Mold, unfortunately, exists in every household no matter how perfectly you maintain your home. It just so happens to be a natural part of the air in any home, but only becomes a real issue if it is given the opportunity to grow and spread. If mold is given the chance to grow and spread it can start to cause respiratory problems, especially in those with suppressed immune systems, who suffer from allergies or have asthma-related issues. Some common indicators of mold can be discolorations in your ceiling, wall, or floor. The color of mold can range from black, blue, orange, red, violet, white, or yellow.

Lastly, the size of the spot can vary from small patches to large spots, those large spots are a cause of concern and should be paid attention to as soon as possible.

While they all share common characteristics, they can vary in color, appearance, and other features. It is important as a homeowner to know about the different types of mold and how it can affect you.


One type of mold that is commonly found in homes is Penicillium. Penicillium is a form of mold that is frequently found in things like insulation, carpeting, wallpaper, and rotting fabrics. The big recognizable feature for this type of mold is the color in which it appears in your home. Unlike most molds that are dark colors like black and brown, Penicillium is more of a blue, green, and yellow hue.

Mold is usually classified as toxic and detrimental to our health, however, Penicillium actually can aid our health in a different way. It has medical use as a key substance in a beneficial antibiotic because of the mycotoxins it contains. Nevertheless, this type of mold can still be toxic to your health so taking steps in removing it from your home is important.

Well, your home may have traces of Alternaria mold somewhere hidden causing you to experience these symptoms. Alternaria is one of the most common types of mold and ranks as the primary cause of allergic reactions. The conditions also play a key role in the development of this type of mold, as it thrives during the summer when dry winds move spores indoors. The best place to look for this mold is in wet areas because it is usually found after water damage or a flood.

This mold tends to grow around dust mainly on walls, clothing, and paper and you can see it has a yellowish-green appearance.

C. Jones  

“My daughter recently moved into a new apartment. It has about 650 square feet of living space and unfortunately a connecting neighbor frequently cooked with curry. The smells bothered me quite a bit and the apartment complex did what they could to seal some of the potential areas it may have been coming in. Even with these fixes the odors were bothersome and gave me a headache. We got an EnviroKlenz Air System and we noticed a big change that very weekend – even with the neighbor cooking.”

Marian J. Cohen  

“After three weeks of research, and a final consult with my Naturopath, I purchased the Enviroklenz air cleaner. It has run beautifully now non-stop for the last 6 months. I LOVE IT! It instantly removes any odors from the house, along with allergens and other worrisome airborne stuff. I no longer fear my chain smoking neighbor will pollute my apartment and have been able to sleep throughout the night for the first time in 7 years. 5 star plus”
