What Are The Cons?
They can only filter out so much from your air. Electrostatic air filters aren’t going to filter out as many allergens and debris as anti-allergen filters do. This is something to keep in mind for your own home. If you or someone in your home suffer from airborne allergies, you may want to steer clear from this product. It won’t protect you as well.
They operate on static electricity. This means that they will only pick up light dirt and debris so long as they have that electricity. This means mold spores and larger bits of debris will still get through. They are good at what they claim to be, however, they cannot compare to a good quality HEPA filter.
If it isn’t washed regularly, it can become a playground for mold and mildew. These filters need to be washed monthly at least to get rid of any buildup of dirt or debris. If you do not keep that up, then mold and mildew can grow. Especially if you do not let it dry completely before reinserting it. This combination of wet filter and dirt will definitely lead to problems.
Electrostatic air filters block airflow more than regular filters. This means that your furnace will have to work twice as hard to get the same amount of airflow out of the machine. This can cause wear on its parts and the machine itself, leading to repairs and maintenance calls to fix it. It’s important to consider this when buying one.
