Hygienic attestation of WNL and WNL trolleys

We want our products to stand out on the market. 

Therefore, we pay attention to the added value to the products, their key features and strengths. One of the ways is to certify products, because certificates prove that the products marked with them are safe for human health and environmentally friendly, and that they have been checked by experts and positively assessed by them. 

By deciding on additional product approvals, we show that we care about high quality products. WNT and WNL tablet and laptop trolleys have been certified for a hygienic certificate and passed it with a positive result.


The hygienic certificate of the National Institute of Hygiene defines a product that does not have a negative impact on human health and the natural environment. It is issued by an institution authorized to assess quality - the National Institute of Public Health - National Institute of Hygiene (NIZP-PZH). It is one of the oldest research institutions in Poland, operating in the basic fields of public health. During certification, a given product is thoroughly analyzed in terms of chemical composition, mechanical properties and quality. In addition, it is subjected to a lot of research and testing. After meeting the standards and criteria, it obtains a certificate of the National Institute of Hygiene. 

Until recently, the PZH certificate was obligatory for most materials and devices used in the construction industry, as well as in water and air conditioning systems. Currently, from 01.01.2016, the regulations have been changed, so that the certificate is required only for a group of products that come into contact with water fit for human consumption. 

In other cases, it is not a mandatory document. These changes are intended to minimize water pollution and the harmful impact of substances released into its circulation. In the case of metal furniture, the PZH certificate is not obligatory, but our social responsibility for our products, sense of duty and concern for people's health and the safety of the natural environment made us apply for it. With a positive result 😊
