Yes, you can use our detergents in HE machines. Most washing machines in Europe are considered HE and our laundry detergents are developed for these appliances.
High efficiency (HE) washing machines are made to reduce the amount of water and energy used for each load of laundry, and they are also gentler on your clothes. In the EU, most washing machines are front-loaded, and this is the type of machine our detergents are developed and tested for (as well as hand-washing of course).
In the United and North America, traditional top-loading washers with agitators are still fairly common. If you are based in North America, high efficiency washing machines are usually marked with an HE symbol to differentiate them from traditional washers. Here’s a resource from the American Cleaning Institute that explains the difference.
High efficiency laundry detergents are safe to use in both traditional and HE washers. But it’s best to avoid using traditional (non-HE) detergents in HE washers, as these can produce an excess of suds which may hinder the performance of your appliance.
