I purchased this new online, tried it out once, but the size was wrong, so I've kept it stored in a compression bag. 2019 model NU-201N Features a 6-hour automatic timer and dust mite removal function. Unused, operation confirmed, with instruction manual. Available for immediate purchase. Shipping costs apply due to the size, so no price reduction. (Shipping may be delayed during the New Year's holiday and due to weather conditions.)
