Generally most filters should be changed every 1-2 months. Your filter may need to be changed more often than this depending on the quality of air in your home
It is a good idea to regularly inspect your filter for signs of dirt and/or damage. If it looks dirty, then it is no longer doing its job and needs to be replaced.
Other filters, like the 4" pleated filter, need to be changed less often, approximately every 4-5 months.
Electronic air filters never need to be replaced! However, these filters should be cleaned regularly. Our Planned Maintenance customers will automatically receive this service during their scheduled appointment.
