A guide to finding the best furnace filter for winter

When winter arrives, HVAC systems in commercial buildings work tirelessly to maintain a warm and comfortable environment for workers and customers. The performance of these systems largely depends on a critical component: the furnace filter. Selecting the right one can make all the difference.

This guide is designed for building owners and managers seeking to optimize operations and provide the best experience. Here, we'll explore why furnace filters are essential, the types available, and how to choose the best one for your needs.

Why is the right furnace filter essential in winter?

A quality furnace filter keeps indoor air clean and protects your HVAC system, extending its lifespan and improving efficiency. During winter, when heating systems operate at total capacity, a reliable filter ensures the following:

• Reduced dust and particle buildup.
• Lower operational costs by optimizing airflow.
• Improved indoor air quality is essential in commercial environments.

Types of furnace filters for winter

Pleated filters

They are excellent for capturing small particles like dust, pollen, and mold spores. They also offer a good balance between efficiency and airflow. Most are rated MERV 8 to 13, ideal for residential systems.
Pleated filters are an excellent choice for winter because they help keep the air clean when windows are closed and the heating system is used more frequently.

HEPA filters (high efficiency)

They filter up to 99.97% of particles as small as 0.3 microns, making them ideal for people with allergies or asthma. However, not all HVAC systems are compatible with HEPA filters, as they can restrict airflow. It's best to consult the manufacturer or a professional before installing them.

Activated carbon filters

They remove odors, volatile organic compounds (VOCs), and particles. They are perfect for fresh indoor air during winter, especially when natural ventilation is limited. They are recommended for spaces with pets, smokers, gyms, or areas with strong odors.

Electrostatic filters

These use static electricity to capture particles. They can be a good option when something more efficient than a primary filter is needed but less restrictive than a HEPA filter. They are effective in winter, as they trap fine particles like ash from fireplaces or gas heaters.

Important considerations

• Most residential HVAC systems perform best with MERV 8 to 13 filters. This ensures a good balance between filtration and energy efficiency.
• Avoid using filters with a MERV rating higher than 13 without confirming with the manufacturer, as they can restrict airflow and overwork the system.
• During winter, check the filter every 30 days and replace it at least every 90 days. If you have pets or allergies, consider replacing them more frequently.
• If you need a versatile option, choose pleated filters with a MERV rating of 8 to 13. If air quality is your priority, consult about HEPA filters compatible with your system.

Key considerations for selecting a furnace filter

1. Determine the building's needs: if you have high occupancy, prioritize HEPA or MERV 13+ filters. If odor control is a concern, consider activated carbon options.
2. For a lower budget, pleated filters are an efficient and economical solution.Check HVAC system compatibility: as mentioned, not all systems support high-efficiency filters like HEPA.
3. Consider the environment: opt for filters that capture smog particles or retain dust and pollen.

Keep in mind that using the correct filter not only ensures a cleaner environment but can also:

• Reduce respiratory illnesses among employees.
• Enhance the customer experience with fresh, odor-free spaces.
• Lower costs by consuming less energy, resulting in reduced bills.
