What allergens are in the air indoors?

Indoor allergens include dust mites, pet dander, mold spores, and pollen. These allergens collect on soft surfaces, in hidden areas, and can remain suspended in the air, recirculating throughout the home.

Where do indoor allergens typically collect?

Indoor allergens commonly collect in bedding, mattresses, upholstered furniture, carpets, bathrooms, basements, kitchens, and areas with poor ventilation. They can also be tracked in from outside and settle on floors, clothing, and surfaces.

Why do allergy symptoms feel worse indoors or at night?

Indoor allergy symptoms often feel worse because exposure is continuous. Bedrooms in particular combine long exposure time with soft materials that trap allergens, leading to increased symptoms overnight or in the morning.

Where should you start to reduce indoor allergens?

Start in the bedroom, where exposure is highest during sleep. Washing bedding, vacuuming thoroughly, reducing soft surfaces, and adding air purification can quickly improve air quality and reduce allergen exposure.

Can you be allergic to air conditioning?

People are not typically allergic to air conditioning itself, but to the allergens it circulates, such as dust, pollen, pet dander, and mold. Dirty filters and poor maintenance can worsen symptoms.

How can you test for indoor allergens?

Indoor allergens can be tested using at-home screening kits or professional air quality testing. Testing is most useful when the source of symptoms is unclear, or when issues like mold, musty odors, or water damage are present.

What is the best way to remove indoor allergens?

The most effective approach combines four steps: source control, cleaning that captures particles, moisture control, and air filtration. Applying this system room by room helps reduce both surface buildup and airborne allergens.

Do air purifiers help with indoor allergens?

Yes, air purifiers help reduce airborne allergens that remain suspended after cleaning. They are especially effective in bedrooms and high-use areas, providing continuous air cleaning to lower exposure.

How quickly can you reduce indoor allergens?

You can begin reducing indoor allergens within days by focusing on high-impact areas like the bedroom, washing bedding, vacuuming, controlling moisture, and improving air filtration. A structured 7-day plan can deliver noticeable improvements.

Hantavirus Outbreaks: Infection Control Ventilation

The air we breathe provides unseen health risks requiring infection control ventilation

Hantavirus has recently returned to the headlines following reports of a serious outbreak connected to cruise ship travel. The World Health Organization (WHO) reported a cluster of severe respiratory illnesses on a cruise ship on May 2, 2026. As of May 4, WHO reported seven confirmed or suspected cases, including three deaths, with investigations ongoing.¹

The outbreak is a reminder that health risks in cruise ships, schools, hospitality, and multifamily buildings aren’t always visible. The same is true for other shared indoor spaces where people gather. Health risks can also involve the air people breathe. This incident is a stark reminder of the need and value of improving indoor air quality in public spaces.

How Healthy Spaces Is Aiming to Improve Air Quality

SONA Air purifiers work continuously in the background to support cleaner indoor air 24/7.

Healthy Spaces, a PRK Williams Company, is dedicated to improving the air people breathe. We support cleaner air in homes, businesses, and shared public environments.

Healthy Spaces is a leader in the design and construction of healthy homes and indoor spaces. We’ve developed standards focused on creating cleaner, healthier environments. These standards can be applied in residential settings, cruise ships, hospitality, and other high-traffic public spaces. They incorporate advanced air-cleaning technologies as part of a layered indoor air quality strategy.

At the center of this approach is SONA — the Science of Natural Air. The SONA Air Purifier is designed to work continuously in the background. It helps support cleaner indoor air 24/7. In addition, it adds another layer of protection for spaces where people live, work, travel, and gather.

Benefits of a Healthy Space

Reduction of COVID-19 and influenza

Third-party research suggests ionization can help reduce the infectivity of airborne respiratory viruses under controlled test conditions, including SARS-CoV-2 and influenza. In a peer-reviewed PLOS ONE study using a large, room-sized BSL-3 test chamber, researchers reported an 88.3% to 99.98% reduction in viral infectivity after 30 minutes at real-world virus concentrations. These results indicate ionization can be a supplemental indoor air quality tool when used as part of a layered strategy to reduce airborne viral risks.²

Targets airborne particulate matter

Healthy Spaces technology produces ions that interact with airborne particles, including allergens and particulate matter like PM2.5 and PM10. This process can help support the reduction of particles suspended in indoor air as part of an overall air-quality strategy.

Helps reduce unwanted odors without chemical sprays

Healthy Spaces technology helps address unwanted odors by breaking down odor-causing compounds at the source. It does this without relying on toxic chemical sprays or masking agents.

Strengthens your overall IAQ strategy

Healthy Spaces adds another layer to a broader indoor air quality approach through ionization. It is designed to support cleaner indoor air in the spaces where people live, work, travel, and gather.

SUMMARY

Hantavirus outbreaks serve as an important reminder that healthier indoor environments begin with prevention, awareness, and smart building practices. Healthy Spaces can help strengthen a broader indoor air quality strategy. It adds another layer of air treatment in shared spaces.

In today’s world, better indoor air is no longer just a nice-to-have. It is an essential part of responsible building management.
