Why affiliate ads: In the good old days, companies had to buy ads and cross their fingers that interested customers would see them. They spent a lot of money with no results. Affiliate ads are placed by relevant websites on their site for free. The company only pays the web publisher an advertising fee if someone makes a purchase. As you can imagine, this greatly reduces advertising costs for businesses. Smaller ad budgets means businesses can keep prices in check for customers. Receiving advertising fees helps websites cover the costs of running a website.

How we stay objective and without bias: Even though Diffuser Essentials uses affiliate advertising, it does not influence the objectivity of our reviews or the content on this site. Our #1 concern is to provide you with reliable diffusing information. We want to earn your trust as the best resource bar none. In order to do this, we only promote companies and products that we believe are the best, whether or not they have an affiliate program. Furthermore, by using Amazon as one of the main stores we link to, we can choose only the best products from their vast catalog of items without bias.

Diffuser Essentials is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to

Product reviews:  I encourage users of this site to contribute their constructive reviews of any diffuser they have used. If you represent a diffuser model, you may contact me about having your product reviewed on this site using the contact form. Any diffusers received by this site will be disclosed as such and will not influence the objectivity of the review.
