Indoor air quality · IAQ

Comfort is more than temperature.

Dust, airborne particles, odors, moisture, and ventilation all affect the air inside your home. A thoughtful IAQ upgrade starts with understanding your home and your HVAC system.

Our paired approach combines Scorpion UVC-LED coil treatment with a Healthy Climate® 5-inch MERV 16 filter: two components serving different purposes inside your heating and cooling system.

Two parts, two jobs

Our paired IAQ upgrade

01 / Coil treatment

15-inch UVC-LED coil treatment

Nu-Calgon’s Scorpion uses UVC-LED light directed at the evaporator coil and surrounding surfaces. The manufacturer describes it as a way to reduce biological growth on treated surfaces and help address associated musty or “dirty sock” odors.

Treats coil surfaces reached by the UVC light.
Complements physical filtration.
Installation location and coverage matter.

Scorpion treats surfaces. It does not physically trap dust and is not a substitute for a filter. We confirm mounting, coil coverage, and 24VAC power requirements for your equipment before installation.

02 / Particle capture

Healthy Climate® 5-inch MERV 16

Deep-pleated media filtration

We offer this filtration component as an IAQ upgrade. It does not mean we install Lennox heating or cooling equipment. This deep-pleated media filter captures particles from air moving through a compatible filter cabinet. MERV 16 is a high particle-capture rating; the 5-inch depth describes the nominal filter size, not its efficiency rating.

Helps capture airborne dust, pollen, and pet dander.
Uses replaceable filter media.
Requires a correctly sized cabinet and suitable airflow.

Lennox offers several Healthy Climate variants and sizes. Exact media, carbon features, replacement intervals, and fit depend on the model selected.

Inside your HVAC system

Where do these products go?

These manufacturer illustrations show typical placement. They are not photos of our installations; your equipment layout determines the final design.

Scorpion: at the evaporator coil

The UVC-LED is mounted inside the equipment so its light reaches the coil surfaces. Installation and service are handled by a qualified technician. This is not a room-facing light.

Filter: in the return-air path

The filter sits in a compatible media cabinet on the return-air side, before air enters the equipment. We check cabinet fit, airflow, and access for replacement.

Why combine them?

Capture particles.
Care for the coil.

The filter captures particles from circulating air; the Scorpion applies UVC light to coil surfaces. Together, they address different parts of HVAC air quality. The combination does not make a home sterile or remove every type of pollutant.

What can a filter capture?

CaptiveAire’s “I Built a Laser Fishtank for...Air Filters?” uses laser visualization and measurement to explore airborne particles and filtration.

What MERV means

The rating matters.
So does the installation.

MERV stands for Minimum Efficiency Reporting Value. It measures particle-capture performance across specified particle sizes. It does not measure gas removal or how quickly an entire home’s air is cleaned.

A higher rating alone is not a reason to put a restrictive filter into an unsuitable system. We review cabinet fit, airflow, and pressure drop before recommending a MERV 16 upgrade.

Start with your home.

Tell us about dust, odors, filter concerns, or rooms that feel stuffy. We’ll help identify whether filtration, coil treatment, ventilation, moisture control, or a combination fits your needs.

Filter replacement timing depends on the selected product, runtime, and household conditions. The Scorpion also needs installation and service consistent with its manufacturer’s instructions.
