Review: Best Ultrasonic Humidifier - I purchased a Pure Guardian Ultrasonic Humidifier in early 2019 because of the winters and dry heat causing my skin to be super dry and my nasal passages to bleed. The one I purchased then was manual and I keep it in the bedroom. Since it worked great, I wanted one for the living room so I didn't need to keep moving the first one I purchased. This Pure Guardian H4750AR Ultrasonic Cool Mist Humidifier is push button and has the cool mist only, which is totally fine. desertcart had the lowest price and I thought I would try it out to see if it was worth it. This definitely is! If you are looking for a larger capacity cool mist humidifier that is ultrasonic (meaning it does not need filters and gives an even mist) then this is a great purchase. I have been using it for almost a week and it runs all day and night. I fill it up and keep it on the highest setting. It is really quiet and as I stated, it is a nice fine mist. The Pure Guardian are definitely great products. The manual states it comes with a 3 year warranty. Review: Phenomenal! - This humidifier has been a game changer. It's easy to use, easy to clean, but best of all it is powerful enough to humidify our entire apartment. I refill the tank every other night but keep it running round the clock. As a singer, it has made warming up and maintaining my vocal health so much easier. I didn't realizer how helpful it would be. My boyfriend struggle with painfully dry skin in the winter and it has even helped him!! I did a lot of research before purchasing and I am so happy with my choice!! ## Features - COOL MIST HUMIDIFIER: The PureGuardian H4750AR ultrasonic cool mist humidifier guards against dry air in the home, perfect for those with and dry skin.

I did a lot of research before purchasing and I am so happy with my choice!! ### ⭐⭐⭐⭐ Works great but can be improved *by G***N on January 4, 2022* I use this device often. It works best with distilled water, or reverse osmosis water, otherwise it creates white dust in the room. I wish there was a better way to adjust low, medium and high output to my preferred preference, not just the setting on the machine. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/104242064-pure-guardian-h4750ar-ultrasonic-cool-mist-humidifier-120-hrs-run](https://www.desertcart.tn/products/104242064-pure-guardian-h4750ar-ultrasonic-cool-mist-humidifier-120-hrs-run) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-19*
