Home Air Purification Systems

There are many different choices when it comes to selecting an air purification system for your home / HVAC system. Everyone has some type of basic filtration system, but these systems are not designed to eliminate odors and germs from the air in your home. Actual air purifiers accomplish all of this.

To actually clean the air, there are two main types of systems. UV light systems, and ion type systems. We install and recommend the maintenance free ion based systems from I-Wave.


We offer a range of different home humidification systems, and are more than happy to meet with you to discuss your options. If the air in your home is far too dry during the winter months, this might be a good option for you to consider.


We can certainly sell you filters, but they are typically available for similar prices from local hardware stores or online.

The important note with filters is that we recommend purchasing the least expensive ones possible. The high end options that are marketed for removing all sorts of things from the air in your home are just too restrictive for your heating and cooling system. For proper efficiency and system reliability, air flow is critical to your heating and cooling system.

It is also a good idea to check your filter regularly for this same reason. Blocked filters cause a large percentage of emergency service calls, and this can easily be avoided.
