A healthy home begins with cleaner air. Improve the air quality in your house by reducing the amount of airborne odours with a Filtrete™ Odour Reduction Filter. This electrostatically-charged air cleaning filter attracts and captures large and microscopic airborne allergens and uses activated carbon to absorb odours out of the your air and into the filter. For maximum performance, replace your Filtrete™ Filter seasonally (every 90 days) to ensure you and your household are breathing cleaner air.
