Airpura F414 Air Purifier

Airpura rates this machine for up to 1,000 sq ft at two air changes an hour, with 8-foot ceilings. For four air changes, which is what we suggest for smoke, asthma or chemical sensitivity, plan on about 500 sq ft.

• The F614 ($1,099.98) moves 560 CFM and is rated by Airpura for 2,000 sq ft at two air changes an hour.
• The F714 ($1,249.98) moves 635 CFM and is rated by Airpura for 2,500 sq ft at two air changes an hour.
• The F400 ($669.98) is the same machine with a True HEPA filter, 99.97% at 0.3 microns, in place of Super HEPA at 99.99%.

Airpura filter life varies by model and usage. Airpura rates the carbon filter at about two years of continuous use in a typical home. HEPA and pre-filters have their own replacement schedules. Replacement filters are available on our filters page. Running the unit below its rated capacity meaningfully extends filter life.

The 400 series has a three-speed fan. The lowest setting is the quietest and suits overnight use; the highest is meant for clearing a room quickly. See our quiet bedroom guide for Airpura's published decibel figures.

No. This unit uses only mechanical filtration — no ionizer, no UV, no ozone generator. That matters for people with asthma or chemical sensitivity, because ozone is a known airway irritant. Airpura does build UV-equipped machines, and they are gathered in the UV air purifiers collection — this is not one of them.

Yes. Austin Air and Airpura units are used by patients with asthma, allergies, and chemical sensitivity. The True HEPA captures particle-class triggers and the activated carbon addresses VOCs, odors, and chemical compounds. No ionizer, no ozone — safe for respiratory conditions. For MCS specifically, the HealthMate Plus or Airpura C600 have the most relevant specifications.

Yes. Airpura units are designed for continuous residential operation. The steel-body construction and quality motor components are built for this use case. The 400 series has three fan speeds, and a low to medium setting suits continuous use. Continuous operation at a moderate speed outperforms intermittent high-speed runs for maintaining consistent indoor air quality.
