The Importance of Regularly Replacing Your Air Filter

Replacing air filters is essential for maintaining a healthy and comfortable environment in your home or commercial space. Here’s why:

  • Air filters play a crucial role in your central air system by removing harmful pollutants such as pollen, dust, dander, smoke, and bacteria, ensuring these particles don't circulate throughout your indoor spaces.
  • Clean air filters prevent the growth of mold and mildew in your air duct system, which can otherwise lead to health issues.
  • Regularly replacing air filters ensures your HVAC system runs efficiently, reducing strain and preventing damage caused by forcing air through a dirty filter.
  • Additionally, timely filter replacements can help lower energy bills, especially during periods of high usage.
  • AC Filter / Furnace Filter / HVAC Filter / Air Filter -- What's the Difference?

    When it comes to maintaining indoor air quality, you might come across terms like AC filter, furnace filter, HVAC filter, and air filter. Despite the different names, these terms all refer to the same essential component: the filter that cleans the air passing through your heating and cooling system. Whether you call it an AC filter, furnace filter, HVAC filter, or air filter, its primary job is to trap dust, pollen, and other particles, ensuring the air in your home or office is clean and healthy. So, no matter which term you use, you're talking about the same crucial part of your system.

    FAQs

    Air filters function as barriers and keep harmful airborne particles from circulating in your air. They’re an essential part of HVAC systems. They support respiratory health and ensure the air you breathe is clean.  You can prevent potential HVAC system damage and expensive repairs by using an effective air filter and changing it when it's dirty, to ensure your HVAC equipment has a longer lifespan. 

    The type of air quality you need in your house and the workload of your HVAC system should be considered when determining how often to change your air filter. High-efficiency filters usually last longer than standard fiberglass filters, which need to be changed every month. You’ll need to switch out your air filter more often if you have a pet, or have someone living in the home who is a smoker or who has allergies. 

    Choosing the ideal air filter to use in your home depends on your specific needs, including balancing airflow, purification, and energy efficiency. Air filters with higher MERV ratings are better to use when you want to manage pet dander, pollen, and dust. Actuated carbon filters work well in removing odors and VOCs (volatile organic compounds). Using air filters for your home that fit your HVAC system properly will keep clean air circulating in your living space. 

    High-quality air filters are conveniently available online when you need them for high-performance air purification. Air Filters Delivered carries a wide selection of premium air filters with various MERV ratings that are compatible with different HVAC systems. Our easy-to-navigate website makes it simple to find all types of air filters online that offer effective filtration and are priced competitively.  

    Airflow can be restricted when you neglect to change a clogged or dirty air filter, causing your HVAC system to work harder and operate less efficiently.  When you see dust accumulating on surfaces in your home or visible signs of dirt or discoloration, these are signs that your air filter needs to be replaced. If your HVAC system frequently cycles, it's time for air filter replacement. When your allergy symptoms seem to be getting worse, it's an indication you need to replace your filter. Unusual, persistent odors lingering in your airspace may mean your filter change is overdue. If your utility bill unexpectedly increases, change out your filter. Replace your air filter at the recommended time to ensure you have clean air and to keep your HVAC system properly functioning. 

    Using home air filters with the right MERV filters lowers your exposure to common airborne allergens. Microscopic irritants are captured by an air filter with a higher MERV rating, preventing them from settling on interior surfaces and recirculating through your HVAC system. You'll breathe cleaner, healthier air if you use the proper air filter when cooling your home and when you replace it on a consistent basis. 

    When you want to determine the size of the air filter your HVAC system uses, check your existing one for the dimensions printed on its frame. Ask an HVAC professional for assistance or to measure the slot if you don't have the filter you were previously using. The measurements may also be included in your HVAC system manual. Before purchasing a replacement filter, verify the width, height, and thickness to make sure you’re getting the one that fits so your HVAC system will work correctly. 

    Air filters' ability to capture airborne particles, and their effectiveness, are evaluated and measured by MERV ratings (Minimum Efficiency Rating Value) on a scale from 1 to 16. MERV filters with higher ratings trap finer particles, but might restrict air flow and affect HVAC performance. Your HVAC system will function better if you choose an air filter in the appropriate size with a MERV rating that balances air flow and filtration.

    Washable and reusable air filters are a cost-effective and environmentally responsible alternative to disposable air filters. They can be easily cleaned and reused instead of replacing them, reducing waste and saving money over time. Although convenient, when you need advanced air purification, they may not be as effective in trapping microscopic contaminants as disposable filters with higher-MERV ratings. 

    Specific types of air filters are designed to reduce unpleasant smells. To neutralize pet and cooking odors, smoke, and smells from other sources, use an activated carbon filter so the air in your home smells fresh. Regularly maintained HVAC systems that use clean air filters circulate cleaner air and prevent odors from lingering in your home.Â
