Refresh the air naturally in your home, office or spa using the advanced ultrasonic technology of PureSpa Deluxe. With whisper-quiet operation, PureSpa Deluxe runs softly in the background so it does not disturb the peace of the room. By distributing a gentle, cool mist into the air, PureSpa Deluxe also functions as a moisturizing humidifier for dry rooms. The large capacity water tank allows you to run PureSpa Deluxe for 8-10 hours without the need for excessive refills. When water runs low, the automatic shutoff feature conveniently turns PureSpa Deluxe off for you. Adding 3 to 5 drops of certain 100% all-natural essential oils (not included) to the water tank of your PureSpa Deluxe can help create a more comfortable atmosphere for people suffering from a cold, nasal congestion, allergies, asthma and more. PureSpa is BPA-free and backed by Pure Enrichment’s industry-leading 2 Year Warranty so your satisfaction is guaranteed.
