How to Improve Air Quality in Your Home or Office Building
August 27, 2024
Air filters play a crucial role in maintaining your HVAC system’s efficiency and improving indoor air quality. Regularly changing your air filter not only keeps your air clean but also helps prolong the lifespan of your HVAC system. Let’s explore some of the most common types of air filters and their benefits.
1. Polyester/Fiberglass Filters
Polyester or fiberglass filters are among the most affordable options. They are disposable and designed to filter out large particles like dust and lint. While these filters are cost-effective, they primarily protect your HVAC system from large debris rather than enhancing air quality.
2. Washable Filters
Washable filters can be cleaned and reused for several years, making them an eco-friendly choice. Over time, washable filters can save money and reduce waste, but they require regular maintenance to ensure optimal performance.
3. Pleated Filters
Pleated filters have a larger surface area, allowing them to capture more particles compared to other filters. They improve air quality by trapping smaller particles, making them a popular choice for households.
4. Electrostatic Filters
Electrostatic filters can be either disposable or reusable. They use an electrostatic charge to attract and capture small particles, providing better air quality. These filters are cost-effective and offer flexibility in terms of waste reduction.
5. HEPA Filters
High-Efficiency Particulate Air (HEPA) filters are designed to remove at least 99.97 percent of airborne allergens and pollutants, making them ideal for people with allergies or respiratory issues.
Choosing the Right Filter
When selecting an air filter, it’s important to choose the correct size for your return vent or furnace. Additionally, consider the Minimum Efficiency Reporting Value (MERV) rating, which ranges from 1 to 20. Higher MERV ratings indicate better performance in trapping particles, with most households finding MERV 8 to 13 filters to be ideal for balancing efficiency and air quality.
Regular maintenance and timely replacement of air filters are key to keeping your HVAC system running smoothly and ensuring clean, healthy air in your home. Mountain Peak Air can help you determine the right air filters for your system and even change them for you if you sign up for our Peak Plan!
