Air purifiers are the solution to this. But can a home air purifier help you sleep better? The answer is yes—here’s how. 

The Connection Between Air Quality and Sleep 

Your body is very sensitive to the quality of the air you breathe, particularly at night while you are in a passive state for 6 – 8 hours. Dusty homes, pet dander, pollen, mold, and even volatile organic compounds (VOCs) can pose respiratory challenges, causing irritation, congestion, or triggering allergies. They never rise to your level of consciousness, but they can disturb your ability to drop into deep, restful sleep. 

Studies have found that clean air helps improve sleep quality. Exposure to higher levels of air pollution was associated with a greater likelihood of poor sleep efficiency in a study published in the American Journal of Respiratory and Critical Care Medicine. That's were choosing the best small air purifier for home becomes necessary for fostering an environment ideal for better sleep. 

How A Home Air Purifier Can Help You Sleep Better 

Reduces Allergens and Irritants 

Air purifiers with HEPA filters can trap at least 99.97% of airborne particles, including dust, pollen, mold and pet dander. And because these are all common allergens, they can lead to sneezing, coughing, itchy eyes, and postnasal drip — all of which can ruin a good night of sleep. By removing these irritants, air purifiers assist you in breathing more easily and sleeping more comfortably throughout the night.

Odors from cooking, pets or even musty bedding can disrupt sleep. Air purifiers that included activated carbon materials work to pull in these odors, resulting in a cleaner, fresher, and more inviting sleeping environment. A room that smells clean might not make you pass out, but it helps you relax.

Higher-end air purifiers might deploy UV-C light or ionization to kill pathogens that are floating around. This doesn’t stand in for handwashing or other hygiene practices, but can help minimize viral load in the air, which can be especially beneficial during flu season or in homes with immunocompromised people.
