In this post, we’ll show you how to determine the proper size you need for an air purifier to work most effectively inside your home.
This is an essential step when going through the process of deciding how to choose an air purifier that’s right for your needs.
First, Determine Where You Want to Place the Air Purifier
The most important factor when sizing an air purifier for your needs is to first determine where you want to place it.
Are you looking to purify the air within a single room, multiple rooms or an entire house?
The answer to that question will help narrow down the optimal product choice for your application.
Next, Measure the Square Footage
After making this decision, the next step is to figure out what the square footage is for the space you want to purify.
If it is a single room, this step is quite easy. All you have to do is use a measuring tape to take measurements of the two perpendicular walls. This will allow you to determine the square footage for the room.
If you want an air purifier that will cleanse the air for multiple connected rooms, just type in the length and width of each room separately, then tall up the results. For example, if we also wanted to add an adjoining room to our previous example, 120 sq. ft. and this other room measures 80 sq. ft., the total square footage would be 120 + 80 = 200 sq. ft.
If you’re trying to size an air purifier for an entire house, the easiest method would be to look at the paperwork from when you bought the home. This should include the total square footage for your house.
If you can’t find this documentation easily, a simple method is to go outside and measure the length and width of your outside walls. Then multiple that number by the number of levels your home has. For example, if the outside square footage equals 1,200 sq. ft. and you have a two level home, this would be 1,200 x 2 = 2,400 sq. ft.
Finally, Match the Sq. Ft. Rating on the Air Purifier to Your Space
Air purifiers come in all shapes and sizes and carry a maximum sq. ft. rating on their specifications list.
If you’re looking to buy a product just to purify your bedroom or living room, it doesn’t make sense for you to buy a device that can clean a maximum of 3,500 sq. ft. Not only will this product be too powerful for the space, it will actually cost you more money to operate. It makes more sense to get an air purifier that is properly sized for your application.
If your room measures 150 sq. ft. then get an air purifier that indicates a rating that is at or just above this number. A 200 or 250 sq. ft. rating would be just as efficient as one that measures 150 sq. ft exactly.
What you also don’t want to do is buy a product that doesn’t meet your particular area’s square footage. Buying a device in order to save money that can only purify a space up to 80 sq. ft. would be a waste of your investment, since it won’t be able to purify that large of a space.
If you’re trying to buy a product to purify your entire house, yet you can’t find a product that has a high enough sq. ft. rating, such as 5,000 sq. ft., you’ll need to to make some compromises. Instead of trying to purify your house with one device, it makes more sense to break your home up into small square footage sections and find a device that will work well for this size.
For example, if each level measures 1,500 sq. ft. in a 3 level home, consider getting an air purifier that is sized to purify 1,500 sq. ft. Then buy three of these devices and place one on each level of your home. This way you can ensure that you are optimizing the efficiency of each device.
