Unless highlighted in the main product description, all of our Nordic Pure air filter range is disposable/single use. You may at first think reusable filters are the smart, ecofriendly way to manage your furnace filter requirements. The problem with many reusable filters is, they are less efficient at removing small potentially harm particles from the air, you will also need to step up your filter cleaning routine to ensure the filter works as intended, as soon as your see any wear or clogging you will need to replace it. Most users tended to clean their reusable filter with chemicals to try remove the dirt, the problem here is that the filter absorbs those chemicals and you then use the filter inside exposing yourself and others around you to potential harm.
