High Efficiency Air Filters

What Are High Efficiency Air Filters?

High efficiency air filters are designed to trap much smaller particles than standard filters. While typical filters might catch large dust and debris, high efficiency filters use advanced materials and tighter weaves to capture microscopic pollutants including:



• Dust mites
  
• Pollen
  
• Mold spores
  
• Pet dander
  
• Smoke particles
  
• Bacteria and viruses (to some extent)
  
  

These filters are rated by a system called MERV (Minimum Efficiency Reporting Value), which measures how well a filter traps particles. The higher the MERV rating, the more effective the filter is at cleaning the air.

Benefits of High Efficiency Air Filters

1. Improve Indoor Air Quality

If you or your family suffer from allergies, asthma, or other respiratory issues, a high efficiency filter can make your home a healthier place to breathe. By reducing airborne irritants, these filters help relieve symptoms and reduce exposure to pollutants.

2. Protect Your HVAC System

Particles like dust and debris can clog up your furnace, air conditioner, or heat pump, causing it to work harder and wear out faster. High efficiency filters help keep your system clean, improving performance and reducing the need for costly repairs.

3. Save Energy and Money

A cleaner HVAC system runs more efficiently, meaning it uses less energy to heat or cool your home. This translates to lower utility bills and a smaller carbon footprint.



4. Reduce Odors and Smoke

High efficiency filters can also trap some smoke particles and odors, improving the overall smell inside your home.

Choosing the Right High Efficiency Air Filter

Not all filters are created equal. When choosing a high efficiency air filter, consider:

• MERV Rating: Filters typically range from MERV 1 to MERV 16. Residential filters usually fall between MERV 8 and MERV 13. Higher ratings trap smaller particles but may reduce airflow if your HVAC system isn’t designed for them. We can help you pick the best option for your system.
  
  
• Filter Type: Common types include fiberglass, pleated filters, and HEPA filters. Pleated filters are popular for residential use because they provide good filtration and airflow. HEPA filters are the most effective but usually require special systems.
  
  
• Size and Fit: It’s important to get the right size filter for your HVAC unit to ensure a proper seal and efficient filtration.

When to Replace Your Air Filter

How often you should replace your filter depends on several factors:

• The type of filter you use
  
• How often your HVAC system runs
  
• Whether you have pets or smokers in the home
  
• The presence of allergy sufferers or respiratory conditions
  
  

Generally, high efficiency filters should be replaced every 3 months, but some may last up to 6 months. Regular replacement is essential to keep your system working well and your air clean.
