Air Purifiers Vs Humidifiers: Working DIfference

Air Purifier:

As the name suggests, Air Purifier improves indoor air quality by removing unwanted dust particles or airborne contaminants with air filters. Basic Air cleaner helps remove a range of particles such as dust particles, bacterias, and some high-quality ones can also remove the smoke odor (cigarette or any other) and allergens.

If we talk about the internal working, the air purifier sucks air from the indoor surrounding through the filters’ array into the air purifier machine just like an air conditioner and then release back the fresh air into the environment.

An air purifier with a HEPA filter is the most popular and certified efficiency in trapping 99.97% of particles at 0.3 microns (pollen, pet dander, dust mites, tobacco smoke, etc.) without altering or adding anything to the air.

However, many other filtration techniques are used in domestic or residential air purifiers like PlasmaWave technology, activated carbon, ionization, electrostatic precipitation (ESP), and photocatalytic oxidation (PCO), ozone generation, and others.

HEPA filters air purifiers are entirely safe to use at home as they don’t emit ozone or other harmful byproducts.

Humidifier:

As you can quickly tell from the name, a humidifier adds water vapor to the air by pumping moisture into your room. Air becomes cool and fine mist before discharging it into the atmosphere.

Moreover, to keep the humidifier operate properly, you need to replace the reservoir with cold water from time to time. It is the main feature of a humidifier that makes it a must-have device or machine in arid and hot areas because the humidifier is portable and cools and moisturizes the hot air.

You can also use humidifiers in the winters by adding hot water to the reservoir and discharge the warm mist into the air. Plus, making the air cool or warm, a humidifier can help provide relief from nosebleed, sinus issues, minor breathing problems, and dry skin issues.

But make sure you are not overusing the humidifier because it increases the humidity level of the room. If you already have a wet room and use a humidifier, it can promote mold growth.

The perfect operating humidity level for a humidifier is 30 % to 50 %. Below 30% is too dry and over 50% humidity can encourage dust mite reproduction and mildew.

However, you can use both together, but you need to keep them away from each other not too close. Otherwise, the air purifier filter may get jammed due to moisture from the humidifier water vapors.
