UV light intensity

Ionizers are not very effective at lowering mold counts. UV light can reduce mold, but the application to large areas is problematic.

UV light intensity, which decreases rapidly with distance from the bulb, must dose the mold for a time measured in minutes. Air purifiers with uv tend to use it on the filters or to activate photocatalysts. The best application of uv in a mold allergy situation is for disinfecting air conditioning coils and evaporation pans.

Newer air purification technologies are arriving that will surpass ozone for normal household mold remediation. These 無線充電座 are hydroxyl radical oxidizers, safer with their short lives, and photocatalytic oxidizers, which burn microorganisms with high tech semiconductors. Sharp FPN60CX would be a good alternative to ozone for a mold situation, but only for a limited room size, say under 200 square feet. The portable Sharps could easily be moved to the mold source, i.e. kitchen or bath.

Photocatalytic air purification, without paper filters, thrives in damp environments. A new and inexpensive model, the Nanobreeze, would do well in localized damp areas like baths and kitchens.

Control moisture with source removal and dehumidifiers.

When moisture is gone, properly sized HEPA air purifiers are effective at purifying airborne mold. Dedicated air sterilizers, such as Airfree and Eco-rx can help after the moisture is removed.
