This guide will provide step-by-step instructions on how to change your house’s air filter, empowering you to create a healthier and more comfortable living space.
Understanding Air Filters
Air filters come in various types and sizes. The most common types are:
- Fiberglass: Made from synthetic fibers, they are affordable and effective at trapping larger particles.
- Pleated: These filters have a larger surface area, allowing for better filtration and longer lifespans.
- HEPA (High-Efficiency Particulate Air): HEPA filters are the most efficient at removing airborne particles, including allergens and bacteria.
Frequency of Air Filter Replacement
The frequency of air filter replacement depends on several factors, including:
- Type of air filter
- Household activity level
- Presence of pets
- Outdoor air quality
As a general rule, it’s recommended to change your air filter every 1-3 months. If you have pets or live in a dusty area, you may need to change it more frequently.
