Before talking about the best air purifier for open floor plan, there is a question that needs to be addressed; is air purification necessary? Yes, it is. Air is a vital necessity for human existence, but sadly our daily activities keep contaminating atmospheric air on a high scale; hence, there is the need to improve indoor air quality using an air purifier. An air purifier or air cleaner is a device that removes contaminants from the air in a room to improve indoor air quality.

There are several air purifiers best suited for different purposes; there is best air purifier for loft, best air purifier for high ceiling, best air purifier for open space and there are also best for air purifier for multiple rooms. For this review, however, we will discuss the best air purifier majorly for open floor plan.

Air purification in an open floor plan – what to know

Talking about air purification in an open floor plan, let’s shed light on what an open floor plan is. An open floor plan is a term used in architectural and interior design for any floor plan that uses large, open spaces and minimizes the use of small, enclosed rooms such as personal offices.

An air purifier for any open floor plan, be it high ceiling, open space, loft, or multiple rooms, is meant to remove all harmful elements from the air while keeping the “normal” elements.

Purification in an open floor plan and generally depends on the kind of pollutant. There are different kinds of air pollutants; thus, different air purifiers are designed to remove most if not all the contaminants in the air.

Particulate matter present in the air are made up of large elements and are best removed when pushed through a HEPA filter.

Chemical pollutants, however, are smaller. This makes trapping them through a physical filter difficult; thus, they are removed/absorbed by a molecular sieve.

Can an air purifier be too big for a room?

Yes, the capacity of an air purifier or the square footage rating should not be too much for a room so as to ensure adequate functionality, although it being too big has no negative effect. Besides, having a large air purifier in a small room is highly unnecessary and might also be a waste of money. So it’s better to size the room and know the best air purifier for it.

Will a small sized air purifier works for open floor space

The best answer to this question is that one has to match the capacity of an air purifier to the size of the space it will be installed. Buying a purifier that is too small for an enclosed space can turn out to be a waste of money. So, the best air purifier for the purpose intended should always be considered.
