It's essential to know when it's time to change your air conditioner filter. The only way to determine this is by visually inspecting the filter every month. If you can't see through it when you hold it up to the light, it's time to get a new one. There are several signs that indicate it's time for a replacement.
If you can spot dirt on the filter, it fails the “white sheet” test, or you can't remember when you last changed it, then it's time for a new one. Additionally, if you have a new pet or the outdoor air quality has been poor, you should consider changing your air filter more often. Pleated air filters are more expensive initially, but they are more efficient at trapping particulates and can last up to 90 days depending on use. Fiberglass air filters are more affordable but less efficient at capturing dust and particles from the air.
According to the U. S. Department of Energy, replacing a dirty, clogged filter with a new one can reduce air conditioner energy consumption by 5-15%. If you live in a dusty or polluted environment, you should replace your air filter every three months.
Lower home occupancy extends the life of the air filter while higher occupancy reduces it. It's important to carry out regular maintenance as a dirty, unchanged air filter is one of the main causes of heating and air conditioning problems such as moldy ducts or water damage. To change your air conditioner filter, first locate where it is in your home and remove it. Then hold it up to the light and if you can't see through it, replace it with a new one.
Visit your air conditioner manufacturer's website to find out where you can buy the air filters your system uses or ask your technical expert for the size you need. Changing your air conditioner filter regularly not only helps improve the quality and condition of your home's air but can also save you money over time. To make sure you remember this important task, learn how often you should change your air filter in the first place.
