# Your Cold and Flu Season Home Kit

> The home health tools that help you monitor and stay comfortable through cold and flu season — thermometer, pulse oximeter, air purifier, and nebulizer — and when to seek care.

When respiratory bugs are circulating, a few home tools help you keep tabs on how you or your family are doing and stay more comfortable. None of them diagnose illness — but they make it easier to monitor and to know when something needs a doctor.

<Warning>
  Home tools support monitoring, not diagnosis. Seek care for trouble breathing, a low oxygen reading, a high or persistent fever, or symptoms that worsen quickly — and call 911 for severe breathing difficulty.
</Warning>

## What's the most useful tool to have on hand?

A fast, reliable **thermometer** is the cornerstone — it tells you whether there's a fever and lets you track it. For a baby under 3 months, any fever of 100.4°F (38°C) or higher is urgent. See [when to worry about a fever in adults](/thermometer/when-to-worry-fever-adults) and the [fever in children guide](/thermometer/fever-in-children-guide).

## Should I check oxygen levels when sick?

A fingertip [pulse oximeter](/pulse-oximeter/overview) can spot-check your blood-oxygen level during a respiratory illness and sometimes flags a low reading before you feel very short of breath — see [oxygen during respiratory illness](/pulse-oximeter/oxygen-during-respiratory-illness). Watch the trend, weigh it against how you feel, and seek care for a persistently low reading or real breathing difficulty.

## Can an air purifier help during cold and flu season?

A HEPA [air purifier](/air-purifier/colds-flu-viruses) reduces airborne particles indoors, which can help with comfort and indoor air quality when windows stay shut. SonoHealth's **AirPro** pairs HEPA 14 filtration with a sealed UV-C stage. It's a supportive measure, not infection protection on its own.

## What if someone has asthma or COPD?

Respiratory infections can trigger flares in people with asthma or COPD. If a doctor has prescribed nebulizer treatments, a quiet, quick [mesh nebulizer](/nebulizer/overview) helps deliver them at home. Follow your action plan, and don't wait on a worsening flare. See [respiratory health at home](/guides/respiratory-health-at-home).

## What's a sensible cold-and-flu kit?

A practical set: a **ThermoPRO** thermometer, a fingertip **Pulse Oximeter**, and an **AirPro** purifier — plus a prescribed **MistPro** nebulizer for those who need it. Add rest, fluids, and over-the-counter remedies used as directed. Browse the range at [SonoHealth.com](https://sonohealth.com/shop/).
