What is a normal mold spore count?

200-500 spores – the most common species (Penicillium/Aspergillus, Cladosporium and Curvularia) are not an issue and stay within the normal range. 500-1500 spores – sometimes the Penicillium/Aspergillus & Cladosporium levels are in this range and do not require remediation.

Keeping this in consideration, what is a high spore count of mold?

Mold spores are natural part of our environment. Mold concentration in outdoor air depends on a season. In spring summer and fall, spore count can be very high up to 50,000 counts. It is normal to find small number of mold spores in the indoor air.

Furthermore, is Aspergillus Penicillium black mold? The common indoor molds are Cladosporium, Aspergillus, Stachybotrys, Fusarium, Penicillium, and Alternaria. Stachybotrys, or black mold, is commonly recognized as the most dangerous of the mold species Stachybotrys chartarum. These types of mold are very dangerous if allowed to colonize in a home.

People also ask, how many mold spores are in the air?

Mould spores are tiny structures produced by moulds for reproduction purposes. They are so small that we can hardly see some of them even when magnified 400 times. One cubic meter of outdoor air may contain as many as 1,000,000 spores. The volume of air we inhale at rest is estimated at 10 litres per minute.

What are the levels of mold?

Mold Levels in House. The different stages of mold damage are usually divided into five levels. Level one is the level with the least contamination and level four is the one with the greatest degree of contamination. Level five refers to mold growth in the HVAC system.
