How Often Should You Change a 5 Inch Filter?

A good rule of thumb is to change 1-inch to 2-inch filters every three months, 4-inch filters every six months, and 5-inch filters every 12 months. For 3- and 4-inch filters, plan to replace them approximately every six to nine months. If you have filters larger than 5 or 6 inches, you'll need to change them every nine to 12 months. Filter manufacturers offer guidance on when to change your home's air filter, which is usually included with the filter you buy.

Even if no one in the house is allergic, it is advisable to change the oven filter frequently, up to every 30 days if you have several pets, so that the oven works efficiently. During a remodeling project, replace the furnace filter every 30 days, or even more frequently, to prevent construction-related dust from circulating around the house. Rather than simply going outside the standard schedule, here are some special signs and considerations that will let you know when to change an oven filter.

Generally speaking, HVAC oven filters don't need to be changed as regularly during the winter months compared to the summer months. We also offer filters for 5-inch ovens (16x25x5 or 20x25x), brands of air filters for the whole house and filters for rigid cell ovens.

Marking the calendar every 90 days or trying to remember the last time you changed your filter can be a challenge, so many oven manufacturers recommend replacing them at the start of each new season. One- to two-inch filters can increase every month, 4-inch filters every two months, and 5-inch filters every six months. To help solve the conundrum, here's information on how often you should change your oven filter. How often you should change your oven filter will depend on the type of material and the efficiency of the filter you select. It is also recommended that you check the filter monthly to monitor its condition, as certain factors specific to your home, home and HVAC system override this schedule and require that the filter be changed more frequently.

You may not have realized that you need to change your oven filter because oven filters aren't needed in every HVAC system. As a general rule, to keep allergy sufferers as comfortable as possible, change the oven filter every 30 to 60 days.
