Why do I need to change my air filter?

There are several reasons you should change your air filter on a regular basis. While the recommendation for the frequency you should change your air filter can vary, every 90 days is an approximate estimate. Your location, usage of your HVAC system, whether you have pets or not, age of equipment, and other factors can all contribute to the appropriate frequency of changing your air filter. It doesn’t hurt to change your air filter too often, but there can be consequences of changing it too late. Check with a professional for a personalized recommendation on how often you should change your air filter. In the meantime, if you need some motivation to change your air filter, here are some of the benefits of maintaining a clean HVAC air filter. 

  1. Improve air quality in your home: Air filters have a direct impact on the quality of air entering your home when your HVAC is running. The purpose of the air filter is to clean the air circulating through the HVAC system. A dirty air filter can interfere with the ability of the air filter to do its job. It can also cause trapped grime to be released into your home. With much of our time spent indoors, it’s important to maintain good air quality. Indoor air quality is often worse than outdoor air quality. 
  2. Improve energy efficiency: A clean air filter can help your system operate more efficiently. Dirty air filters can cause the HVAC system to work harder as it tries to push air through your system. The more efficient your HVAC system can run, the more you can save on your utility bill.
  3. Extend the lifespan of your HVAC unit: Maintaining a clean air filter and performing regular maintenance can help your HVAC last longer. Dirty air filters can cause the system to work harder and potentially clog up your HVAC unit. 
  4. Reduce the likelihood of repairs: Repairing your HVAC system can be just as costly as replacing it in some cases. To reduce the likelihood of repairs, perform regular maintenance, including changing your air filter on a regular basis. 
  5. Improve temperature control: Changing your air filter regularly promotes greater efficiency. Your system can work to produce the right amount of hot or cold air and air can pass through easily. This allows you to have more control over maintaining a consistent temperature for your home.

FAQs

With its thicker and more efficient design, a 2-inch air filter outperforms standard filters during residential or commercial use by capturing more airborne particles, including pollen, allergens, and dust. It securely fits into the HVAC slot while preventing air from leaking and ensuring you breathe clean indoor air. At Air Filters Delivered, we make standard and custom 2 inch sizes, which enable you to keep your energy costs down by up to 15% when you regularly change your filter. 

A 2-inch filter provides excellent filtration compared to thinner alternatives. Its deeper construction enhances air quality, minimizing airflow restriction and making your HVAC system operate more efficiently while it consumes less energy. The extended lifespan and convenience of 2 inch filters means it doesn’t need to be changed as often, making them a more affordable and practical solution for your air filtration needs.

For peak efficiency, examine your 2-inch furnace filter every 1 to 3 months, while considering the size of your home or business, whether pets or smokers are present, and the air quality you’re seeking. If you see accumulated dust, have restricted airflow, or your power bill costs have gone up, these are signs you need to swap it out and replace the air filter in your home.

2 inch thick air filters provide better air purification and reduce HVAC system strain to promote energy efficiency.  They prevent airflow blockages caused by the buildup of debris. When a filter gets clogged, your HVAC system has to work harder, leading to more expensive utility bills and using extra energy. It accelerates the wear and tear on system parts. When you switch to a thicker 2 inch filter with durable construction, it supports consistent performance, ensuring your HVAC unit has a longer operational life.  

When purchasing a 2-inch air filter, consider the amount of filtration, durability, and whether it's compatible with your HVAC system. MERV ratings determine how well the filter removes different types of contaminants. Pleated air filters with higher MERV ratings remove more particles than the lower-rated basic fiberglass filter alternatives. Buying the right size and replacing it consistently when you need to dispose of a dirty air filter will ensure your HVAC system operates at maximum efficiency. 

A 2-inch air filter can’t replace a 3-inch filter because it won’t fit right in its designated slot. HVAC systems are made to use specific filter sizes. Thinner filters that aren’t the proper size will create gaps, allowing unfiltered air, dust, and allergens to bypass your system and reducing overall efficiency. When you use the filter size that is recommended for your HVAC system, it will perform properly and ensure its longevity. 

If you’re trying to understand the difference between a MERV vs. MPR vs. FPR Rating, read on for an explanation. MERV ratings are assigned by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, which measures the efficiency of filters used in HVAC systems. The common industry standard of MERV ranks filters from 1 to 20 based on their capacity for capturing different sizes of particulates. Developed by 3M, MPR uses a scale of 300 to 2800 FPR to determine smaller microparticle filtration levels. Exclusively used by Home Depot, FPR simplifies ratings into a 1 to 12 scale to make it easier for consumers when they need to pick out a filter.  MERV ratings are the most widely accepted and used rating system, but MRP and FPR provide other ways to compare filters and their performance.  Our 2 inch filters at Air Filters Delivered are available in custom sizes too, with  various MERV ratings. 

Most 2-inch air filters are disposable and need to be replaced when they get dirty instead of being cleaned and reused. Washable filters are less effective at filtering air than higher-MERV-rated disposable models. You should assess how much upkeep a filter needs, ensure it fits your HVAC system, and confirm it meets the level of air purification you need for your home or business. 

A 2-inch air filter’s depth increases its ability to trap pollen, allergens, and other particles that can trigger allergy and asthma attacks. If you have allergies and upgrade to an air filter with a MERV 13 rating, they are highly effective at removing microscopic contaminants. 2 inch filters can also eliminate VOCS (volatile organic compounds) which if allowed to circulate in your airspace, may irritate your eyes, throat, and nose, and affect your respiratory system in a negative way making it difficult to breathe.
