What is formaldehyde?

Formaldehyde is a chemical found in many furniture and home goods that poses health concerns if overexposure. Indoor formaldehyde limits have tightened due to its potential health risks, including respiratory irritation and suspected cancer. When buying furniture, one should look for products with low formaldehyde content and air rooms regularly to minimize the risk.

The formaldehyde test

Discover quickly and easily whether your furniture is contaminated with our Pollupatches formaldehyde test. If you have any concerns, we provide clear instructions for a safe and self-solving solution - without the expensive visit of an expert.

How it works

1. Distribute patches

Place the pollu patches in or on the places where you suspect sources of pollution.

2. Wait for reaction

Within 24-48 hours the green patches turn yellow or reddish if contaminants are present. If there are few or none, they remain green.

3. Evaluate & act

You can evaluate the test yourself using the simple color traffic light. The enclosed catalog of measures will then help you to act in a targeted manner.

"There have been three of us since January and at the beginning there was an unbelievable amount of things to consider when furnishing the children's room. I found out about harmful substances in furniture from a TV report and we also had a strange smell. It would be easy to get an expert It wasn't possible. We heard about the patches from a friend and tried them out. With the catalog of measures we finally got the problem under control and are now sleeping much better. :-)"


Pollupatches consist of a special bioplastic, which has large pores into which pollutants such as formaldehyde can penetrate. Inside the gel is a bio-indicator that is sensitive to formaldehyde. This reaction leads to the degradation of the green color and a color change towards yellow, orange and red. This color change is easily visible to the naked eye. 

No. The patches consist only of substances that are harmless to health. During development, care was taken to ensure that no hazardous substances, poisons or aggressive chemicals were used. 

However, the patch is not suitable for consumption and we advise keeping the patches out of the reach of animals and children. Also make sure to discard any patches after use.

The patches are made of biodegradable materials and can be easily disposed of with normal residual or organic waste. You can also crumble the patches after use and use them as biological fertilizer. 

Each test kit includes a positive and a negative control. This way you can be sure that the test kit works and that your results are meaningful. Each batch is extensively tested before it is released. Pollu patches are a guide that should help you to get an overview of possible sources of pollution quickly and easily. 
The patch is a good guide, if you are looking for verifiable evidence, we would be happy to advise you on the selection of special sensors and experts.

If you want to find out more about the sensitivity and reproducibility of the test methodology, you can request the data sheet here. 

Since June 2014, the EU has classified formaldehyde as “probably carcinogenic”. Due to the frequent occurrence in our everyday objects and materials, pollutants such as formaldehyde build up in our indoor spaces.

The search for the causes usually takes a long time and is expensive.
