American Marconi Wireless News - Kronos Advanced Technologies (OTC:KNOS) FDA-Cleared Air Purifiers Offer Critical Indoor-Air Protection as Canadian Wildfire Smoke Degrades U.S. Air Quality; Significant Discounts Offered to New Customers

PARKERSBURG, WV / ACCESS Newswire / July 24, 2026 / Kronos Advanced Technologies, Inc. (OTC PINK:KNOS) ("Kronos" or the "Company"), an innovator in high-voltage air movement, filtration and air-disinfection technologies, today urged consumers, schools, healthcare providers and businesses to take immediate steps to improve indoor air quality as smoke from Canadian wildfires continues to affect communities across broad areas of the United States.

To help make cleaner indoor air more accessible during the current smoke emergency, Kronos is offering significant discounts to new customers on qualifying FDA-cleared air purifiers and related products. The Company is also making flexible payment options and expedited shipping available where possible.

Canadian Wildfire Smoke Creates Widespread Air-Quality Concerns

Large wildfire complexes burning across Canada have transported dense smoke plumes into the United States, contributing to elevated concentrations of fine-particle pollution in portions of the Midwest, Northeast and Mid-Atlantic. State and federal agencies have issued air-quality alerts in affected areas, with some communities experiencing conditions classified as unhealthy or hazardous.

NASA Satellite Imagery Highlights the Massive Scale of the Smoke Plume

The extraordinary scale of the Canadian wildfire smoke has also been documented by NASA. Using imagery from NASA's Terra satellite and the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument, NASA scientists have captured striking images showing a massive river of smoke stretching across much of North America. Satellite observations from July 2026 show smoke extending from western Canada across the Great Lakes region and reaching as far as the U.S. East Coast, demonstrating that wildfire smoke can travel thousands of miles while significantly degrading air quality far from the fires themselves.

NASA's Earth Observatory notes that satellite monitoring has become an essential tool for tracking wildfire smoke movement, helping scientists, emergency managers and public health officials forecast where smoke will travel and identify communities that may experience deteriorating air quality. These observations reinforce recommendations from health authorities that residents in affected regions should remain informed about local air quality conditions and take appropriate steps to reduce indoor exposure to harmful fine particulate matter (PM2.5).

In mid-July, Michigan environmental officials issued statewide alerts for elevated fine-particle pollution caused by Canadian wildfire smoke, while Connecticut authorities forecast elevated particulate levels across the state. Federal officials have advised residents to use the EPA's AirNow Fire and Smoke Map because smoke conditions and local air quality can change rapidly.

Wildfire smoke contains a complex mixture of gases and microscopic particles. Of particular concern is PM2.5, particulate matter measuring 2.5 micrometers or less in diameter. Because these particles are small enough to travel deep into the lungs, exposure can aggravate respiratory and cardiovascular conditions and may cause coughing, throat and eye irritation, wheezing, chest discomfort, headaches and shortness of breath.

Children, older adults, pregnant individuals, outdoor workers and people with asthma, chronic obstructive pulmonary disease, diabetes or heart disease may face heightened risks from smoke exposure.

The current conditions recall the severe Canadian wildfire-smoke event of June 2023, when New York City and other major metropolitan areas experienced extraordinary pollution levels and widespread disruption. The recurrence of major cross-border smoke events underscores the importance of preparing homes, schools, medical offices and workplaces for periods when outdoor air becomes unsafe.

Government Agencies Recommend Cleaner Indoor-Air Environments

The U.S. Environmental Protection Agency and public-health agencies recommend that residents in smoke-affected areas monitor local Air Quality Index readings, reduce outdoor activity when pollution levels rise, keep windows and doors closed and operate properly selected indoor air-cleaning equipment.

AirNow's AQI scale categorizes readings above 100 as unhealthy for at least some members of the public, readings above 150 as unhealthy for everyone, readings above 200 as very unhealthy and readings above 300 as hazardous. Residents should consult AirNow.gov or the AirNow mobile application for current local conditions.

Additional precautions may include:

• Creating a designated clean-air room inside the home.

• Running an effective air purifier continuously in occupied rooms.

• Setting central HVAC systems to recirculate indoor air where appropriate.

• Avoiding activities that generate additional indoor particles, such as smoking, burning candles or using fireplaces.

• Limiting strenuous outdoor activity during elevated AQI conditions.

• Wearing a properly fitted particulate respirator when outdoor exposure cannot be avoided.

Kronos Technology Designed to Capture and Neutralize Airborne Contaminants

Kronos air purifiers use patented high-voltage-field electrostatic technology to move, capture and neutralize airborne contaminants without relying on conventional disposable HEPA filters.

The Company's technology has demonstrated removal efficiencies of up to 99.98% for tested airborne pollutants, including smoke particles, allergens, bacteria and other airborne contaminants. Unlike many conventional air purifiers that require recurring filter replacement, qualifying Kronos systems use washable or reusable collection components, helping reduce ongoing maintenance costs and filter waste.

Kronos' FDA-cleared air-purification models are classified as Class II medical devices. The Company's Model 5 is designed for larger residential and professional environments and is marketed for spaces of up to approximately 1,400 square feet, subject to room configuration, airflow and operating conditions. A second Kronos model received FDA clearance in 2024, expanding the Company's portfolio of air-purification products intended for use in homes, healthcare settings and other occupied indoor environments.

Key attributes of Kronos air-purification technology include:

• Patented high-voltage electrostatic collection and air-disinfection technology.

• FDA-cleared models for indoor air-purification applications.

• Capture of ultrafine airborne particles, including smoke-related particulate matter.

• Quiet operation suitable for bedrooms, classrooms, waiting rooms and offices.

• Energy-efficient air movement without conventional fan-dependent architecture in applicable models.

• Reusable collection elements that reduce dependence on disposable replacement filters.

• Low-pressure airflow designed to circulate and clean indoor air continuously.

• Products suitable for residential, educational, professional and small-business environments.

Actual performance may vary according to room size, ceiling height, placement, air-exchange rate, pollutant concentration, operating speed and other environmental conditions.

Company Responds to an Increasingly Common Public-Health Challenge

"As wildfire smoke once again moves across the border and creates unhealthy air conditions in American communities, access to effective indoor air purification becomes a health and preparedness priority," said Dr. Greg Rubin, Chief Executive Officer of Kronos Advanced Technologies.

"Kronos technology was developed to remove extremely small airborne contaminants while eliminating the cost and waste associated with repeatedly purchasing conventional filters. We want to help families, schools, medical practices and businesses create cleaner indoor environments during this difficult period, which is why we are making substantial discounts available to qualifying new customers."

Kronos has previously supported public awareness during wildfire-smoke emergencies. In June 2023, the Company issued a public statement regarding the use of its FDA-cleared air purifiers as smoke from Canadian wildfires affected the northeastern United States. The Company also addressed increased air-purifier demand during the January 2025 California wildfires.

Cross-Border Wildfire Conditions Draw National Attention

The widespread movement of smoke across the U.S.-Canada border has also drawn attention from federal and provincial officials. President Donald Trump recently criticized Canada's wildfire and forest-management practices and discussed the economic costs of Canadian smoke entering the United States.

Separately, the Trump administration announced new tariffs on selected Canadian products in connection with broader trade disputes. Although wildfire smoke has been discussed publicly as a cross-border concern, administration officials have stated that the announced tariffs were based on trade issues rather than being imposed directly as compensation for wildfire pollution.

Kronos believes wildfire smoke should be approached primarily as a public-health and emergency-preparedness issue requiring cooperation among communities, government agencies, healthcare organizations and private industry.

Significant New-Customer Discounts and Expedited Fulfillment

For a limited time, Kronos is offering qualifying new customers significant discounts on selected products, including:

• FDA-cleared Kronos air purifiers.
