Choosing the Best Air Purifier Humidifier Unit
How Long Do I Need It For?
Environmental factors also play a role in choosing a humidifier. Living in a tropical climate with high humidity levels, you don’t need a high powered humidifier. In fact, a dehumidifier would be more appropriate in the tropics. Meanwhile, people living in places with a dry climate and harsh winters need a high powered humidifier that can run non-stop.
What Size Humidifier Do I Need?
Generally speaking, the smaller the unit, the smaller the capacity. Tabletop humidifiers are great for small rooms and offices, while the larger ones are ideal for large open spaces. Manufacturers usually explain what room size can their purifier and humidifier serve.
What Kind of Air Purification Do I Need?
True HEPA filters clean out even the smallest allergens and particles down to 0.3 microns. If you want to combat smell in the room, look for carbon filters that absorb odor and VOCs. Ionizers in air purifiers capture particles and reduce static in the space, while UV purifiers kill germs, mold, and bacteria.
Is the Purifier & Humidifier Noisy?
Look for low-noise models that guarantee to keep their noise levels at 40 dB or lower. Keeping in mind that 40 dB is the sound you can hear in a quiet library, you won’t have trouble ignoring it. If you’re sound sensitive, don’t worry, some of our chosen models have noise output as low as 19 dB!
FAQ
What is the difference between an air purifier and a humidifier?
A humidifier increases the level of moisture in the air by adding fine water droplets. It helps keep your skin from over-drying and your breathing comfortable. It’s beneficial in drier conditions or in spaces with air-conditioning.
An air purifier cleans the air by capturing and removing airborne particles, allergens, viruses, and in some cases killing germs and bacteria. It caters to your health by ensuring cleaner air.
Can you use a humidifier and air purifier at the same time?
You can use two separate units simultaneously; they just need to be far apart because some components in air purifiers can weaken if exposed to high humidity. But if used separately, they don’t give out the same effect. Air needs to get purified before the humidification process. If used independently, you will be breathing humidified air that might not have been cleaned or vice versa.
