide more benefits than standard filters with high MERV ratings, while also addressing environmental concerns associated with disposable air filters.
