Most air purifiers are built for single-room air cleaning, but there are a lot of houses that have a popular open concept plan.  Here’s where the larger ones (over 400sq ft coverage) come into play.  Open floor plans usually combine the kitchen and the family room into a visual flowing open space which is perfect for entertaining or keeping tabs on the kids!  With all the contaminants inside your home, why not make it a bit healthier.  Because basically… You need a large room air purifier, plus Who doesn’t like open concept floor plans!  the majority of today’s home layouts include open concept living!

don’t forget…  there’s more mold and dander floating around your home in the wetter seasons!  An air purifier would make a big difference when the windows and doors are always shut!  

All the purifiers in this post are made for larger rooms but, If you have a beautiful large open concept home then check out the Best large room Air Purifiers recommendation near the bottom of this article!

Air purifiers for large rooms

So… maybe you don’t have an open concept style home.  The square footage of a home as calculated by air purifier manufacturers.  They figure using a standard 8-foot ceiling.  example:  A 15’x20′ room has 300 square feet. but if you have 16-foot ceilings you better double that total so it covers 600 square feet!

Best large room Air Purifiers

I can only guess that the picture on the left is at least 25’x30′. that’s 750 sq. ft!   now see how high the ceiling is… probably 12 feet tall!  so I would recommend getting a purifier that could cover 4 more feet of the ceiling over the standard height of 8′. the math would look like this… 750+375=1126sq.ft.  The extra 375 is for the ceiling being 4 feet taller than the standard 8 feet, so we added on half of 750.

I hope you understand this little math lesson!  An air purifier that covers 1100 sq ft would probably work great in this example.

Some things to remember about Air Purifiers

  1. Dust, pollen, pet dander, mold spores, and dust mite feces can act as allergens, triggering allergies in sensitive people. Smoke particles and volatile organic compounds (VOCs) can pose a risk to health. Exposure to various components such as VOCs increases the likelihood of experiencing symptoms of sick building syndrome. (Courtesy of Wikipedia)
  2. Make sure to check out the filter life for the air purifier of your choice.  The filters on the larger units can last up to 2+ years.
  3. If you can’t measure the square footage of your room(s), just make sure your estimate includes the other room if you have an open concept floor plan or a higher ceiling if you have one!
  4. Any of these Best large room Air Purifiers, when set to low a speed, are usually less than 35 decibels.
