The arrival of spring can bring on some of the most miserable symptoms for the allergy-prone, and for many, there’s no relief to be had indoors. Predictably, our homes are their own source of potentially troublesome allergens (like dust mites and pet dander), plus, without trying, we’re constantly tracking outdoor allergens (like pollen and molds) into the house with us on our clothing, shoes, and even in our hair.

The allergy epidemic—many sources say allergies affect a growing third of the population—doesn’t appear to be slowing down. 

We asked Chitra Dinakar, M.D.—Clinical Professor of Medicine at the Stanford University School of Medicine and Gies Endowed Faculty Scholar at the Sean N. Parker Center for Allergy and Asthma Research (the Rolls Royce of allergy research centers)—to help us put together a guide for an at-home allergy detox. We were particularly curious about her clinical opinion on air purifiers, which many allergy sufferers report to be helpful. (One goop staffer, whose allergist recommended she get a Dyson purifier after an allergy prick test revealed she was essentially allergic to all of the blooming plants and trees in NYC, has been significantly happier since. The Dyson purifier uses a HEPA filter, which, as Dinakar explains, is designed to capture small particles, like animal allergens and mold spores.) Below, our interview with Dinakar, and a room-by-room allergy-proofing checklist based on her expertise. (If food allergies are a concern, too, see this piece with Dinakar’s colleague, Sharon Chinthrajah, M.D.)
