How many days was it again? 30? 100? — The general consensus is that you should replace your home's air filter every 3 months or 90 days. But what happens if you let that time go by a little? Before we talk about WHEN the air filter should be changed, let's start with the WHY. However, changing the filter every 30 days is a hassle.
In spring and autumn, the filter usually doesn't get as dirty because there's not as much need for heating and cooling, so you can get by without changing it as often. And in a home that doesn't have a lot of infiltration or leaks in the ducts and a low level of dust in general, the filter can stay clean longer, even when used a lot (unless the return vents are on the floor). The basic consensus among HVAC professionals is that you should replace your oven filter every 90 days or every three months. However, that depends on the thickness of the filter.
Thicker filters have more room to pick up dirt and dust, so there's no need to change them as often. Thomas %26 Galbraith Heating, Cooling and Plumbing of Ohio recommends replacing filters that are less than 2 inches thick every 30 to 90 days. Three- or 4-inch filters can last 6 to 9 months, and filters up to 6 inches thick can be replaced once a year.

According to Bob Vila, the filters are designed to protect the oven from these particles, and improving air quality is only a beneficial side effect.
No matter how long I delayed changing the filter, I could never detect a measurable increase in static pressure. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance. In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. If you live in a “smaller house,” your air conditioners and ovens need to pump less air for the same amount of temperature change, which could mean fewer filter changes.
One of the most important things you can do on your own to take good care of your HVAC system is to simply change your air filter on a regular basis.
