It depends on what you mean by 'work. ' They do remove some dust particles from your air, but overall I do not recommend electrostatic air filters for home use. Electrostatic air filters are an interesting technology but they just won't work as well as a 3M 1600 MPR and they never will.

Keeping this in view, are electrostatic furnace filters better?

Disposable electrostatic filters typically have a higher MERV rating making them a good choice for individuals with children, pets, and smokers. Electrostatic Filters vs High-Efficiency Pleated Filters - If your furnace is capable of using a high-efficiency pleated filter, these are an excellent choice.

Beside above, are reusable furnace filters any good? Disposable air filters are more effective at trapping small particles. Washable air filters are typically only good at protecting from large particles like dust. They do not effectively filter out pet dander, bacteria, viruses or smoke, especially when they're not meticulously maintained.

Just so, how effective are electrostatic air filters?

Not as Effective as HEPA Filters Since electrostatic filters essentially rely on static electricity, they can filter out the small and lightweight particles easily. However, they cannot get rid of finer mold spores or dust particles. In other words, they are not as efficient at purifying the air as HEPA versions are.

Are electrostatic filters safe?

Ozone: Electrostatic air filters do NOT protect against ozone and even have the potential to produce ozone molecules which can aggravate asthma and damage the lungs. Air Flow: If these filters are not cleaned regularly they have the potential to have a negative impact on air flow.

Do electrostatic air filters actually work? Answer: it depends. Electrostatic air filter devices do work fairly well to filter allergens from the air, because they filter particles like dust, pet dander, or mold, which are the usual suspects when it comes to allergies.

Do electronic air filters create ozone?

Ozone emissions
