Our dual True HEPA and pre-filters capture at least 99.97% of airborne contaminants* in one pass and helps circulate the air of an average classroom** 5.2 times per hour.

Portable True HEPA Air Purifier Replacement Filter Kit includes two replacement filters. Dual HEPA filters (filter lifetime is 1600 hours or approximately 1 year of use in a school setting).

Air purification is a key component in improving air quality indoors. There are many benefits to having good air quality including increased student engagement, improved well-being for allergy and asthma sufferers and reducing the transmission of viruses, including COVID-19. The virus spreads through aerosolized particles that tend to hang in the air unless they are blown away or removed; air purifiers can do both.

To prevent the spread of airborne viruses indoors, the air should be refreshed five to six times per hour, however, over half of existing school and building ventilation systems are outdated and achieve less than that. Placing portable air purifiers in these spaces helps reduce the amount of airborne contaminants, including viruses by refreshing and purifying the air as it passes through its filters.
