FORMISENSE™ is a handheld formaldehyde detector and indoor air quality monitor for home use. It reads formaldehyde (HCHO), TVOC, PM1.0, PM2.5, PM10, temperature and humidity, and shows all seven on one LCD screen. No app is needed to see your readings.
Why people buy it
Most people start looking for a formaldehyde detector after something in the house changes: new furniture, a new mattress, fresh paint, new flooring or a move into a newly built home. EPA names pressed-wood products such as particleboard, hardwood plywood and medium-density fiberboard as likely the biggest formaldehyde sources in homes. You can’t see formaldehyde, and a fading “new furniture” smell doesn’t tell you the concentration. FORMISENSE gives you a number.
Because it’s handheld, one monitor can check the bedroom, then the nursery, then the home office. Compare the readings, air out the rooms that read higher, and check again.
What it measures
- Formaldehyde (HCHO), 0.000 to 1.99 mg/m³, electrochemical sensor per the supplied specifications
- TVOC (total volatile organic compounds), an overall reading rather than a list of individual chemicals
- PM1.0, PM2.5 and PM10 particulate matter
- Temperature and relative humidity
How to use it
Charge it over USB Type-C (about 4 hours for a full charge). Switch it on in the room you want to check, keep airflow around the unit clear, and let the readings settle as described in the instructions. Note the numbers, then move to the next room.
For context, the World Health Organization’s indoor guideline for formaldehyde is 0.1 mg/m³ over any 30-minute period. FORMISENSE is a consumer monitor that gives indicative readings. If a reading worries you, or you need a certified result, book a professional or laboratory air test.
