You keep hearing about whole home air scrubbers, whether it is from a technician during a tune-up or from searching online, and you are not sure if it is a real upgrade or just another add-on. A whole home air scrubber is worth it for most homeowners dealing with allergies, pet odors, wildfire smoke, or cold and flu season concerns, since it treats the air moving through your entire duct system instead of only what passes through a filter. It will not fix a leaky duct system, replace regular filter changes, or substitute for duct cleaning. Here is what a whole home air scrubber actually does, what it costs based on our own service records, and when it makes sense to add one to your home for better indoor air filtration in Tacoma and across the South Sound.
What does a whole home air scrubber actually include?
A whole home air scrubber installs directly in your ductwork, usually near the furnace or air handler, and treats the air that moves through your entire HVAC system. Most units use a non-ozone ionization or UV process to reduce airborne particles, odors, and germs as air circulates, rather than only trapping debris the way a standard filter does.
A whole home air scrubber is one of several fixes for poor indoor air quality, and it is usually the right call once the more common culprits are ruled out. If you are not sure what is actually causing the problem in your home, our guide on the most common causes of bad indoor air quality covers all eight, including this one.
In our service records, non-ozone models make up the large majority of the air scrubbers we install and service. That matters, since older ozone-generating models can produce a byproduct that irritates the lungs at higher concentrations. When you are comparing an air scrubber HVAC upgrade to a basic filter change, the biggest difference is coverage: a filter only catches what passes directly through it, while an in-duct air scrubber treats the air throughout the whole system.
Checking the air scrubber is also part of our Precision Tune-Up approach. We maintain what is already working, prevent small issues from turning into bigger ones, and extend the life of the equipment you have already invested in. During a standard cooling or heating tune-up, your technician checks the indicator light and confirms the unit is receiving power.
The benefits homeowners notice most
- Fewer airborne allergens. Homeowners with seasonal allergies or pets often notice less irritation once the system is treating air throughout the home, not just what passes through the filter.
- Reduced odors. Pet odors, cooking smells, and musty basement air are common reasons homeowners in older Western Washington homes ask about a whole home air scrubber.
- An added layer during cold and flu season. Many homeowners install one heading into fall and winter, when everyone is spending more time indoors.
- It works alongside what you are already doing. An air scrubber complements regular filter changes and periodic duct cleaning. It is not a replacement for either.
If you are also considering a deeper clean of your ductwork, our duct cleaning service pairs well with an air scrubber install, since both are frequently completed during the same visit.

What we commonly find, and what it means for your system
A whole home air scrubber installed in the ductwork, with the UV lamp lit and running, treating the air moving through the entire system.
Based on our service records from June 2025 through April 2026, we completed 143 jobs involving whole home air scrubber installation, service, or repair across Western Washington, most often in Tacoma, Lakewood, Puyallup, and Gig Harbor. What we find during those visits usually falls into two categories: what is included in a routine check, and what turns into a separate conversation.
Included as part of a routine visit
During a standard Precision Tune-Up, checking the air scrubber’s indicator light and power connection is included at no extra cost. Your technician will let you know if everything looks normal or if something needs a closer look.
Items that become a separate repair or replacement conversation
Replacement cells or UV bulbs are the most common separate item, showing up in roughly a quarter of the air scrubber visits in our records. These are wear parts, similar to a light bulb, and typically need replacing every one to two years depending on how much the system runs. A brand new installation is the other common request, along with occasional uninstalls when a homeowner is changing systems.
Example From a Recent Service Visit
A homeowner in Lakewood called after noticing the indicator light on their air scrubber had gone dark. During the visit, our technician found the UV cell had reached the end of its normal service life, a routine wear item after several years of regular use.
Solution: We replaced the cell, confirmed the light was back on, and tested the system before we left the Lakewood home.
Is a whole home air scrubber worth it?
For most homeowners dealing with allergies, pet odors, wildfire smoke, or who simply want an added layer of protection during cold and flu season, yes, a whole home air scrubber is worth it. If you already keep up with filter changes and duct cleaning and do not have a specific air quality concern, a simple filter upgrade may be enough on its own.
The value comes down to what you are trying to solve. An air scrubber treats the air moving through your whole system continuously, rather than only when it happens to pass through a filter. It is not a fix for a leaky duct system, a substitute for changing your filter, or a guaranteed cure for every allergy symptom. Every air scrubber we install is backed by our No Worry, No Breakdown Guarantee, so you are covered if something is not working the way it should.

What does a whole home air scrubber cost in Western Washington?
Based on 143 air scrubber jobs in our service records, a standalone installation typically runs from about $1,295 to $1,458, and a replacement cell or bulb typically runs from $99 to $554 depending on whether the visit also includes a diagnostic fee or a full tune-up. Jobs bundled with a new furnace or AC installation, or with a full duct cleaning, can run higher or lower depending on what else is included.
| Service | Typical Cost Range |
|---|---|
| New standalone installation | $1,295 to $1,458 |
| Replacement cell or bulb | $99 to $554 |
| Installed alongside duct cleaning or a new system | Varies with the full scope of the visit |
What drives the spread is mostly whether it is a brand new installation or a routine part replacement, along with whether the visit is bundled with other work like duct cleaning or a system install. Club members also see reduced diagnostic fees, which can lower the cost of a service visit. Ask us about our financing options if you are weighing this alongside other home comfort work.
When should you install or service a whole home air scrubber?
There is no single “right” season to add a whole home air scrubber, but a few timing windows make the most sense for South Sound homeowners. If you are already having duct cleaning done, or installing a new furnace or AC system, adding an air scrubber at the same visit is often the most efficient way to do it. Many homeowners also choose to add one heading into fall, ahead of cold and flu season, or in late summer when wildfire smoke can affect our marine climate air quality.
If you already have a unit installed, plan on checking it during your regular cooling or heating tune-up rather than waiting for the indicator light to go dark. Older homes in our service area, with more moisture and less consistent sealing, tend to benefit the most from ongoing air filtration support.

FAQ: Common Questions About Air Scrubbers

-
A whole home air scrubber is a device installed directly in your HVAC ductwork, usually near the furnace or air handler, that treats the air moving through your entire system. Most models use a non-ozone ionization or UV process to reduce airborne particles, odors, and germs as air circulates, rather than only trapping debris the way a standard filter does.

Based on our service records, a new standalone air scrubber installation typically runs from $1,295 to $1,458. Replacement cells or bulbs for an existing unit typically run from $99 to $554, depending on whether the visit includes a diagnostic fee or a full tune-up.
-
-
No, but it also is not a cure-all. A whole home air scrubber genuinely reduces airborne particles, odors, and germs moving through your duct system, which is different from what a filter alone does. It will not fix leaky ductwork, replace regular filter changes, or guarantee an end to every allergy symptom, so it is worth being clear about what problem you are trying to solve before you install one.
-
-
The replacement cell or UV bulb inside most units typically needs replacing every one to two years, depending on how often your system runs. We recommend having it checked during your regular cooling or heating tune-up rather than waiting for the indicator light to go dark.
-
-
We do not recommend it. A whole home air scrubber has to be positioned and wired correctly inside your ductwork to work as intended and to avoid damaging your system. A licensed technician can also confirm the right model for your home and duct setup before installing it.
-
-
Yes. A whole home air scrubber works alongside your filter, not instead of it. Your filter still needs to be changed on a regular schedule to protect your system and keep airflow steady, even after an air scrubber is installed.
