How should hospitals use air purifiers for COVID-19 protection? Since the start of the COVID-19 outbreak, hospitals have been under great pressure. Hospitals have turned to air purifier to create the safest environment to decrease virus spread and provide COVID-19 protection. Air purifiers are one of the important tools in the effort to improve hospital safety.
Can Air Purifiers Capture the Coronavirus?
Yes, and very well. Air purifiers that contain HEPA filters or even lower grade filters can capture virtually all sizes of solid particles, including particles 0.1 microns in diameter – or the same size as the coronavirus.
How to Choose the Right Hospital Air Purifier
It can be confusing to know which air purifier option is best for COVID-19 protection. Many companies use marketing gimmicks to trick you into buying an expensive, fancy air purifier that in reality do not give you any better virus filtration.
1) Are Medical Grade Air Purifiers Required For Hospitals?
No. Turns out, the term medical grade air purifiers are more of a marketing gimmick than anything else. Normal, HEPA filter air purifiers can filter viruses.

2) Are Air Purifiers with UV-light and Ionizers Needed?
These again are marketing gimmicks to get you to purchase a more expensive purifier. UV light air purifiers are too weak to kill viruses quick enough and can damage HEPA filters. Ionizers are also too weak to make a difference, and can produce harmful ozone.
3) HEPA Filter: The Golden Standard for Virus Filtration
The real key to an effective air purifier is the use of a HEPA filter, which can remove 99.9% of viruses from the air. Do not be fooled by extra unnecessary add-ons.
4) How to Choose the Best HEPA Air Purifier Model for a Hospital
In choosing an air purifier for a hospital, it is important to find an air purifier that can filter and circulate enough air for the size of the area. An air purifier’s CADR rating measures the amount of clean air it can purifier in a given amount of time. This CADR rating can be used to make appropriate calculations.
The CDC recommends 6-12 air changes per hour when dealing with viruses or other airborne infections. Therefore, the CADR rating (given in cubic feet per minute or cubic meters per hour) of the air purifier should be at least six times the volume of the hospital area being used in.
Smart Air’s no-nonsense air purifiers have been used in hospitals around the world to provide greater COVID-19 protection. Due to hospitals being larger and having a lot of air to clean, the powerful Blast is the typical purifier of choice for COVID-19 protection in hospitals. With a CADR of 890, the Blast is one of the most powerful purifiers on the market, cleaning large amounts of air per hour.
Below is a picture of hospital staff at the Philippine General Hospital. Most major hospitals in Manila, the capital of the Philippines, utilize the Blast for Coronavirus protection, as well as many hospitals around the world.
