Most of you knows that original cabin filter for Niva does not exist. There are many options of filters to install but the one we offer is the best and the most effective. Comparing to what others sell - this is the only one which allows to fully close the cover. Some small modifications are required (please see photos) - but it's worth it. We could sell the filters which all the rest offer but we simply do not want to offer you palliative/semi-solution.
