Differences between a home humidifier and an air purifier

Humidifiers and home air purifiers made in the USA can impact the air you breathe in your home, but each of them serves a different purpose with unique benefits. Suppose you want your house free from allergies. In this case, you might be concerned with respiratory symptoms, dry air conditions, or you want to create a healthy home atmosphere for your kids and loved ones, you should understand the fundamental distinctions between an air purifier and a humidifier and how to manage each one most efficiently. The difference is that air purifiers clean the air, while humidifiers make the air damper when it’s too dry. At LakeAir, we help ensure our clients have no doubt and confusion when it comes to these differences between air purifiers and humidifiers. Some of our clients even wonder if an air purifier is the same as a humidifier. Well, we assure you it is not! Let us find out some variations between a humidifier and an air purifier.

The important things to know about both a Home air purifier and humidifier include the below factors:

  • How do both devices operate?

Illustration: Humidifiers boost humidity levels from 20% up to 40%. Will a humidifier help reduce allergies, or is it crucial to use an air purifier? However, we first need to understand the purpose behind a  humidifier and an air purifier. The significant distinction between the two devices is how they affect your indoor air quality:

Air purifiers are designed to enhance indoor air quality by removing air pollutants such as dust, pollen, smoke. On the other hand, humidifiers are made to refine indoor air quality by raising the humidity levels if too low. Fundamentally, air purifiers make the air fresh, and humidifiers make the atmosphere more humid. Let’s now find out a whole lot of consequences to this point.

A humidifier works differently from an air purifier. Humidifiers have no connection with indoor air pollution or air quality. As mentioned earlier, humidifiers only add wetness to dry air and are used in winters to help us fight the feeling of dry, musty air. In summers, most of us frequently enjoy air with normal 40-50% relative humidity levels. In the winter, notably, the humidity levels drop under 20% when the heating season starts. We know the effects of dry winter indoor air and feel the common symptoms of dry air like- sneezing, eye irritation, dry skin, and waking up with a dry mouth.

We have outlined a table below for your understanding; based on this, you can decide which air purifier or humidifier is better for your needs.
