Disclaimer

Last updated 2 September 2026. This page describes how this shop works in plain English. It is not legal advice.

What this site is

The guides here are general information about indoor air, ventilation and the products we sell. They are not professional advice about your building, your workplace, your health or your legal position.

For anything that matters, take advice from someone qualified: a ventilation or HVAC engineer for a building, an occupational health professional for a workplace, a doctor for anything about your health, and a lawyer for a question about your obligations.

What the products do

A CO2 monitor measures carbon dioxide, temperature and humidity. It is a gauge of how well a room is ventilated. It does not detect carbon monoxide, smoke, particulates, volatile organic compounds or any other gas, and it is not a safety device or a medical device. Fit a carbon monoxide alarm and a smoke alarm separately if you need them.

The ozone machines are odour treatment units used in a room with nobody in it. A humidifier adds moisture to a room. The UV lamp emits UV-C light. The sprayer mists whatever liquid you put in it.

What we do not claim

• We make no health, medical, respiratory, sleep or productivity claim for any product.
• We publish no efficacy figure, kill rate or percentage for the ozone machines, the UV lamp or the sprayer.
• We publish no accuracy tolerance or calibration figure for the monitors, because none is published for them.
• We publish no filtration or protection standard for the face mask or the visor, because none is published for them.
• We publish no star ratings or reviews on product pages.
