Rated 5 out of 5 by from Great diffuser, great price I am delighted with my diffuser. Having searched for one for months I came across this one in a review by the Independent. It’s a good size and very effective. It also comes with 2 small complimentary bottles of essential oils which is a nice touch. Do not be tempted to use more than the 5-7 drops recommend as I did! That’s more than enough for the machine to be effective. This is a great diffuser.

Rated 5 out of 5 by from Great Diffuser Does exactly what I needed it to do. Anyone debating this over an Amazon special should just get one of these, much better quality and your room doesn't get soaked during the use of it! Love the 30 seconds on, 30 seconds off feature too

Rated 5 out of 5 by from Lovely Diffuser - Highly recommended. I wanted to try something out that would add some ambience to my living area in the house and provide an alternative to candles. This is just the item. Powered by mains supply, this diffuser can be used with various oils. I tried the peppermint oil, which was quite nice, although I'm looking forward to seeing what else is available. The other great feature is the coloured lighting. This can be used with the oils or without. It’s personal preference. This item is great to help relax after a busy day.

Rated 5 out of 5 by from Homedics Dream for a dreamy atmosphere The Homedics Dream is very light and minimal Air Diffuser that vaporizes essential oils and has two functions in one. It works as an air diffuser with ultrasonic technology, as well as combined with the ambient light mode. It's extremely simple to use and to clean and works with Homedics pure essential oils or the one of one's choice. I've been using it for less than a month and I'm loving the relaxed atmosphere it creates in seconds. I usually use the combined function. It starts switching lightly and becomes blue, green, yellow, orange and magenta while vaporizing a scented mist. It does a watery, bubbling sound while in action but I don't mind it and I find it really relaxing. The only downside is that while Homedics Dream becomes a nice of furniture, the cable on sight isn't really nice. I suggest to use more drops of pure oils comparate to the recommendation as after 4 hours of usage without stops, I couldn't feel my scent. The orange oil by Homedics is purely awesome! I would grade it 4 and a half.

Rated 5 out of 5 by from Great for relaxation and calming I decided to try this product as my young daughter deals with severe anxiety. It came with two sample oils (orange and peppermint) and I have also used Olbas and our all time fave, lavender. It is very simple to use, the mood lighting adds an additional calming environment. Instructions are clear and product is very simple to use. My daughter and I both love it and would very highly recommend it. Perfect 5 out of 5 score for a review.

Q & A

The light is working on my diffuser but the steam doesn't work. There's sufficient water. Any ideas?

Asked by: Anna H
We recommend cleaning the water reservoir with a 50/50 vinegar and water solution and a soft bristle brush. Pour a 50/50 mixture of vinegar and water into the reservoir, then soak for five minutes. Brush reservoir walls, base, and ultrasonic membrane clean with a soft-bristle brush and rinse. NEVER touch the ultrasonic membrane with your fingers, as the natural oils in skin can damage the membrane. After cleaning the reservoir, fill the reservoir with water to the “max” fill line inside the reservoir.

The wire is exposed next to the plug of my humidifier. Is there somewhere I can buy a replacement plug?

Asked by: Saraht
Dear Saraht, You can buy a generic adapter from Amazon, eBay or the most reputable electronics stores by following the technical specifications located on the sticker on your diffuser. Kind regards, Team Homedics

Can you specify how many square feet can it cover?

Asked by: Giedre
Dear Giedre, There are many different factors with regard to the area an aroma diffuser will cover, such as the quality of the oil and the number of drops used. However, in general using our oils and 6 drops per 100ml of water, it will cover an area up to 500 squared feet. If you have an area larger than this and require a strong scent, we would recommend that you use 2 diffusers. Kind regards, Team Homedics

Hi, I have the Model: ARMH-220WT-WW, which I’ve been using for couple of days and it is noisy, a humming comes from the unit, which is distracting when sitting quietly or if I’m going to use it in the bedroom. Any suggestions please?

What materials is this diffuser made of? What is the chamber made of? Clear descriptions of the materials your diffusers are made with would be helpful, as they are very attractive designs, but find It offputting when the materials arent described! Thxs

Asked by: Vicky01
Dear Vicky01, Most of the parts are made from either ABS or PP plastic. Kind regards, HoMedics Team

Please could you confirm if this can be used with different brands of oil? Thank you

Asked by: LA86
Dear LA86, Yes, we only recommend the use of essential oils which are made from natural plant based extracts in our aroma diffusers. Do not use oils for reed diffusers: they are generally chemically created scents and are not suitable for use in these products. Kind regards, Team Homedics
