Air Filters And Your Health: A Closer Look

Air Filters And Your Health: A Closer Look

In our previous post, we took a look at popular HVAC air filter types and frequently asked questions about industry nomenclature like the MERV rating system, in addition to discussing the history air filters. It’s fascinating to realize how far we’ve come with our technology in so little time. As a reminder, the MERV rating system refers to the Minimum Efficiency Reporting Value, which essentially judges the quality of the purification of air that occurs. The higher the number, the better.

Before we move onto today’s post, which is about what air filters can do for ailments like asthma, allergies, and even viruses, we would like to remind you about some of the qualities that Brookaire has to offer in the world of replacement air filters and HVAC parts online.

Now that we’ve reminded you a bit about why so many people consider Brookaire the answer to the question “where to buy air filters”, let’s move onto today’s topic at hand. If you have been wondering about air filters and your health, or the health of a family member, read on, because we are going to hit you with some practical facts that will hopefully lead you to making the right decision for your home.

Health Benefits

At times, it can be difficult to sort through the various marketing claims that consumers are inundated with every day for a range of products and industries. Air filtration, at times, is no different as a vertical. Some air filtration manufacturers make promises that, to put it kindly, are difficult to keep. But rather than focus on individual competitors who write checks with their mouths that their execution can’t cash, we thought we would do our best to educate our readers, so that they can judge for themselves.

EPA Recommendations

To start with some foundational principles, let’s see what the Environmental Protection Agency has to say about air filtration and indoor air pollution. They describe three essential elements to reducing indoor air pollution, which are source control, improved ventilation, and air cleaners.

  • Source Control – An easy-to-understand example of source control is second hand smoke, and letting it into your home. Second hand smoke can cause lung cancer, major health problems, and asthma. Second hand smoke is just one example of source control, however. Others include radon, mold, mildew, cockroaches, and dust mites. A solution for the latter three examples listed above is to keep your house more dry than you normally would. Those source control issues thrive in humid environments. Pests should be eliminated with non-chemical methods, rather than chemical sprays, if at all possible.
  • Ventilation – Even if there isn’t much second hand smoke around, ventilation can be a serious issue if there isn’t enough circulation getting through. Most of these tips are pretty obvious, like opening your window to get air flow moving.
  • Air Purifiers – When you have effective source control and appropriate ventilation, you still need to take additional steps to optimize your health in your living area. Air filters do a job that people simply can’t do. The efficacy of air filters are judged on their capacity to eliminate pollution from the air, and the amount of air that can pass through the air filter. Essentially, that means quality and quantity. That “quality” is usually measured in terms of a percentage, while the quantity is talked about in terms of cubic feet per minute.


Air purifiers help people with asthmatic symptoms, more often than not. It’s not a guarantee that each air filter will do the trick, which isn’t widely known. Consumers who are looking to shop air filters to solve asthma problems need to do a significant amount of research. The fact is, the American Lung Association and the EPA have both done research to show that all air purifiers are not created equally, especially when it comes to solving asthma.

However, that doesn’t mean we should just give up because it is difficult. According to The New England Journal of Medicine, in a study of inner-city children who have atopic asthma, “an individualized, home-based, comprehensive environmental intervention decreases exposure to indoor allergens, including cockroach and dust-mite allergens, resulting in reduced asthma-associated morbidity.” Thus, air filters can certainly help. In a future article, we will take a look at what you should look for when you are shopping for an air filter that will help tackle asthmatic issues.


In the same way, air filtration systems can have a significant impact when it comes to allergies, but it’s not as easy as buying the first air filtration system that you find in order to solve all of your allergies. According to the Asthma and Allergy Foundation of America, indoor triggers for allergic reactions include insect infestation, cigarette smoke, pet dander, pet hair, mildew, Volatile Organic Compounds (VOCs), and mold.


We’ve already talked about some of the solutions that the EPA has recommended. Some of them don’t even involve investing in an air filtration system. But if you do decide to take that important additional step, you have options. Choose from HEPA filters (which we have in stock), Electrostatic Filters, Hybrid Filters, and Ozone Generators. For the latter category, we want to let you know that Ozone Generators are not recommended because they add too much ozone to the environment. So they might do the job in eliminating certain toxins from the air, you are essentially cutting off your nose to spite your face because a surplus of ozone can cause further breathing issues.
