Airpura F400 and F414 air purifiers cover 1000 sq ft (depending on model and speed) and traps formaldehydes, airborne chemicals, and VOCs with enhanced, impregnated, activated carbon as well as particles with its true metal-capped True HEPA filter. Some of the prime chemicals filtered which can cause moderate to severe health issues like headaches, drowsiness, and rhinitis are formaldehydes, ammonias, pesticides, benzene and toulene.
If you loved the larger F700 or F714, then you will love the newer F400 and F414 models designed for smaller spaces.
Airpura F400 and F414: Formaldehyde and VOC Air Purifiers for Smaller Spaces
The Airpura F400 and F414 air purifiers are built for rooms where formaldehyde, airborne chemicals, and VOCs are the main concern. Each unit pairs 8 lbs of enhanced activated carbon impregnated with potassium permanganate with a metal-capped HEPA filter, so chemical gases are adsorbed and fine particles are captured as air moves through the unit.
Modern homes and work areas release a steady stream of chemicals. Pressed-wood furniture, cabinetry, flooring, carpet, paint, and cleaning products can off-gas formaldehyde, ammonia, benzene, toluene, and other VOCs, and pesticides can drift in from outdoors. These chemicals can contribute to health issues ranging from moderate to severe, such as headaches, drowsiness, and rhinitis. The F-series carbon is formulated to target formaldehyde, while the HEPA filter handles dust, pollen, pet dander, and other airborne particles.
Why Impregnated Carbon for Formaldehyde?
Formaldehyde is a small, lightweight molecule that standard activated carbon has a hard time holding on to. That's why the F400 and F414 use carbon impregnated with potassium permanganate, which reacts with formaldehyde and similar light gases rather than relying on adsorption alone. This gives you a carbon bed better suited to the chemicals that off-gas from new building materials, furniture, and finishes.
Choose Your Particle Filter
Airpura F400: Medical-grade True HEPA, capturing 99.97% of particles as small as 0.3 microns.
Airpura F414: H14 SuperHEPA, capturing 99.99% of particles as small as 0.1 microns, a strong choice for allergy and asthma sufferers and people with heightened sensitivities.
Sizing Your F400 / F414
At high speed, the F400 / F414 delivers about 2 air changes per hour (ACH) in 1,000 sq. ft. with 8-foot ceilings. The number of air changes you need varies widely, and there are many rules of thumb. For example, clients with allergies or asthma often aim for 3–7 ACH, while areas with heavy VOCs or smoke may even call for 10–12 ACH. The right number for you depends on what the contaminant is, how heavy it is, how quickly it's coming in, how much filtration you want, and your own sensitivities.
When formaldehyde and other VOCs are your main concern, size the unit on medium speed so air passes through the carbon more slowly, and make sure it can clean the air faster than the source releases chemicals. You can check your own room with our Air Changes per Hour Calculator, or contact us, and we'll help you find the right fit.
If you need high air changes in a small room, more than one F400 / F414 or an Airpura F600 works better than a 700-series unit, which can draw its own clean air back in. For larger spaces, the Airpura F700 offers the same F-series carbon in a bigger unit.

Not sure how many air changes your space needs? Every person and situation is different, and heavy VOC or smoke areas may even call for 10–12 ACH. If formaldehyde and other VOCs are your goal, calculate on medium speed. Try our Air Changes per Hour Calculator or give us a call at (888) 231-1463.
If the F700 or F714 is too large, the F400 and F414 are excellent options.

These are just some of the uses of this unit. Many contaminants fall into more than one unit so if you\'d like assistance finding the best unit for your needs, please contact us.
Also keep in mind that numerous factors come into play when considering an air purifier such as but not limited to the contaminants, coverage (sufficient air changes for the level of off gasing), speed of off-gasing, particulate matter, sensitivities of the consumer and much more.
The usages shown above are simply suggestions. Air Purification is not a black-and-white science. There is a lot of gray area that affects the results such as things that are out of our control like humidity or even the location of the unit. I wish there was just 1 unit for every need, it would make our job much easier, but there are trade-offs like sound for power and budget for filtration.
Don\'t hesitate to ask especially if the contaminant is high.
Airpura Difference
Unique Features That Make Airpura Different from Many Air Purifier Companies
Airpura air purifiers are built differently from many units on the market, with a focus on clean construction, deep filtration you can customize, and long-term durability.
Clean Construction
All-metal housing: Powder-coated steel instead of plastic, so no plastic vapors are emitted.
Motor out of the airflow: Many air purifiers blow the clean air over the motor, where it can pick up impurities. Airpura keeps the motor out of the airflow.
Electrical parts in a sealed chamber: Kept away from the airflow, which increases safety and prevents off-gassing.
Pressure-sealed filter chamber: Airpura’s unique pressure seal keeps air from slipping around the filters, so it passes through them.
Neoprene gaskets: Seal the filter chamber, with felt available on request (custom made for the unit, so it may lengthen ship time).
Deep, Customizable Filtration
Deep activated carbon beds: Up to 26 lbs of activated carbon, depending on model, with airflow and bed depth calibrated for proper contact time.
Carbon options: On carbon models, the standard carbon can be swapped for V, F, S or anthracite carbon for an additional charge, to target specific chemicals.
HEPA options: True HEPA or HEPA Barrier, depending on the model; H14 SuperHEPA on the 414, 614 and 714 models; and a 100 sq. ft. True HEPA on the I series, the largest HEPA in the Airpura line.
UV and PCO options: UV germicidal lamps on the UV series, TitanClean photocatalytic oxidation with UV on the P series, and a UV upgrade on the I series.
Power and Control
Delivered airflow (after the filters): Estimated from low to high. Delivered airflow varies with each filter configuration.
400 series: 40–260 CFM
600 series: 100–412 CFM (366–412 CFM on high, depending on model)
700 series: 88–450 CFM
Speed control: Three speeds on the 400 series and variable speed on the 600 and 700 series.
Superior dwell time: The integrated impeller/motor, speed control and unimpeded airflow let you set the airflow precisely, so the air gets the time it needs with the filters.
Built to Last
Warranty on residential units: 5 years parts and 10 years labor.
Warranty on industrial/commercial units: 2 years parts and 5 years labor.
Made in: Canada.
Whole home options: R, V, UV, P, C and I models are also available as whole home units, installed by your local HVAC specialist.
