Allergies. The sniffling, sneezing, itchy, watery eyes or the scratchy, full throat that you can’t seem to get clear. Chances are you, or someone you love has dealt with allergies, either seasonally or regularly. Allergies are caused when our immune systems identify a particular allergen as harmful, even though it’s not, and produces antibodies to fight it. The reaction can cause inflammation in your skin, sinuses, or airways and produce unwanted and irritating symptoms that come with allergy triggers.

There’s no magic bullet to make your allergy problems disappear. But there are ways to help alleviate them – and air purifiers definitely fall into that category. Air purifiers are designed to pull the smallest particles out of the air, capture them in the filter, and push clean air back out into your living space. Mold spores, pet dander, dust, smoke – and so many other things that irritate allergies can be filtered out of your home with an air purifier. It’s an easy and effective way to help you breathe easier.

One of the places in your home you may encounter the most significant allergy issues is your bedroom. We spend six to eight hours or more in our bedrooms every night – so there is plenty of time for irritants to cause itchy, watery eyes, sneezing, and sniffling. Dust mites can live in your bedding and carpet.

What to Look for in an Air Purifier for Your Bedroom

There are a few things to look for when purchasing an air purifier for your bedroom. Make sure that it works for your space. All air purifiers have a maximum square footage they cover. If you put it in a room bigger than the maximum square footage coverage area, it won’t work effectively. Also, look for the type of irritants the purifier traps. You will want one that works for your particular allergy triggers, as well as other airborne particles that can cause you and your family issues.

Air Purifiers and Allergies

It doesn’t matter how much cleaning you do; you’ll never be able to get rid of all the dust, dander, and pollen in your home. If allergies are an issue for you or anyone in your family, an air purifier is a substantial investment that can help you rest and breath better.
