Do Electrostatic Filters Need to be Replaced? - An Expert's Guide

It's a good idea to replace pleated filters every 90 days, and if you have electrostatic or washable filters, you should clean and reinstall them once a month. Washable filters are more eco-friendly and, if properly maintained, can last up to 10 years. However, the Molekule air purifier may be a better long-term investment, as it can remove harmful gases and allergens like mold, so they never accumulate in the filter. Electrostatic air filters are effective at filtering out allergens like dust, pet dander, and mold, which are often suspected of causing allergies. The 100 to 300 MRP filters trap lint and dust, the 600 MRP filter pollen and mold, the 1200 MRP remove smoke and smog, and the 1500 MRP offer limited protection against viruses.

The term “electrostatic air filters” can refer to either an air purifying unit that uses electricity to charge particulate matter or a disposable filter panel that is normally placed in a heating, ventilation, and air conditioning (HVAC) system. Both types of filters have their pros and cons, but washable electrostatic home air filters are a smart choice that can help you save money in the long run. Some companies have started testing whether air conditioning filters or air purifiers can protect you from coronavirus. As the filter is made of metal, it is reusable, so there is no need to change them every few months like with a normal filter. The carbon filter is used to remove remaining impurities, allowing fresh, clean air to enter your home.

Electrostatically charged filters are considered “flat” filters, unlike pleated filters such as HEPA filters. Air filters receive a Minimum Efficiency Value (MERV) rating, which indicates their efficiency. To start cleaning your electrostatic oven filter, remove it from the filter grid near the unit's air handler. Although they look like something from George Jetson's Skypad apartment, in reality electrostatic air filters are fairly simple devices that rely on basic scientific data to help clean indoor air. Depending on your budget and your particular allergies, a HEPA filter or a Molekule device may be a viable option for reducing allergen levels in the air. To clean your electrostatic filter, rinse it until the water through it is clear.

Then find a place to prop up the filter to let it dry. Electrostatic air purifiers promise to remove dust and other particles from the air with an ingenious trick of electromagnetism. However, an electrostatic air filter unit should be avoided because of the potential ozone it can produce.
