Pretty much everyone has seen dust floating around in their home, room or somewhere. And pretty much everyone would agree that if that dust is floating around, we're probably breathing some of it, right? Breathing dust with all of its' components (dirt, dust mites, mold spores, fibers, bacteria, etc) definitely makes allergy, asthma and respiratory symptoms worse for most people, so of course, filtering the air is a good idea to prevent that .
But did you know that dry air can cause not only sinus and airway irritation, but also makes the dust lighter and easier for it to circulate? That's right-dry air can actually increase pollution in a home or any indoor area. So other than using a good air purifier, another trick you can use to keep dust, allergies, asthma-and your indoor air quality – more under control is to use a quality room air purifier.
Why? Well, as we just described above, dry air increases the amount of dust and other allergens in the air, so adding a little moisture not only soothes dry nasal, sinus and respiratory tissues, but also makes those dust particles a little heavier so they don 't float around as well.
Most homes have dry air from time to time, and if you have a humidity meter or hygrometer, you'll probably notice that when the humidity drops to 25% or less, you've got more dust floating around-and your allergies, sneezing , coughing, all increase, too. How much moisture do you need? It's pretty simple-just set the humidifier to 35% and see how that goes first. If you notice a difference, leave it there for a while.
If you're still having about the same amount of symptoms, increase it to about 40 or 45%. That's usually about the maximum humidity you'll want for your home. It's enough to add soothing moisture and keep dust down, but not too much (above 55%) that would tend to feed mold or bacteria growth. Any wood furniture you have likes indoor humidity of around 45-55% too, so you'll keep them looking newer, less likely to have cracked finishes, as well, by using a humidifier.
So, while we do recommend that you filter the air in your home or room to remove as much dust as possible, we also recommend using a top-rated room humidifier to keep dry air from unwittingly causing you more problems and keep even more of that dust out of the air you're breathing every day.
