# Mold | C-POLAR Source: https://cpolar.tech/contaminants/mold/ Explore mold and fungal spores, and the NanoFlashing™ approach to capturing and destroying them. This is the text of that page, in a form a machine can read. Nothing in it is paraphrased or shortened. After it come short extracts from other C-POLAR pages, each quoted word for word with the page it comes from. --- ## Mold ## Mold survives almost anything, and it's negatively charged Mold is one of the most common indoor allergens, and one of the hardest to get rid of. Its spores shrug off heat, drying, even bleach, then grow back wherever they land. The [EPA warns](https://www.epa.gov/mold/mold-and-health) that breathing it can trigger allergic reactions and asthma attacks. Researchers [estimate mold sets off 4.6 million asthma cases a year](https://pubmed.ncbi.nlm.nih.gov/17542835/). It hits home value, too: mold is a defect sellers must disclose, and [cleanup routinely runs into the thousands](https://www.angi.com/articles/how-mold-can-impact-value-your-home.htm). And every spore [carries a negative charge](https://www.sciencedirect.com/science/article/pii/S092325081100146X). ### Mold reaches every region, and it swells with the season Outdoor mold is everywhere, and it swells through summer to a peak in [late summer and fall](https://www.epa.gov/mold/mold-and-health). About [half of U.S. homes](https://pubmed.ncbi.nlm.nih.gov/17542835/) already have a mold or dampness problem. Mold Level Lower Higher August 8 / 12 ## What mold does to you The filter grows the mold it caught 99.99% of captured mold spores shed back off a loaded filter. The media becomes the source. A conventional filter catches mold spores, but it does not kill them. In the warm, damp media, the spores stay alive, settle in, and grow. The University of Cincinnati measured a loaded filter [shedding up to 12% of the mold spores it caught](https://www.sciencedirect.com/science/article/abs/pii/S0021850200000173) back into the air, about 60 times the rate of plain dust. The filter meant to remove mold becomes one of its sources. A heavier load sheds more of it back into the air. The Technical University of Denmark measured office staff [about 10% slower](https://pubmed.ncbi.nlm.nih.gov/15663456/) behind a used filter than a clean one. A loaded filter also drags down the whole room it feeds. Airborne mold spores 136 million spores per sample 40,000× the standard test dose 1.6 m/s airflow NanoFlashing™ Control NanoFlashing™ captures the mold, and destroys it Independent testing shows NanoFlashing™ destroys up to 99.99% of a broad spectrum of fungal spores through a physical mechanism. Researchers at Massachusetts General Hospital and Harvard Medical School, in a study with funding from the U.S. National Institutes of Health, tested NanoFlashing™ the hard way, more than 100 million live, dry spores, driven in by fast-moving air in just three minutes, the way mold actually reaches a filter.
