Buying Guide Stats

Fragrances play a very important role in your home. They not only make your place smell alive but can be very psychological beneficial. You may not notice it but they sure do calm and relax you down.

As you may have heard, listening to music can improve your mood, as does being around pleasant fragrances. It has been scientifically proven as well.

The best way to spread fragrance is by using an essential oil diffuser. A diffuser is a perfect way to get aromatherapy. An oil diffuser is a small, electronic device that vaporizes the essential oil fragrances you put in it.

You can use your favourite essential oils, be it lavender oil or any other fragrant oils. It diffuses oils and provides a subtle scent. The steam vapour can also provide many health benefits.

Looking to get one you’ve come to the right place. However, let’s first start by understanding the factors one must consider before choosing an oil diffuser.

Diffuser buying guide: How to choose the best diffuser

Here are some key factors you should look at before choosing the right essential oil diffuser for your home.

1. Coverage area

It is important to know the area span of the diffuser. Distributing the oil`s fragrance throughout the room should be the main role of the diffuser. However, do read and understand if the oil diffuser can provide you with that.

Make sure to read the coverage area of the diffuser mentioned in units. That would give a better understanding of how big a room can be covered by it. The aromatherapy diffuser requires a moderate coverage area.

2. Running time

There are different running time durations for every diffuser. Some diffusers will allow you to control the diffusion and help you save the essential oil. However, some diffusers have their intervals set.

3. Size

Size matters the most. No one would want a diffuser covering a large spot in the room. However, the size can give a better idea of the area the unit is going to be taken.

Small diffusers are best in portability. Moving them from room to room gets easy and convenient for you. If it is a moderate size diffuser you can also take it with you if you are planning to travel.

4. Essential oils and water reservoir capacity

Diffusers are available with 1ml to 260ml water and essential oils capacity. It depends on how long you want the diffuser to work. If you plan to use a diffuser throughout the entire day, then you surely wouldn’t want the 1ml reservoir size unit.

However, the greater the reservoir capacity means the bigger diffuser. Many people like to get small, cute diffusers to blend with the room décor.

Frequently asked questions

You may just see a mist coming out but inhaling the mist can be beneficial depending on the essential oils you use.

Diffusers are best for aromatherapy vapours. They are long-lasting and emit natural fragrances throughout the entire room. You can keep the diffuser on and it may help you sleep better and guarantee a deep sleep.

Using natural essential oils can be safe. However, if you are allergic to some fragrances it would be better if you only use the essential oils which are fine with you.

Diffusers can be a safer option than candles as there is no burning flame in the room. However, both have their benefits.
