If you suffer from seasonal allergies, you know the summer months can be especially difficult. You’re probably really interested to find out about the best air conditioner for allergy sufferers or to learn that AC helps with allergies, to begin with! All the pollen, dust, and other airborne allergens can make it hard to breathe and can make it difficult to enjoy the warm weather without ongoing allergic reactions. An air conditioner can purify the air and help keep your allergies at bay.

Indoor Air Quality

The reason air conditioners are helpful for allergy sufferers is that they clean the air and keep fresh air circulating throughout the home. They essentially work like air purifiers to some degree. Poor air quality in your home will make allergy symptoms worse. Maintaining good air quality can help reduce allergy symptoms from allergens like dust mites, pet dander, pollen, and mold spores that can all become airborne, increasing the risk of allergy attacks. Poor air circulation can also cause airborne particles to remain in an enclosed space, making allergy symptoms worse.

An air conditioner can help reduce these risks by filtering out allergens and providing better air circulation. Air conditioners use air filters to capture and remove allergens from the air. The air filters in air conditioners are designed to capture small particles and effectively remove allergens from the air. On top of filtering allergens, air conditioners also help to control the humidity levels of your home. High humidity can cause mold and mildew growth, which is a huge trigger for many allergy sufferers.

The Best Air Conditioner for Allergy Sufferers

There really isn’t a best air conditioner for allergy sufferers, but don’t think we tricked you into reading this blog post! Most HVAC and AC units do the same to improve your air quality, provided they are in good working order. They keep cool, filtered air circulating through the home, and they keep humidity levels down, as we discussed earlier. It’s the AC maintenance and the air filter in your AC that really make the difference in allergens in your home.

There is, however, better air quality with HVAC or whole home AC units vs portable AC units or window AC units. This is because a whole home system circulates all the air, leaves no stagnant areas, and has a better air filtration system. But if we’re talking about a type of HVAC system, no model would do a better job than another.

A good air filter, which you can read more about here, and regular AC maintenance will ensure that your AC can continue to keep your indoor air quality allergen-free.

Tips for Optimal Indoor Air Quality

These tips will not only help your indoor air quality during allergy season and prevent the worsening of respiratory issues, but they will also extend the life of your HVAC unit and may lower your electricity bills.

1. Replace your air filter regularly

By replacing your air conditioner’s filter regularly, you will ensure that your air quality remains high. A dirty air filter will pollute the air in your home. Check your filter at least every 30 days if you have allergies to indoor allergens. You may not need to replace it that often, but it’s a good idea to take a look in case you could benefit from changing a dirty filter and reducing the number of airborne pollutants and allergens that are circulating in your home.

2. Get regular HVAC maintenance

AC maintenance should be done on a regular basis for your whole HVAC system, including air ducts. Clean filters aren’t the only determinant of air quality. Your cooling system has several other parts that should be cleaned regularly, like the coils and condensate drains. Maintenance of a home’s air conditioner goes a long way toward creating healthy indoor air quality.

3. Install an air purification system

A UV light air purification system can help reduce allergens, bacteria, mold, and other contaminants in the air. It kills those microscopic particles in the air that contribute to airborne allergies and illnesses, reduces odors, and improves overall air quality, which can be beneficial for seasonal allergy sufferers and people with asthma.


No matter which AC unit you have, it’s a clean air conditioner that makes all the difference.
