When Should I Replace My Home Air Filter?
Having a clean air filter in your home is essential for maintaining good air quality. Over time, however, the filter can become clogged with dirt and debris, reducing its effectiveness. To ensure your home's air remains healthy, it's important to know when it's time to change your air filter.
Signs You Need to Change Your Air Filter
There are several signs that indicate it may be time to replace your air filter:
- Your current filter looks dirty or clogged.
- You can smell odors coming from the vents.
- Your energy bills have increased.
- You have noticed an increase in allergy symptoms.
If you notice any of these signs, it is likely that you need to change your air filter. The frequency with which you should do so will depend on the type of filter you have and the level of airborne particles in your home.
Types of Air Filters
There are several different types of filters available for homes. The most common types are disposable fiberglass filters, pleated filters, and electronic filters. Each type has its own advantages and disadvantages:
- Disposable Fiberglass Filters: These are the most affordable type of air filter and they are easy to install. However, they need to be changed more often than other types of filters because they quickly become clogged with dust and debris. They are best suited for homes with low levels of airborne particles.
- Pleated Filters: Pleated filters cost more than disposable fiberglass filters but last longer. They also capture smaller particles than disposable fiberglass filters making them a good choice for homes with pets or allergies. However, they require more frequent cleaning than other types of filters.
- Electronic Filters: Electronic filters use electricity to capture particles from the air. They are the most expensive type of filter but require minimal maintenance and can capture even the smallest particles making them a good choice for homes with severe allergies or asthma.
How Often Should You Change Your Air Filter?
The frequency at which you need to change your air filter will depend on several factors including the type of filter you have as well as the amount of airborne particles in your home. Generally speaking, disposable fiberglass filters should be changed every 30 days while pleated ones should be changed every 90 days. Electronic ones should be cleaned every 6 months. It is also important to inspect your air filter regularly and replace it when necessary if any signs appear that indicate it needs changing, such as a buildup of dirt or an increase in allergy symptoms.
