Why Allergy Symptoms Continue Indoors in Spring

If your allergy symptoms don’t improve indoors, your attic could be part of the problem. Many homes allow outside air—and the pollutants it carries—to enter from above, where gaps and leaks often go unnoticed.

How Allergens Build Up Indoors

Homes are not airtight. Air moves in and out constantly.

Common entry points include:

• Gaps around windows and doors
• Attic penetrations and recessed lighting
• Crawl spaces and basements
• Leaky ductwork

As outdoor air enters, it carries pollen and other irritants. Over time, these particles settle and continue circulating throughout the home.

Why Air Sealing Is Important

Closing gaps and sealing air leaks in a home has many benefits. The process can:

• Limit pollen and dust infiltration
• Reduce moisture that can contribute to mold
• Improve the effectiveness of HVAC and filtration systems

Even after sealing major entry points, some airborne particles remain—this is where air purification makes a difference.

Why Allergy Sufferers Should Consider the Aspen Air Purifier

The Aspen Air Purifier is designed to remove a range of common indoor pollutants using a three-stage filtration system:

• Allergy filter captures larger particles such as pollen, pet dander, mold, and dust
• Activated carbon filter reduces odors and gases, including VOCs, smoke, and household chemicals
• Microparticle HEPA filter removes 99.97% of particles down to 0.1 microns, including fine particulates like smoke, bacteria, and smog

The unit is built for continuous use and can cover up to 1,500 square feet. Filters slide out for easy replacement, and its portability allows it to be used in different areas of the home.

Used alongside air sealing, it helps lower the overall concentration of airborne allergens indoors.

The Aspen Air Purifier uses mechanical filtration only. It does not rely on ionizers, ozone generators, or UV-based systems, so it does not introduce ozone or other byproducts into the air. This allows it to operate continuously without adding anything unwanted to the indoor environment.

It is also designed with efficiency in mind. The unit uses an EC fan motor that adjusts output as needed and consumes significantly less electricity than a standard AC fan. Because lower fan speeds are most often used, the energy savings are noticeable in everyday operation.

For homeowners considering an Aspen system, working with Attic Systems helps ensure the unit is properly sized and placed within the home. Setup and airflow matter, and correct installation plays a role in overall performance.
