AirPura V400 air purifier is an Excellent Air Purifier focusing of removing chemicals (VOCs) and particulate matter for small spaces. Enhanced special blend carbon adsorbs VOCs and specific chemicals together with true HEPA for particles. Superior air flow and dwell time with the largest CFM in a portable unit. Coverage of 2 ACH for 1000 sq ft depending on model and speed.
The Airpura V400 and V414 are compact, high-powered air purifiers built to reduce airborne chemicals, VOCs, gases, and odors along with fine particles. Each unit holds 8 lbs of Airpura's enhanced, impregnated carbon blend, which adsorbs a wider range of VOCs and specific chemicals than standard activated carbon. That makes the V-series a strong choice for bedrooms, nurseries, home offices, and other smaller spaces where chemical sensitivity is the main concern. Both models cover up to 1,000 sq. ft. at 2 air changes per hour (ACH), depending on fan speed, and run as quiet as 32 dB on low.
The V400 pairs 8 lbs of enhanced carbon with a 40 sq. ft. medical-grade True HEPA filter that captures 99.97% of particles as small as 0.3 microns. It's a balanced choice for households that want strong chemical and VOC reduction plus dependable protection from dust, pollen, pet dander, and mold spores.
The V414 uses the same enhanced carbon bed, all-metal housing, and 395 CFM motor as the V400, but upgrades the particle filter to an H14 Super HEPA that captures 99.99% of particles as small as 0.1 microns. We recommend the V414 for allergy and asthma sufferers, mold concerns, fine smoke particles, and anyone with Multiple Chemical Sensitivities (MCS) who wants the highest level of particle capture alongside chemical reduction.
The only difference between the two units is the particle filter. Everything else, including the housing, motor, pre-filter, and 8 lbs of enhanced carbon, is the same.
Both models use the same pre-filter and carbon filter. The 414 H14 HEPA filter also fits the V400, so you can upgrade to Super HEPA later if your needs change.
Carbon and HEPA do different jobs. The carbon bed adsorbs VOCs, gases, and odors, while the HEPA filter captures particles like mold spores, pollen, and pet dander. The V400 and V414 give you both in one compact unit, with the same filtration quality and configuration as Airpura's larger V600 and V614. The variable-speed motor lets you set airflow for longer dwell time in the carbon bed, which improves VOC adsorption.
At high speed, the V400 / V414 delivers about 2 air changes per hour in 1,000 sq. ft. with 8-foot ceilings. For heavier chemical loads, more than 1 air change is necessary, and our clients frequently aim for 5 or more ACH depending on square footage. At 5 ACH, the V400 / V414 is a good fit for rooms up to roughly 390 sq. ft. You can check your own room with our Air Changes per Hour Calculator. If your main concern is general particles and household odors rather than specific chemicals, the Airpura R400 & R414 uses standard activated carbon at a lower price.
| Pre-filter | Clean every 3–6 months, change every 6–12 months |
| Carbon filter | Up to 2 years, depending on usage and contaminants |
| HEPA filter | Up to 5 years, depending on usage and contaminants |
Note: Filter maintenance is based on standard usage and average contaminants. Depending on your situation, filters may need to be changed more or less often.
The Airpura V400 and V414 are two separate units built on the same compact, all-metal platform. Both pair 8 lbs of Airpura's enhanced, impregnated carbon blend for VOCs, specific chemicals, gases, and odors with high-efficiency particle filtration. The difference is the particle filter: the V400 uses a True HEPA filter, and the V414 uses an upgraded H14 Super HEPA filter for a higher level of particle capture.

These are just some of the uses for this unit. Many contaminants are a good fit for more than one unit, so if you\'d like help finding the best one for your needs, please contact us.
Many factors come into play when choosing an air purifier, including the contaminants, coverage (enough air changes for the level of off-gassing), how quickly things are off-gassing, particulate matter, and your own sensitivities. The uses above are suggestions. Air purification isn\'t a black-and-white science, and things outside our control, like humidity or where the unit is placed, affect results. We wish there were one unit for every need, but there are always trade-offs, like sound versus power and budget versus filtration.
Do not hesitate to ask, especially if your contaminant levels are high.
Superior Dwell Time: The 395 CFM impeller/motor combined with the variable speed control and unimpeded airflow of the Airpura 400 series allows the airflow to be set precisely and achieve maximum results.
The 4-series allows our clients not only to enjoy the same high-quality filtration as the 7-series configurations but just in a smaller, compact unit.
