A lung health and allergy specialist on the air purifier he swears by for his own allergies

Lung health and allergy specialist Dr. Noah Greenspan knows well how much allergies can impact your life — and how important sleep is for overall health. Here’s the air purifier he recommends for easier breathing and better rest overnight.

Dr. Noah Greenspan knows well how much allergies can impact your life. After all, it’s literally his job: As a board-certified clinical specialist in cardiovascular and pulmonary physical therapy,  a lot of his work involves helping patients understand how their environment can set off allergy triggers. 

He takes his own medicine too: Greenspan sets up optimal conditions for a good night’s sleep at home by sleeping with an air purifier running gently in the background. The BlueAir Blue Pure 311i Max + SmokeBlock Filter air purifier is his go-to for managing allergies, so it’s easy breathing all night long before his next day of clinical work. 

Given that it’s about to be peak ragweed season, we’re inclined to pay attention to his recommendation. Keep reading to find out why he recommends the BlueAir air purifier, then shop it yourself below.

“Allergies play a massive role in lung health,” says Greenspan. “A lot of triggers and allergens affect people with respiratory disease. It’s all connected as far as air quality both indoors and outdoors goes. The worse the air quality, the worse it’s going to be for someone with allergies — or even without allergies in some cases.”

How allergens get in our homes 

“The idea is we want to keep the home environment as trigger-free as possible,” he says. 

"So, you go out to work all day and depending upon what your job is, you're going to have more or less exposure to various allergens and triggers. All that stuff falls all over your body, your face, and your nose. Then, when you come home and lie down in your bed or sit down on your couch, that's there.

"And then the next day if you don't clean it, it doubles. These things can kind of build up and we can reach a tipping point to where they become really uncomfortable for us. That means you're going to be breathing it into your lungs, blowing it out of your lungs. It's going to be all over.”

How to reduce allergens indoors 

Since we move about our homes making dinners, playing with pets (dander!), wrangling our kids, and stretching out to watch Netflix, there’s little we can do about what we shed. And while maintenance cleaning is important to avoid buildup, it’s impossible to keep everything completely clean all the time (and do we want to live that life?). 

"I think if you do have a problem with allergies, have at least one space in your home that's kind of like a clean space, like that's going to be smaller and therefore easier to control the air quality,” Greenspan says. "Let's have an air filter in the bedroom. And let's keep that space as kind of hermetically sealed, if you will. Not really hermetically sealed, but think about what you're bringing in and out."
