Great quality air purifier. Looks really nice and runs so quietly you won't notice it's on. Ideal for large room - filtering outside allergens, bad smells, dust and smoke in the home. SUPER east to use. Has cute indicator light. Only used 3 months. Works perfectly. Filter should probably be replaced in about 3 more give or take... Moved and don't need it anymore. Comes with one Prefilter cover in grey.
