- Extra gas adsorption: a HEGA carbon cloth on top of carbon and zeolite
- Quiet on low, white noise on high
- Low upkeep: one filter designed to last up to 5 years
What the fifth stage adds
Granular carbon is good at odors, but a carbon cloth has far more surface area for its weight, so more gas molecules have somewhere to stick. The Bedroom Machine wraps a HEGA cloth around its HEPA, adding a final adsorption stage for chemicals and gases after the carbon and zeolite bed has done its work.
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 Bedroom Machine is named for the room Austin Air recommends first: the one you sleep in. It adds a fifth stage to the HealthMate filter, a HEGA carbon cloth, for extra gas and chemical adsorption while you rest.
Air passes through five stages in one filter. Two prefilters catch hair, dust and pollen, about 15 lb of activated carbon and zeolite adsorbs odors and gases, 60 sq ft of medical grade HEPA captures 99.97% of particles at 0.3 microns and 99% at 0.1 microns, and the HEGA cloth adds a very large surface area for chemicals and gases.
Why it belongs in your stack: you spend a third of your life asleep, and the bedroom air is the air you breathe longest. Low speed runs as a soft hum, and higher speeds double as white noise.
Built in a steel cabinet 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
- You want the purifier to live where you sleep and run all night.
- You would like gas and chemical protection on top of HEPA without the most expensive unit.
- A low hum or white noise helps you sleep.
- You prefer a simple dial over apps, sensors or WiFi.
Maybe look elsewhere if
- Your main concern is smoke or chemical off gassing; the HealthMate Plus or Immunity Machine use impregnated carbon for that.
- Your bedroom is small and you want a compact unit; the HealthMate Junior is sized for smaller rooms.

Why it earns a place in the stack. Sleep is where the rest of your routine gets its return, and the bedroom is the room you breathe in longest. The Bedroom Machine adds a HEGA cloth to the HealthMate filter so particles and gases are both handled overnight, quietly, in the Elevate layer.

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.
