Noise level

Vicks V745 will make some noise as all humidifiers do. On the low setting, it is quiet. You will hear a low boiling noise. On the high setting, you will also hear a boiling noise but a bit noisier. Sometimes it gets a bit talkative but that’s not happening often. If you are a light sleeper this unit will not wake you up.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one.

During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry.

I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
