And as long as you're keeping your fan running, the environment it creates is hostile to mold growth. In other words, the mold you can see trapped is better than mold that’s in your air. Consequently, if you see pollutants on the filter when tested, then our filter is performing properly.” Our internal testing conducted using industry-accepted protocols demonstrates that if mold enters the machine, any captured particles on the HEPA filter – mold included – will not multiply and will not be released back into the air from inside our machine. “Dyson purifiers, including Cryptomic, feature fully-sealed filter systems. The filters were removed from the units and tested independently of their systems. Both had been treated with the same amount of mold spores directly applied to the filter on the previous day.ĭyson requested that I clarify the method used for these tests. Rahmy Tawfik, Research Microbiologist, fired up the electron microscope and trained it on two different samples - one from the filter of a Dyson Cryptomic and one from a Molekule. I got to see this in person when we headed over to one of several research labs Molekule has on campus. Particles that make it through the pre-filter are then trapped on their specially-coated filter and the UV light in the unit then bursts the cell walls and completely eliminates them. PECO uses a photochemical reaction to break down contaminants and kill mold spores.

That's why the light technology Molekule employs is so important. Molekule never implied that this would happen on a regular basis in a normally operating Dyson air purifier - AK) Mold can grow on HEPA filters, eventually breaking through to the other side and releasing spores into the air with the help of your air purifier. ( This would only happen in the most poorly maintained of filters that weren’t kept in proper working operation. Or, even worse, multiply on the filter itself. In fact, the mold, bacteria, allergens, and volatile organic compounds (VOCs) that they collect can build up over time and be released back into the air. However, just because they're great at capturing things doesn't mean those things are gone for good.
