You can create an allergy free haven with the right room air purifier, and finding one doesn't have to be complicated with our simple steps and well researched recommendations:
You want all the air in your room to go through the room air purifier ideally six times per hour...
Measure the width, depth and height of your room and multiply the three figures. If you have a room that is 12.5 wide by 10 deep with 8 foot ceilings, 12.5 x 10 x 8 = 1000 cubic feet.
Multiply that number by four to get four air changes per hour minimum....in this case, 1000 x 4 = 4000 cubic feet per hour.
Then, compare your total the cubic feet per minute stats on the room air purifier you are considering. With air cleaners that have multiple fan speeds, consider that you will probably run the unit on middle to lower speeds, and so the advertised top capacity of an air purifier may not apply. Very few people want the noise of running their air filter on high speed.
Confused? I've done the math for you. Just measure your room and skip to my recommendations below.
Or, divide the cubic feet of your final number by 60 to get the cubic feet per minute you need out of a room air purifier.
So in the end, it looks like this:
12.5 width x 10 depth x 8 height = 1000 x 4 air changes per hour = 4000 divided by 60 (to reduce to cubic feet per minute) = 67 cubic feet per minute performance needed, minimum out of your air purifer.
This is an easy step.
Unless you have special needs such as filtering out Volatile Organic Compounds, or have extreme sensitivities to chemicals, all the air purifiers below will work well for common allergens.
If you do have special needs, simply move to those recommendations instead...
If you're buying for a bedroom, you may want to considerhow noisy the unit is. The Blueairs are quietest and therefore best for most bedrooms.
(They also have the best looking design, in my opinion)
Price may also be an factor.
My recommendations well exceed the minimum 4 changes per hour at medium to low speeds so that you have squeaky clean air and breath pure to live your best:
