Active purification for the whole house

A filter can only catch what passes through it. A whole-home air scrubber installs in your ductwork and actively treats the air in every room — using technologies like UV-C light and photocatalytic oxidation to break down odors, germs, mold, and chemical vapors that filters leave behind. Many systems also help reduce contaminants on surfaces, not just in the air.

What an air scrubber adds

  • ✓Reduces odors filters cannot capture — cooking, smoke, and pet smells
  • ✓Targets airborne germs, viruses, mold spores, and bacteria with UV-C and active purification
  • ✓Helps break down VOCs and chemical vapors from cleaners, paint, and new furnishings
  • ✓Treats the air in every room — installed in your HVAC, not a single-room unit
  • ✓Some systems also help reduce contaminants on surfaces and inside the ductwork

How it works

A whole-home air scrubber installs into your existing ductwork near the air handler. As your system runs, the scrubber uses UV-C light and/or a photocatalytic process to neutralize pathogens and break down odors and VOCs, then circulates the treated air to every room in the house.

Good to know: An air scrubber complements — it does not replace — good filtration; the best results come from a quality filter plus a scrubber. Some ionizing devices can produce small amounts of ozone, so we focus on systems suitable for occupied homes and will walk you through the options.

Frequently Asked Questions

What is the difference between an air scrubber and a filter?
A filter physically traps particles as air passes through it. An air scrubber actively treats the air — reducing odors, germs, mold, and VOCs that filters do not remove — and reaches every room through your ductwork. They work best together.
Does an air scrubber really reduce germs and odors?
Quality whole-home scrubbers using UV-C and photocatalytic technology can meaningfully reduce airborne microbes, odors, and VOCs. Results vary by system, home size, and how often your HVAC runs, so we set realistic expectations for your home.
Do air scrubbers produce ozone?
Some ionizing devices produce trace ozone. We focus on systems suitable for occupied homes and will explain the technology and any considerations before installing anything.
Will an air scrubber help with allergies, pets, or smoke?
Yes — by reducing airborne allergens, pet odors, and smoke-related odors and particles throughout the house. For allergy households we usually recommend a high-efficiency filter plus a scrubber.
Can you install an air scrubber on my current system?
In most cases, yes. Whole-home air scrubbers install into the ductwork of most central HVAC systems. We will confirm compatibility and recommend the right unit for your home.

I cannot thank South County Air Services enough for impeccable customer service. Behshad came out on a Saturday to check my heating unit (failing motor). He was professional, knowledgeable, courteous and thorough – extremely fair pricing, with open and honest communication. Highly recommend. Five star plus!

Super impressed with our experience. We needed to replace our 40+ year old furnace, and from the first call everything was easy and clearly explained. Responsive, great follow-up, great pricing, timely booking, installers on time and prepared, clean install, no mess left.

I am grateful to the technician who inspected my HVAC system today. I feel he did a thorough inspection and told me the truth about my unit. I had two other companies beforehand – the first gave me a report that would call for major expenditure.

You will not find a more honest and knowledgeable HVAC tech. They show up on time and are very professional, but most of all will not try to upcharge you. He could have charged me significantly more but cares about diagnosing the actual problem. I found my HVAC tech – 10 star review if I could!

It’s not often you find an honest business willing to give suggestions over the phone to troubleshoot why my HVAC wasn’t working – without charging me. After a couple minutes we determined my breaker popped and all I needed was to reset it. I appreciate Behshad and will definitely use him in the future.

I spoke with the owner on a Saturday morning and he was at my house within 45 minutes. Another company wanted $3,000 in repairs; Behshad recommended a simple $250 repair that fixed the issue. Very honest, thorough, and reliable!
