Did you know?
According to the EPA, your indoor air is more than 2-5 times more contaminated than outdoor air. It’s a fact, and studies show we spend more than 90% of our time indoors! No wonder why doctor visits and allergy medicines have sky rocketed. Our air cleaners/filters can stop the wheezing, sniffing and watery eyes by trapping up to 99.99% of all allergens from the air. For odors from pets and damp homes, take a look at our product line of UV Lights and Dehumidifiers. UV Lights remove harmful Volatile Organic Compounds (VOCs) from the air that also causes allergies. Dehumidifiers remove excessive moisture from homes that causes mold, mildew, and dust mites.

Did you know?
Humidifiers add moisture.
According to the EPA, you should have 35%-60% humidity in your home. Anything less could cause nose bleeds, static, upper respiratory infection, squeaky floors, asthma-like symptoms and excessive dust mites. Please give us a call at 314-367-4442 for a free estimate and we’ll gladly assist you.
Remember, we specialize in creating a healthy environment for you and your family…
