Electrostatic air filters are a popular choice for many homeowners, but are they really safe? Unlike HEPA and pleated air filters, electrostatic filters cannot block pathogens, and if not cleaned regularly, they can damage HVAC airflow. Additionally, many electronic air purifiers release ozone as a by-product, which can be harmful to indoor air quality. In this article, we'll explore the advantages and disadvantages of electrostatic air filters and discuss whether they are suitable for your home. The primary benefit of electrostatic air filters is that they provide good air filtration.
The electrical charge captures charged dust particles, bacteria, viruses, pet dander, pollen, and other particulates that float around your home. This keeps your home cleaner and more pleasant, and you won't have to dust as often. Both metal mesh and synthetic electrostatic filters are washable, but metal mesh filters are more durable. Another advantage of electrostatic air filters is that they can help reduce your utility bills. The filter helps your heating and cooling system operate at the highest level of efficiency.
However, it's important to note that air filters that use ions, oxidation or ozone should be avoided. It's also not recommended to operate the air conditioning system without a filter while the electrostatic filter is drying. Ultraviolet irradiation can improve indoor air quality in your home, but probably not as much as the person who sold you the UV lamps told you. You can find normal filters with a low MERV rating between one and four, but these filters also come with higher MERV ratings. If you have asthma, allergies, or other respiratory illnesses, it's essential that your indoor air is as clean as possible. Electrostatic filters can help with this, but it's important to make sure you get the right size for your model.
If you don't find the right size for your model, you can contact most companies to create a custom filter for you. In conclusion, electrostatic air filters provide good filtration and can help lower utility bills. However, they cannot block pathogens and should be avoided if you have respiratory illnesses. Additionally, many electronic air purifiers release ozone as a by-product which can be harmful to indoor air quality. Therefore, it's important to consider the pros and cons before deciding if an electrostatic filter is suitable for your home.
