For homeowners & renters

Stop guessing whether the air in your house is fine.

A kit of monitors, sized for your rooms, that ships preconfigured and starts reporting the moment you plug it in. You see particles, CO₂, humidity and radon against the air outside, and you can tell whether anything you change actually helps.

Live · Columbus, OH US AQI
Outdoor air Good

Indoor, measured Untested

The outdoor number is published every hour. The one for the room you are sitting in stays a question mark until somebody measures it.

Outdoor air quality in Columbus, OH: Good. US Air Quality Index 24.
What it measures

Eight readings, taken continuously, in the rooms you actually use.

Every reading is kept, so you can look back through a week or a season rather than at one afternoon.

  • PM2.5

    Fine particles from smoke, cooking, pollution and dust

  • CO₂

    How stale the air gets in closed bedrooms and offices

  • Temp · RH

    Temperature and relative humidity, room by room

  • VOCs

    Off-gassing from cleaning products, paint and new furniture

  • Radon

    Long-term exposure, the one that needs months of data

  • Pressure

    Barometric context for what the other readings are doing

  • Outdoor AQI

    The reference next door, so indoor numbers mean something

  • History

    Every reading kept, so you can compare this week to last month

How it works

Order it, plug it in, look at it in a month.

Nobody comes to the house and there is nothing to book. It ships anywhere in the US.

  1. 01

    Size your kit

    Pick how many rooms you want covered. Most homes start with a bedroom, a main living space, and one outdoor reference.

  2. 02

    It ships to you

    Preconfigured and paired before we box it up, so there is nothing to set up at your end beyond power and a wifi password.

  3. 03

    Plug it in

    Power and wifi. Readings start appearing within a few minutes of the first monitor coming online.

  4. 04

    Watch what changes

    The weeks after are the useful part. You find out whether the purifier helps and whether the bedroom is stuffy by 3am, instead of guessing.

What it's for

The numbers are only useful for the decisions they settle.

Most air quality advice has to be generic, because nobody has any data about your particular house. A kit gives you that data.

  • Whether a room purifier is actually clearing the room, or just making noise
  • Whether a MERV 13 filter upgrade changed anything measurable
  • Which bedroom is stuffiest overnight, and by how much
  • Whether opening windows helps or hurts on a given day
  • How long it takes your home to recover after cooking
  • Whether the basement needs radon mitigation
  • Which rooms are worth treating first, before spending on HVAC
  • Whether outdoor conditions are actually reaching you indoors
Bad-air days

When the air outside turns bad, your house has to run differently.

Smoke season and long inversions are when generic advice is most likely to be wrong for your particular home, which is exactly when your own readings are worth having.

Smoke events

Wildfire smoke can sit over a region for days. Seal up, run the right purifiers in the right rooms, and watch indoor particles come down while outdoor ones don't.

Trapped-air spells

Winter inversions and still, cold weather hold pollution down at ground level. On those days the useful thing is knowing when to leave the windows shut and the whole-house fan off.

  • When to close windows, and when to leave them open
  • Which purifiers to run, in which rooms, at what speed
  • Which room is worth turning into a clean-air room
  • When a filter change is actually due during an event
  • How to read outdoor air data before deciding anything
  • How to cut indoor particle sources while the outside air is bad
Who this is for

A kit is worth it if…

  • Wildfire smoke reaches you for part of the year
  • There are kids, older adults, asthma or allergies in the home
  • You live somewhere with winter inversions or long closed-up seasons
  • You have mini splits, radiators, or no central air
  • You're not sure which purifier or filter setup is right
  • You want data before spending on HVAC or filtration upgrades
  • You rent, and want to know what you are breathing without changing anything
Renting?

Nothing here is attached to the building.

The monitors plug into a socket and talk over wifi. Nothing gets mounted or wired in, so there is no landlord to ask and nothing to undo when you move out. The kit comes with you.
