How to pick the best air purifier for an open floor plan?

Picking a good air purifier can be a hard task. If you need to get one, there are basic features you need to consider first. But you do not need to stress up analyzing these factors, we will help you make a good choice for your open floor.

1.  Coverage

Most air purifiers come with coverage capacities. It is important you get a model that is rated for large to fit your open floor. This means that you will have your open floor cleansed faster with ease and it can also be filtered even on the purifier’s lowest speed.

2.  Noise levels

It is inconvenient having to bear the noises in instances when you want to rest. Noise levels of the air purifier make a very important factor for  choosing a good air purifier for an open floor plan.

3.  True HEPA filter

A High Efficiency Particulate Air (HEPA) filter is also necessary. An air purifier with a HEPA filter can trap 99.97 percent of particulates as small as 0.3 microns or larger. This can be important in purifying the air for your open floor plan. 

4.  Stages of Filtration 

Different models with different filtration stages ranging from 2 up to 5. The more the stages of filtration, the better the purifier is at removing different airborne particles. For an average open floor plan, an air purifier with 3 stages of purification is good.  

Does size of an air purifier matter for an open floor plan 

Not really, the size of an air purifier does not make a difference. You only have to focus on the area coverage of an air purifier. There are numerous big air purifiers with an area coverage of less than 500 square feet. Also, there are those with an average size but cover more than 500 square feet.  Buying a big air purifier that does not cleanse a wider area can turn out to be a total wastage of money. 

How many air purifiers would I need for an open floor plan?

The number of air purifiers that is perfect for an open floor plan depends on the size. If your open space floor is about 1000- square feet, and you intend to buy an air purifier with space coverage of 520, you will need two of them. So, it is advisable to understand the size of the floor plan, to determine the number of air purifiers you need. 

What is the best location for an air purifier in an open floor plan?

You probably know your room more than anyone else. So you best understand the sources of air pollutants in this room. To make full use of your air purifier, it is important to place it next to the source of pollution. You cannot place the purifier at the extreme end, yet the source of pollution is on the extreme opposite side. 

How will an open floor plan affect the overall air quality of my home?

Open floor plans can really affect the overall air quality of your home. When cooking, it is easy for the odors to cover up the whole home. Moreover, when someone smokes, the air quality in the home is affected. This is because there are no partitions to lock out or prevent the airborne pollution.
