A Guide to Air Filters

Posted March 24, 2023 by in Lifestyle

There’s no doubt that your HVAC system’s air filters play a crucial role in maintaining indoor air quality and keeping your HVAC system functioning. Essentially, air filters trap dust, dirt, and other airborne particles that can cause damage or reduce efficiency if allowed to accumulate within your HVAC system. The type of air filter you choose will impact its efficiency and longevity, as well as the level of maintenance that your system requires.

However, many homeowners don’t know much about their HVAC system’s filters or how they work. Fortunately, there are resources available to assist you. If you’re in need of some advice, keep reading for a basic guide to air filters.

What should you know when shopping for air filters?

MERV 13 vs HEPA is an important comparison when it comes to air filtration. The MERV rating system was developed in the 1960s to assess how well filters can capture particles from the air, with MERV 13 being one of the highest ratings for residential use. A MERV 13 filter can trap up to 95 percent of airborne particles between 3-10 microns in size, making it good for removing pet dander, pollen, and dust mite debris from your home’s air. MERV 13 filters are more than effective enough for most standard uses and in most homes.

On the other hand, a HEPA filter has been designed specifically as an industrial-grade filter that is capable of trapping 99.97 percent of all airborne particles 0.3 microns or larger in diameter due to its webbed construction made out of ultra-fine fibers which are arranged into pleated paper patterned frame. This makes them ideal for those who suffer from severe allergies or asthma as they will be able to remove even more allergens than the standard MERV 13 filter. Both types offer excellent protection against airborne pollutants but if you need the strongest protection then a HEPA filter is the best choice.

Remember that no matter which air filter you choose, you will need to be proactive about regular maintenance if you want to protect your air quality and keep your HVAC system in good working order. That means the filter should be changed at least once every 90 days and the HVAC unit itself should be inspected annually. Many homeowners opt to change their filters on a monthly basis to ensure optimal performance.

How else can you improve your indoor air quality?

Now that you know more about air filters, let’s discuss some of the things you can do to improve your indoor air quality. For example, you should purchase a high-quality air purifier for your home. An air purifier can remove pollutants and allergens from the air. It can also reduce the spread of germs and viruses. Air purifiers come in a variety of sizes and styles, so do your research to find one that meets your needs. When shopping for an air purifier, be sure to consider the size of your home, the type of pollutants you are trying to remove, and the price.

If you want to get serious about protecting your air quality, then you need to avoid the use of products containing volatile organic compounds (VOCs). When VOCs are present in your home, they can come into contact with your indoor air and cause a range of adverse health effects. Some of the short-term symptoms include eye, nose, and throat irritation, headaches, fatigue, dizziness, and nausea. With long-term exposure, VOCs have been linked to an increased risk of developing cancer and damage to the liver, kidney, and central nervous system.


As you can see, air filters are a fantastic way to ensure that the air in your living spaces is clean and safe. Choosing the right air filter for your home is required for maintaining healthy indoor air quality, as filters are designed to clean the air that circulates throughout your house. Clean indoor air not only ensures a healthier household, but it can also reduce the frequency and severity of allergy and asthma symptoms. You can further protect your home’s air quality by taking steps like buying an air purifier and avoiding products that contain VOCs. Follow this advice and you can breathe easier whenever you spend time at home.
