The air you breathe could cause certain health conditions, such as allergies and other respiratory issues. So, it makes sense to look into ways to improve the air quality, especially in your home. Using room air purifiers could help, as they are designed to sanitize the air, which could come with toxins, allergens, and pollutants. They are different from humidifiers and oil diffusers, which add particles to your indoor air. Likewise, they are different from regular filters, which act only to eliminate particles, as purifiers are also capable of sanitizing them.
