How To Choose the Right Air Filter for Your Home




Having clean and fresh indoor air quality is essential to maintain the health and well-being of you and your family.

Having clean and fresh indoor air quality is essential to maintain the health and well-being of you and your family. One way to achieve this is by choosing the right air filter. However, with so many options on your plate, narrowing your choices can feel like an overwhelming task. 



We’re here to guide you through the process of selecting the perfect air filter for your home. In this comprehensive article, we’ll share our expertise on choosing the right air filter for your home, while considering various factors and answering some common questions.


Why Choosing the Right Air Filter Matters

Choosing air filters for your house is a crucial decision that has a significant impact on your indoor air quality, the efficiency of your HVAC system, and the overall comfort and health of your household.


Improved Indoor Air Quality (IAQ)


An air filter can improve indoor air quality because it has the following characteristics:


  • Particle Removal: Air filters are designed to capture and trap particles such as dust, pollen, pet dander, mold spores, and even airborne bacteria and viruses. The filtration process results in cleaner air that is easier to breathe and healthier for everyone in your household.

  • Allergen Control: For individuals with allergies or asthma, airborne allergens like pollen and pet dander can trigger symptoms. A high-quality air filter can significantly reduce these allergens, providing relief to those who suffer from respiratory conditions.


Enhanced HVAC System Efficiency


Your HVAC system consists of various components that work together to regulate temperature and airflow in your home. When the air filter is clogged or inefficient, it can have negative effects on your HVAC system, such as:


  • Reduced Airflow: A dirty or clogged filter restricts air flow through the system. This reduced airflow makes your HVAC system work harder to maintain the desired temperature, leading to decreased efficiency and higher energy bills.


  • Strain on Components: The added strain on HVAC components, such as the blower motor and compressor, can lead to premature wear and tear. An improper or old air filter can result in costly repairs and a shorter overall lifespan for your system.


When you invest in the right air filter, you can enhance your HVAC system’s efficiency and minimize potential problems.


Protection for Your Home


Air filters also help protect your home’s HVAC system itself. They prevent dust and debris from accumulating on sensitive components like coils and motors. This feature not only extends the lifespan of your HVAC equipment but also reduces the likelihood of breakdowns and the need for costly repairs.


Energy Efficiency and Cost Savings


When your HVAC system doesn’t have to work as hard to maintain your desired temperature, it consumes less energy. You’ll see lower energy bills and a reduced environmental impact. Over time, the cost savings from improved energy efficiency can more than offset the initial investment in a quality air filter.


Reduced Cleaning and Maintenance


Because efficient air filters capture airborne particles before they settle on surfaces, you won’t have to do as much dusting, vacuuming, and overall cleaning. 


Peace of Mind


Last but not least, knowing that you have a high-quality air filter in place can provide peace of mind that you’re taking care of your family’s health. 



Now that you know the benefits of an air filter, what factors should you consider when choosing an air filter and what is the best type of air filter for your home? 


Step 1: Understand Filter Types


There are several types of air filters to choose from, each with unique features and filtration capabilities.


Fiberglass Filters


Fiberglass filters are the most basic and cost-effective option. They consist of layered fiberglass fibers and are designed to capture larger particles such as dust and lint. While they are suitable for protecting your HVAC system, they may not be as effective at removing smaller allergens and pollutants. Fiberglass filters are often used in homes without specific air quality concerns.


Pleated Filters


Another option is pleated filters. These offer better filtration than fiberglass filters because they have a larger surface area due to their folded design. While they are slightly more expensive than fiberglass filters, pleated filters can capture smaller particles more effectively. 


HEPA Filters


High-efficiency particulate air (HEPA) filters are the gold standard for air filtration. They can capture up to 99.97% of particles as small as 0.3 microns in size, including pollen, dust mites, pet dander, and even some bacteria and viruses. HEPA filters are highly effective at improving indoor air quality and are often recommended for households with allergy or asthma sufferers.


Step 2: Understand MERV Ratings


Another crucial difference between air filters is their MERV ratings. This rating system indicates a filter’s efficiency in capturing particles — the higher the MERV rating, the better the filtration.



However, it’s essential to balance filtration with airflow. Too high a MERV rating can strain your HVAC system, leading to decreased efficiency and increased energy consumption. For most households, a MERV rating between 8 and 13 strikes a good balance between filtration and airflow.


Step 3: Determine Your Needs


Now that you know about filter types and MERV ratings, it’s time to choose a filter. Consider your specific needs and circumstances by asking yourself the following questions:


  • Do you or your family members have allergies or respiratory issues? If so, a HEPA filter or filter with a high MERV rating will be beneficial to capture allergens effectively.


  • Do you have pets? Pet owners should choose filters designed to capture pet dander and hair effectively.


  • Is your home located in an area with high outdoor pollution levels? If so, a filter with a higher MERV rating can help protect your indoor air quality by capturing more pollutants from outside.


Step 4: Check Filter Size


Proper sizing is crucial for the effectiveness of your air filter. To find the right size, refer to your HVAC system’s manual or check the current filter for size specifications. Common sizes include 16×20 inches, 20×25 inches, and 24×30 inches. Remember that using the wrong size filter can lead to air leaks and reduced filtration, so it’s essential to get this step right.


Step 5: Consider Filter Thickness


Filters come in different thicknesses, typically 1 inch or 2 inches. Thicker filters can capture more particles and tend to last longer before needing replacement. However, make sure your HVAC system can accommodate the chosen thickness. If you’re unsure, consult your system’s manual or an HVAC professional.


Step 6: Evaluate Filter Material


The material of the filter also matters. While fiberglass filters are economical, pleated filters offer better filtration, and HEPA filters provide the highest level of purification. Select the filter material that aligns with your specific needs and budget.


Step 7: Regular Maintenance


Once you’ve chosen the right air filter, it’s essential to maintain it properly to ensure optimal performance. Here are some key maintenance tips:


  • Regular Inspection: Check your air filter regularly, typically every one to three months, and inspect it for dirt and clogs. Dirty filters can reduce airflow and strain your HVAC system.

  • Scheduled Replacement: Follow the manufacturer’s recommendations for filter replacement. Replace your filter promptly when it becomes dirty or clogged to maintain good indoor air quality and HVAC efficiency.

  • Professional Inspection: To ensure your system operates at its best, consider scheduling professional HVAC maintenance, including filter inspection and replacement, from a reliable service provider like Viking Heat and Air Conditioning.


Final Words


Choosing the right air filter for your home is a critical decision that can significantly impact your indoor air quality and HVAC system efficiency. By considering factors such as filter type, size, MERV rating, thickness, and material, you can make an informed choice that ensures clean and healthy air for you and your family. 


Plus, regular maintenance and replacement are equally important to keep your HVAC system operating at its best.
