How many square feet does a HEPA filter cover?

A HEPA filter is an air filter that can remove 99.97% of airborne particles that are 0.3 microns in size or larger. In order to achieve this level of filtration, HEPA filters must be made with very tight weave materials.

As a result, they are often used in environments where air quality is a concern, such as hospitals and cleanrooms. When it comes to the size of a HEPA filter, it depends on the specific model.

However, most HEPA filters are able to cover around 500 square feet of space. To ensure optimal performance, it is important to regularly replace HEPA filters according to the manufacturer’s instructions. By doing so, you can help to ensure that the air in your home or office is clean and free of harmful airborne particles.

What Size Air Purifier Do I Need?

In general, your air purifier’s CADR should be at least two-thirds of the total size of the room. A 15-foot-by-10-foot room, for example, has a 150-square-foot space. Because 2/3 of 150 equals 100, a smoke CADR of at least 100 is required for that room.

Benefits of Air Purifier for 800 Square Feet

There are many different benefits of having an air purifier with room coverage of 800 sq ft. If the area capacity is so high you can use these kinds of air purifiers in your living room or even your office. It will relieve all symptoms of asthma.

Since it is a large space there will be people that might smoke, you can put these kinds of air purifiers on in the room and have a healthy environment. Since there won’t be any small particles bothering you or floating in the air, you’ll have a fitful sleep.
