This type of purifier is known to eliminate 99.97% of most airborne allergens with size 0.3 microns and bigger.

2. What Should be the Size of Your Air Purifier?
Air purifiers are categorized into four sizes:
- Small Air Purifier – This is intended for personal space or room that is up to 299 sq. ft.
- Medium Air Purifier – This is designed for areas between 300 and 699 sq. ft.

When choosing the size of the air purifier, the first factor you need to consider is the area of the room. To calculate the sq. ft., measure the width and length of the area in feet and then multiply the two numbers. Then find an air purifier based on the sq. ft. you have computed.
For those with asthma or allergies, it is best to look for an air purifier with an air change rate per hour or ACH rate. The figure is equivalent to the number of times the machine can filter the air in an hour. An air purifier that can clean the area at least four times per hour is the right choice.
3. Consider 3 Air Purifier Key features
Before purchasing an air purifier, there are things you need to consider. With the present technologies, purifiers are mode advanced these days. Here are the features you need to focus on:

The larger the HEPA filter, the more particles will be removed. The material, construction, and size of the filter determine the machine’s performance.
- Activated Carbon Filters – This type of filter is used along with other filters. This filter helps in absorbing gases and odors, thus neutralizing chemicals, fumes, smoke, and food smell.

#3 CADR Ratings
The CADR is the measurement of the purified air delivered by the machine at its optimum speed setting. It is to measure the amount of particle and airflow removal efficiency. The higher the CADR, the more efficient it will be.
4. Where to Position Your Air Purifier?
