Ozone Filters
Servicing all of Central Massachusetts
Ozone (O₃) is a well-known air pollutant that can seriously impact respiratory health, particularly in vulnerable populations such as children, seniors, and individuals with asthma or other lung conditions. In Central Massachusetts, ozone levels tend to rise during warmer months due to smog, vehicle emissions, and industrial activity — especially in more urbanized areas like Worcester, Marlborough, and Fitchburg.
While ozone is often associated with outdoor pollution, it can also be produced indoors by certain appliances and air purifiers, particularly those that use ionizers or UV light. Some of these devices are marketed as air-cleaning solutions but may emit ozone as a byproduct, sometimes at levels that exceed EPA safety recommendations for indoor air.
Before buying or using any air purifier, it’s important to verify that the product is certified ozone-safe. Look for devices labeled as “CARB-certified” (California Air Resources Board), which ensures minimal or no ozone emissions.
To safely reduce or filter ozone indoors, the following air purification systems have been shown to be effective:
Activated Carbon Filters
Ozone is a highly reactive gas due to its unstable third oxygen atom, which readily detaches and binds with other molecules. Activated carbon filters offer a dense network of adsorption sites where ozone molecules break apart, converting O₃ into stable oxygen (O₂). High-quality carbon filters can reduce indoor ozone levels by up to 70%, especially when used in well-sealed indoor environments.
PECO (Photo Electrochemical Oxidation) Air Purifiers
PECO technology, used in air purifiers like Molekule, initiates a photocatalytic reaction that breaks down ozone and other pollutants at a molecular level. These systems are designed to destroy pollutants rather than just trap them, making them an advanced option for households with persistent indoor air quality concerns.
Purafilter Systems
Primarily used in commercial buildings and healthcare facilities, Purafilter systems combine activated carbon with sodium permanganate, a powerful oxidizing agent. Though more common in large-scale applications, similar filter media can be installed in high-performance home HVAC systems for superior ozone and VOC control.
Passive Filtration
A growing number of homes and schools in Massachusetts are adopting passive ozone control materials, such as activated carbon-infused mats or perlite-based ceiling tiles. These materials provide long-term ozone reduction without needing power or maintenance and are especially effective in buildings with limited mechanical ventilation.
Takeaway for Central MA Residents
As public awareness of indoor air quality increases across Central MA, so does the need for responsible filtration choices. While some air purifiers unintentionally introduce ozone into your living space, certified technologies like activated carbon filters and PECO systems provide safer, proven alternatives. Whether you're in a high-traffic area like Worcester or a rural town near Leominster or Rutland, reducing indoor ozone is an important step toward creating a healthier home environment.
