5 Common Fall Allergens (and How to Address Them)

For many people, all of the changing leaves and pumpkin-spice foods are a pleasant change of pace. For the rest, it’s a sign of one awful eventuality: allergies.

Fall allergies have a way of knocking people out cold, disrupting their lives for days or weeks at a time. It’s easy to feel helpless when fall allergies start to flare up, but you do have some options.

Today, we’ll go over five of the most common fall allergens and what you can do about them.

Mold and Mildew

Nobody likes to think that they could be breathing in mold or mildew. Even if your home is spotless and there’s nothing wrong with your HVAC system, mold spores are still a problem your body must contend with.

One effective solution is to install a UV light filter in your HVAC system. The ultraviolet light will kill mold spores as they circulate through your system, significantly reducing (if not entirely eliminating) your risk of exposure.

Dust Mites

Dust mites — they are everywhere. They love to feed on human skin flakes, and there are probably a couple hundred thousand of them in your mattress. But don’t go throwing your bed onto a street corner just yet. Dust mites need warmer, more humid climates to survive.

This means a quick and easy solution can be found in whole house dehumidifiers. By controlling the humidity in your home, to make sure that humidity levels are below 50%, dust mites will have a much harder time living in your home.

Pet Dander

Pet allergies are very common, and they can get especially troublesome in the fall. If you have pets, it’s important that you keep your space as clean as you can. You will also want to make sure you have a decent air filter installed in your HVAC system with a high enough MERV rating to block out pet dander.


Pollen is infamous for its sweeping and debilitating effects on those who are allergic to it. The worst thing about pollen is that it’s just about everywhere. When you leave your home and breathe it in, you might feel that something is wrong right away.

When it comes to fighting pollen allergies, your best bet is to stay indoors as much as you can. After that, you need an air filter that’s strong enough to block pollen.

While most basic filters can do this to some degree, you might want to consider higher MERV rating filters to block out bacteria and airborne viruses, too!


This single plant is so potent and far-reaching that it needs its own category. While the root issue is pollen, ragweed gets special notice for its abundance all over the country.

To make matters worse, ragweed’s pollen is so light that it can travel for hundreds of miles before settling. That means you could be sneezing because of ragweed from another state!

The best thing you can do to fight against ragweed is to install a strong air filter in your HVAC system and make sure to change it regularly.
