Matching an air purifier to room size and type
Matching the performance of an air purifier to the size and type of your room is essential for maximizing its effectiveness. A purifier that's too small may struggle to adequately clean the air in larger spaces, while one that's too powerful for a small room could be unnecessarily loud and consume more energy than needed. Let’s not forget, different types of rooms have different air purification needs depending on what happens in them. By selecting the right purifier for your specific circumstances, you can ensure that every breath you take brings you the clean, refreshing air you deserve.
What defines a room's size?
While square footage is an important aspect of assessing room size, air purification requires considering another critical factor: ceiling height. Alongside the room's width and length, its height determines cubic volume, indicating the amount of air within a room. This measurement is essential for determining your needs when it comes to the amount of pollutants and unwanted odors the purifier might encounter there.
Measuring your room
If you’re not aware already of the size of the room you’re looking to treat with an air purifier, let’s find out its square footage and cubic volume with these simple steps:
- Use a tape measure to determine the length of the longest wall and designate it as the "length."
- Repeat the process for the shorter wall, designating it as the "width."
- Use the formula LENGTH x WIDTH = SQUARE FEET (or ft²) to find the room's square footage.
- Measure from the floor to the ceiling and designate this as the "height."
Use the formula LENGTH x WIDTH x HEIGHT = CUBIC FEET (or ft³) to calculate the room's cubic volume.
Irregularly shaped rooms can be measured by breaking them up into rectangles and measuring each part separately using the same method described above. Add the volumes of all the rectangular spaces together to determine the room’s total volume.

Air purifiers for small rooms
Air purifiers for small rooms are essential for the little spaces that have a big place in our lives, but what makes a small room small? Let’s recognize that not everyone has the same opinion when it comes to describing their living space. The geographical and economic diversity of the world we live in can influence our perceptions of room size.
When it comes to air purification, numbers become a more important factor than the labels we put on them. We have Swedish designed air purifiers for spaces that encompass areas between 92 to 250 square feet, and they’re perfect for anything from a storage area to home office or kitchen, even an entire living space that combines them all.
The Blue Pure 411i Max is a perfect air purifier for the spaces of this size and type. What could be better than getting the entire volume of air in a 250 square foot space in just over 12 minutes? A barely there presence with ultra quiet operation and a compact design that you can customize.
That’s right, the Blue Pure 411i Max is part of the only line of air purifiers that has a customizable fabric pre-filter, with four different Scandinavian inspired colors that allow you to personalize your air purifier to blend into your home with a compliment to your own taste. A Stockholm Fog pre-filter color is included. But don’t let all this sleekness fool you into thinking it’s not powerful. The Blue Pure 411i Max has a Clean Air Delivery Rate (CADR) of 112 Cubic Feet per Minute for all three of the most common air intruders — smoke, dust, and pollen.

Air purifiers for medium to large rooms
When it comes to elevating the air experience in medium to large spaces, versatility is key. These multifaceted areas that span across zones for living and dining to working, demand air purifiers that can adapt to diverse functions. When looking to place an air purifier in a medium sized or large room, prioritize models equipped with comprehensive filtration systems, remote control and monitoring capabilities, and adjustable settings. All are essential for effectively tackling the range of air challenges present in these dynamic environments. Additionally, the ability of our air purifiers blend into their surroundings ensures that they’ll complement the aesthetics of sizable rooms while delivering superior air quality in them.
