What Guard does

Know your home. Own your health.

Guard reads the signals in your air that you cannot see or smell. Mold conditions building in the walls. Virus risk rising before flu season hits. Pollen sneaking through the windows. It turns all of it into plain, actionable intelligence so you can stay on top of your game.

Proprietary health intelligence

Your air speaks. Guard translates.

Four indices no other home monitor calculates. Each one updated daily from your live sensor readings, local environmental data, and health risk models. The result is early warning intelligence built specifically around your home.

Mold index logo
Mold Index
Mold waits. Guard watches.
By the time mold is visible, it has been growing for weeks. Guard monitors the humidity, temperature, and airflow conditions that mold needs to thrive and surfaces the risk early, before it becomes a structural or health problem.
Currently: Low risk
Virus index logo
Virus Index
Your home's conditions decide how long viruses survive.
Airborne viruses linger longer at certain temperatures and humidity levels. When those conditions exist in your home the Virus Index rises, giving you a clear signal to ventilate, filter, or act before anyone gets sick.
Currently: Moderate
Influenza index logo
Influenza Index
Cold and flu season starts at home.
Indoor air conditions in winter accelerate influenza transmission even between family members sharing the same house. The Influenza Index tracks those conditions in real time so you can take practical steps at the right moment, not after the fact.
Currently: Low risk
Pollen index logo
Pollen Index
Outdoor pollen counts only tell half the story.
Pollen travels inside and your home's conditions determine how bad it gets. Guard tracks the real indoor picture so allergy sufferers know exactly when to filter, when to close the windows, and when the air is finally safe.
Currently: High — take action
All four indices are available on Guard and Command. Not included in Sense.

For health-conscious families

Smart parents protect their families with facts, not feelings.

Children breathe faster than adults and absorb more of whatever is in the air around them. Guard gives you precise, home-specific intelligence on mold, viruses, and seasonal allergens so you can protect your family with confidence, not just instinct.

For remote workers

When you work from home, your air is your work environment.

Most home offices hit CO₂ levels that would trigger ventilation alarms in a commercial building by mid-morning. Guard's year of trending data shows you precisely when your air starts costing you focus so you can correct it before you lose the afternoon.

Common questions

Answers before you decide.

Sense shows you what your air looks like right now. Guard helps you understand what it means. You get room by room comparisons and four proprietary risk indices covering mold, viruses, flu, and pollen. Instead of reading numbers, you get answers. If you have kids, allergies, a health concern, or simply want to genuinely understand your home, Guard is where the intelligence begins
The Mold, Virus, Influenza, and Pollen indices are proprietary risk scores updated daily using your uHoo sensor readings, local environmental data, and health risk models. Instead of showing you a raw number, they surface a plain-language risk level: low, moderate, or high. So you always know what to do, not just what the data says.
Every Guard subscription includes one uHoo Caeli, our latest sensor. It tracks 9 vital air parameters and updates every 10 seconds. If you want to cover multiple rooms, additional Caeli units can be added to the same user account.
Yes, at any time. If you want to upgrade to Command, we charge the difference in price for the remainder of your billing year and your new features activate immediately. If you decide to downgrade to Sense, the difference becomes a credit applied to your next annual renewal. Your data and device stay with you either way.
Your data belongs to you. It is encrypted end-to-end, never sold, and never shared with any third party. You can export it or delete it permanently at any time from your account settings.
If Guard does not change how you see your home's air, you can cancel the subscription anytime.
