Electrostatic air filters are an excellent choice for those who need a filter that can effectively combat allergens. These filters use tiny cotton and paper fibers to generate static electricity, which acts like a magnet for dust and other particles suspended in the air. This magnetism is strong enough to prevent these particles from spreading throughout the house. Although electrostatic filters have a slightly higher initial cost, they save money, hassle, and frustration in the long run when it comes to maintaining your HVAC system. Fibreglass, polyester, washable, pleated and electrostatic filters all offer different air filtering capabilities.
Electrostatic filters provide the highest level of filtration for small particles. An electrostatic air filter is designed to trap smaller particles more efficiently than standard air filters. These filters are available as disposable and washable options, and can be sprayed with a mild household cleaner to remove any grease or smoke residue. The Centers for Disease Control and Prevention (CDC) recommends improving filters and air purifiers to improve indoor air quality and combat COVID-19, especially for people with respiratory diseases. If your family doesn't have a respiratory illness, you're a practical homeowner and don't mind cleaning the filter, then an electrostatic air filter can save you money while keeping your home clean.
The starting price of this type of air filter for air conditioning systems is high, but it must be considered an investment that will last for many years. The particle is trapped before releasing its charge as the air passes through subsequent layers of the filter. In addition to filter resistance, the Filter Performance Rating (FPR) also indicates what type of air contaminants are ideal for capturing each filter. High-efficiency filters that are also cost-effective are usually best suited for homes, but you also need to consider if there are pets in the house, if mold or mildew pose a threat, and how often filters should be changed. The smallest amount of moisture that remains can cause mold and mildew to form on the filter and expel them into the air you breathe. The downside of these filters is that they require the HVAC system to work a little harder to suck air through the unit, which can cause the HVAC system to lose efficiency sooner than expected.
