    Remove unhealthy indoor air and replace it with fresh air from outside without wasting the cooling or heating contained in the air inside.

    We help people, companies and governments make better air quality decisions by providing them with cost effective and reliable instrumentation and information. Our sensor-based instruments and air quality monitoring systems are used widely in outdoor ambient applications as well as indoor air quality and ozone monitoring and control.

    High efficiency air filters

    High Efficiency Pleated Filters are the standard when it comes to most HVAC systems because they are easy to install, come in standard sizes and have a low initial cost. Unlike regular flat filters, high efficiency pleated filters contain media that is folded like an accordion, which allows for greater surface area and lower resistance to air-flow.

    UV light air cleaners

    UV has been proven under numerous studies for its ability to destroy the DNA of germs: viruses, mold, spores, fungi, and bacteria. It works at different levels depending on what one wants to accomplish. In the commercial world, i.e. hospitals, clean rooms and food processing plants, the objective would be to have instantaneous kill. Therefore, UV lights would blanket the air passage system and the airflow directed over and between lamps, which provide for maximum kill of air pollutants. This process is expensive. In residential applications, the objective is to create a cost effective and continuous method of cleaning the air. The kill rate of air pollutants is a function of space, time and the intensity of UV.


    Dehumidifiers use a fan to pull air over two sets of refrigerant-filled coils, one cool and the other warm, wringing out moisture along the way. Dehumidifiers vary according to how many pints of moisture they can remove in 24 hours. We also provide unbiased Ratings and dehumidifier reviews to help you choose the best dehumidifier for your needs.


    Our customers often ask us whether they should choose a warm or a cool mist humidifier. To simplify the answer, our years of experience (along with doctor and allergist recommendations) have proven that a cool-mist humidifier is best used to combat allergies while a warm-mist humidifier offers relief for those with asthma, a cold, the flu or respiratory infection. Other symptoms such as dry skin, swollen nasal passages, sinus headaches, and asthma will also be relieved while in a well humidified room. As a first step, our product experts recommend placing one of our virtually-silent ultrasonic humidifiers in each of your bedrooms for improved sleep. Many of our ultrasonic humidifiers deliver both warm and cool mist with the touch of a button. Larger, fan-based humidifiers are recommended for humidifying larger, open areas of your home.
