Which Blueair air purifier is best?
Whether you suffer from allergies or believe the air in your space could be cleaner, air purifiers can improve the air quality inside your home. One of the better brands of air purifiers is Blueair. They have a dozen models available that cover rooms of every size, but their best option for coverage and cost is the Blueair Blue Pure 311. It can tackle rooms of up to 400 square feet and will filter the air up to four times an hour.
What to know before you buy a Blueair air purifier
Portable vs. whole home
Blueair air purifiers are all portable models, but it’s important to understand the difference between a portable purifier and a whole-home purifier.
- Portable models will only clean one room. They may be able to clean surrounding rooms as well, but with less efficacy. You can move them from room to room as needed without requiring any kind of special setup; just plug them in and let them work.
- Whole-home models attach to existing ducts or furnaces to purify the air as it travels around your home. These are expensive and are difficult to install.
Coverage refers to how much space a Blueair air purifier purifies efficiently and is measured in square feet. Blueair models typically cover about 150-750 square feet, though most cover 500 square feet or less.
It’s important to note that the coverage range only refers to coverage in one room. For example, if you live in a home with three or four rooms and want to purify the entire space, an air purifier will only clean the area it’s contained in. Surrounding rooms may get some coverage, but it won’t be as effective.
What to look for in a quality Blueair air purifier
Companies measure how much air goes through the air purifier in two ways: air change per hour or cubic feet per minute.
- ACH numbers note how many times the air from an entire room will pass through the purifier in one hour. For example, an ACH of four will clean the entire room’s air four times an hour.
- CFM numbers note how much space it purifies each minute, measured in cubic feet. It’s more precise than ACH, but you have to calculate how long the purifier takes to complete one cycle. First, find the cubic feet of your room, then divide by the CFM.
Blueair air purifiers use fans to move air through their filters, and these fans generate some noise. The more powerful the fans, the more noise it creates. That said, very few models generate more than 60 decibels, and the lowest setting is whisper-quiet.
How much you can expect to spend on a Blueair air purifier
Most Blueair air purifiers cost $300 or less and handle up to medium-sized rooms. Large rooms will need a bigger model, which typically costs between $400-$600. Huge, open spaces will need an extra-large model, usually costing $600 or more.
Blueair air purifier FAQ
How does a Blueair air purifier work?
A. Blueair air purifiers draw air using fans, filtering out the particles before sending the clean air back out. The process of drawing in and expelling air creates a cycle of smooth airflow in the room. This process helps filter all the air in the room rather than just the air in the purifier’s immediate surroundings.
What does a Blueair air purifier filter out?
A. Blueair air purifiers will filter out the same airborne contaminants as other air purifiers. This includes dust, pollen, mold, smoke and pet-related contaminants such as hair and dander. However, they don’t filter out fumes like those from paint or glue.
How much does it cost to operate a Blueair air purifier?
A. That depends on the model you buy, how contaminated the air is and how well you maintain the purifier. It can cost less than $50 a year or as much as several hundred dollars a year. Many Blueair models are cost-effective since they use washable and reusable filters. They are also Energy Star certified, meaning they use as little electricity as possible.
