Air Filtration Systems:

Air filtration is very important to your health and to your equipment. Air filters are installed on forced hot air, hydro air, and air conditioning and heat pump systems. Air filters come in many sizes and efficiency ratings. Most filters are installed on the return of your equipment. Some are installed at the beginning of your return ducting. When your system is started by the thermostats for either heat, cooling or fan on for circulation, air is moved across your filter where the small airborne particulates get trapped making the air that is recirculated through your equipment and into your home cleaner and healthier.


No moving parts; filters are a basic but very important piece of your equipment. There are many types to fit any application.


There are no disadvantages to filtering your air. It is necessary for health and well-being.

Case Study – Allergy Prone Child

Requires the cleanest indoor air

Do you know that the air quality inside your home may be worse than the pollution in the air outside? That is true, and this can be especially harmful to children (or adults) with allergies … or illnesses such as asthma.

Allergies can be triggered by breathing dust, molds, spores, or pet dander, so when we were called in to add an air cleaner to a customer’s heating system, we recommended the high-efficiency central air cleaner from Aprilaire.

It can be connected to the home’s central heating or cooling system and it operates when you want, out-of-sight and silently. It traps pollen-sized particles, helping to minimize the risk of asthma and allergy attacks. The disposable filter lasts one to two years, so there is no need for monthly filter changes.

Best of all, you can choose to run the air cleaner constantly 24 hours a day or 30 minutes every hour, or only when you have guests or when vacuuming! This control is invaluable for those days when the pollen counts are high!
