How Often Should You Replace or Clean Electrostatic Air Filters?

Electrostatic air filters are a great way to improve indoor air quality and make the air in your home safer to breathe. They are reusable, so there is no need to replace them every few months as with a normal filter. You have to wash the electrostatic air filters, which can add another task to your to-do list. On the other hand, disposable electrostatic air filters must be replaced every one to three months, as they have a shorter lifespan.

Low-cost fiberglass filters need to be changed every 30 days. Pleated air filters are a bit more expensive, but they can last up to 6 months. A good rule of thumb is to replace pleated filters every 90 days. If you have electrostatic or washable filters, you should wash, dry, and reinstall them once a month.

Washable filters are more environmentally friendly and, if properly cleaned and reused, can last 5 to 10 years. An electrostatic filter is generally rated no higher than 5 or 6, while other high-efficiency filters have ratings between 10 and 16 and even higher. This charge attracts dust and dirt particles like a magnet and holds them until the filter is clean. It could cause further damage to the system (freezing of the coils, formation of liquid in the air compressor or heat pump). Although it seems like it's just another thing to add to your to-do list, cleaning an air boiler's electrostatic filter is actually quite a simple task. Use a garden hose to spray the filter in the direction opposite to the airflow, which should be its cleanest side.

HVAC system manufacturers have been testing the effectiveness of filters to protect people from contracting the virus. Therefore, once the first particles are trapped, another layer re-creates a positive charge in the air. The reason why types of electrostatic filters don't need to be replaced frequently is because they work in a completely different way than HEPA filters.

To determine if an electrostatic filter is right for your residential or commercial air conditioning system, it's important to learn more about it and how it differs from HEPA filters. If you're having trouble removing particles with just water, use a clean rag to clean the filter after you spray it. If you have a spray nozzle, turn it to maximum pressure and spray the entire air filter thoroughly, thus removing all the dust and debris trapped in the filter. It's important for homeowners and business owners alike to understand how electrostatic air filters work and how often they need to be replaced or cleaned. Cleaning an electrostatic filter is an easy task that can help improve indoor air quality and make sure your HVAC system is running efficiently. By understanding how often these types of filters need to be replaced or cleaned, you can ensure that your HVAC system is running efficiently and that your indoor air quality is at its best.
