Air Filtration in Rancho Santa Margarita

Whole-Home & Commercial Air Filtration From a Team Rooted Here Since 1989

Since 1989, Lewis Air Services has helped Rancho Santa Margarita homeowners and businesses breathe cleaner air. We install and service a full range of air filtration and indoor air quality solutions, from Trane air filters to electronic air cleaners, germicidal UV lights, and air purification products. As a Trane Distinguished Dealer of the Year with NATE-certified technicians, we assess each property individually and recommend the right system for it.

South Orange County’s Mediterranean climate keeps HVAC systems running most of the year. Many RSM homes built in the 1980s and 1990s were designed for energy efficiency, with tight-home construction that limits natural air exchange. The result: indoor pollutants accumulate rather than disperse, making filter performance a year-round concern, not a seasonal one.

Why Your HVAC Filter Isn’t Enough

The standard filter in your HVAC blower compartment has one primary job: protect the equipment from dust and debris. It wasn’t engineered to improve the air occupants breathe. Larger particles like lint get caught, but fine allergens, mold spores, bacteria, and airborne pollutants pass right through.

Dedicated air filtration systems, including media filters, electronic air cleaners, and whole-home purifiers, are designed to capture those smaller particles and reduce asthma and allergy triggers throughout the home. The key variable is the MERV rating, a scale that measures how effectively a filter captures particles. Higher MERV ratings trap finer particles, but a filter that’s incompatible with your system can restrict airflow, reduce efficiency, and drive up energy costs. That’s why professional sizing and selection matter before any product goes in.

Air Filtration & IAQ Products We Install

We don’t carry a single product and fit everyone into it. Before recommending anything, our technicians assess your system type, home or building layout, ductwork condition, and any occupant health concerns like allergies, asthma, pets, or smoke. Then we design a plan specific to your space.

Trane Air Filters
As an authorized Trane dealer, we install Trane air filters sized and rated to work with your system without compromising airflow or efficiency.

Electronic Air Cleaners
These systems use an electrical charge to attract and trap particles too fine for standard media filters, including fine dust, pollen, and other small airborne contaminants.

Germicidal UV Lights
Installed within the HVAC system, germicidal UV lights can inactivate biological contaminants such as mold spores and bacteria on coil surfaces and in circulating air before it reaches your living space.

Air Purification Products
For households or commercial spaces with elevated IAQ concerns, we offer air purification products that complement filtration with an added layer of whole-home treatment.

Why Duct Cleaning Belongs in the Conversation

Even a high-performance filtration system delivers diminished results when air travels through ducts carrying accumulated dust, debris, or biological growth. Dirty ductwork contributes to indoor air contaminants, and no filter fully compensates for what the ducts are putting back in. We offer duct cleaning alongside air filtration work, and when an IAQ assessment reveals that both the equipment and ductwork need attention, we address both in a single plan.
