The Airpura R400 air purifier is a compact, high-powered unit ideal for bedrooms, nurseries, offices, and other small spaces, thanks to its strong performance and low sound levels. It combines True HEPA with 8 lbs of activated carbon to target airborne particles, VOCs, gases, and odors, with an optional R414 H14 Super HEPA upgrade for even finer filtration.
The Airpura R400 air purifier and the Airpura R414 air purifier are two compact, high-powered models built for bedrooms, nurseries, home offices, and other smaller spaces. Each one pairs a HEPA filter with 8 lbs of activated carbon, so it captures airborne particles and also adsorbs the VOCs, chemicals, gases, and odors that HEPA-only purifiers miss. Despite their small footprint, both models share the same quality construction as Airpura's larger R600 and R700 units, and they run quietly enough for overnight use.
The Airpura R400 air purifier is built around a medical-grade True HEPA filter that traps 99.97% of particles as small as 0.3 microns. It's an excellent everyday choice for homes, bedrooms, nurseries, and offices where you want reliable protection from dust, pollen, pet dander, mold spores, and common household odors.
The Airpura R414 air purifier steps up to an H14 Super HEPA filter that traps 99.99% of particles as small as 0.1 microns, for even finer particle capture than the R400. The R414 is an excellent choice for dental and medical offices, clinics, nursing homes, and anyone with severe allergies, asthma, or heightened sensitivities.
The difference between the R400 and the R414 is the HEPA filter. The Airpura R400 uses a True HEPA filter that traps 99.97% of particles as small as 0.3 microns, a strong choice for everyday home use. The Airpura R414 uses an H14 Super HEPA filter that traps 99.99% of particles as small as 0.1 microns, for finer particle capture in medical and dental settings or for people with severe allergies and sensitivities. Both models include 8 lbs of activated carbon, the same all-metal construction, and the same quiet operation.
Many air purifiers focus on either particles or odors, but the R400 and R414 are each designed to handle both. The HEPA filter captures ultrafine particles such as mold spores, pollen, pet dander, and dust, while the deep activated carbon bed adsorbs VOCs, household chemicals, gases, and odors. This balanced approach helps bring relief to allergy and asthma sufferers and improves overall indoor air quality for better long-term health.
At 32 dB on low, the R400 and R414 are barely louder than a quiet room (about 30 dB), and they reach 52 dB on high when you want faster cleaning. Each unit stands 15.5" high, weighs just 23 lbs, and covers up to 1,000 sq ft at 2 air changes per hour, depending on fan speed. The all-metal housing prevents plastic off-gassing, and the motor sits outside the airflow, so cleaned air doesn't pass over it and pick up impurities. Both models are made in Canada and backed by a 5-year parts and 10-year labor warranty on residential units.

If the R700 is too large, the R400 or R414 is an excellent option.
Ideal for Smaller Spaces:
Choose the R414 for the finest particle capture. Its H14 SuperHEPA filter captures particles as small as 0.1 microns, which makes it a great fit for allergy and asthma sufferers, mold concerns, fine smoke particles, and anyone with heightened sensitivities.
These are just some of the uses for these units. Many contaminants fall into more than one category, so if you\'d like help finding the best unit for your needs, please contact us.
Also keep in mind that many factors come into play when choosing an air purifier, including but not limited to the type of contaminants, coverage (enough air changes for the level of off-gassing), the speed of off-gassing, particulate matter, and the sensitivities of the people in the space.
The uses shown above are simply suggestions. Air purification is not a black-and-white science. There is a lot of gray area that affects results, including things outside our control like humidity or even where the unit is placed. We wish there were one unit for every need, since it would make our job much easier, but there are always trade-offs, like sound versus power and budget versus filtration.
Do not hesitate to ask, especially if 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.
