Air Purification in Spokane

Whole-Home Air Purifier Installation from a Carrier-Certified Heating & Air Conditioning Team

We install whole-home air purification systems that integrate directly into your existing HVAC ductwork, treating every cubic foot of conditioned air throughout your home continuously. At Sturm, we’ve served Greater Spokane homeowners since 1945, and we back every installation with NATE-certified technicians and full licensing and insurance.

Whole-home systems are a different category from portable room purifiers and standard HVAC filters. They address airborne allergens, bacteria, viruses, mold spores, VOCs, and odors at the source rather than waiting for particles to settle or cycle back through a filter. According to the EPA, indoor pollutant concentrations are typically two to five times higher than outdoors. In Spokane, the local climate pushes that number harder than most.

Why Spokane Homes Need More Than a Standard Filter

Spokane’s cold winters keep homes sealed for months, letting allergens, dust, and indoor pollutants accumulate without fresh air exchange. Dry summers bring their own challenge: wildfire smoke can penetrate even closed homes, adding fine particulate matter that standard HVAC filters aren’t built to handle. High-efficiency purification systems can significantly reduce indoor smoke particle load during those stretches.

Standard filters do their job on larger particles like dust and hair, but they let microfine allergens, VOCs off-gassed by furnishings and building materials, bacteria, viruses, and mold spores pass through and recirculate. If you notice persistent allergy or respiratory symptoms, stale or chemical odors, or heavy dust buildup around your vents, your filter alone isn’t enough.

The Carrier Infinity Air Purifier

We install the Carrier Infinity air purifier, a whole-home filtration system that works with your existing HVAC unit. Its three-stage process sets it apart from standard filtration.

• Stage 1: Precision-Point Ionization. An ionization array charges airborne particles as they enter the system.
• Stage 2: Electric Field Capture. Charged particles are drawn to a purification cartridge within an electric field.
• Stage 3: Inactivation. Captured microorganisms are subjected to electrical current and ion bombardment, inactivating them.

The Carrier Infinity carries a MERV 15 filter rating, trapping 95% of particles from 1.0 to 3.0 microns and 85% of particles as small as 0.3 microns. It inactivates 99% of airborne viruses and germs caught in the filter, including human influenza, coronavirus, the common cold, and the bacteria responsible for strep throat. An activated carbon filter handles VOCs and odors. A smart sensor monitors pollution levels and automatically adjusts the three-speed fan to match conditions.

The system comes in multiple sizes to fit different homes and is backed by a 10-year limited warranty on parts. As a Carrier Certified Ductless Pro, we meet Carrier’s criteria to sell, install, service, and maintain their equipment.

The REME HALO In-Duct Air Purifier

The REME HALO takes a fundamentally different approach. Rather than waiting for contaminants to reach a filter, it actively pursues them. Installed in the supply plenum of your HVAC ductwork, it emits ionized hydroperoxide plasma through the air handler and duct system into your living spaces, targeting bacteria, viruses, and fungi at their source.

UV sanitizing lights work alongside low levels of hydrogen peroxide to reduce airborne and surface-level microorganisms. Smoke, cooking, mildew, and dirty laundry odors are addressed by reducing the germs and toxins that cause them, not by masking them. The system also captures microfine particles and VOCs that upgraded HVAC filters still can’t catch.

The REME HALO runs whisper-quietly without adding operational noise to your system. By reducing debris that reaches components like furnace thermocouples and AC evaporator coils, it supports efficiency and can support longer equipment lifespan. It installs into new or existing HVAC systems with ductwork.
