Adults need at least seven hours of sleep each night to achieve the most significant health and wellbeing. To ensure that you’re sleeping soundly and refreshed for the day ahead, you must minimize distractions in your bedroom. An air purifier can help you breathe easier and stay comfortable for a sound sleep due to the ability to filter out harmful allergens and air particles that often keep us from falling asleep.

How Can an Air Purifier Improve Sleep?

The quality of both sleep and the air around you significantly affect your health. You’re at risk of illness and sleep disruptions if you spend your night inhaling dust, allergens, and harmful chemicals. Harmful air particles create difficulty breathing, inflammation, viruses, and many more symptoms.

If you’re wondering how to sleep better even if you’re in optimal health, one answer is an air purifier. An air purifier improves your sleep health by filtering out pollutants in the air, making it difficult to fall asleep and stay well-rested. The HEPA filter traps particles of all sizes to reduce allergens and bacteria, while activated carbon can adsorb odors and harmful chemical gases such as wildfire smoke.

To achieve deep sleep, you need to make sure that there’s no opportunity for any distractions in the middle of the night, so you’ll specifically want to find an air purifier that operates at a low decibel level or has a sleep mode. Many air purifiers offer you the multitude of benefits of sleep specifically. The best air purifiers for rest include soothing sounds and reduced allergy symptoms that help you fall asleep fast to achieve the recommended seven to eight hours of sleep you need each night.

In fact, air purifiers with pink noise — such as the Alen BreatheSmart 45i — help reduce distracting noises that interrupt your sleep, including loud talking or someone snoring. Pink noise instead provides low, relaxing background noise, helping you fall asleep faster and improving the depth of your sleep. Ultimately, this means you’ll get the necessary rest you need to feel rejuvenated and tackle the coming day.
