What exactly is ozone?

• Ozone (O₃) is a highly reactive gas made of three oxygen atoms. Naturally occurring in Earth’s upper atmosphere, ozone effectively destroys bacteria and viruses. Greentech products use ozone to mimic this natural sanitizing process safely indoors.

How does ozone purify indoor air?

• Ozone actively attaches itself to airborne pollutants such as viruses, bacteria, and allergens. Through oxidation, it neutralizes these contaminants at a molecular level, eventually reverting to harmless oxygen molecules.

Is ozone safe to use indoors?

• Yes. When properly controlled and used responsibly, ozone is safe and highly effective for air purification. Greentech Environmental products strictly adhere to safety standards, ensuring ozone emission stays well within recommended guidelines.

Does ozone remain in the air after purification?

• No. After ozone interacts with contaminants, it transforms back into regular oxygen, leaving no harmful residues—only fresh, purified air.

Why choose ozone-based air purification?

• Ozone purification is exceptionally effective because it directly targets and neutralizes pollutants at their source. It provides rapid, thorough air sanitization, promoting healthier indoor environments naturally and safely.

How does ActiveHEPA+ differ from regular HEPA purifiers?

ActiveHEPA+ combines active purification technologies with traditional HEPA filtration and proprietary OdoGard® odor-neutralizing coating, offering a more thorough cleaning of the air.

Is the ActiveHEPA+ purifier safe for use around children and pets?

• Yes, it is UL 2998 certified as ozone-free, making it completely safe and effective for homes with children and pets.

Can ActiveHEPA+ reduce viruses and bacteria effectively?

• Absolutely. Laboratory tests confirm the purifier removes up to 99.98% of airborne viruses, including SARS-CoV-2.

How frequently should the filters be changed?

• Typically, filters should be replaced every 6-12 months depending on usage and air quality conditions.

Does ActiveHEPA+ remove cooking and pet odors effectively?

• Yes, the unique OdoGard® coating actively neutralizes odors at a molecular level, significantly improving indoor air freshness.
