Why the carbon is impregnated
Plain activated carbon holds many odors and gases, but some of the most common indoor chemicals, like formaldehyde, slip past it. The HealthMate Plus blends in carbon treated with potassium iodide, which is designed to adsorb those harder compounds, alongside zeolite for gases like ammonia. The HEPA behind it still handles the particles.
It is an air purifier that filters the air in a room; it is not a medical device and does not treat, cure, or prevent any condition.

Description
The HealthMate Plus is the Austin Air unit for chemicals: smoke, traffic fumes, VOCs and the off gassing that comes with new furniture, flooring and paint. It uses the same steel cabinet as the HealthMate with a filter built for heavier chemical loads.
Air passes through four stages in one filter. Two prefilters catch hair, dust and pollen, about 15 lb of activated carbon, potassium iodide impregnated carbon and zeolite adsorbs gases including formaldehyde and benzene, and 60 sq ft of medical grade HEPA captures 99.97% of particles at 0.3 microns and 99% at 0.1 microns.
Why it belongs in your stack: the chemicals you cannot see or smell are part of the air you breathe at home. This unit is built to keep them down in the rooms you use most.
Built for larger rooms, with casters and a filter designed to last up to 5 years. It belongs to the Elevate layer of the Kove stack: the environment you recover in.
Is this right for you?
You'll get the most from it if
- Smoke, traffic fumes or wildfire season are part of your year.
- You live with new furniture, flooring, paint or a recent renovation.
- You are sensitive to chemicals and odors and want the heavier carbon blend.
- You are filtering a larger room and want one unit that also covers dust and pollen.
Maybe look elsewhere if
- Your concern is mostly dust, pollen and general air quality; the HealthMate does that for less.
- You only need a bedroom, office or nursery; the HealthMate Plus Junior is sized for smaller rooms.

Why it earns a place in the stack. Off gassing, smoke and traffic fumes are the part of indoor air most purifiers handle worst. The HealthMate Plus puts impregnated carbon in front of its HEPA so chemicals get the same attention as dust, running quietly in the Elevate layer of your home.

Our approach
Every product earns its place.
No single thing changes your biology on its own. What matters is the system, and whether each piece earns its place. Here is how a device makes it into Kove.
01
Start with the evidence
Where there is research behind how something works, we read it. We look at the real mechanism a device relies on, like the wavelength, the frequency, or the dose, and whether the evidence holds up. Substance comes before marketing, and we are honest about how strong that evidence is.
02
Separate mechanism from marketing
A claim is not a mechanism. We check a device's real output against its stated one: does the panel emit the 660 and 850nm it advertises, at the irradiance that makes those numbers matter? The marketing language gets set aside. The measurable spec is what we judge.
03
Verify build and dose
Even a good idea does nothing if the hardware is weak. We confirm the output is consistent, the dose is usable in a real daily routine, and the build holds up over years, because a device only helps if it lasts as long as the habit.
04
Held to one standard
What clears every step earns its place in the system, held to the same standard as everything else. That consistency is what you can count on.
