How Optimum Performance of Your HVAC System Can Help Reduce Asthma and Allergies



Due to the reduction of allergens and improvement in indoor air quality, HVAC systems have a greater impact on the alleviation of asthma and allergy symptoms than you may expect.

The good news is that there are many simple alternatives available if you want to improve your HVAC system to reduce asthma and allergies.

Keep Common Indoor Allergens out of the House

Indoor air pollution can be caused by a variety of factors and causes. Pet dander, mold, dust mites, pollen, and cockroach droppings are some of the most frequent allergens found in the house, as are dust mite droppings.

However, even though your HVAC system’s air filters are meant to collect the bulk of these allergens when they become airborne, they can still have an impact on you, leading you to have allergic responses or asthma attacks.

What’s more, your HVAC system may be a breeding ground for mildew and mold, which can be released into your interior environment when the system is turned on and off. Therefore, regular maintenance is essential, especially for those who suffer from asthma or allergies.

Start with a Filter

Because the air filter is such an effective element in the reduction of indoor allergens, you should invest in a high-quality filter that is capable of catching even the smallest particles.


The efficacy of an air filter is determined by its MERV rating, which stands for minimal efficiency recording value. One to twenty are assigned to each MERV rating, with the highest number denoting the most effective amount of filtration.

Selecting high-efficiency air filters that can assist reduce allergy triggers is essential when purchasing air filters. The majority of high-efficiency filters have a rating between 14 and 16.

Although these filters are effective at removing microscopic particles, they are not as effective as HEPA filters, which have ratings ranging from 17 to 20.

On the other hand, unless the system has been modified or specifically intended to incorporate HEPA filters, HEPA filters are normally not advised for centralized HVAC systems.

This is due to the fact that the better the effectiveness of the air filter, the greater the strain placed on the HVAC system. To ensure that you are using the correct filter for your system, consult with your HVAC specialist.

Air purifiers fill in the gaps left by HVAC systems

A HEPA filter on an air purifier is the most effective way to trap allergens that your HVAC system cannot remove on its own.

While centralized HVAC systems work best with medium to high-efficiency air filters, adding an air purifier with a HEPA filter is the smartest option for trapping those allergens that your HVAC system cannot remove on its own.


Whole-house air purifiers are especially beneficial for people who suffer from severe asthma or allergies since they improve the air quality across the whole home, making it easier for everyone in the family to breathe.

In this way, you can alleviate symptoms of asthma and allergies.
