AC Filters for People with Allergies
Many people are afflicted by allergies, and indoor air quality (IAQ) either makes it easier or more difficult to control symptoms. If your goal is to improve IAQ and limit the existence of allergens in your home, selecting the correct AC filter is essential. Learn which air filter ratings are preferred for people living with allergies and tips for finding11 the right AC filter.
Allergens and Indoor Air Quality
Allergens are materials that trigger allergic reactions in some individuals. Common indoor allergens include:
- Dust mites
- Pet dander
- Mold spores
- Tobacco smoke
- Volatile organic compounds (VOCs)
- Bacteria and viruses
Common outdoor allergens include:
- Pollen
- Ragweed
- Wildfire smoke
- Smog and ozone
These allergens can be in the air or accumulate on surfaces, causing irritation for allergy sufferers when inhaled, ingested or coming in contact with eyes. Keeping clean indoor air is an important part of managing allergy symptoms, and using an effective AC filter to lower the amount of allergens is a key component.
Do Filters Help Reduce Allergy Symptoms?
Traditional AC filters are ill-equipped to reduce allergy symptoms. Most are merely supposed to get rid of dust particles, textile fibers and other large airborne substances from getting into your HVAC system. A higher-end filter is needed to catch32 allergens and prevent them from circulating throughout your home.
The ideal air conditioning system filters for allergies have a high minimum efficiency reporting value, or MERV rating, which denotes37 their effectiveness at capturing small particles on a scale of 1 to 20. For instance, a MERV 8 filter can trap pollen and mold spores, while a MERV 13 filter can also remove very small smoke particles and large bacteria. An allergy AC filter with a high enough MERV rating minimizes airborne allergens for much-needed relief.
Please keep in mind44 that MERV ratings of 17 to 20 describe high-efficiency particulate air (HEPA) filters designed to take out at least 99.97 percent of particles as tiny as 0.3 microns in size. While this makes them highly effective at removing allergens like dust, mold spores, bacteria and viruses from the air, most HEPA filters slow airflow so severely that they are not well-suited for residential situations. Seek advice from51 a professional before getting a HEPA filter to find out if your air conditioning system is compatible.
Are Allergy Filters Worth the Cost?
While allergy air filters for AC units are typically more expensive than standard filters, the rewards usually outweigh the costs for allergy sufferers. After all, spending money on a high-quality AC filter for allergies helps maintain excellent indoor air quality and reduces allergy symptoms, strengthening overall health and well-being. In addition, using a filter with a higher MERV rating can lengthen your HVAC system’s life by helping it stay clean and function correctly. Remember these long-term benefits of allergy filters when determining whether to buy yourself one.
Recommendations for Choosing an AC Filter
Selecting the best air filter is necessary for good IAQ and a reduction in allergy symptoms. Here are some essential tips and methods to help you choose the perfect HVAC system filter for allergies:
- Consider the MERV rating: Choose a filter with a MERV rating suited for your needs. For many allergy sufferers, a filter rated MERV 11 to 13 provides the ideal balance between allergen capture and airflow efficiency.
- Choose the proper filter size: Air filters come in various sizes, so select one that fits your HVAC system precisely. Ill-fitting filters allow allergens to blow right into your HVAC system, undermining the filter’s usefulness. Refer to your HVAC system’s manual or reach out to a professional for help determining the proper filter size.
- Try a pleated electrostatic filter: Pleated filters have more surface area for catching allergens and are typically more effective than flat panel filters. Those that make use of electrostatic characteristics are even better. The electrostatic charge helps these filters attract and trap allergens more efficiently than standard filters with comparable designs and materials.
- Replace your filter regularly: Once you install a filter, remember to change it often for optimal performance. A good strategy is to exchange disposable filters every 30 to 90 days, but check the manufacturer’s instructions for the recommended replacement interval.
- Contact a professional: If you’re unsure about which filter is right for your needs or how to maintain your HVAC system properly, ask a skilled Expert to help you make an informed decision.
