Earlier than you browse on-line or head to the shop, consider the method of shopping for an air air purifier as becoming your room for an air air purifier. Whereas we don’t use the phrase “horsepower” by way of air purifiers, by becoming your room, you’re actually on the lookout for air trade energy.
The principle query: Is that cute viral air air purifier highly effective sufficient to wash the air in your bed room or lounge? And the way does one determine that out? The primary half is doing third-grade math. You’ll need a tape measure. I used a primary 25-foot measure that I purchased at a ironmongery store years in the past. With the assistance of considered one of my youngsters, I measured the size of the room after which the width, after which multiplied the size occasions the width to get the realm or sq. footage.
Step 2: The Peak of Your Ceiling Issues
Although you’ve got discovered the realm of your room by doing the length-times-width formulation, you’re not performed. And earlier than we go any additional, the peak customary utilized in many air air purifier calculations—often called the clear air supply price, or CADR—is an 8-foot-high ceiling. Whenever you add top by multiplying the size occasions the width occasions the peak, it offers you the room’s quantity or cubic sq. footage. Typically, relying on the mannequin of air air purifier, you’ll want the cubic sq. footage; typically you will want solely the sq. footage.
Sure, determining the sizing of an air air purifier within the US is complicated resulting from American measurement techniques—Nate Bargatze explains it effectively on this skit from Saturday Night time Reside. I digress. Getting again to your room: Rooms with excessive ceilings equivalent to A-frames, cathedral ceilings, double top ceilings, and the like could have the added burden of determining the cubic sq. ft of their room, as a result of it will imply you want both an even bigger air air purifier or two purifiers to wash the air.
Step 3: It’s All Concerning the Numbers

An important room is the one you spend probably the most time in. For most individuals, that’s the bed room. Say you’ve discovered your bed room measurement and it’s 200 sq. ft, and your ceiling top is round 8 ft. You discover an air air purifier with an marketed CADR of 4 air exchanges an hour for 200 sq. ft. That’s not going to be robust sufficient. Why? Most air purifiers take advantage of noise at their highest setting, like 50 decibels or increased—just like a contemporary fridge. Which means whenever you run that very same air air purifier at a decrease setting, it gained’t effectively clear the air in that 200-square-foot room.
