Do you have a smoker in your house or a place that smells bad? You need to install an air purifier like dyson air purifier there. The closer the air purifier is to the pollutant, the faster it will trap the distressed particles. If your neighbors smoke and smell your house, place your air purifier near a vent or wall where the smell is most concentrated.

It is very difficult to capture the odors that do not leave the house, but by placing an air purifier where you take it home, you can trap the particles as close to the criminal as possible.

Covered area: the size and power of the air purifier determines the amount of space that can be covered. Some are ideal for office desks and bathrooms, while others clean the air in large basements. Our guide covers the whole range and it may make sense to purchase a few air purifiers for different purposes.

Particle size - Air particles (both good and bad) are measured in microns. According to the CDC, the most damaging air particles are .9 to .3 microns because they can pass through the human body's natural defense system and damage the lungs or invade the blood. Don't worry, all air purifiers can now filter 0.3 micron particles. These air purifiers help remove everything from smoke to pollen to house dust mites and even small particles that you don't notice.

Filtration System - All air purifiers use a unique multi-step process to purify the air. They are a little different, but I chose only the models that use HEPA (High Efficiency Particulate Air) filters. A fine mesh filter that traps unwanted particles and keeps the air clean. These filters generally need to be replaced every 6 months, but some advanced air purifiers have an indicator light that tells you when to replace them.

As you research air purifiers such as Levoit vital-100, you will see that CADR is mentioned in many places. But most people don't know what CADR stands for and what it means. CADR stands for Clean Air Delivery Rate and indicates the amount of clean air that an air purifier can deliver at maximum fan speed. A high CADR means that an air purifier can provide faster air purification.

CADR is measured by CMH (? / Hour) or CFM (cubic feet / min) and is 100? / Up to 500 from time to time? / Varies over time.
