Why Are Air Filters Important?
Air filters trap dust, dirt, and pollen. They stop these particles from entering your house. Clean air helps you breathe better. It also keeps your heating and cooling system working well.
If the filter is dirty, it blocks air flow. This makes your system work harder. It can also cause higher energy bills. Dirty filters can make your home dusty and unhealthy.

Types of Air Filters
There are different kinds of air filters. Each type lasts a different time. Here are the common types:
- Fiberglass filters: These are cheap and simple. They usually last 30 days.
- Pleated filters: These are better at catching dirt. They last about 90 days.
- High-efficiency filters: These catch very small particles. They may last 6 months.
How Often to Change Air Filters?
The answer depends on many things. Here are the main factors:
1. Type Of Filter
As said, fiberglass filters need change every month. Pleated filters last longer, about 3 months. High-efficiency filters can last 6 months or more. Always check the package instructions.
2. Use Of Heating Or Cooling System
If you use your air conditioner or heater a lot, change filters more often. During summer or winter, filters get dirty faster. If your system runs all day, check filters every month.
3. Number Of People In The Home
More people mean more dust and dirt inside. If many people live in your house, change filters every 1 to 2 months. Fewer people can wait longer before changing.
4. Pets In The House
Pets shed hair and dander. These can clog filters fast. If you have pets, change your air filter every 1 to 2 months. This keeps your air clean and fresh.
5. Allergies Or Respiratory Problems
If someone has allergies or asthma, use high-quality filters. Change them every 1 to 2 months. Clean air helps reduce allergy symptoms.
6. Location And Air Quality
If you live in a dusty or polluted area, filters get dirty faster. You may need to change filters every 30 to 60 days. In cleaner areas, filters can last longer.
