## Features

- SIMPLE, FAST and ECONOMIC way to determine whether Formaldehyde Gas (HCHO) is present in your home environment. This test kit is suitable for all living areas up to 270 square ft. (25 square meters). One kit per one room/item, if you would like to inspect your entire house we recommend buying the same amount as the room quantity. Better air quality – healthier family.
- NOTE: The longer the test area kept closed before measuring formaldehyde the more reliable results you get. Example: if you close the room for 8 hours and turn off all ventilation, air purifiers or anything that can affect the air than after measuring Formaldehyde you will get results of what the concentration is for such conditions. (Possible scenario: what is the formaldehyde concentration during 8 hours sleep with all windows closed).
- Six easy and well-explained steps with English manual will give you trustworthy results in 30-50 minutes time. Please keep the air temperature and humidity unchanged as much as possible during the test.
- This test will provide only visual results of what is the concentration of Formaldehyde in the room and should only be used for home or office environment and not compared to industrial equipment. If Formaldehyde Gas is present in your environment we recommend purchasing an air purifier or any other Formaldehyde removal technology to protect yourself and family. Since long-term exposure to Formaldehyde can cause serious health problems.
