10 Best Ozone Purifiers 2025 in the United States

The Enerzen O-888 Industrial Ozone Generator is a robust choice for eliminating tough odors in various environments, including rooms, cars, and spaces affected by smoke, pets, or mold. With a high ozone output of 70,000 mg/h, it can handle large areas effectively. The unique pulsating feature enhances its odor removal capabilities, making it particularly useful for stubborn smells.

Operating the device is straightforward; users simply set the timer and vacate the area, allowing the machine to do its job, which is a practical safety feature given the necessity to avoid exposure to ozone during operation. The noise level of 30 dB means it operates quietly, which might be beneficial in settings where noise is a concern. The product is also CE certified, ensuring compliance with European safety standards.

It is essential to note that it should only be used in unoccupied spaces due to the potential health risks associated with ozone exposure. Additionally, it is not available for sale in California, which may limit accessibility for some users. This machine is ideal for users who need a powerful odor elimination solution and are aware of the safety protocols required when using ozone generators.

The Honeywell InSight Series HEPA Air Purifier is designed for extra-large rooms, making it suitable for areas up to 500 sq. ft. It circulates air effectively, providing almost five air changes per hour. This ensures thorough coverage and efficient purification. The combination of a HEPA filter and a carbon pre-filter works well to reduce allergens, smoke, dust, pollen, pet dander, and odors. This makes it a good option for households with pets, smokers, or allergy sufferers.

An automatic cleaning feature that monitors air quality and adjusts the settings ensures consistent air purification without constant manual adjustments, adding to its convenience. The purifier is AHAM Verified and Energy Star Certified, confirming its reliable performance and energy efficiency. The noise level is 55 dB, which is moderate and may be noticeable in quieter environments but not overly disruptive in most homes.

On the downside, it lacks ozone output, which is a key spec for an ozone purifier. It also does not have advanced control settings beyond basic button controls. The purifier uses genuine Honeywell filters, ensuring dependable performance, but this means recurring costs for filter replacements. At 20.5 pounds, it's relatively heavy but doesn't require assembly. In summary, the Honeywell InSight Series is a robust air purifier suitable for large spaces and those needing strong allergen and odor control, although it does not fulfill the ozone output requirement for an ozone purifier.
